Guys, the city needs us. We were the ones who decided to be superheroes. Now's the time to be super.


Hiro Hamada is the main protagonist of the Big Hero 6 franchise, as well as the leader of the Big Hero 6 organization.

BackgroundEdit

Hiro Hamada is a half-Japanese, half-Caucasian boy who was raised with his older brother Tadashi by their aunt Cass following the death of their parents when Hiro was only 3 years old. Hiro was a born genius, being greatly advanced and surpassing all of his peers including his own brother on a variety of intellectual planes to the point where he found himself regularly skipping grades in order to continue his own "education." By the age of 13, he had graduated high school and subsequently tapped into and mastered a large mass of information and complex world concepts that most students enrolled in college were only just being introduced to.

Tadashi also took him to haunted houses for Halloween in many occasions.

Sometime in the past, Hiro became involved in bot-fighting that soon evolved into an outlet for his intellect, despite the negative social connotations the sport was notorious for. During this time he also became friends with the other bot-fighters such as Stan.

Official DescriptionEdit

Robotics prodigy Hiro Hamada has the mind of a genius—and the heart of a 14-year old: his state-of-the-art battle-bots dominate the underground bot fights held in the dark corners of San Fransokyo. Fortunately, big brother Tadashi redirects Hiro's brilliance, inspiring him to put his brain to the test in a quest to gain admission to the San Fransokyo Institute of Technology. When a tragic event changes everything, Hiro turns to a robot named Baymax, and they form an unbreakable bond—and two-sixths of a band of high-tech heroes on a very important mission.[2]

PersonalityEdit

Hiro Hamada is a carefree and free-spirited young man with intelligence and understanding far beyond his years. Because of this, he can be a bit brazen and cocky, but never to the point of arrogance. He is easily accepting of other people and doesn't seem to have much of a problem forming positive connections with those he comes into contact with.

There is a certain sincerity Hiro harbors that allows him to cohesively, effectively and firmly convey his feelings and ideas on a matter at hand to whoever is within earshot. The fullest extent of this sincerity comes out perhaps most predominantly around his brother, Tadashi Hamada. Despite their scuffles and brotherly banter, the words exchanged between them are always filled with their true and barest thoughts, concerns, insecurities, and intentions. They never pull any punches when it comes to relating to each other what they think and feel on either the current situation or the topic at hand and their bond is only stronger because of it.

Despite his cool, carefree, yet hot-blooded and bold nature, Hiro has been shown to have a much softer disposition that hasn't been shown willingly displayed to anyone save for Baymax and Aunt Cass. Even so, his caring and sympathetic disposition are evident both in the way he interacts with and handles his relationships with his family and team members. He is generally always looking out for the safety and welfare of those around him and taking into consideration their individual and personal conditions before finally focusing on himself, even if he suffers a bit as a result of it. Even when Hiro is shown to have been wronged, he takes it in starkly collected stride, taking the adequate time to handle the situation with a calm, level and yet fiercely determined and driven head.

His working ways are pretty chaotic, and as a genius he does not mind making a mess as long as he gets things done. This came into conflict with Wasabi when both had to work on a school project for Professor Granville. Though both are great friends and teammates, Hiro's attitude did not settle well with Wasabi's overly-organized and perfectionist ways, which made them both even want to bail out with excuses. However, they managed to work it out and the Mech Suit they built was impressive to Granville.

Sometimes though, he gives up easily when ideas don't come to his mind right away or makes several failed attempts, then he gets nervous that he might not be good enough anymore, but thanks to his friends he has been able to overcome these issues.

However, underneath this heart of gold lies a darker and more ruthless potential. On the flip-side of this caring, loving, direct and to the point disposition, Hiro has maintained a very staunch no-nonsense policy when it comes to those who intentionally cause harm and misfortune to those he cares for and loves. At one point, the full force of this sentiment would come to a frightening culmination if the act was particularly heinous. In the case of such an event, Hiro for all intents and purposes would lock down on immediate retribution for said crime and it would take a certain intervention to truly calm his rage. This has now altogether ceased to be an issue, with Hiro perhaps becoming even more level-headed and considerate than he was before.

AppearanceEdit

Hiro is a young adolescent boy of Japanese descent and is approximately five feet tall with a lean and slender frame. He has tousled, jet-black hair, almond-shaped brown eyes, somewhat thick eyelashes and eyebrows, light skin and a slight gap in his teeth.

He can be most consistently found in some combination of casual shirts, cargo capris, and Converse sneakers all likely topped off with a blue hoodie.

When geared up as a superhero, Hiro dons a battle-ready outfit showcasing indigo armor. Under this armor, he wears a black protective two-piece suit that covers most of his body down to his knees along with black knee pads and steel-toe black sneakers, both of which have red magnetic circles which allow him to link to magnetic ports on the back of Baymax. On his hands, he wears thick, forearm-reaching, black and indigo padded gauntlets that sport the same red magnetic circle on the palms.

His super-suit is altered in the series. His helmet's visor is transparent in the film, but was retconned to be orange-tinted in the show. His sneakers have been replaced with black steel-toe combat boots, the pockets on his belt are obsolete, and his black pants fully cover his legs.

His red shirt in the series does not have the humanoid robot like the movie and he does not wear an under shirt and also he does not have his other shirts that he wore with his cargo capris in the movie. He also does not zip up his hoodie in the series.

Powers and AbilitiesEdit

  • Genius-level intellect: Hiro's true potential lies within his genius. He is highly innovative, and has the power to create inventions from inspiration; from small but powerful battle-bots to state-of-the-art super suits. He also has intimate knowledge of his inventions and can coordinate on a complex level of thought. Hiro's intelligence is so high that he was even able to recreate items with impeccable detail, such as Baymax.
  • Martial Arts: In a picture of Hiro and Tadashi as children, it appears that Hiro learned martial arts at a young age but he is never shown using it in battle, although he does seem to recognize its codes and rules as shown when training with Baymax.
  • Magnetism: When wearing his suit, the magnetic pads on Hiro generate magnetic waves to help him cling to metallic surfaces. Although this is used primarily to hold onto Baymax whenever the robot takes flight, Hiro can use it for offensive purposes, such as attracting or deflecting metallic objects. It's a short-distance range however, so he has to be close to any object he'd want to grab.
  • Superhuman strength: Hiro temporarily gained this ability in "Kentucky Kaiju" by creating a Nano-Dex shirt and wearing it along with his armor, after he felt useless for being the only Big Hero 6 member without attack gear.

EquipmentEdit

While his suit does not enhance his natural abilities, it does enable him to ride Baymax in flight, as well as partial protection from destruction. His helmet is also equipped with a communication device, enabling him contact with the rest of the team members despite their distance.

  • Computer interface: Integrated into his suit's gloves, Hiro uses a miniature computer to hack, track down and program many things.
  • Plasma blades: In "Killer App", the animatronic Noodle Burger Boy obtained data about the team and was able to predict their attacks based on their suits' abilities and moves. Hiro and Wasabi got the idea to switch suits and attack the robot this way, and so Hiro wore Wasabi's blade-equipped armor to fight against the robot and their stolen mech suit. He was shown to be skillful with it, too. He also wears Wasabi's armor by accident in Kentucky Kaiju.
  • Nano-Dex shirt: In "Kentucky Kaiju", he wore this shirt, made of a special fabric, to enhance his own strength and take on villains himself. Though he was later unable to take it off because it was way too tight, after fighting the Kentucky Kaiju it malfunctioned and was finally able to get rid of it.
  • Tadashi's Scooter: The motorbike that originally belonged to his brother which Hiro later took and sometimes uses for transport, also giving it upgrades.

Battle SuitsEdit

Hiro has created different kinds of armored suits for himself and his friends, some of which are used only for special occasions.

  • Super Armor: Hiro's default armor. He uses it most of the time when he operates with Big Hero 6. It is mostly purple with red, as well as some black parts. It features magnets on the gloves.
  • Wasabi's Armor: It is Wasabi's default armor which Hiro used once because of Noodle Burger Boy's prediction algorithm that allows the robot to predict the moves of Big Hero 6 when they are wearing their respective armors.
  • Ultra Armor: Hiro gave himself and his friends upgraded armors made of titanium so they could fight Orso Knox. His armor was silver with purple trimmings.
  • Submarine Armor: He and Baymax use special underwater armors, first created to get Wasabi's car back from the bottom of the bay. Their function is similar to a diving suit, containing an air supply, palmed hands and diving feet.

HistoryEdit

Big Hero 6Edit

When Hiro is 14 years old, he goes to an illegal bot-fight to win easy money by pretending to be unskilled, bluffing all along. Unfortunately, he challenges the gangster and bot-fight champion Mr. Yama, first allowing Yama's Little Yama to defeat Hiro's own Megabot only so Yama would stake more money for a second round, then Hiro shows his real genius and effortlessly destroys Little Yama with Megabot, claiming victory. Yama quickly realizes he had been swindled and calls his criminal henchmen to beat up Hiro, though he is immediately rescued by his brother, Tadashi, who took him away with his scooter. Despite their efforts to escape from Yama, both parties along with everyone else involved with the event are caught, arrested and subsequently thrown in jail.

Thanks to their Aunt Cass, Hiro and Tadashi are released that same night with Cass scolding them as the Hamadas return home. The two are able to bypass punishment, but a frustrated Tadashi scolds Hiro on his bot-fighting obsession and insists that he put his intelligence to better use, recommending the San Fransokyo Institute of Technology. Hiro scoffs at the idea, jokingly noting the pointlessness of the effort and makes an attempt to join another bot fight as his ample winnings from his previous victory had been confiscated by the police. Tadashi apparently gives up and asks if he can give him a ride, but ends up taking him to the university.

Relenting to his brother's wishes, Hiro meets Tadashi's closest friends — Honey Lemon (a hyperactive chemistry expert), Go Go Tomago (a sassy adrenaline junkie), Wasabi (a neurotic neat freak) and Fred (a hopeless fanboy with a love of comics and Japanese Kaiju). Despite his reservations over what he had initially dubbed the "Nerd Lab," he finds himself shamelessly impressed and enthralled with the diverse projects and inventions of the quirky band of scientists. Tadashi takes Hiro to his lab where he introduces him to Baymax, an inflatable white robot, programmed to be a personal healthcare companion and created as a means to heal the sick and injured. Tadashi explains that Baymax was a healthcare nursing product meant to help people around the world. Baymax functionality relies on a green card which houses all of Baymax's healthcare programming, which, according to Tadashi, makes Baymax who he is. Immediately after leaving the lab, the two run into the school's Head of Robotics, Professor Callaghan. With his help, Tadashi finally manages to convince Hiro to enroll in the Institute, Callaghan claiming that a school is a place where the boundaries of robotics are pushed and geniuses put their brains to the test in order to shape the future. Realizing that this is the very same Callaghan who invented the base technology comprising the robot that he uses for bot fighting, his words instantly strike Hiro and after departing the school, he confesses his burning desire to join the Institute.

According to Tadashi, the school holds an annual convention where up-and-coming geniuses are meant to showcase new creations. Of course assuming that they haven't already applied, been accepted and enrolled, those who impress Callaghan will be immediately accepted into the school. Tadashi advises Hiro to concoct a creation to do just that. Hiro runs into a creator's block as he aspires to create something specifically brand new, jaw-dropping and ground-breaking. Comically over-exaggerating his unfortunate predicament, Hiro takes a mental break of sorts to mull over his thoughts before Tadashi reminds him to look for another angle, eventually leading to Hiro's breakthrough a bit sooner than later. Noticing something about his battle-bot, Hiro instantly gets an idea and immediately gets to business. After a period of work and planning, Hiro invents the Microbots--miniature robots capable of forming anything that comes to one's mind via the use of a telepathic headband transmitter. Confident in his creation, Hiro takes his invention and showcases them at the convention. Though nervous at first, Tadashi silently helps ease his nerves, resulting in a fantastic showcase that thoroughly impresses both Callaghan and famous tech-guru Alistair Krei. Krei offers Hiro vast wealth in exchange for ownership over the Microbots, an idea Hiro seems visibly hesitant about considering. Callaghan interferes with the offer by accusing Krei of using technology and science for selfish reasons, advising Hiro to deny the offer, which Hiro does. A frustrated Krei leaves the scene while Callaghan congratulates Hiro on his success by granting him admission into the school.

In celebration, Cass offers to take Hiro, Tadashi, and their friends back to Lucky Cat Café for a free dinner. Before they leave, Tadashi and Hiro spend time talking out Hiro's recent success. Tadashi congratulates his brother on his success, proud to see him use his genius for bigger things in life. Suddenly, the school's fire alarm goes off, prompting the two to investigate. Upon arrival, they find the Showcase Hall in flames. They run into one woman fleeing the blaze who tells the boys that Professor Callaghan is still inside. Tadashi attempts to go help get him out, but Hiro stops him, silently urging him to think about the situation. After a moment's consideration, Tadashi insists, claiming that someone had to help. Not seconds after he rushes into the building, the fire reaches its peak and the facility violently explodes, rendering Hiro, who had attempted to go after his brother, unconscious and killing both Tadashi and Professor Callaghan. A funeral and memorial service are held, and Hiro falls into depression at the loss of his brother and best friend. As such, he remains largely secluded in his room, appreciative, but mostly unreceptive of his Aunt and friends' comforting messages.

Hiro accidentally stubs his toe and his outcry of pain summons Baymax, Tadashi's healthcare companion. Baymax explains that he heard the sound of distress and offers assistance. Hiro waves off his offer assuring the robot that he can deactivate, only to accidentally stumble upon one of his Microbots. Hiro is surprised to find it still active and curiously trying to reunite with the other bots. Hiro, believing that the rest of his Microbots and the transmitter were destroyed in the fire, ignores the bot's activity and dismisses it as a malfunctioning. Baymax claims that the robot wanted to go somewhere and takes Hiro's offhanded suggestion to find where to the extreme, actually leaving the premises of Hiro's room and taking to the streets. Hiro chases the wandering Baymax through the city and the two eventually find themselves in an abandoned warehouse. The two break in and they soon stumble upon a machine creating millions of Microbots. As Hiro investigates and ponders over the mysterious discovery, the Microbots rise and attack. Hiro and Baymax evade them and eventually encounter a dark, masked figure. The masked man pursues the duo, but they eventually escape at the last minute, immediately heading to the police station to report the attack.

The two give their claims to Desk Sergeant Gerson, who finds their story to be rubbish, thus denying them lawful assistance. Just then, Baymax begins to run low on battery power, forcing Hiro to leave the station and return home to have the robot charge. After sneaking past an oblivious Aunt Cass, Baymax begins to charge and Hiro takes a breather from the exhausting day. Just then, Baymax acknowledges Tadashi's disappearance, asking his whereabouts. Hiro reveals Tadashi's unfortunate demise, but the mention of the fire being an accident sparks an epiphany. After the encounter with Yokai, Hiro realizes that the fire was no accident and recruits Baymax into helping him take down the masked culprit, wanting to avenge his brother's death. As such, Baymax is given a few upgrades, including a super-suit equipped with martial arts battle programming and a new chip which gives him such abilities. After his new upgrades are put to the test, the two head out to find and capture Yokai. They arrive at the warehouse, only to find it vacant. However, using the last Microbot to track him, Hiro and Baymax are led to the docks, where they find the Yokai emerging from the fog with a massive piece of technology. The two go into silent hiding until Honey, Go Go, Wasabi and Fred arrive, having followed the two thereafter spotting them snooping about the city.

Hiro urges them to leave for their own safety before the group is attacked by Yokai. Baymax tries to battle the masked villain, only to be thrown onto the top of Wasabi's car. The gang retreats from the scene with Yokai immediately following behind them, leading into a chase throughout the city. Yokai makes several attempts to kill the team, but between Hiro's command of Baymax and Go Go's reckless driving, they manage to escape by driving off a ledge and into the bay, having Yokai believe them to be dead, prompting him to vanish once again. Baymax manages to rescue the team and bring them back to shore and Hiro suggests they needed a place to rest for the night and recover, at which point Fred welcomes them into his mansion. There, they discuss the true identity of Yokai and how to track him down and bring him to justice for his crimes against Hiro's brother. Baymax reveals that he scanned the man's body, but Go Go notes that with Baymax's scanner, it would take forever to scan every person in the city. Hiro agrees but notes that he only has to upgrade it. The team is apprehensive at first, bringing up the fact that they were all just "nerds." Hiro then doubles back, saying that in order to bring in a guy the caliber of Yokai, they would all need to be "upgraded." Reassured, the team bonds together under hero in order to capture who Hiro believes to be responsible for the fire. True to her character, Go Go was the first to vocally resonate with him, buckling down and getting ready face fear and help Hiro bring the supervillain to justice.

After some scientific modifications and training, the group of friends become a superhero group bent on taking down Yokai. To do so, the team believes his mask is his source of power and the objective is to retrieve the mask to cease his control over the bots. Baymax is the last to be upgraded and after his new super-suit is revealed, he and Hiro take a test flight for the first time throughout the city, eventually landing on one of the air balloons towering over the city and overlooking a sunset. Hiro and Baymax take the time to relax and bond for a short moment, which brings happiness to the boy. Realizing this, Baymax asks Hiro if he's satisfied with his care, as his true objective throughout their adventure is to ensure Hiro's happiness and satisfaction, claiming Hiro to be his patient. Hiro denies Baymax's suggestion and returns to the matter at hand.

After scanning the city to find a match to Yokai's health information, Baymax discovers a match on an island not far from the mainland. The team heads to the area, which is revealed to be an abandoned facility. There, they find a machine in the process of restoration but are unable to uncover what it is exactly. Soon enough, their snooping leads to a room with recordings taking place in the facility. After watching, they learn that the facility originally belonged to Alistair Krei and the machine was a portal meant to enhance transportation. The test subject, a woman named Abigail, was the first to try it out, but as she did, the machine malfunctioned. Instead of calling off the procedure, Krei insisted that they move forward, resulting in a tragic accident that left Abigail lost in the portal and apparently killed by the machine's destruction. The incident results in the closure of Krei's facility and the team then comes to the conclusion that Krei is responsible for stealing the Microbots in hopes of rebuilding his portals.

Just then, Yokai returns and attacks once more. A battle follows and in the process, Hiro accidentally removes the villain's kabuki mask. Yokai's true identity is then revealed to be Professor Callaghan. Callaghan confesses his crime of stealing the Microbots and reveals that he used them to escape the fire alive and unharmed. A heartbroken Hiro reveals that Tadashi died trying to save the professor, but Callaghan merely responds by blaming Tadashi for his own death. Furious, Hiro orders Baymax to kill Callaghan. Baymax denies such an action, explaining he's unable to bring harm to a human being, but Hiro, blinded by hatred and grief, removes the robot's healthcare chip, leaving only his programming of battle and destruction, thus sending him on a violent, mindless rampage in an attempt to kill the professor. Seeing this, Go Go, Fred and Wasabi try to fend off the bot and, in the mix of the chaos, Callaghan manages to escape.

Luckily, Honey recovers Baymax's healthcare chip and restores the robot to his original peaceful settings. Realizing what he's done, Baymax apologizes to the team for causing harm but Hiro berates them, blaming them for Callaghan's escape. The team retorts by explaining that the plan was never to kill Callaghan, but instead, to merely apprehend him. Leaving the team on the island out of anger, Hiro and Baymax return home to fix Baymax's suit. Baymax talks to Hiro about the situation of killing Callaghan, asking if his death would appease the boy. Instead of answering, with his mind clouded by thoughts of fury, revenge, sadness and the loss of Tadashi, Hiro breaks down in tears. Baymax comforts him by showing him videos of Tadashi, which he recorded during his creation process. Tadashi's presence and loving words bring enlightenment to Hiro, who thanks Baymax for his comfort. Honey, Go Go, Fred and Wasabi soon arrive as well. Instead of being upset with Hiro, they, too, comfort the boy, he says he is sorry for yelling at them and they understand that his actions were only out of grief and vow to bring Callaghan to justice and his four teammates forgive him. Before they set out, the team shows Hiro a recording they found, which reveals that Abigail was the daughter of Callaghan and the entire goal behind his villainy is to extract revenge on Alistair Krei.

The next day, Alistair Krei is in the middle of an important showcase, just as Yokai arrives and captures him. Yokai reveals himself to be Callaghan, and the villainous professor subsequently reveals his plot to use the newly-recreated portal to destroy both Krei's new building and Krei himself. Alistair tries to talk sense into the villain, explaining the incident with Abigail was an accident, but Callaghan ignores him and proceeds with his plot. Just then, Hiro and the team arrives on the scene. Instead of immediate attack, Hiro tries to sympathize with the professor, explaining the fact that extracting revenge isn't the way to handle his daughter's death, but Callaghan's fury gets the better of him, and his plans proceed. Hiro and the others battle the villain, aiming for Callaghan's mask, but Callaghan soon gets the upper hand with the help from the Microbots and leaves the team members to die as his plot is set in motion. As Hiro is being pulled towards the portal, his distressed team members call to him for help, while at the same time, he sees some Microbots being sucked into a portal, giving him a new idea. Hiro then uses the words of wisdom from Tadashi to successfully guide each of his friends to safety.

After being rescued by Baymax and rejoining the others, Hiro relays his new plan, instructing the team members to take out the Microbots and get them sucked into the portal to eliminate Callaghan's source of power, whilst he and Baymax take on the villain, themselves. Hiro and Baymax fly to attract Callaghan's attention, making him fire towers of Microbots in their direction. Dodging the Microbots, the two fly the point where they are almost sucked into the portal, from where Hiro orders Baymax to dive and break apart the Microbot formations to send them into the portal. Eventually, Callaghan captures the duo and prepares to make the killing strike, only to find that he has run out of the remaining available Microbots, thus rendering him powerless and vulnerable. With this revelation, Hiro and Baymax break free of their confinement and launch towards the villain. Fearfully, Callaghan prepares for his supposedly oncoming demise, but much to his shock, Hiro decides to spare his life, wanting to follow the moral code set by Baymax. Instead, Hiro and Baymax swipe the mask of Yokai and smash it into smithereens, causing Callaghan to finally (and permanently) lose control of the Microbots.

With his plans foiled and power-stripped, the team apprehends Callaghan, but Baymax senses life within the portal, though the being is said to be in hyper-sleep. Hiro realizes that it must be Abigail and the young boy journeys inside to save her, along with Baymax. The two soon find Abigail, asleep in her capsule, and as they make their escape, some of the debris from the destruction of Krei Tech strikes them, causing Baymax to lose most of his armor. Hiro reaches out for Baymax, who manages to grab ahold of his hand, but they both find that the portal is soon closing. Baymax decides to use his rocket-fist to send both Hiro and Abigail to safety, and requests deactivation at Hiro's command. Realizing that this will result in the robot's permanent imprisonment within the portal, Hiro denies such a plan, not wanting to lose him. Baymax disregards his own safety to help of Hiro, reassuring his friend that he'll always be with him. Without a choice, Hiro tearfully hugs Baymax as he bids him farewell, telling the robot that he is satisfied with his care. With these words, Baymax sends Hiro and Abigail off, leaving himself trapped in the portal and eventually destroyed. After Hiro and Abigail manage to make it out of the portal, seconds before it explodes, Hiro reunites with the others and reveals Baymax's demise. Soon afterwards, the police and paramedics arrive to care for Abigail and arrest Callaghan.

Baymax ReturnsEdit

Following these events the superhero team disbands after the loss of Baymax, not wanting to lose anyone else, but Hiro has made a tremendous recovery from his depression as he spends his days hanging out with Honey Lemon, Go Go, Wasabi, and Fred. Finally, he joins the San Fransokyo Institute of Technology as an official student. Before he leaves for his first day, he watches a video of Tadashi helping him ride a bicycle all by himself, and pauses the video to woefully look at Tadashi. He then goes to have breakfast with his friends while the report of the "mysterious" new superheroes is shown. Cass then gives Hiro his lunch and hugs him before letting him go to school.

When he arrives, his friends show him around, but Hiro stops in front of Tadashi's old lab. Wasabi then joins his side by telling him that they all miss him. Hiro then enters the lab and looks at Tadashi's stuff, where the young genius saw Tadashi's cap and Baymax's last piece of armor: his rocket fist, reminiscing of their time together fondly as he comes across it. Within the grasp of the fist, however, Hiro discovers Baymax's original programming chip which contains both his personality and memories. He then sees a notebook with Baymax's blueprints sketched in it, so Hiro eagerly realizes he can rebuild Baymax and quickly gets into doing this. Soon, Professor Granville, the new dean of the SFIT, enters the lab and tells Hiro he is not allowed to work inside it as he first has to earn the lab through hard work, as his brother once did. Granville tells Hiro he can begin by getting to class and that his thermodynamics teacher can be harsh at times, so Hiro rushes to the classroom only to see that Granville herself is the teacher.

For the following days, Hiro focuses on his classes while at the same time works on Baymax. Meanwhile, Fred attempts to convince the rest of the gang into continue their lives as superheroes, but they constantly refuse to it.

Baymax's consciousness is uploaded to a computer while exo-skeleton is finished. Baymax advices Hiro to run some tests before activating it, but the boy is too confident and turns it on ignoring Baymax's advice. Baymax's body then starts acting erratically and jumps out of the window, escaping to the town. Granville then calls Hiro to show him his SFPD report involving bot-fights, but instead of nagging him, compliments that he is being more disciplined than she expected. Hiro however leaves nervously to follow Baymax's body, which he finds has unfortunately fallen in hands of Mr. Yama and his thugs.

Yama quickly reminds him of the night he was imprisoned thanks to Hiro, and gets his men to take him to a high building and drop him off from it. Just then, Yama notices Hiro's SFIT ID, so he tells his men to stop, and instead makes a deal with Hiro to retrieve an item from the institution.

Hiro calls Fred to help, and although Fred tells him that stealing is wrong, Hiro tells him that he would later steal the item back from Yama and return it, therefore "cancelling" the first steal. Hiro then hugs Granville while fake-crying to get close enough to her ID and duplicate it, and when she leaves her office, he goes inside and takes the item, which was used as a paperweight by Granville.

Hiro and Fred then go to Good Luck Alley, meeting Yama at his office to get back Baymax's body. Yama however proves to be treacherous and instead locks up Hiro and Fred, keeping both the paperweight and Baymax. On the other hand, Wasabi, Honey and Go Go went to ask Hiro if he wanted to eat at Noodle Burger with them; instead finding Baymax's computer interface which told them Hiro and Fred had gone to Good Luck Alley.

They then gear up and break into Yama's place, saving their friends to then be taken away by Heathcliff. Regardless, Yama reveals he managed to create an army of Baymax Clones during the time he kept Baymax.

Back at the SFIT the team get upset at Hiro, but he calms them down when he shows he recovered the paperweight, then puts it back to its original place. Honey Lemon also helps to fix the window that Baymax's body destroyed. The following day, Baymax activates the fully finished Baymax, so the two rejoice in their reunion with a loving embrace, and Hiro's next step is to create a new chip that would give back his fighting abilities, but would prevent another incident of Baymax turning murderous.

Before getting started, Hiro takes Baymax to Lucky Cat Café and Cass hugs Baymax, glad that he is back. Later, Fred joins Hiro when he is creating the Superhero Chip, as Fred and Hiro are the only ones who did want to continue being superheroes. Fred suggests their team be called Big Hero 6, claiming that it was the best name he could come up with and that "everyone loved it". Granville then passes by and enters the lab, finding Hiro and Fred while they hid from her, so Granville lectures Hiro into "balance" and that one wrong decision can cause a mess, telling him that he must choose whether to follow Tadashi's lead or to be like Fred.

Hiro comprehends what Granville means and decides to listen to her, then starts ignoring Fred when he tries to convince him to be a superhero. Fred then becomes sad that he is a "lone guardian of justice", but thinks that his friends might be right and the city doesn't have any other supervillains to stop. Right then though, Yama's army of Baymaxes begin attacking the city while Yama and a handful of clones go to the SFIT to personally get the paperweight.

At Lucky Cat Café, Hiro and his friends are watching the attack. Once they saw that the robots were too much for the police to handle, they suited up once more and set out to stop the robots. Yet, Hiro also went to the SFIT to build a new armor for Baymax. There they saw Yama and a clone of Baymax attacked the real one, ripping his vinyl body and leaving his exo-skeleton exposed. Despite this Hiro doesn't worry and instead makes Baymax blend in with the clones to get the paperweight first.

Though Baymax obtains the item, Yama accidentally activates Baymax's healthcare programming, revealing that Hiro was also there. Hiro however uses Baymax's rocket fist against Yama and the mysterious item breaks, which them beings emitting a light and destroys a Baymax clone with its energy. Yama then goes away while Hiro saves Baymax from falling down a window, and the rest of Big Hero 6 join them after they defeated the rest of the robots.

Hiro then has time to gear up, looking at Tadashi's cap and telling to himself that he is "gonna make this right". When the heroes reassemble, Baymax scans for Yama and finds he is near the train station. The item then burns through Yama's pocket and sticks to the incoming train which Cass was inside of. Big Hero 6 then stop the overcharged train, while Hiro and Baymax grab the item, and Hiro destroys it using his magnet gloves. Back to the ground, the team realize how many lives they saved and see that Fred was right. From that moment, they officially become the Big Hero 6, dedicating themselves to protect the city from any and all problems, thus Hiro finally puts his incredible potential to great use as Tadashi had always wanted.

At another place, Obake, the man who had employed Yama to get the paperweight, watches surveillance cameras that show the new superhero team after they foiled the first part of his plan.

Season 1Edit

During the first season of Big Hero 6: The Series, Hiro balances his life as a superhero with his civilian life.

He is introduced to Karmi by Professor Granville, who intended to make Karmi become more social, albeit disguising this as "help" for Hiro. At the same time, Hiro thinks Karmi may have discovered his secret identity when she is drawing him in his superhero suit, but then Karmi is shown naive of this as she believes they are different people. Big Hero 6 fight the supervillain duo High Voltage, subsequently arresting them. They also see the origin of Globby, one of the villains who would cause the most trouble for the team, as well as other evil characters such as Baron Von Steamer, Momakase and Ned Ludd.

By "Failure Mode", Obake continues setting his plan in motion as he allies with Globby to steal a piece of artwork, succeeding in this. Big Hero 6 underestimate Globby as they call him a "sub-par villain", so he is able to defeat them with abilities that none of them knew he had.

For Hiro however, it is becoming harder to be a superhero due to his aunt Cass being close to discovering him in different occasions, so he tries to get her a date. Cass however takes an interest in Alistair Krei, which makes Hiro frustrated and upset. It is also revealed that Krei learned Big Hero 6's identities and blackmailed them to fix his Buddy Guard robots. While the team get to work on it, Hiro tries to ruin Cass and Krei's date, but Mel Meyer gets in the way when he disguises himself as Krei to get back his technology from Krei, so Hiro has to ally with Krei to stop Mel. In the end, Hiro decides to not meddle with Cass' romantic life, though she also decided not to date anyone anymore.

Obake then hires the Mad Jacks to fight Big Hero 6 and make Krei paranoid and have him install a chip which he sold to Krei with lies in order to obtain files from Krei Tech.

Hiro becomes ill and he is also injured when he tried facing the Jacks alone by himself so he is forced to stay in bed while the rest of the team chased the Mad Jacks. Hiro's great intelligence still made him able to fight alongside the team by inventing a Robot Hiro to replace him in battle.

Though the Jacks are defeated, Obake succeeds in his scheme as he makes Krei does install his chip and hacks into his system. The files from Krei also contained information about Hiro, so Obake managed to learn his identity.

Subsequently, Obake reprograms Noodle Burger Boy to discover the alter-egos of the rest of the team. Hiro also comes into conflict to Wasabi and his neat ways of working, but manage to work it out and become closer friends in the end. Unaware of Obake's ongoing scheme, the team continue to face other menaces: Mr. Sparkles becomes jealous of Mochi and threatens to hurt the cat, so Hiro creates a robot named Skymax to save him, and Yama also comes back with a new robot called Mega Yama. Hiro then meets Trevor Trengrove and Wendy Wower, two of Granville's former students who, much to Hiro's surprise, reveal that Granville has been a teacher for longer than Hiro had thought.

Obake soon begins to test Hiro's intelligence, beginning by sending out Globby to make him feel useless, so Hiro decides to upgrade himself with super-strength to be less dependent of Baymax. Fred inadvertently causes a new danger to the city when he orders a gigantic robot Kentucky Kaiju and Noodle Burger Boy hacks into it, causing it to attack the city. With the advice of Mr. Frederickson, Hiro realizes he does not need to enhance himself and only needs to find his true inner strength, then uses his intelligence to stop the kaiju. Upon its destruction, Hiro finds a CPU Robot and starts to discern that someone else must be behind Globby and Noodle Burger Boy's attacks.

Big Hero 6 then come face-to-face with Obake in "Rivalry Weak" when Big Hero 6 help retrieve an important book which Obake stole from Honey Lemon. They meet him at a warehouse, but Obake remains unconcerned and traps them to further test their abilities and intelligence. When the team "pass" Obake's test, he returns the book and disappears.

Karmi's obsession with Big Hero 6, who she still is unaware are her classmates, grows and she starts making fan-fiction making Hiro (who she dubbed Captain Cutie) her lover. Obake also frees Momakase from prison following her previous encounter with the heroes and shows her his entire research on Big Hero 6, so she joins forces with Obake as well to get revenge on them. Hiro is annoyed by Karmi's stories, but cannot say a word as he would reveal his secret. On the other hand, Momakase kidnaps Karmi as she believes that Karmi is Hiro's actual girlfriend after having read her fan-fictions. Karmi is taken to Akuma Island, the very place Big Hero 6 first encountered Callaghan, as it was about to be demolished. When Hiro and the team get out, Karmi hugs Hiro and thanks him, so Hiro decides not to be mean and allows her to continue writing her stories since they had also helped the team in escaping and inspired them to obtain new abilities such as Baymax's Overdrive Mode. Regardless, Hiro is still uneasy about being depicted as Karmi's lover.

Globby also returns to the streets as a criminal, but Big Hero 6 is busy at class so Fred is the only one available to attempt stopping him. Instead, Fred causes a mess while chasing Globby, so Hiro comes up with Mini-Max: a robot resembling Baymax that would watch over Fred. Fred thinks of Mini-Max as his companion, and together they face Globby again. However, since Granville forbid Hiro from using the SFIT's lab after hours to program Mini-Max's chip, Hiro becomes suspecting of her and follows her to Good Luck Alley, narrowly escaping from Yama who he unexpectedly met.

Hiro's distrust to Granville becomes bigger due to her visit to the dangerous place, so he goes to visit the imprisoned Robert Callaghan to ask him about Granville. Callaghan tells Hiro that in the past, there was an incident involved Granville that made her quit her job. Hiro thanks Callaghan and immediately walks away, but Callaghan stops the boy to thank him about having saved Abigail, and says he is sorry about what happened to Tadashi. Hiro becomes sorrowful to hear him say this, and tells Callaghan that forgiving him would be what Tadashi wanted—hoping that, someday, he will be able to.

He then goes to the SFIT to keep spying on Granville, but is caught by her and the new Security System Robots. Granville shows Hiro the robots' CPU and tells him she had created them due to the rising wave of crime in San Fransokyo. Out of sudden, the robots turn against Hiro and Granville, so they go hide while help arrives. While waiting, Hiro questions Granville about her past and why she lied about being a recent SFIT teacher, so she reveals that the last time she allowed a student to use the lab after hours, he started a dangerous experiment and Granville felt guilty from it, leaving the SFIT due to it. Fred and Mini-Max get to the SFIT to beat the robots, because everyone else reasoned that Granville would easily discover their identities. Afterwards, Hiro talks with Granville and promises he would not end up like her student. Unknown to both, it was Obake who had hacked the Security System, and was listening to Granville and Hiro talk about "the student"—who turned out was him.

While Obake continues his plan in silence, Fred reveals his identity to his rival Richardson Mole, who figures out the rest of Big Hero 6's identities and threatens to reveal it to everyone unless he can join the team as well. Hiro agrees with no other choice and gives him a super-suit that was similar to Fred's, then the brand-new Big Hero 7 set off to stop High Voltage once more. After defeating the villains, Richardson Mole is electrocuted and causes memory loss on him, thus he stops being a menace to Big Hero 6 as he forgets their identities.

In "Big Problem", a bio-tech genius called Liv Amara visits SFIT to meet Hiro and Baymax, although Liv loses interest in both far too quickly when Hiro reveals he hadn't created Baymax. Instead, Liv befriends Karmi, causing Hiro to become jealous of her. Big Hero 6 also face Orso Knox, a man who mysteriously mutated into a beast, and after Karmi helps to incapacitate the monster Liv offers to try finding a cure for Knox at her company.

Hiro then becomes more intrigued in Obake's plan, but Wasabi's birthday was coming up so the team decide to recover his car from the bottom of the bay. At the same time, Baron Von Steamer returns to take revenge against Fred's father—formerly a superhero called Boss Awesome. In this occasion, Obake hacks Big Hero 6's communicators to help them into stopping Steamer because Steamer's plan would interfere with his own, and so the team incarcerate Von Steamer while at the same time they ponder why Obake would aid them.

In "The Bot-Fighter", Hiro's old ambitions would return when several heists involving battle bots were happening in San Fransokyo and some of Hiro's former bot-fighter friends were being framed for the crimes. Hiro thinks he should go undercover at bot fights to inquire about this, but during his visit at a competition, he meets Trina and Hiro is falling in love for her. Hiro is being dragged back to the illegal bot-fights thanks to Trina, even being arrested once more. When Cass shows concern about this and grounds Hiro, he decides to go back only once more and search for evidence at Yama's office, who they believed was responsible.

Upon finding out that Trina was actually behind the attacks, Hiro attempts to convince her from getting out of it and go with him instead. Nevertheless, Trina refuses and activates a robot that attacks Big Hero 6 while she escapes. With Megabot's help, Hiro destroys Trina's bot and thanks his friends for having helped him, claiming that if it wasn't for them and Tadashi he might have ended up like Trina. It is then revealed that Trina is an android controlled by Obake, who used her to attempt having the boy join him. Seeing how important Tadashi was to Hiro, Obake's next step is to try manipulating Hiro with the memory of his deceased brother.

Obake implants digital imaging contact lenses into the human members of Big Hero 6 when they go to a haunted house attraction, causing Go Go, Wasabi, Fred and Honey Lemon to see their biggest fears, while Hiro began seeing Tadashi alive and walking around town. He is distracted by this while fighting Noodle Burger Boy and thereby allowing the robot to escape. When Noodle Burger Boy damages Baymax, Hiro starts repairing him at his garage but sees Tadashi again, thus follows him back to the haunted house which he visited earlier with his friends. In the house, Hiro and Tadashi start talking about what has happened since Tadashi's death, and then he tells Hiro to stop holding his genius back and to not fix Baymax anymore. Hiro however proves to be too smart as he knows that isn't something Tadashi would say, so he removes the lenses from his eyes and sees that Tadashi was never there.

The rest of the team are affected by the lenses as well, and become too distracted by their fears that Noodle Burger Boy steals an Hyperconducting Magnet from the SFIT for Obake without them intervening. Hiro is discouraged by this, but wonders how Obake could know so much about Tadashi. It is shown that Obake had also stolen some of Tadashi's test videos from when he was building Baymax, and with the hyperconducting magnet in his hands, he was closer to the final step of his plan.

Countdown to CatastropheEdit

Six months after Hiro joins the SFIT, his first semester is coming to an end and has to come up with a final project to be approved by Granville and shown at the SFIT Open House Expo. Yet, Hiro forgets about it and fights Globby at a warehouse when the villain attempted to steal a Krei Tech briefcase containing an unknown item. Baymax reminds Hiro that he has to show his project, so Hiro hurries to beat Globby and take the briefcase. When he gets to class, Granville notices he is late even though Honey Lemon tried stalling while he arrived.

Hiro tells the professor that he's got nothing, but will have something to propose by the deadline. He then goes to Krei Tech to return the briefcase, which Alistair Krei shows had a failed attempt of an energy amplifier, which he dismissed as "expensive garbage". Hearing that it was an "impossible" technology, Hiro decides to take the destroyed amplifier to attempt creating one as his project. When he is back to his lab to begin work though, Granville immediately denies it, showing some concern for it. Still, Hiro continues to build the energy amplifier at the garage so he can show Granville that she is wrong. Baymax warns him about the impossibility of it, and that he had high chances of being harmed in the process, but Hiro didn't mind and instead told him that "nothing is impossible".

He becomes far too focused into building the amplifier, that he was distracted from a fight against Globby, Noodle Burger Boy and Buddy Guards. During this fight, Baymax was hacked by Noodle Burger Boy with an Obake Chip but he comes later to KreiTech. Meanwhile, Obake reveals that everything so far was part of his plan and intended Hiro to build the amplifier; it is also revealed that Granville's paperweight, the first item he tried to obtain for his plan, was his original amplifier. Hiro then finishes his own energy amplifier and begins testing it on his cellphone and a vending machine, but they explode from the excess of energy it produces. Fred then shows him a Kentucky Kaiju 2.0 which is capable of taking the energy amplifier's power, so Hiro leaves it at SFIT after proving it successful and he can't wait to see the look on Professor Granville's face.

The day of the presentation however, Baymax's new programming warns him about Obake being nearby and convinces him to go fight him instead of going to the expo, telling him that Tadashi would have wanted that. While they arrived to the presumed location, they instead find a Robot Obake which was created to distract them while Globby, Momakase, Noodle Burger Boy and the real Obake invade the SFIT to steal the amplifier. The duo arrive to Hiro's SFIT lab and Hiro commands Baymax to use his rocket fist, but it instead destroys the window despite Obake being right in front of them. The villain then makes his escape using a set of Buddy Guards. Granville also enters the lab and reveals that she knows Big Hero 6 are her students, telling them to take off their helmets assuring that their secret is safe. Granville then shows her file about Bob Aken, her former student who grew up to be Obake, and tells them how Aken had also attempted to create an amplifier but failed, sending him to the hospital while Granville kept the only piece of the amplifier as her paperweight.

Hiro and Baymax then return to their house, where Cass was worried about both due to the SFIT attack. Hiro is also shown to be hurt, but Baymax doesn't activate his healthcare function so he tries to check out his chip port, finally seeing Obake's Chip. When he tries to remove the chip, Baymax's eyes glow red and he grabs Hiro's hand to take him to Obake's lair. On the way to the villain's lair, Hiro tried to remove the chip again when Baymax didn't listen to him. After Hiro and the reprogrammed Baymax arrived at Obake's lair, Hiro tried to free his hand from the reprogrammed Baymax but he told Hiro that resisting will result in further injury.

When Hiro and the reprogrammed Baymax are walking inside of Obake's lair, he sees Momakase slicing sushi, Globby and Noodle Burger Boy playing cards, and he surprisingly sees Trina's head detached from her body, scared by this while Trina mocks him for never realizing she was a robot. Finally, they go to Obake, who welcomes Hiro and he shows a video of Noodle Burger Boy secretly inserting the Obake chip into Baymax's access port because Hiro did not go to the fight with Baymax and he explains that after having researched so much about Big Hero 6 and he had found that he and Hiro are geniuses and he wanted to have him as his student and Hiro will be safe with Obake; also explaining his plan to wipe out San Fransokyo and later the world to Hiro because Obake wants to remake the city and the world with Hiro.

Baymax then throws Hiro into a cell after refusing to work alongside the villain and Obake carries on with his scheme but Hiro is freed by Globby because he believed Obake was crazy but he thought it was fun crazy, and he didn't want to destroy the city. They escape Obake's lair via underwater after Globby faces Momakase, right after Globby globbed her to the wall with the help of Hiro tripping her. Before leaving, Hiro sees Baymax sleeping but Globby drags him away from the sleeping Baymax after he told Hiro that Baymax is a bad robot now. Hiro promises he will return for Baymax, and both go back to Hiro's house. While Globby waits outside, Hiro reunites with Aunt Cass to let her know that he is fine, and he goes to the garage to put on his armor, then contacts his team to tell them that he escaped with the help from Globby and also he tells his team that Obake used Baymax to capture him and bring him to Obake's lair.

Hiro then uses his Skymax to fly to the lighthouse where Obake's machine was built so he can remove his energy amplifier, thus stopping the machine from powering up. Although Hiro retrieves his energy amplifier and reunites with Globby and the rest of Big Hero 6, all see that the machine had reached enough power to activate itself. Hiro tells Honey Lemon and Globby that they will need to create a breaker to protect Fishtown, and tells Go Go and Wasabi to keep people away from the shoreline. Hiro then thinks that the only possible way to stop it is using an opposite equal force, so he makes Fred get his Kentucky Kaiju to use against the shockwave created by the machine. Hiro and Fred are soon joined by Mini-Max, and the trio manage to stop the attack by jumping all the way to space and back, stopping the shockwave from the generated star while the other heroes evacuated the area.

Obake sees his plan has failed thanks to Hiro and feels hopeless now, so the last thing he does is remove his chip from Baymax's access port, allowing Baymax to go back to Hiro while he remained inside his lair but Baymax wouldn't leave until Obake will say that he is satisfied with his care, despite Baymax warning him that the structure was crumbling. Obake tells Baymax the phrase, so the robot leaves reluctantly as he sees Obake apparently crushed by rubble. Baymax then arrives at the shore and saves Hiro, Mini-Max and Fred when they were trapped inside the destroyed Kentucky Kaiju, and all four finally return to Wasabi, Honey, Go Go and Globby. Hiro apologizes for his behavior, but is comforted by his friends by telling him that he also saved the city, then everyone shares a group hug.

Hiro then goes to Granville's office, claiming he has learned his lesson and he thanks her for teaching him about limits and he gave her the amplifier to keep in her vault. Granville still gives him an "A" for his project, but asks him if he knew what happened to Obake.

Hiro and Baymax then get their submarine armors and return to the lair's remains trying to find Obake's deceased body, but Baymax is unable to detect it at all. Hiro reasons that Obake might be still alive yet claims it's impossible he could survive the crash, then Baymax tells him that, like Hiro himself had said, "nothing is impossible".

RelationshipsEdit

Tadashi HamadaEdit

Tadashi is Hiro's older brother and was the most important person in Hiro's life, even after his death. Because their parents died when he was at a young age, Hiro has always looked to his older brother for guidance and advice. They were best friends and even had a set of rules they came up with that only they knew (according to the book, Hiro and Tadashi). They've shared a bedroom since they moved into their Aunt Cass's cafe but don't seem to mind and enjoy each other's company. Tadashi has always been there for Hiro whenever he needed him and the two balance each other well, as Hiro is more creative with his inventions while Tadashi is more practical and by the book, as shown in Hiro and Tadashi. Tadashi sees the potential in Hiro and feels it is wasted when, after Hiro graduates from high school, he chooses to engage in a career in bot-fighting rather than continue his education and use his knowledge to improve the lives of others. Because Hiro is cut off from other people and because Tadashi has been with Hiro since the moment he was born and practically raised him, Tadashi understands Hiro the best out of everyone and was even the one to interest Hiro in robotics. He is also more able to persuade Hiro to do things, as shown when he manages to persuade Hiro to apply to San Fransokyo Institute of technology. He is kind and caring towards Hiro, but is also capable of being stern, demonstrated when he lectured Hiro about how he would get into trouble eventually for his bot fighting obsession and wanted him to stop. He was also goofy, as shown when he grabbed Hiro upside down to shake some ideas into his head. Nonetheless, he was encouraging of Hiro's intelligence and the pursuit of robotics and was always there to protect him, as shown when he saved Hiro from Mr. Yama and his henchmen.

Tadashi's death had the greatest impact on Hiro, who fell into depression and refused to leave his room or eat after the incident. He also refused to attend the San Fransokyo Institute of Technology, despite his initial excitement to join. The death of his older brother also hardened Hiro's heart, and led him down a path of murderous vengeance, as seen when the boy manipulated Baymax's programming in hopes of killing Yokai, only to be stopped by his own friends.

When he tried to pursue the path of vengeance again, Baymax refused, as the latter knew this would not help Hiro and wouldn't be what Tadashi wanted. Hiro then watches clips of Tadashi building Baymax on the robot's video monitor and realizes Tadashi's goal was to help people and that he should do the same. This inspires Hiro to seek justice rather than revenge on Callaghan, makes up with his friends, and continues to do good for the world by becoming a hero.

Aunt CassEdit

Cass is Hiro's aunt. Hiro tends to stress her out and cause her to 'stress eat.' due to his illegal bot fighting but she loves him nonetheless and vice versa. She is very supportive and proud of his abilities and was overjoyed when his Microbot exhibition won him an invitation to attend San Fransokyo Institute of Technology. Like Hiro, she also mourned the passing of Tadashi. She would bring food to Hiro after Tadashi's death as Hiro fell into a severe depression and wouldn't leave his room for two weeks. She tried to encourage him to go to college because Tadashi would've wanted it and she wanted him to recover, but he remained silent and she decided to give him space. When Hiro left his room for the first time in two weeks and he lied about going to register for classes (he was really going to catch up to Baymax), she was overjoyed and hugged him. Overall, the two have a positive relationship and are close, especially since now they are the only known close relatives each has. However, it is interesting to note that Hiro did not want to tell her about Baymax and that he seems to be keeping his superhero persona a secret from her. This is most likely because she has been shown to worry about Hiro and disapproves of him doing dangerous activities (such as bot fighting) and after Tadashi's death, she might forbid him to continue being a superhero as it would put him at risk.

BaymaxEdit

Their relationship started out basic. Hiro was impressed with Baymax when first introduced, but when they reunited, he was less than thrilled as Baymax served as a reminder of Tadashi's death. However, because Hiro unintentionally summoned Baymax when the former expressed pain, the robot viewed Hiro as his patient, becoming solely devoted to him and unable to dismiss himself until the boy was satisfied with his care, vocally expressing that fact. This led Baymax to carry out every small order given by Hiro, no matter how literal or sarcastic, in hopes of improving the boy's health, as a result of his programming.

As time went on, however, Baymax's treatment towards Hiro began to change. As the robot began learning and understanding the basics of human emotion, a personal bond with Hiro began to form. His dedication towards his "patient" was no longer due to programming alone, but also because of a mutual love. In turn, Hiro grew to care for Baymax, who served as his ultimate form of comfort, a loving reminder of Tadashi and a nurturing companion. This is powerfully showcased when the duo found themselves trapped within Yokai's portal while trying to save Abigail. While Baymax was willing to sacrifice himself, Hiro strongly refused, as he didn't have the strength to lose him too. Nevertheless, he fought through his emotions using Baymax's lesson of overcoming loss, but not forgetting, allowing him to bid farewell to his companion, in addition to expressing his love for the first time through a hug.

Following these events and Baymax's eventual revival, the duo remains as close as ever, forming a brotherly relationship and spending their days beside one another through all events, including their mission to protect the world in Tadashi's honor.

Honey Lemon, Go Go, Wasabi and FredEdit

Hiro was first introduced to the rest of his team when he was tricked by Tadashi into visiting his college. He got to meet each of Tadashi's best friends and understand their individual quirks. He was impressed with all their inventions and was surprised by Fred with his mascot costume. Hiro then proclaimed his desire to apply at the institute and immediately began working to develop Microbots. During the time of and before the convention, he had become good friends with everyone.

After the death of Tadashi, the team members took Hiro under their wings, comforting him, supporting him, taking care of him and protecting him throughout the film in place of Tadashi, creating a close bond. This continued even after Baymax's undesired abandonment near the end of the film, as his friends helped him cope with yet another tragic loss.

Wasabi often watches out for Hiro's health and physical well-being, but his over-neatly attitude also caused both friends to have problems at some point. After working things out, Wasabi and Hiro became closer friends.

Honey Lemon serves as an enthusiastic supporter due to her positive attitude, though she isn't as close to him as everyone else is.

Fred shares his love for being a superhero with Hiro, as both were initially the only ones who did want to continue fighting crime once Baymax was rebuilt. Whenever Hiro does things that the rest of his friends might disapprove of, he goes with Fred as he knows he is the most laid-back and rash of them.

Go Go is arguably the closest to the boy, eventually taking on the role of a protective older sibling figure to him. When she gets upset for Hiro doing dangerous things, she usually punches his shoulder but compliments him if things go right regardless of his actions.

YokaiEdit

Being a world-renowned scientist and personal mentor of Tadashi, Hiro initially looked up to Professor Callaghan, showing great respect and admiration towards him. Impressed by Hiro's knowledge, Callaghan was able to slyly convince the boy genius to give up bot-fighting to join the Institute to "challenge himself." It is possible he did this knowing of Hiro's intelligence and wanted him to apply to the school in hopes of stealing one of his inventions (though this is up for debate). Hiro impressed Callaghan at the convention with his Microbots and Callaghan warned him against accepting Krei's offer, manipulating him to say no. When Callaghan was "trapped" in the burning building, Tadashi went in to save him, losing his life in the process. When Hiro discovered Callaghan had started the fire to steal the Microbots and refused to save Tadashi (showing no concern for Tadashi's life or the fact he tried to save him) Hiro was willing to kill the professor as revenge and was only stopped by his team's intervention. However, after Baymax calms him down, he realized his beloved brother wanted to help people, not hurt them, thus realizing he needed to bring Callaghan to justice without harm.

Hiro soon learned from his teammates that Callaghan has suffered the loss of his daughter Abigail (thanks to Krei's misuse of the portal technology that led to her apparent death) and that Callaghan only stole the microbots as part of his true plan to get revenge on Krei. When Hiro confronted Callaghan once again, he tried to reason with him, admitting that he does feel sorry for him and understands the pain of loss and wanted to give the same support his teammates provided him with. However, a bitter Callaghan, while he did show a hint of regret, refused to back down and battled the boy genius, in hopes of killing him. After destroying the Microbots, thus leaving Callaghan powerless, Hiro made the ultimate decision to spare the former professor's life, having set aside his thirst for vengeance in exchange for the moral codes of Tadashi and Baymax. Not only that, he also made the choice to risk his own life to successfully save Callaghan's daughter, after discovering she was still alive within the portal. Though Callaghan showed no forward gratitude towards the hero, he met his defeat through imprisonment, and presumably permanent separation from his only loved one, finally receiving punishment for all the damage he's done, as well as granting Hiro closure. However, Callaghan's expression at the end implies that he shows remorse for what he had done, ultimately realizing that what Hiro said is right about the consequences of getting revenge.

The emotional core of Big Hero 6 is driven by four key characters, their arcs, and the relationships they share with one another, being Hiro, Tadashi, Baymax, and Callaghan. As such, Callaghan serves as an omen of what Hiro would have become if he allowed his pain to consume him. However, unlike Callaghan, Hiro has friends and family who supported him through the ordeal and reminded him justice, not vengeance, is the answer.

Regardless, when Hiro visits Callaghan in prison and Callaghan finally gets to tell him he is sorry about Tadashi's death, Hiro reveals that he has not forgiven him, but hopes that someday he will be able to.

Alistair KreiEdit

The two had a basic relationship and became good acquaintances by the end of the film. Hiro first met Krei at the convention where he was showing off his Microbots and Krei immediately took an interest, hoping to buy the Microbots. However, Callaghan warned Hiro that Krei was known to cut corners and subtly manipulated Hiro to refuse. Krei was clearly disappointed.

Later when Fred assumes that Krei was Yokai, Hiro dismissed it, saying that he's too high profile, possibly implying that he is highly respectful of Krei's public image. When Hiro went to an abandoned Krei lab to track down Yokai, he initially grew to believe Krei was Yokai but was proven wrong after taking Yokai's mask and learning it was Callaghan. He also learned that Krei's teleportation experiment resulted in an accident that presumably killed Abigail which eventually turned Callaghan into Yokai. Despite finding this out, Hiro didn't seem to hold a grudge against Krei for indirectly creating Yokai as he tried his best to protect him from the masked villain. This could be because he knew it was an accident or because he wanted to stop Yokai's plan for vengeance. Krei was ecstatic when the Big Hero 6 team came to rescue him and even openly stated his love of Baymax, apparently growing a true liking for the team following these events.

When Hiro goes to save Abigail, Krei objects, likely showing concern for the boy's safety. However, Hiro assures him by telling him the same words that Tadashi had told him "Someone has to help." Krei seems to have learned his lesson and even built a showcase hall in Tadashi's honor, possibly as a way to make amends since he indirectly created Yokai and therefore was linked to Tadashi's death. Hiro accepted the honor on behalf of his late brother.

Their relationship became more complicated when Krei learned their true identities and began using Big Hero 6 for his own goals, even getting to threatening them if they didn't help him. Hiro also started disliking Krei more when he went on a date with Aunt Cass, afraid they'd actually fall in love and Krei would become his uncle. Because of this, Hiro tried to ruin their date, but in the end Cass also learned about Krei's selfish attitude and held no interest in him anymore, much to Hiro's relief.

Professor GranvilleEdit

Granville and Hiro started off with a difficult relationship due to Granville trying to correct Hiro's chaotic ways, and turned more complicated when Hiro found out that Granville had lied about being a new teacher when in reality she was an SFIT professor 20 years before.

Things however became easier on them after Granville told Hiro the truth to gain his trust and revealed that she didn't want Hiro to end up like Obake, so Hiro learned invaluable lessons from Granville whilst also seeing that she isn't as strict or bad as he initially believed. In the season one finale episode, she refused Hiro to build an energy amplifier for his final project because she has concerns for energy amplifiers and she didn't want him to end up going to hospital like Bob Aken. She told Hiro that it would be impossible to build an energy amplifier so he wanted to prove her wrong by building it anyway.

KarmiEdit

Hiro's classmate and rival, he was both discouraged and often put out by Karmi's stuck-up attitude. Although both of them are sharing the spotlight as SFIT's youngest student with her held little importance to him, he often tried to get on Karmi's good side in a few episodes, but eventually played along with the civilian rivalry with little care.

Also, he is embarrassed at the fact that though she hates his civilian form, she has a crush on his superhero alter-ego, not being able to distinguish the similarities between the two.

However, their relationship has been shown to hint at friendly feelings, as shown in "Issue 188", where Hiro says that they have a lot in common, and that they could even be friends. Baymax then makes the situation awkward by drawing up a pubertic analysis explaining the connection between them. The hint that the two may not see each other as complete rival is demonstrated again in "Small Hiro One", where Hiro notices that Karmi is locked outside of Trengrove's class, and he apologizes for her misfortune, receiving the first kind gesture from her; a small smile that appears to comfort her. Once again, their relationship appears to ascend in "Fan Friction", where Karmi is kidnapped by Momakase, and he comes to her rescue in his superhero form. The two share a friendly moment later on, where Karmi hugs "Captain Cutie" Hiro out of joy, and he appears to accept the gesture. Hiro became jealous of Karmi when she impressed Liv Armara with her extradermal nanoreceptors because he told Liv that he did not create Baymax but Tadashi did and he also failed to impress Liv with the big thermometer that he build for his bio-tech project and he has been keeping tabs of him and Karmi. According to Hiro, Karmi has negative accomplishments because everything that she does is the worst.

ObakeEdit

Hiro and Obake are very much alike. Both are scientific geniuses ahead of their time with great potential. However, their ambitions to achieve success leads them to pushing the limits. When Obake first heard about Hiro, he began to develop an interest in him. Impressed by his intellect, he wanted Hiro to join his side and make him his student once his plan to rebuild San Fransokyo was complete.

EtymologyEdit

  • Hiro - Hiro has many meanings depending on the kanji characters used, but one of the common ones is "generous" or "abundant." Hiro is also a Japanese masculine name. When written in Japanese, Hiro's name is "ヒロ." The transliteration of the English word "Hero" in Japanese is ヒーロー (Hīrō). According to a birth certificate, Hiro's name in kanji is 浜田 飛呂 (Hamada Hiro); 飛 means 'to fly' while 呂 can mean 'backbone.'

TriviaEdit

  • Dates shown in the film indicate that the events are set in 2031. Because Hiro is stated to be 14, it can be deduced he was born sometime around 2017.
  • Hiro and Tadashi seem to share a few traits in the film, such as the usage of "unbelievable" as an expletive when exasperated as well the tendency to solve problems by looking at things from a different angle.
  • Hiro and Baymax's flight through the city could be looked at as a reference to the first Iron Man film when Tony Stark took his first flight.
  • The 2013 Rotoscopers video and early information regarding the plot depicted Hiro with a slightly different backstory: He was already attending classes with Tadashi and could not fit in with the other students due to his intelligence, a fact that he doesn't seem to mind. The Rotoscopers video also depicted Hiro as part of a "science club research team" lead by Tadashi (most likely consisting of Honey, Go Go, Wasabi and Fred) in which each individual would make different things and would eventually lead up to a competition. Like Tony Stark, Hiro felt pressure over using his intelligence for good or just building battle robots in the basement (garage in the final film).[4]
    • Also, in early stages of the story, Hiro was responsible for the creation of Baymax, as opposed to Tadashi, just like in the comic book.[5]
  • Hiro's surname is Takachiho in Marvel Comics, but in the movie it is changed to Hamada, possibly because Hamada is a more realistic surname than Takachiho.
  • Some early concept art showed Hiro wearing glasses just like his comic counterpart, but the idea was dropped.
  • In the Korean dub he is named Hero Armada, removing his Japanese origin.
  • According to Baymax's first scan, Hiro has a slight allergy to peanuts.
  • Hiro apparently loves Gummy Bears, as he enthusiastically told Baymax to retrieve the said item in a flurry of consistently successful test commands with him.
  • Along with Hiro's gap in his front teeth, he has a slight overbite. In addition, in one scene, Hiro was seen sticking his tongue out to bring a straw up to his mouth before sipping, a habit common among people who sucked their thumbs as children.
