This page is for Baymax (comics), the character from Marvel comics. For the character from the film, see Baymax.

Baymax is a robotic synthformer created by Hiro Takachiho and is a member of the Japanese superhero team Big Hero 6.


Baymax was initially the science project of super-genius Hiro Takachiho that was intended to be presented at the Tesuka Advanced Science Institute. Though he was made to be Hiro's personal bodyguard, Baymax found a new purpose of filling the void left by the death of Hiro's father, Tomeo Takachiho, when the young inventor installed his father's emotions and memories into Baymax's artificial intelligence. Functioning as Hiro's best friend and father figure, Baymax is by his side nearly every hour of every day.

Baymax is programmed to serve and protect Hiro and therefore unable to allow his creator to be placed in possibly dangerous situations. But within the team, Baymax's phenomenal strength and surveillance and data analysis capabilities have proven useful in coordination.

Powers and abilitiesEdit

Baymax is a hydro-powered synthformer, capable of changing his shape into various battle forms. As his source of power for locomotion, Baymax can fuel himself with water.

  • Shapeshifting: Baymax can change his appearance at will. His default form is a large human robot to pose as Hiro's guardian in order to avoid seeming conspicuous. His other forms include "Battle-Dragon" and "Action-Mecha", the former grants Baymax the appearance of a dragon-like humanoid and the latter has the appearance of a large humanoid robot.
    • Battleform: Baymax's battle forms are significantly more powerful and imposing than his default humanoid form, and are primarily used during undercover missions and other hostile operations. However, should Baymax sustain severe damage in a fight, he will revert to his default form and become temporarily depowered.
  • Superhuman durability: Baymax possesses a durable, polymantium exoskeleton resistant to most small ballistics.
  • Sensors: Baymax is equipped with internal scanners and sensors able to detect and evaluate the threat posed by lifeforms in the immediate vicinity. He can also deploy remote monitors to record events from afar.
  • Flight: Baymax is capable of flight, thanks to jet engines equipped in his feet capable of propelling him at speeds up to Mach 4.
  • Communication: Baymax can send, receive, and intercept radio transmissions, and monitors all networks maintained by the Japanese Ministry of Defense. Baymax is also directly linked to Hiro's personal Core Cyber-Network (CCN). As a result, when Baymax is not in Hiro's vicinity, he can be immediately summoned via a communication device mounted on Hiro's wrist. Baymax is also connected to Hiro's cybernetic glasses, so everything that Hiro sees and hears while wearing his glasses is stored in Baymax's databanks for later reference and analysis.
  • Programmed skills: Baymax possesses certain abilities due to his programming. His artificial intelligence system is from a memory card that contains the thoughts and emotions of Tomeo.
    • Martial Artist: Baymax is programmed with fighting techniques from several forms of combat, including karate, tae kwon do, Western boxing and Wing Chun.


When the Japanese organization known as the Giri recruits Hiro into the fledgling super-team Big Hero Six, Baymax opposes the idea of Hiro being placed in harm's way but soon consents to joining the team along with a reluctant Hiro during the group's battle with Everwraith, who had abducted Hiro's mother. With the team, Baymax fights various supervillains to protect Tokyo, including X the Unknowable and the Crimson Cowl. At one point, someone implants Baymax with a mind-control device, causing him and Big Hero Six to briefly fall victim to mind control. When the mind-control device later short-circuits and frees Big Hero Six from mind control, the team returns to Japan to seek out the parties responsible for their mind-control.

After the superhuman Civil War, Baymax joins the new incarnation of Big Hero 6 with new members Wasabi No-Ginger and Fred. Baymax accompanies the group when the team is assigned to protect Dr. Kojiro Iosama in America, and battles the supervillain Badgal and her brainwashed minions Brute, Gunsmith and Whiplash.
