Kingdom Hearts III[edit | edit source]
Appearance[edit | edit source]
Baymax is a white, inflatable robot with a metal skeleton on the inside. He has two cameras as small, black eyes, connected by a black line, and an access port on the left side of his chest.
He also is seen usually in his red and purple armor, which features rockets in both his fists and legs, and red wings on his back.
Origin and Development[edit | edit source]
Baymax is a healthcare assistant robot built by Tadashi Hamada in the Disney film Big Hero 6. Initially, as a healthcare assistant, Baymax has the ability to scan people for health-related issues and provide diagnostic and treatment information. After Tadashi is killed in an explosion, Tadashi's brother Hiro takes ownership of Baymax. Baymax inadvertently leads Hiro to the scene of the explosion, where they find who they believe is behind the fire and deaths of both Tadashi and his professor, Robert Callaghan. Hiro then retools Baymax, fitting him with his iconic red and purple armor and, joined with his new friends Go Go, Wasabi, Honey Lemon, and Fred, confronted the masked man who had, through the explosion, taken Hiro's microbots. On an abandoned island, they find the man, who turns out to be Professor Callaghan. Hurt and enraged by the professor's disregard for Tadashi's death, Hiro tells Baymax to kill Callaghan, removing his medical programming; however, the others are able to stop Baymax, with Callaghan escaping.
After helping Hiro overcome his anger and grief, Baymax and the rest of the team race to an event at Krei Tech, where Callaghan attempts to use the microbots to exact his revenge on Alistair Krei, whose teleporting experiment had apparently killed Callaghan's daughter, Abigail. Baymax, however, identifies life in the portal Callaghan had built, and he and Hiro hurry to rescue Abigail. They find her in her pod in hyper-sleep, and attempt to get her out, but debris from the fight damages Baymax's armor. In order to rescue Hiro and Abigail, Baymax decides to launch them using his rocket fist. He calms Hiro down, explaining that he will always be with him, and ignites his rocket fists at Hiro's reluctant deactivation command, allowing himself to be left behind in the portal, which explodes just as Hiro and Abigail make it out.
Sometime later, Hiro finds Baymax's healthcare programming chip in the palm of the rocket fist, and, using Tadashi's plans, recreates Baymax.
Baymax was the first character revealed from Big Hero 6 to be featured in Kingdom Hearts III, seen in early artwork released at D23 2015 for the game.
