who was the villain in big hero 6
Big Hero 6 (film) The group tracks the masked man, whom they suspect to be Krei, to an abandoned Krei Tech laboratory which was used for teleportation research until a test pilot was lost in an accident. The masked man attacks, but the group subdues him and knocks off his mask â€” revealing him to be Callaghan, who had stolen Hiro's microbots to shield himself from the explosion. Enraged, Hiro removes Baymax's healthcare chip, leaving only the battle chip, and orders him to kill Callaghan. Honey reinstalls the healthcare chip at the last second, preventing Baymax from carrying out the kill order. Callaghan escapes, and Hiro leaves with Baymax, intent on avenging Tadashi.
