Au when both Tadashi and Hiro are different humanoid alien species found and adopted by Mama and Papa Hamada. Hiro has psychic abilities like telekinesis and Tadashi has fire and heat based abilities. However they were raised as humans so their abilities manifest much later.
Tadashi was old enough to know that he and Hiro werenāt quite human, but Hiro was so little he never really noticed that there was anything different between himself and the humans that took him in. Still the Hamada parents made sure to tell Tadashi over and over that they could notĀ tell anyoneĀ about what they were or what they could do. And Tadashi listened
When their parents died and Aunt Cass took them in, Tadashi remembered his adoptive parentsā words, and told her nothing. Hiro had all but forgotten their extraterrestrial origins, so there was no risk of him saying anything, and their powers hadnāt kicked in yet, so Aunt Cass doesnāt know. Tadashi doesnāt even tell the rest of the SFIT crew.
The only other one who knows is Baymax, and thatās because Tadashi scans differently than a human. But Tadashi makes sure to program Baymax to keep his secrets right from the start, so the robot tells no one.
Tadashiās powers manifest in the middle of the fire, allowing him to survive, but he doesnāt know what to do with himself after that. If he reveals that heās alive, people will wonder why heās unharmed, and those questions might dig up answers heās been hiding since he was a child. But Hiro is so upset, and thanks to his secrecy programming, Baymax canāt even tell Hiro that heās alive. All he can manage isĀ āTadashi is hereā
But when Hiro starts manifesting his own powers during the fight with Callaghan at KreiTech, Tadashi knows he canāt stay hidden anymore. Hiro has no idea whatās happening to him, and the only person with the answers he needs is Tadashi. So Tadashi waits until they get home after the fight, and reveals himself.
Hiro does notĀ take the news well. On the one hand, heās furious Tadashi hid from them for so long. On the other hand, heās already felt like a freak all his life, now he knows he really is one? And what will his new friends think of him?
Tadashi winces, because honestly heās a bit worried about that too.
But to the brothersā shock, their friends are honestly offended that they thought that theyād turn on the Hamadas just because theyāre a little weird. I mean really, they hang out with Fred.
GoGo punches them on the shoulder, Honey Lemon tuts fretfully, Wasabi rolls his eyes, and Fred just complains that they kept such an awesome secret from him for so long. They donāt care one bit.
Meanwhile Baymax is standing nearby feeling very happy because his patients are all here together and safe and he doesnāt have to protect any more secrets
