#amnesia!hiro

Aunt Cass takes down, with tears in her eyes as she does so, every picture that hung on the wall with Tadashi in it. She permanently locks the screen that separated Hiro’s side of the room from Tadashi’s, and she puts his moped and other larger things of his into storage. All this with help from Tadashi’s friends before Hiro gets home from the hospital after hitting his head ue to the Expo explosion. The moment he’d woken up, and Aunt Cass had tried to tell him that Tadashi was …… well, when she’d tried to tell him that, and Hiro hadn’t reacted, she had decided to go the cowards way out and spare her last boy the pain of remembering the brother he’d lost. Better to think himself an only child all along than for him to know he’d been one for less than a week. 

But Hiro is smart, and he quickly starts picking up on the things that are off. He doesn’t remember large chunks of meeting his friends. He doesn’t remember large chunks of making the microbots. How did he get away from half the botfights he escaped from, because he can’t remember that either. Huge black gaps of nothing are spread all throughout his childhood memories as well. And everyone around him won’t answer his questions when he asks about the worrisome memory loss. 

So he starts trying to figure it out himself. He sneaks around the house in search of old photo albums, and he tries to find the key to the lock that’s keeping him from the other side of his room. 

And one day he does it, he finds the key. Yet still, Hiro doesn’t know why there’s a second bed, or why the shelves are full of books about robotics, or why it all looks so lived in despite Hiro not ever remembering someone living in his room with him. 

He slides the screen shut, resolves to look through that room again later, and goes to look elsewhere for clues. Before he slid the screen shut though, he’d taken something. A small red case the size of a backpack, that looked like a robot he could maybe use for botfighting. or a project at SFIT. He sits the red case down beside his bed, not knowing what’s inside of it, because he cannot remember meeting Baymax at all. 

But when Baymax is activated, Baymax remembers Hiro. And Baymax answers Hiro’s questions honestly. 

ohhhhh dear. this does not seem to be starting out well. I wonder why they had their memories wiped. I wonder why they’re both in that holding cell. Who took them and why? What could have happened, what could have been done to them? They form this strong connection, and promise to keep in touch, but what do their forgotten memories have in store for them that might break this partnership? Might break them? 

So many questions and so little answers! AAAAaaaaa 

Bonus for the sunfire Hiro thing I sent in yesterday: Hiro is also on a related drug that mucks with his short to long term memory conversion so he only has five minutes of memory. After the fiftieth time he asks the SAME QUESTION Tadashi just printed out a thing with all the questions he kept asking and their answers on it. That drug goes through his system faster so he can actually form memories properly by midway through Day Two of being back

Oh god, I am fighting healthcare mode SO VERY HARD right now. Because MEDICATIONS THAT’S MY THING MEDS MEDS YEEEESSS.

Okay, now that that’s out of the way. I wonder if Hiro actually found his way to the Lucky Cat by chance? Or if the drug only affects certain kinds of memory. He might not remember his own name or who Baymax and the others are, but the drug can’t eliminate his muscle memory, so the moment he hits the streets his feet are already carrying him home.

And THAT’S what convinces him that he can trust Tadashi and his friends. Because while he might see these people as strangers, somehow he already knows where this Aunt Cass person keeps the spoons in the kitchen. Or which shelf in the garage lab has the textbook on mechanical engineering. Or exactly how their cat likes to be scratched under the chin.

He learns pretty quickly (based on Tadashi’s exasperation and the print out) that his memories might be messed up, but his muscle memory is helping to keep him calm. Because while his mind might not remember, his body sure does.

Except, there’s no weird magical creatures or whatever.

Instead, a few new previously-harmless chemical compounds start to cause unusual effects on people exposed to them. Only about a quarter of the populace can even be affected, but those that are affected with usually develop sharp teeth and claws, get a point to their ears, and lose their memory. The vast majority of cases shift to a digitigrade stance or become able to comfortably walk and run on all fours. Most develop tails, horns, or wings; some even grow fur, feathers, or scales. The first few months are painful, and the transformees (known as ferals) will often lash out violently.

They become less intelligent and more aggressive, often to the point of feral nonsapience, and after the first few weeks of trying to deal with this wave of lashing-out, pained ferals, the government just drives people out of the worst affected areas, walls them off, and dumps the ferals in there with occasional food drops and some guards to make sure that people who want to pick out a feral who’s mellowed out a little do so legally and aren’t attacked.

Pick out, because legally speaking, ferals are animals.

Oh, and they get superpowers. Usually.

At 8 and 16, respectively, Hiro and Tadashi Hamada are accidentally exposed to the most prolific agent.

Within ten hours, Hiro is already forgetting. Tadashi’s unaffected, and has to watch as Hiro starts to transform.

Hiro’s dumped in the largest feral reserve before his transformation is even complete, as his steadily rising body temperature might be indicative of fire powers.

Tadashi throws himself into his studies, especially robotics and medicine, skips a few grades, and ends up finishing Baymax at 19. He does try to retrieve Hiro, especially after finding out that ferals will lose their violent urges after about the third year, but every time, the guard he’s with will just tranquillize the nearest feral that even vaguely matches the description.

After half an hour of searching, he has to give up, as all the transformees are terrified and have fled, or are trying to shoot or throw stuff at them. He tries again a few months later, and it becomes routine.

Days after he’s had his final grade given to him, he sneaks into a reserve that had gotten a large number of transfers from the large one about six months after Hiro was put in the large one.

By that point, Hiro’s intelligence is back, but the only things he remembers are how to talk, read, do maths, and his name. Also that he thinks his stomach didn’t use to hurt so much and he used to be darker skinned with more energy, but he's not quite sure if that’s just nostalgia or not.

 He’s been teaching other ferals who forgot stuff like reading and writing and who’ve regained the mental facilities to do so. These ferals wear tattered clothes, made from the scraps of clothes they had on and what the nonsapients throw away. They hide away from the weird uniformed people with the sleeping guns who shoot any feral that gets too close, or who matches some arbitrary description. Sometimes it’s winged ones, sometimes it’s feathery ones without wings, sometimes horns, sometimes fur, sometimes certain powers or hair or skin colours, always unclothed. They are believed dead, and so the death toll is vastly inflated and the amount of food needed is underestimated.

He doesn’t recognize Tadashi.

But he knows that someone who knows his name on sight and who snuck into the reserve unarmed, after trying and trying to find ones that look like him for years and being furious with his guard for bringing out the sleeping stick, and who is offering him a warm safe place with a lot of food and clean water, probably can’t be too bad.

Tadashi is caught on the way out by a guard, who’s surprised that he’s holding a feral with no care as to just how close the skinny little ‘savage’ is to his neck. Hiro’s slit pupils and 40 degree body temperature seem to be the only non-standard changes, as far as Tadashi can tell.

Eventually Tadashi’s allowed to leave, although he has to take Hiro to a vet qualified in feral physiology for a check-up, which reveals that no, he’s not supposed to be that skinny, yes, he did pick up parasites, yes, he has eyeshine, yes, his metabolism is much faster than a normal human’s, and yes, he does have other changes-his bones and teeth incorporate something rather like naturally produced steel.

Oh, and he’s got iron-deficiency anaemia.

When Tadashi gets his certificate of ownership of a feral, he’s pretty happy. Okay, his brother’s sick, digitigrade, as comfortable on four limbs as two, has a tapetum lucidium, and is probably not sapient, but hey, he’s back and he still likes cuddles.

Then he sees Hiro reading, and oh.

He’s got all his intelligence back.

Ferals go back to being people after all.

Tadashi isn’t sure whether to be horrified that he is now technically a slave owner, or happy that his brother’s fully back (apart from the memories, but, well, he has a few vague fuzzy ones and the new clear ones to go on! ).

He settles for trying to re-bond with Hiro. They missed a lot of bonding time, after all.

(Bizzare accident? KREI *shakes fist at the sky*

But oh man, you scared me for a sec when you mentioned Hiro had fire powers. I was like ‘OOOOH NO I DON’T LIKE WHERE THIS IS GOING FIRE + BH6 AUs = USUALLY SADNESS’ but then it was okay and so was I :D

Oh God, I mixed this movie up with A Beautiful Mind, those are VERY DIFFERENT MOVIES, VERY DIFFERENT, guys. That would be a VERY DIFFERENT AU, OMG

But now that I actually know what we’re talking about, imagine Hiro giving in to despair and getting his memories of Tadashi erased because he’s fallen into depression after his brother’s death. Only what he doesn’t know is that Tadashi survived the fire, rescued by some shady organization who wanted him for sinister reasons. But to get him to work for them, they had to wipe his memory clean.
