GoGo: Honey, you shrunk Hiro...

Honey Lemon: Oops...

Yep. Hiro is really... small.

Tiny magic Hiro sometimes climbs the Nerd Herd members and his family. As in, he makes little ropes from magic and climbs them like mountains. It's adorable.

What wasn’t adorable was the time he thought he’d take it all the way, and give himself tiny picks and spikes like real rock climbers use. Sure, they were really tiny, but to the others it felt like having little needles driven into your skin over and over. Ouch.

Tadashi’s just happy that Hiro started with a harness. As far as he’s concerned, Hiro should be harnessed to all of them whenever he’s riding around on their shoulders or heads or whatever, because a fall from that high for someone that small would not be good. Hiro, on the other hand, thinks he’s being paranoid and therefore delights in doing diving stunts off of Tadashi the most.

AU where Hiro is half a foot shorter and constantly chewing out his aunt and brother since he's still forced to use a car seat.

They’re just worried about his safety, okay? Although part of it is punishment because Hiro, even though he’s even smaller than canon, still sneaks off to go bot fighting.

As Aunt Cass puts it, if he’s going to act like a child, they’re going to treat him like one. It is actually a very effective deterrent and Hiro gives up the bot fighting very early on.

I have a weird mental image of Tiny Hiro trying to sneak out of the cafe. Unfortunately, Tadashi has experience with these things, and easily catches him. Tiny Hiro is confined to sit in a snow globe for twenty minutes, listening to a song that Tadashi has made into Hiro's lullaby.

Hopefully an empty snow globe, otherwise he better have teeny tiny scuba gear with him too.

The ironic thing is that the song is a music box version of California Girls by the Beach Boys because the snow globe came from a tourist shop in San Fransokyo. Hiro hates the song in real life, but for some reason he loves it when he’s in the snow globe. Tadashi has learned not to question these things.

Tiny Hiro's really strong, even taking into account the protection spell and square cube law, because so many things are heavy compared to him. So even lifting a pen is hard. Doesn't stop him from, by 13, casually walking around carrying things up to 40 times his weight. (Square cube law is crazy. And then there's the strength doubling effects of the protection spell. )

Just picture one of GoGo’s wheels slowly travelling across the lab floor towards her, seemingly of its own wheel. But then, when she leans down and takes it, Hiro was underneath the whole time, bringing it to her. That’s his favourite thing to do in the lab; bring stuff for people because it gives him a chance to run around.

It makes Tadashi super nervous to have teeny Hiro wandering around on the lab floor carrying things, because what if someone steps on him? But his clothes are so bright and noticeable, they’re essentially safety vests, so it’s never a problem. Plus all the nerds are well used to watching out for him now, it’s become habit for them

Science fantasy AU where magic is a thing. There’s several types of spells; permanent spells, which remain on the target, affecting it, until cancelled or until they wear off, and instantaneous spells, which, once done, have to be counterspelled. Permanent spells lack proper ontological inertia; removing a permanent shrinking spell will cause the target to grow to their true size in a few seconds. An instantaneous shrinking spell cannot be removed so much as countered (it’s done its effect, it’s finished and gone) and once done, have ontological inertia. Hiro and Tadashi have magic ability and both have minor magic surges.

Magic surges result in wild magic that can do things that human mages then can sometimes take years to develop ways to replicate-most spells were copied from the effects of magic surges.

Hiro’s are stronger overall, but as he has the potential to be a VERY powerful mage, it’s to be expected; they mostly just levitate objects, make random things glow or change colours or stick to each other, and are easy to handle by whoever’s not surging (this includes Aunt Cass). The effects of both boys’ surges are easily reversed, or naturally wear off in a small period of time.

Then they discover the hard way that a then six-year-old Hiro’s peanut allergy includes the bizarre (and reasonably rare) symptom of ‘powerful magic surges’. Opps.

It’s very difficult for Cass and Tadashi to reverse and manage the effects of the surge, and while trying to corral an animated table that had sprouted claws and was taking swipes at Mochi and the walls, they fail to notice that Hiro’s shrinking.

He stops at the size of a large mouse, and it’s an instantaneous spell.

The first day’s the hardest; they have to adjust, and quickly.

By the second day, Hiro’s got a warming spell on him, keeping him at a comfortable temperature, and a simple weak protection spell that made him slightly tougher and stronger.

By day five, a professional mage had boosted the protection spell until Hiro was twice as strong, and tough enough to survive being stepped on. (A Lucky Cat customer with poor eyesight thought he was a mouse and tried to squish him. )

Aunt Cass starts homeschooling him, and getting in tutors to help; meanwhile Tadashi sews Hiro brightly coloured clothes so that Hiro doesn’t get mistaken for a mouse again (splinting a broken arm the width of a toothpick is HARD).

When Tadashi graduates, Hiro insists on going to SFIT with him-as in, riding in his pocket. 

Not having been bullied as much as canon Hiro, this Hiro is much less nervous and insecure, and so doesn’t fake confidence.

The first people he has a proper chat to are the Nerd Herd, who he meets because they’re sharing a lab.

(Fred will forever deny squeeing at the sight of a kitten-sized 13-year-old kid sitting on Tadashi’s hand and smiling nervously up at them. )

They quickly become friends.

(Awww, I’m basically picturing the scene in Cinderella where she makes tiny clothes for the mice. Only Cinderella is Tadashi, and the mouse is Hiro. I bet Tadashi goes out to fabric stores with Hiro in his pocket, and they pick out the craziest, brightest, funnest bits of fabric from the scrap bin for super cheap, and take it home and just go NUTS with it. Hiro probably has a lot of really wacky ponchos from when Tadashi was just starting out and learning to sew

If he ever grows back to normal size, he will definitely end up still wearing wacky coloured things. Because that’s what he’s used to.)

Borrower Hiro would have a slightly unnerving metabolism. Like, he's ALWAYS up for food, because he's SO SMALL that to keep warm he needs ALL THE FOOD. He'd probably have to go torpid at night. He spends a LOT of time snuggled up with literally ANYTHING warm, because he gets hungry really fast otherwise. Really, really, really fast. Did you know a shrew can starve to death in an hour, and a mouse in a few days? Yeah.

Thankfully he’s also teeny enough that you can hand him a cracker and he’s set for DAYS. And that’s exactly what Tadashi does, he just carries around little baggies of crackers and nuts and candies in his pockets so he can give Hiro a snack whenever he gets peckish. The others have the same habit too, but Aunt Cass is Hiro’s favourite because the snacks she carries in her pockets are her own baked goods. Mmmmm, cookie crumbs

And because Hiro gets cold at night, he ends up stealing one of Tadashi’s thickest, warmest socks and using it as a bed. On the really cold nights, Tadashi pulls out a heat lamp for Hiro and sets it up so Hiro doesn’t freeze. But overall Hiro prefers to snuggle with Mochi because Mochi will purr and lick his head and snuggle with him and the two of them keep each other warm and it’s so lovely. And unlike Tadashi, Mochi won’t accidentally roll over and almost crush Hiro in his sleep.

(It happened only once and Tadashi was so freaked out he refused to let Hiro sleep anywhere near his bed ever again. Hiro still insists he’s fine, and he was barely smooshed)

An AU where everything is mostly the same- except Tadashi survives the fire, and Hiro is inexplicably 4 inches tall.

Aaaaah teeny Borrower!Hiro AU!

Maybe that’s why Tadashi survived the fire, because he was carrying Hiro around in his pocket or on his shoulder at the time, and he didn’t dare risk Hiro’s life as well as his own if he’d run in.

Just picture the Team with Tadashi in Hiro’s place stuck to Baymax’s back, but then Hiro’s suck to HIS back with teeny little magnets and teeny little armour of his own. Or maybe with just one big magnet. They bring Hiro along even though he’s so small because they know he’ll sneak into Fred’s suit if they don’t and possibly get stepped on, and because you never know when you need to stick a tiny borrower into a badguy’s complicated doomsday device so he can sabotage it.

AAAAAAH LOVE TEENY HIRO I’M SO HAPPY
