Less sad Sunfire AU! There was an experiment that the Hamada parents were working on, involving genetic engineering and an odd substance that could be biologically produced and basically did magic. They defected from the project after a while, taking home a modified kid (Tadashi). Then, about eight years later, they adopted Hiro. (He was two. ) Tadashi never gets his tongue scalded from hot soup, but that seems to be the only effect. Then he runs into the fire and isn't burned. (1)
He's found when firefighters search the wreckage, pinned under a beam, bleeding, with broken legs. He's also experimenting with making tiny little sparks come from his fingertips. He's hospitalised for a little while, and by the time he comes home he can make a tiny little flame just big enough to roast one marshmallow. That's how he practices: roasting marshmallows (or just heating things up without fire, which he can also do. )
Thus we discover the best superpower ever. Being able to heat up your tea after you’ve forgotten it on the counter for twenty minutes. *weeps with joy*
But oh man, that would be pretty cool. I imagine Hiro would freak when he finds out though (He may have a slight phobia of fire after the SFIT incident). But then, once he’s calmed down, he’d have all sorts of questions for Tadashi.
“So mom and dad were magic?”
“No, I’m pretty sure they weren’t.”
“Were they secretly mutants?”
“Aw, come on, Tadashi! Was my adoption really a secret alien abduction?”
“Mom and dad weren’t aliens!”
*cue Tadashi chasing Hiro all over the house while Hiro runs away cackling and calling him ET*
