Headcanon #24: Hiro’s slight peanut allergy was discovered one day when he was younger and Tadashi shared a peanut butter cup with him. Every day since, he has hated peanut butter cups and gets nervous around people that are eating them.

Headcanon #23: When he was younger, Hiro used to play soccer at school.

Headcanon #19: Hiro is very used to being physically hit on and beat up due to his botfighting days and being bullied in school.

Headcanon #16:  Hiro hates the Fourth of July all because of the fireworks. The loud booms and flashes of lights terrify him and remind him of the SFIT fire. He also used to be slightly scared of them as a child until Tadashi brought him out of it, so, seeing fireworks reminds him of when he was young and his brother comforting him while he was scared.

Headcanon #15:  Hiro and Tadashi were super into dinosaurs and paleontology at one point in their lives. Like all little kids, they went through the dinosaur phase. Tadashi was the one that was into them first. He loved Jurassic Park and Hiro decided to watch it with him one night, which scared him half to death. After getting over the fear of dinosaurs thanks to Tadashi, Hiro joined in on his brother’s facination with them.

Headcanon #13: When he was young, Halloween was Hiro’s favorite holiday. Once he felt he was “too old to dress up” he got slightly annoyed with Tadashi’s costume ideas since they all involved them both matching.
