Fanon
Hirozilla is one of the less popular ships in the Big Hero 6 fandom. Many fans see them as a platonic friendship instead of lovers. Even when there are times where Fred serves as Hiro's confidant and guild, for when it comes to the world of superheroes, their code and other pieces of fact that can be a bit childish and nerdy at times.

On AO3, the ship has over 6 pieces of written work.
