There might be a fanfiction where the Big Hero 6 team travels to a parallel universe. In this universe, they are not the heroes they are in their own world. They have to figure out how to get back home while also dealing with the alternate versions of themselves. It could be full of action and self - discovery for each character.
A cool 'Big Hero 6 Fanfiction' could revolve around Tadashi. What if he didn't really die? He could come back in some mysterious way and have to readjust to life with Hiro and the team. There would be a lot of emotional reunions and also some challenges as he tries to catch up with all the changes that have happened since his 'death'.
One interesting 'big hero 6 lemon fanfiction' could be about Hiro and Baymax's adventures in a new, lemon - scented world. Maybe they find a lemon grove that has some sort of magical properties that help them solve a new mystery in San Fransokyo.

Well, you could write a Big Hero Six fanfiction where Baymax develops some new emotions or abilities. Maybe he starts to understand humor in a more complex way.

An interesting OC for Big Hero 6 fanfiction could be a time - traveler. This OC accidentally lands in San Fransokyo during the time of Big Hero 6. They have knowledge of future events which could either be a great help or cause some major problems.

The OC would have to work with the team to fix things while also dealing with the fact that they are out of their own time.
A cool Big Hero 6 crossover fanfiction idea might involve crossing over with the DC Universe. Hiro could meet Batman and learn about his detective skills and use of gadgets.

The girls' superpowers combined with the tech - savvy of Big Hero 6 could lead to some really fun and action - packed adventures.

The story of Hiro's journey to become a hero is really interesting. He starts as a young, smart but aimless boy, and then with Baymax and the team, he grows into a real hero.
