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. Baymax could interact with Superman, which would be an interesting contrast of a big, strong hero and a soft, caring robot. Or perhaps a crossover with the Powerpuff Girls. The girls' superpowers combined with the tech - savvy of Big Hero 6 could lead to some really fun and action - packed adventures.
For a Big Hero 6 crossover fanfiction, consider a crossover with Star Wars. The Big Hero 6 crew could find themselves on a planet in the Star Wars universe. Hiro might be fascinated by the droids there and try to incorporate some of their features into Baymax. They could also cross paths with the Jedi and help them in a battle against the Sith. Another idea is a crossover with How to Train Your Dragon. The team could visit Berk and use their technology to enhance the Vikings' dragon - riding capabilities.
A great crossover idea is with the Dragon Ball series. The powerful Saiyans could interact with the My Hero Academia characters. Goku could train the students at UA to reach new levels of power. Also, a crossover with the Attack on Titan world would be intense. The heroes would have to deal with Titans in a whole new way and use their quirks in that battle - filled environment.
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. Or a story that focuses on the friendship between Hiro and Wasabi, showing how they support each other during tough times. Also, a fanfic where the team has to operate in a different city or country, dealing with new cultures and challenges.
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. For example, they might know about an upcoming big threat but their attempts to prevent it might accidentally set off a chain of events that make the situation worse. 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.
One idea could be a crossover with the Naruto universe. The characters from My Hero Academia could interact with Naruto characters. For example, Deku might learn some new fighting techniques from Naruto. Another idea is a crossover with the Harry Potter world. The students at U.A. could visit Hogwarts and experience magic, while the Hogwarts students could learn about quirks.
A cool My Hero Academia crossover fanfiction idea would be with the Avengers. The heroes from UA could team up with the Avengers to fight a common enemy. For example, a powerful villain who can absorb quirks and powers. It would be interesting to see how characters like All Might and Captain America interact, and how their leadership styles differ.
Perhaps an OC who has a special power related to nature in a world full of high - tech. They could struggle to fit in at first but then find ways to combine their natural abilities with the tech - savvy of the Big Hero 6 team. For example, using plants to enhance communication devices or something like that.
One interesting idea could be a crossover with another popular superhero universe, like Marvel or DC. This could lead to epic battles between different types of heroes. Another idea might be a crossover within the My Hero Academia world itself, for example, different classes or generations of heroes teaming up in unexpected ways.
One idea could be a crossover with 'One Piece'. The heroes from 'boku no hero academia' could end up on the Grand Line and have to deal with pirates while also using their quirks. Another is a crossover with 'Naruto'. Maybe the students of UA could train with the ninja in Konoha, learning new skills and sharing their quirk knowledge. A third could be a crossover with 'Attack on Titan', where the heroes have to face the Titans and figure out how to use their quirks to defeat these huge threats.
One idea could be that the heroes from Hero Factory are sent to the Bionicle universe to help fight a common enemy that threatens both worlds. Maybe a new type of robotic - organic hybrid villain that is too powerful for either group alone.
One idea could be a crossover with 'Star Trek'. The characters from 'The Big Bang Theory' could find themselves on the Enterprise, with Sheldon trying to understand the advanced technology there.
