What could be an interesting plot for a My Hero Academia x Dragon Ball fanfic?

Perhaps in the fanfic, there could be a villain who is trying to steal the cutie marks of the ponies in the MLP world and use their power for evil in the My Hero Academia world. The heroes from both universes would then have to team up. Deku could use his One For All to protect the ponies, while the ponies could use their friendship magic to support the heroes in combat.

One interesting crossover could be the characters from My Hero Academia having to face the power levels of Dragon Ball characters. For example, Deku might learn from Goku about the concept of constantly pushing one's limits and training harder. Another could be the quirks in My Hero Academia being combined with the ki abilities of Dragon Ball. Maybe Todoroki's ice and fire quirks could be enhanced with the use of ki control.

One idea could be that the Pokemon world has some sort of villainous force that is affecting the balance of power, similar to the villains in My Hero Academia. The heroes from My Hero Academia are transported to the Pokemon world to help. They could team up with Pokemon trainers and use their quirks in combination with Pokemon attacks to fight against the common enemy.

A great plot could be that there is a mystery surrounding the origin of the dragon quirk. Is it related to some ancient power or a genetic experiment? The character sets out on a journey to discover the truth about their quirk. Along the way, they meet other characters with unique quirks and form alliances. They might also encounter villains who want to use their quirk for evil purposes, adding a layer of danger and excitement to the story.

One interesting plot could be that a Prototype character, say Mercer, somehow gets his powers transferred to a My Hero Academia villain. This villain then becomes extremely powerful and starts causing chaos in a way that the heroes can't handle. The heroes have to figure out how to stop a foe that can shape - shift, regenerate, and has superhuman strength. They seek help from the Prototype world, and a character from there has to work with the heroes to find a way to reverse the power transfer or at least find a weakness in the empowered villain.

One possible plot could be that the villains in My Hero Academia somehow get their hands on the Infinity Stones. They could use the power of the stones to start warping reality. For example, they might use the Reality Stone to make the heroes' quirks ineffective or change the very nature of the hero society. The heroes would then have to band together, not just from UA but from all over the world, to try and stop the villains from completely taking over. They would need to figure out how to combat the power of the Infinity Stones, perhaps by finding some sort of counter - quirk or ancient hero relic.

Well, the plot could involve a quirk experiment gone wrong that creates portals between the two universes. The Avengers and the MHA heroes end up on the wrong sides. At first, there's a lot of misunderstanding and fighting between them. But then they realize that there's a bigger threat behind all this chaos. For instance, Loki could be working with a MHA villain to take over both worlds. The Avengers and the MHA heroes then have to put aside their differences and work together to stop this evil plan. The story could explore how different powers interact and how characters from two very different universes grow to respect and rely on each other.

Maybe there's a device that accidentally transports the top heroes from both universes together. In this crossover, All Might and Saitama could have a friendly competition to see who can defeat the most villains in a day. However, they quickly realize that their worlds have different threats and they need to work together. For example, Saitama could learn about the concept of 'quirks' and how it affects hero society, while All Might could be amazed by Saitama's pure physical strength.

Friendship is also a big theme. In both Dragon Ball and My Hero Academia, friendship plays a crucial role. Fanfictions will often show characters from both series forming bonds, working together to overcome challenges, and growing as individuals through those relationships.

One possible plot could be that the heroes from My Hero Academia are transported to the Demon Slayer universe. They team up with the Demon Slayers to fight a new breed of demons that have quirks. Midoriya could learn some sword - fighting skills from Tanjiro and in return, Tanjiro could gain some knowledge about using quirks in combat.
