The fanfic could also explore a more romantic plot. Gohan and Supergirl could be brought together by some sort of magical or scientific accident that links their fates. As they spend time together, they discover they have a lot in common, like their love for their families and their determination to do good. Their relationship could develop slowly, with them learning about each other's cultures (Saiyan and Kryptonian) and powers, and eventually falling in love.
First, do your research on both characters. Know Gohan's abilities like his Super Saiyan forms and his martial arts training from the Dragon Ball series. For Supergirl, understand her Kryptonian powers like flight, super strength, and heat vision. Then, come up with a starting point for their story, like a meeting in a neutral dimension.
One possible plot could be that Supergirl and Dreamer, both with their unique powers, team up with a character named Lemon. Maybe they are facing a new villain in National City. Lemon could have some special knowledge or ability that helps Supergirl and Dreamer in their fight. For example, Lemon might be an expert in some ancient technology that the villain is using. They could go through various challenges together, and along the way, they might also develop deeper friendships or even discover new aspects of their own powers.
The plot could start with Naruto being accidentally transported to the world of Supergirl. His godlike powers are a mystery to the people there. Supergirl is initially suspicious of him but soon realizes his good intentions. They then team up to stop a powerful alien threat that neither could face alone. Naruto uses his Rasengan and other jutsu, while Supergirl uses her heat vision and super strength.
Well, one possibility could be that Naruto somehow ends up in the Supergirl's universe. They might start as rivals, with Naruto's ninja skills and Supergirl's superpowers causing some initial clashes. But as they get to know each other better, they could team up against a common enemy. And perhaps, in the process, they develop a deep friendship that might be misconstrued by others in their respective worlds.
The theme of overcoming differences also pops up a lot. They are from different fictional universes, with different power systems, languages, and ways of life. Fanfictions often center around how they bridge these gaps to become allies or more. They might face challenges like misunderstandings at first due to their different ways of communication, but eventually find common ground through shared values like protecting the innocent.
One plot idea could be Gohan getting into trouble at school and Chichi having to deal with it. She might teach him how to handle bullies or study better.
It could be about them teaming up for a new adventure in the Dragon Ball universe. Maybe they discover a new threat and have to combine their powers and skills to defeat it.
If such a fanfic existed, perhaps it could be about Gohan somehow ending up in the Marvel universe and meeting Pepper Potts. They might team up to solve a problem that combines elements of both their worlds. But without the 'lemon' aspect as it might be inappropriate, they could just be friends or colleagues in a strange new situation.
The plot might involve Bulma creating a new device that has some unexpected side effects. Gohan then comes to help her fix it. Along the way, they might encounter some old enemies or new threats. And perhaps through this experience, they develop a deeper understanding and friendship. For example, Bulma could be working on a time - travel device and accidentally sends them both to a different era, where they have to rely on each other to get back home.
A possible plot could be Kara dealing with her pregnancy while still trying to protect the city. She might have to hide her condition from her enemies. For example, she could be worried that her enemies would target her baby or use her pregnancy - related weakness against her.
