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.
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.
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.
There's a fanfiction where Gohan meets Supergirl during a multiverse crisis. In this story, Gohan is intrigued by Supergirl's strong sense of justice which is similar to his own. They team up to save both their worlds from a powerful villain who is trying to merge the universes for his own evil purposes. The story is full of action scenes and their growing friendship.
I'm not entirely sure if there is a specific 'Gohan x 18' fanfic. While the idea of pairing these two characters is interesting, not all fanfics are easy to find. Some might be on specialized fanfic websites, while others could be hidden in less - known corners of the internet. You could try searching on well - known fanfic platforms like FanFiction.net or Archive of Our Own, but there's no guarantee that you'll find one right away.
I'm not sure specifically about a 'good' Gohan x Lavender fanfic. But often in fanfics, authors take creative liberties. They might give Lavender new traits or backstories to make her more compatible with Gohan. It could be that in some fics, they are brought together by a common goal, like saving a planet or a particular group of people. You really have to explore different fanfic communities to find one that you'll enjoy.
One idea could be that Naruto, with his godlike powers, arrives in the DC universe where he meets Supergirl. They initially clash due to their different ways of handling threats. But as they get to know each other, they start to combine their powers to fight a greater evil that threatens both their worlds.
One popular 'Gohan x Moka' fanfic is 'A New Bond'. It explores an interesting scenario where Gohan and Moka meet in a different dimension and have to team up to face a common enemy. The story does a great job of developing their relationship gradually.

A 'Gohan x Reader Lemon Fanfic' typically involves a romantic and often fictional scenario between Gohan and the reader. However, lemon content usually implies mature or sexual undertones which are not appropriate in all contexts.

It might include elements like the development of feelings between the two characters, shared adventures, and emotional exchanges.
