A really cool concept for an SSJ2 Gohan crossover fanfiction would be to put him in the world of Middle - earth from The Lord of the Rings. Gohan's strength and honor would make him a great ally to the Fellowship. He could use his super speed and strength to fight off orcs and other dark creatures. He might also have some interesting interactions with Gandalf, learning from the wizard's wisdom while also sharing his own knowledge of martial arts and ki manipulation.
One idea could be a crossover with the Naruto universe. Gohan as SSJ2 could end up in the Hidden Leaf Village and interact with the ninjas. Maybe he helps in a battle against a powerful enemy using his Saiyan powers.
First, decide on the universe you want to cross Gohan with. Then, think about how Gohan would fit into that world. For example, if it's a modern - day Earth setting, consider how he would hide his powers or use them subtly. Next, come up with a basic plot like Gohan has to stop an evil force in this new world.
You could start by establishing the setting and the situation. Say you choose a crossover with the Avatar: The Last Airbender world. Begin with Gohan SSJ2 sensing an unusual energy in that world and deciding to investigate. This sets the stage for the story to unfold.
One common theme could be the struggle between Gohan's good nature and the newfound dark side. Maybe it involves his relationships being strained as his dark side emerges. For example, his relationship with his family and friends might change as he becomes more aggressive or unpredictable.
It can create new power dynamics. If Gohan has a dark side, it might make him a more unpredictable and potentially dangerous force in the universe. Enemies might see this as an opportunity to manipulate him or use his power for their own gain.
Well, there are some great ones. A lot of fanfiction in this area explores the power of Goku in his SSJ4 form in the context of the Dragon Ball Super universe. Some stories might focus on battles that Goku could have in this form against new and powerful enemies, while others could be about his relationships with other characters while being in this super - powerful state. It really depends on what you're interested in.
One common theme is power exploration. Writers often explore the full extent of Goku's SSJ4 power in Dragon Ball Super scenarios. Another is the idea of new battles. Fans like to imagine Goku in SSJ4 facing off against different villains. Also, friendship and family themes are common, like how Goku's new power affects his relationships with his friends and family.
One interesting story could be about a new villain who forces Goku to reach the SSJ4 form in a completely different way. Maybe he has to combine his Saiyan powers with some ancient energy source on a new planet. Another could be a fanfiction where Vegeta finally masters the SSJ4 form before Goku and has to face a powerful foe alone.
Goku is almost always a main character. His journey to master or use the SSJ4 form in new and exciting ways is a common theme. Vegeta is also often included, especially when it comes to rivalries and his own pursuit of power in the form of SSJ4. Sometimes, other Saiyans like Trunks or Goten might also be featured, especially if the story involves the next generation of Saiyans and their relationship with the SSJ4 transformation.
