Another good character could be Bulma. She's a scientist, so she could be interested in the properties of lemons in this crossover world. She might try to create new gadgets or power - ups using lemons. Her presence would also bring a different kind of energy compared to Gohan's more martial - arts - focused personality. She could be the one to figure out how to get Gohan back to his own world if he's stranded in the lemon - crossover world.
Piccolo could be an interesting crossover character. He could be from a world where lemons have some sort of magical or spiritual significance. His relationship with Gohan in the original story would add depth to their interactions in this crossover. For example, Piccolo might be initially skeptical of the lemon - related things but eventually see their value when it comes to helping Gohan.
Definitely Superman. Superman's super strength and Gohan's Saiyan power would make for an interesting combination. They could have a friendly sparring match to test their limits. Another good character could be Ichigo from Bleach. Ichigo's sword - fighting skills combined with Gohan's martial arts and ki blasts would create some epic battle scenes.
Well, in the context of 'Immortal Gohan Crossover Fanfiction', Trunks could be a great crossover character. They could travel to different dimensions together. Android 18 might also be good. Her strength and Gohan's immortality could lead to some unique storylines. Also, Cell, if he was somehow reformed in the crossover, could create a really complex and interesting dynamic with Gohan.
In a crossover with the Dragon Ball universe itself, Broly would be an interesting character to pair with an overpowered Gohan. Their battles would be intense and epic, with both having incredible strength. They could also end up having to team up against a new, even more powerful threat.
In a crossover with the DC Universe, Darkseid would be a great antagonist. His immense power and his desire for universal domination would put him at odds with Ultimate Gohan who stands for justice and protecting the innocent.
One potential crossover character could be Goku from Dragon Ball. Since Naruto has godlike powers in this scenario, a meeting with Goku, who also has superhuman strength and abilities, would be very interesting. They could have a friendly sparring match or team up against a common enemy.
Superman from the DC universe. Superman stands for truth, justice, and the American way, but his methods are often more lenient compared to Akainu. The two could have a philosophical debate about justice while also having to fight a common enemy.
A common pairing is Gohan and Bulma. Their relationship in fanfiction can be interesting as they are both highly intelligent in different ways. Bulma's scientific knowledge and Gohan's martial arts and Saiyan abilities can create a dynamic where they complement each other well.
If it's a crossover with the One Piece world, Blackbeard could be a potential bad guy. His ability to steal Devil Fruit powers and his ambition to become Pirate King could lead to a clash with Gohan. Gohan's pure - hearted nature would be in opposition to Blackbeard's more devious ways, and their battle could be epic, with Gohan's ki powers against Blackbeard's dark powers.
Luffy from 'One Piece' would also be an interesting crossover character. Imagine Ichigo being abandoned on an island in the 'One Piece' world. Luffy's carefree yet determined nature could contrast with Ichigo's more brooding personality. They could embark on a journey together, with Ichigo learning about the concept of the 'One Piece' and using his powers in unexpected ways within this new world.
Kakashi from Naruto himself could be part of a 'grey' themed crossover within the Naruto universe. Maybe a situation where Kakashi's past and his more mysterious side are explored further, and Naruto has to work with him in a darker, more complex mission that delves into the grey areas of the ninja world.
