In a crossover with the Avengers, Iron Man could be an ally. His high - tech gadgets combined with Gohan's power would be a great team. Also in the Pokémon world, Ash could be an ally. Ash's knowledge of Pokémon and Gohan's combat skills could be useful. In the Bleach universe, Ichigo could be a strong ally for Gohan, with their combined sword - fighting and energy - blasting abilities.
Obviously, Gohan as a girl would be the main character. His family members like Goku, Chi - Chi, and Goten would likely be in the story. They would have different reactions and interactions with Gohan in his new form.
Bulma could be one. She's a well - known character from Dragon Ball. In a harem - like scenario, her intelligence and resourcefulness could add an interesting dynamic to the relationship with Gohan. Also, characters from other animes like Asuna from Sword Art Online might be included. Her sword - fighting skills and kind heart could contrast and complement Gohan's powers.
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.
In a crossover with the Bleach universe, Orihime could be part of Gohan's harem. Her kind and gentle nature might be attracted to Gohan's heroism. Rukia, with her strong will and sense of justice, could also find herself drawn to Gohan's similar qualities.
Gohan himself could be a main character in some form. Maybe he exists in Naruto's memories or as a spirit guide. Another potential main character could be Sakura. She might be interested in Naruto's new powers and try to help him understand and control them. And of course, there could be new characters introduced from Gohan's world that interact with the Naruto characters.
