A cunning thief could be an interesting character. They might be tempted to steal a precious item from the Everlasting Dragon or use its presence to their advantage in the underworld of the crossover world. They could add an element of mystery and mischief to the story.
Well, in addition to the main Dragon Ball Heroes like Xeno Goku and Xeno Vegeta, characters like Gohan could be great. His potential as a half - Saiyan is always interesting. From other franchises, Ichigo from Bleach could be included. His ability to use a sword and his Hollow powers would be a fresh addition. And of course, Spider - Man from the Marvel Universe. His quippy nature and his acrobatic fighting style would create some really fun interactions with the Dragon Ball Heroes.
Definitely Vegeta. His prideful and complex personality would add a lot to any crossover. For example, in a crossover with the Avengers, his initial reluctance to work with Earthlings could create interesting conflict. Another good character is Piccolo. His wisdom and fighting skills would be valuable in a crossover. If it was a crossover with the Mortal Kombat universe, Piccolo could hold his own against the likes of Scorpion and Sub - Zero.
Trunks is also a great choice. He has his time - traveling aspect which could be used in really creative ways in a crossover. For instance, in a crossover with the Terminator universe, Trunks could team up with the resistance against the machines, using his time - traveling knowledge and his sword skills.
In a Dorohedoro crossover with 'One Punch Man', Saitama would be an interesting addition. His overpowered nature would contrast with the often - more - gritty and complex power levels in Dorohedoro. Another good character could be Guts from 'Berserk'. His dark and brooding personality would fit well in Dorohedoro's gloomy atmosphere. Also, Edward Elric from 'Fullmetal Alchemist' could bring his knowledge of alchemy and his quest for truth to the Dorohedoro world.
In vegito crossover fanfiction, characters like Jiren would be great. His strength and stoic nature would make for some intense interactions with Vegito. Also, Android 18 could be included. She has her own unique set of powers and a strong will. Her presence could add some interesting dynamics, especially if she has to team up with Vegito against a common enemy. And don't forget Frieza. His evil nature and thirst for power always make for an exciting addition to any Dragon Ball - related story.
Kenny McCormick (Mysterion) could cross paths with Batman. Batman's detective skills and high - tech gadgets would make for an interesting dynamic with Mysterion's more 'underground' superhero style. They could work together to solve a mystery that spans Gotham City and South Park.
For a crossover with Doctor Who, the Doctor could be an interesting addition. He could bring his time - traveling abilities and vast knowledge to the Shadow World. And from the Shadowhunter side, Jace Wayland would be a good character to include. His charm and combat skills would make for some interesting dynamics with characters from other universes.
For a crossover with a post - apocalyptic world, characters like Mad Max could be involved. He might see the homunculi as either allies or threats in the harsh new world. In a crossover with a cyberpunk world, characters like Neo from 'The Matrix' could be interesting. The homunculi could be part of the complex digital and physical world that Neo navigates, and he could help them understand the true nature of their existence in this new, high - tech world.
In a springtrap crossover fanfiction, characters like the Purple Guy could be included. Since he has a connection to Springtrap, it would make for an interesting story. You could also include some original characters, like a brave adventurer who tries to stop Springtrap. And perhaps a mad scientist who created or is trying to control Springtrap.
The Powerpuff Girls would be great. Unikitty could join forces with them to fight crime in Townsville. Her magical powers combined with the girls' superpowers would make for an unbeatable team.
