Who would be the most interesting character in a Ben 10 and Steven Universe crossover fanfiction?

Well, it could be really cool. Maybe the Gems would be intrigued by the technology of the Omnitrix. Steven might try to understand Ben's powers better and see if there are similarities between his gem powers and Ben's alien forms. And Ben could learn about the Gem culture. They could also exchange stories about their adventures and how they protect their respective universes.

Steven himself would be very interesting. His kind - hearted nature and unique powers would stand out among the Avengers. He could bring a new perspective to the team.

One interesting story could be a crossover with another popular animated series, like Adventure Time. Maybe Finn and Jake meet the Crystal Gems and they go on an adventure to save both their worlds from a common threat. It would be really cool to see how the different powers and personalities interact.

One interesting concept could be the characters' reactions to each other's unique worlds. For example, the nations from Hetalia experiencing the Gem society in Steven Universe. The different cultures and powers would create a lot of fun interactions.

One interesting storyline could be where Steven's gem powers interact with the magic in the Undertale world. For example, his ability to heal might have a unique effect on the monsters in Undertale. Maybe he could heal some of the more damaged monsters and in turn, they help him understand their world better. Another could be a story where the characters from both universes team up to face a common threat. The Sans and Papyrus from Undertale could join forces with Steven and the Crystal Gems to fight against a powerful enemy that is a threat to both their worlds. It would be really cool to see how their different fighting styles and powers work together.

One idea could be a crossover with "Adventure Time". Finn and Jake could visit Beach City and interact with the Crystal Gems. They could go on a mission together to stop a new threat that combines the magic of both universes.

I think Steven and Zim would be the most interesting pair. Steven's kind - hearted and positive nature contrasted with Zim's evil and self - centered personality would create a lot of comical and tense moments.

Definitely Steven and Dipper. Steven is so open - hearted and has a positive outlook, while Dipper is more skeptical and curious in a different way. Their different personalities could lead to some really interesting exchanges as they try to understand each other's worlds.

Enid from OK KO and Pearl from Steven Universe. Enid is a bit of a cool, laid - back character with her own brand of strength, and Pearl is a very refined and skilled gem. They could have a great dynamic, like Enid teaching Pearl some modern - day Earth things, and Pearl showing Enid some of her elegant combat moves.

I think Harry and Steven would be the most interesting. Harry has his own burdens of being the 'Chosen One' in the wizarding world, and Steven has to deal with his role as a half - Gem. They could understand each other's struggles and learn from each other's ways of handling difficult situations.
