Who would be the most interesting character interactions in a Ben 10 and Young Justice crossover fanfiction?

The interaction between Ben and Robin would be really interesting. Robin is a great strategist and detective, while Ben is more of a brash hero who relies on his alien forms. They could learn a lot from each other. Robin could teach Ben about planning ahead and thinking through his actions, while Ben could show Robin how to be more adaptable in combat by using different alien abilities.

The interaction between Spiderman and Miss Martian would also be fascinating. Miss Martian has telepathic and telekinetic abilities. She could be intrigued by Spiderman's mind, which is full of scientific knowledge and quick - thinking strategies. Spiderman, on the other hand, could be amazed by her alien powers and learn how to better use his own abilities in combination with her powers in combat situations.

Robin from Teen Titans and Robin from Young Justice would definitely have an interesting interaction. They both have leadership roles and similar names, but their leadership styles might be different. They could compare notes on leading their respective teams and learn from each other.

Danny and Robin would have really cool interactions. They're both young heroes who are very intelligent. Robin could be intrigued by Danny's ghost powers and how they work, and Danny could be interested in Robin's detective skills and gadgetry. They could bounce ideas off each other when it comes to solving problems and fighting villains.

The interaction between Naruto and Miss Martian would be quite interesting. Miss Martian has her telepathic and shape - shifting abilities. Naruto, on the other hand, has his chakra - based powers. Miss Martian could be intrigued by Naruto's chakra system and Naruto could be amazed by her mental powers. Also, Naruto and Beast Boy could have some fun interactions. Beast Boy can transform into different animals, and Naruto might find that really cool and they could come up with some unique battle strategies together.

I think the interaction between Ruby and Ben would be really interesting. Ruby is very energetic and has a strong sense of justice. Ben, with his experience of using the Omnitrix to save the day, could share some of his stories with her. They could also have some friendly competitions regarding their combat skills, like who can take down a group of Grimm faster, with Ruby using her Crescent Rose and Ben using one of his alien forms.

Definitely Ben and Batman. Batman would be intrigued by Ben's Omnitrix and his ability to transform into different aliens. He would try to analyze it while Ben would be in awe of Batman's detective skills and gadgets. It would be a clash of two very different mindsets - one a young, impulsive hero and the other a brooding, strategic one.

Another interesting interaction could be between Gwen (from Ben 10) and Nami (from One Piece). Gwen's intelligence and magical abilities would contrast with Nami's skills in navigation and her love for treasure. They could exchange knowledge, with Gwen teaching Nami some basic magic spells in exchange for Nami teaching Gwen about navigation techniques across the Grand Line.

Goku and Superman would be extremely interesting. They are both powerful heroes with a strong sense of justice. Superman might be intrigued by Goku's Saiyan heritage and his ability to constantly increase his power. Goku, on the other hand, would be excited to meet someone as strong as Superman. Their initial sparring match could be epic, with both testing their limits. Another interesting interaction could be between Goku and Batman. Batman would be very cautious around Goku, trying to analyze his weaknesses. Goku would probably be a bit confused by Batman's lack of obvious superpowers but would respect his intelligence and combat skills.

Rorschach and Batman would also be a great pair. They are both dark, brooding characters who are very dedicated to their own versions of justice. They might start off clashing due to their different methods, but eventually find common ground in their pursuit of truth.
