The interaction between Robin and Batman would be really interesting. Robin has his own identity with the Teen Titans now, and Batman is his former mentor. There would be a lot of unspoken history and emotions. Batman might be proud of how Robin has grown, but also a bit overprotective. And Robin would be eager to show Batman that he can handle himself without his constant guidance.
I think Robin from the Teen Titans and Batman would be really interesting. Robin has his own set of skills and experiences with the Teen Titans, but he also has his roots with Batman. Their interactions could range from Batman being a bit overprotective to Robin showing off what he's learned with the Titans. It would be a great exploration of their relationship.
Batman himself is often very popular. He brings his detective skills and brooding presence to the stories. Robin is also a favorite, especially since he has connections to both the Teen Titans and Batman. His growth and development in these fanfictions can be really engaging.
In a 'Teen Titans meets Batman' fanfiction, there could be an epic battle. Maybe the Teen Titans initially mistake Batman for a threat and they engage in a fight. Robin, being Batman's sidekick, might have to step in to clear the misunderstanding. Then, they could team up to face a common enemy like the Joker or Slade. It would be amazing to see how Batman's detective skills and the Teen Titans' unique powers combine to solve a mystery or save the day.
Definitely Doctor Strange and Loki. Loki is a master of trickery and Doctor Strange is a master of magic. Their interactions would be full of mind games and magic duels. Loki might try to deceive Strange, but Strange would see through his illusions with his magic.
The interaction between Starfire and Beast Boy would be fascinating. Beast Boy can transform into different animals, and Starfire has her own set of superpowers. They could have some really fun and comical moments together, like when Beast Boy turns into a small animal and Starfire is trying to figure out how to communicate with him. Also, they could team up in battles in really creative ways, with Beast Boy using his animal forms to distract enemies while Starfire blasts them with her energy.
Definitely Naruto and Sasuke. In a 'past Naruto meets Boruto' fanfiction, if Sasuke was also involved in the meeting, it would be really cool. Boruto could see the dynamic between his father and Sasuke, two of the most powerful ninjas. He could learn about their past rivalries and how they overcame them to become allies. It would be a great opportunity for Boruto to understand the importance of having a strong bond with your comrades.
I think Kakashi's interaction with Minato would be very interesting. Kakashi was Minato's student. Meeting his sensei again, especially with Team 7 in tow, would bring back a lot of memories. Kakashi could show Minato how he has grown and passed on Minato's teachings. And Minato could give Kakashi some new insights based on his own experiences.
Adam West's Batman himself would be really interesting. He has that old - school charm and a unique way of dealing with villains. His presence would bring a lot of nostalgia and also a different perspective on crime - fighting compared to the modern Batman.
Obviously, Nightwing himself is very popular. His skills, charm, and his connection to Batman make him a central figure. Starfire is also quite popular in these fanfictions. Her alien powers and her unique personality add a lot of flavor to the stories. Beast Boy is another one. His ability to transform into different animals often leads to some really interesting and funny scenarios in the fanfiction.
Definitely Naruto and Beast Boy. Imagine Naruto being amazed by Beast Boy's ability to transform into different animals and Beast Boy being curious about Naruto's ninja skills. They could have some really fun exchanges, like trying to outdo each other in terms of speed or stealth.
