Hajime Hinata is also a great option. He has a relatable and determined personality. In a crossover, say with a detective - themed world like Sherlock Holmes' London, he could use his deductive skills (which he developed during the events of Danganronpa 2) to solve new mysteries. His journey of self - discovery in Danganronpa 2 could also be further explored in a different setting, as he tries to find his place in the new crossover world.
Chiaki Nanami could be an excellent choice. She is the Ultimate Gamer, so if you cross her with a digital or virtual world, there are so many possibilities. She could use her gaming skills to navigate through a new digital realm, like a Matrix - like world. Her calm and intelligent nature would also make her a great character to lead the group in a crossover situation. She could figure out the rules of the new world quickly and help the others adapt.
Makoto Naegi from Danganronpa and Yu Narukami from Persona. Makoto's determination and leadership skills could pair well with Yu's calm and collected nature. They could work together to solve the mysteries that occur when their worlds collide.
Ross could be really interesting. Since he's an archaeologist, in a crossover with a show like 'Indiana Jones' (in a fanfiction sense), he could go on an adventure with Indiana Jones. Ross would bring his academic knowledge while Indy would have the practical experience. Their interactions would be filled with Ross trying to over - analyze everything and Indy just wanting to get the job done.
I think Makoto Naegi and Robin would make an interesting pair. Makoto represents hope and Robin is always there to support Batman. They could learn from each other's positive outlooks. Also, Kyoko Kirigiri and Batman himself could be a great pairing. Kyoko's detective skills are top - notch, and she could either assist Batman or be a bit of a mystery for him to figure out as she has her own secrets.
Kuroko himself would be very interesting. His unique 'phantom' style of playing basketball could create some really unexpected scenarios in a crossover. For example, if he were in a crossover with a detective story, his ability to be unnoticed could be used to solve mysteries in a very unorthodox way while still having some basketball - themed elements in the story.
Ainz Ooal Gown would be a very interesting character to focus on. He has a complex personality and his vast power makes him stand out. In a crossover, seeing how he adapts to a different anime world's rules and cultures would be fascinating. He could be the catalyst for many interesting plot developments.
Lavon Hayes could also be interesting. He's a well - loved character in Bluebell. His leadership skills and big - hearted nature could be put to the test in a crossover. Maybe he has to lead the town in a joint effort with characters from another show during a crisis.
I think Naruto himself would be really interesting. His positive attitude and strong will would contrast greatly with the cynical world of The Boys.
Sinon from Ggo could also be very interesting. If she were to enter Sao, her sniper skills might translate in unexpected ways. She could be paired with characters from Sao and learn new combat techniques while also teaching them about the precision of long - range attacks.
Ax from the Animorphs would also be a great focus. He's an alien himself, so his perspective on Ben and his powers would be unique. He could compare and contrast his own Andalite abilities with Ben's Omnitrix powers. Plus, Ax is really intelligent and his knowledge of different species and technology could add a lot to the crossover story.
I think Alex Mercer would be really interesting. He has such unique and powerful abilities in the Prototype world. In a crossover with Naruto, seeing how he would interact with the ninja and their chakra - based powers would be fascinating. He could either be an ally or a potential threat depending on how the story unfolds.
