Definitely Naruto himself. His energetic and determined personality would make for great stories in the Buddyfight world. He could bring his never - give - up attitude to Buddyfight battles and inspire his Buddy Monsters in unique ways.
Sakura could be very interesting. In fanfiction, she could use her medical ninjutsu skills to heal Buddy Monsters during battles. She might also develop a new fighting style that combines her ninja skills with Buddyfight strategies.
I think Naruto would be really interesting. He has such a positive and determined personality. In the fanfiction, seeing how he reacts to the strange world of Inuyasha, with all its demons and magic, would be great. He would probably try to make friends with everyone and his never - say - die attitude would be a big asset when facing the dangerous demons in Inuyasha's world.
Tsunade would be the most interesting. In Naruto's body, she gets to relive her youth in a way. She can experience the energy and the naivete of a young ninja again. Also, she has to adapt to Naruto's relationships with his friends and sensei. Her attempts to train Naruto's body as if it were her own while still having to fit into Naruto's life would be full of drama. She might also use her wisdom and experience to improve Naruto's standing among the other ninjas in a different way than Naruto himself would.
Hinata would be a great choice. He's so full of energy and determination. If he traveled back in time, he could share his experiences of playing against strong opponents like Nekoma and Aoba Johsai with his younger self. It would be really cool to see how his past self would react and grow even faster with that knowledge.
A Skaven character could be a lot of fun. Their sneaky and conniving nature would create all sorts of chaos in the school. They might be constantly trying to steal secrets or sabotage other students in order to get ahead. And the other characters would have to figure out how to deal with this devious new presence.
Bakugo could also be a great choice. If he went back in time, he might have to face his own arrogance from the past and try to change his ways earlier. It could be a journey of self - discovery for him as he realizes how his actions in the past affected others and how he can be a better person and hero in the future.
Hook would be an interesting character for OUAT time travel fanfiction. His past as a pirate and his relationship with Rumplestiltskin are full of drama. If he were to time travel, he could go back to when he first lost his hand to Rumplestiltskin and try to change that event. Or he could travel to a time when he was a more ruthless pirate and see how that version of himself compares to the man he has become.
Iruka Sensei could be a really interesting interviewee. He was Naruto's first teacher and someone who really believed in him when others didn't. He could talk about what it was like to teach Naruto and the other students, his own experiences as a ninja, and how he feels about the changes in the Hidden Leaf Village over the years.
I think Naruto and Weiss would have some great interactions. Weiss is from a high - class family and is very proper, while Naruto is this rough - around - the - edges ninja. Their clash of cultures could lead to some really funny and also some really deep moments. Maybe Weiss could teach Naruto about the importance of elegance in combat, and Naruto could teach Weiss about the value of hard work and determination from his own experiences growing up.
I think Kakashi would be very interesting too. His experience and wide range of jutsu would be valuable in a zombie - filled world. He could use his Sharingan to copy any unique abilities the zombies might have and use it against them.
Definitely Gaara. His ability to control sand is unique. In the Borderlands 2 setting, he could use his sand to protect his teammates from the various attacks, like from the psychos or the Loader Bots. His transformation into Shukaku could also be a very powerful and visually striking element in the crossover.
