Banjo is a pretty resourceful fighter. He has a bit of super strength which comes in handy in just about any fight. That’s not going to be enough to stop someone like Rei though. Rei has a ton of talents of her own including a powerful guardian who can amp up all of her attacks. She also has a few different transformations up her sleeve which make her abilities even better. Banjo just won’t be able to keep up and his brief invincibility will be too brief. Rei wins.
