Suggested by Eric Erwin has always been known as a solid tactical leader. He may use villainous tactics and has never acted like anything close to a hero, but if you don’t mind what methods are used as long as it attains victory then he is your man. On the other side of the field, Hanji has never really been known as a fighter and she mostly delights in attacking people who can’t fight back at the moment. She has some mild hand to hand skills and can use the equipment to slay titans, but Erwin is just a lot better at it than she is. He is tougher, faster, and has more experience. She will not be able to overcome this gap on ability. Erwin wins.
