No. No he really doesn't. Kenshin is normal human. Jack, and Zoro easily are super human. No matter his fighting style both of the players are simply way to fast for him. Maybe if Kenshin fought pre-crocodile zoro he'd have a chance since they're on even terms there he'd win but I don't see him defeating either of them. But you seem ardent on your support for both characters so I'll ask that we agree to disagree on terms of characters.

As for death battle itself I enjoy them but I don't take their fights seriously. Captain easily beats no-prep batman he has no pressure points for batman to take care of, Toph got a hell of a lot of advantages she had in her fight which were all situational on Gaara, and from what I heard Sol vs. Ragna was poorly handled and researched.
