Ok, so my last david vs goliath matchup was a little unfair since one was a vice captain. I think this one might be good, one is a gatekeeper with legendary strength and the other serves a great captain and has antishinigami powers. Jinta is fast, can leap high, and has a powerful melee attack with his bat. On the other hand Jidanbou has a massively strong attack and is big. I'm assuming both Jinta and Ururu(sp?) both have anti-Shinigami powers since they don't seem too far apart in terms of power and he's taken down quite a few Hollows by himself. While Jidanbou is strong, Jinta is somewhat strong for his size and is a much harder target to hit.
