If you're talking about bad qualities then none of the legendary 3 would make the worst hokage's ever. Jiraiya would the laziest, lech of a hokage who does not like anything administrative (he left Konoha to make smut novels !?) Don't get me wrong he's one of my fave characters but him, Orochimaru who would be like Hitler if her were Hokage aren't very good candidates. Tsunade I think is the best one even though she has many faults. That's whats so funny about the legendary 3 they're not the greatest people. However Ithink Jiraiya was right in getting Tsunade to do it because it also makes sense to have the best medic nin at home base especially when the population of working ninjas has dwindled greatly. Plus I LOVe her brashness, and short temper that balances off the laid back attitude of Jiraiya who is sort of a recluse. I guess I'm partial though cause I like strong female characters
