Who would win jiraiya of Tsunade

Well Tsunade isn't capable of sage mode, so that would automatically give Jiraiya an advantage. Although Tsunade has beat Jiraiya in the past for peeping, they have never went against each other seriously... Saying Tsunade's main strength is.. well, strength, and Jiraiya's sage mode makes him strong AND he has other strengths, Jiraiya would most likely win in a serious fight... although with Tsunade's healing ability I highly doubt he'd be able to KILL her, so he could only win something like a spar (otherwise Tsunade would win due to stamina). I donno if that made much sense, but I tried :p

I think Lady Tsunade would win... after all, he didn't do very well at defending himself when she nearly killed him for peeping. :P She is more... Vicious. Plus, not only can she do a lot of damage to her opponent with her monster strength, but she is ALSO an excellent healer, so... Sorry Jiraiya. I prefer Jiraiya's character (even though I love Lady Tsunade, too :D), but I think Lady Tsunade would win in a fight. X)
