Rofl, I know right?! Care to ellaborate?Really.... Is that why?
You were right the first time she's the 5th Mizukage.just because hes 2nd hokage means hes stronger then the 5th mizukage? pshh or the 4th. i forgot
anyways
Mei and Zabuza with high difficuty
tobirama banned edo tensei he wouldnt even use it to save his own life.Tobirama win , his suiton level is largelly higher than the mist's ninjas.His great chakra level will permit to defeat them with pure ninjutsu,his genjutsu will make a lot of trouble at Mei and Zabuza ,and edo tensei as trump card it's overkill.
