Tobimaru he was second hokage
Really.... Is that why?
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 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.
