oh sorry i didnot understand your question before but if
Tobirama got mukoten he would be totally badass boss who himself would have gone to solo Madara=D
Her fighting style would have been different but at the end of the day, Naruto had to be the one to beat Pain and Madara would have still won, story remains the same =D
Lawd Tobirama would have had another badass tech tho
That would be bad. They would have to change the name of the clan aswell because it's the clan known to have 1000 skills.. Not just one. That's why Senju are more original then the Uchiha.I prefer Tobirama to remain the epc water style user..
