Tobi_444
Tobirama was exceptionally skilled and powerful, Sage Mode was not one of his abilities (in my opinion he tried learning but unable because he have no talent for that). please don't make him typical MC ( 1. sage mode × 2. double triple template× 3. make realistic story where if he save nawaki it means butterfly effect are in play. In My opinion if nawaki remains alive it will change whole story like tsunade not leave village,oruchimaru don't seek immorality, Minato will not die because tsunade will because hokage (senju heritage). etc × 4. power : first hokage >fourth hokage>second hokage >=third hokage 5. Tobirama Senju is power no complane there but his main skill is that he was a master strategist, and contributed significantly to the development of the Hidden Leaf Village's infrastructure and military. )
