***irama's Arsenal made to Counter Uchiha?
Think about it. He has shadow clones which, according to Itachi, are unaffected by Sharingan genjutsu.
He is the greatest master of water techs in history and fire loses to water.
FTG, as witnessed by the instant and complete defeat of Uchiha Izuna, makes him beyond Sharingan tracking. Also, its a fighting style which Sharingan cannot copy as it has no seals.
Also, Kabuto mentioned that only Kotoamatsukami is a strong enough genjutsu to override Edo Tensei control meaning that normal Sharingan genjutsu wouldn't work.
Tobirama seems to have made himself a lean mean Uchiha killing machine lol. What do you think?
