Just how powerful is Itachi?

[NarutoB]

Hm.. what about his endurance? Will it be enough to solo someone as strong as Madara? Or, are you just messing with me?

Report anyone that says stupid shit like that

 

[Forbidden Tale]

High Jounin - Low Kage

It takes more than silly genjutsu and finger pointing

Defeating Orochimaru (kage level shinobi) with just 3T and low kage level.

He is very strong, upper part of top tier, he was part of top 10 before Ootsutsukis were introduced.

Itachi > madara
