So what was his deal? Was he strong or not? They restrained him immediately and he did next to nothing but he was made out to be hokage level
I bet Danzo had Dan killed just because it bothered him that the guy had the best assassination jutsu in the verse. Dan was strong enough to glitch his way out of the undone edo tensei and give Tsunade a significant amount of chakra. The guy should be considered on the same tier as the white fang, high jonin low kage and a problem for everyone.
