True!! He is boss... But I saying about the rest of them.. Kakashi, Shikamaru and even that frog sage who was fighting with Jiraya were not able to understand.. What do you think??
I am not really sure.. Because when he was fighting pein.. and that slug told him there was another pein controlling them, who was the main one.. He was surprised..
They never heard or known of any ability like that so they were only making guess about the ways they knew are possible like genjutsu and immortality.
who could think that a man can control 6 dead body's from a far distence and use such high lvl jutsu and also talk through them,so no i do not think that they are dumb.
Dude, you're only saying that because you know now.
They didn't even know Pain was coming toward the Leaf. Pain surprised attack the Leaf.(Lets all ignore him and find Nagato.)
1. They never seen nor heard of the 6 Paths of Pain before.
2. The Pains separated. They scattered across the village in search of Naruto. Not to mention he also had summoning destroying the village.
3. They had little knowledge of his power. They heard what he could do, but didn't know which Pain did what.
