Naruto Shippuuden Episode 16

well i do believe more than 30% chakra can be placed in the clone and to prove kisame said "we only placed 30% chakra into them", it was a bold statement giving us our answer.
Know some things to think about...

-with 30% chakra into the clone, what about the clones chakra, does their chakra add to the 30%?
-why is itachi so strong, he isn't a jinchuuri (sorry for spelling) nor did he so something like sasuke did, so why is he so strong?
-One of the clones is from the sand village, he was there for four years, and when the old lady said something about when the clone joined the sand vill. the timing was just right when akatsuki was making their move or something like that, does that mean the clone was under control the whole time or was he a spy for akatsuki not being controlled?

Edo Tensai is the most broke move in the entire series. So far we have not seen any possible way to beat it aside from summoning the death god.

You could always just be more powerful that the guy doing the summoning and all the dead people he summons.

When I rewatched Naruto, I skipped the Orochimaru vs Third battle simply because I can't understand the Edo Tensai. The past Hokages were supposed to be really great people, yet if you summon their spirits, it seems to be child's play to make them go against everything they believed in while living in full power? What the heck is that? I have to agree with Assertn even if for different reasons: I can't consider it but a broken move until it's explained in such detail that even I can figure it out.

Oro is certainly powerful, but if one of his best moves is one I can't accept, then I have troubles considering him really strong compared to people who give me no such troubles.

Well this could water down to "ninjas are tools", which was examined in the Zabuza arc (credit to XanBCoo for the reminder). Even though they have their original spirits, they are still the attack dogs for whoever controls them.

It's like in Bleach, Byakuya's single-minded following of the rules of Sereitei and the judgment of the office of 46, even if it means his little sister dies.

1. We don't really have a lot of other Uchiha to compare him to. All we know is that the Uchiha were once the villages strongest clan and I think it was said that only 2 or 3 other people in the Clans history had achieved Mangekyu. We have no idea how strong those others were in comparison. On top of that he can use Tsukuyomi which seems to be a stronger version of the Mangekyou, and something that was never mentioned as being used by the others who had achieved Mangekyou. Basically for all we know he's just simply reached the maximum strength possible for a member of the Uchiha clan.

2. If you go back to the Episode where Sasori and his partner approach the sand village there is a part where Sasori activates some kind of technique he had placed on Yurra. It appears that until that technique was activated he was loyal to the sand and had no memory of whatever interaction he'd had with Sasori previously. So i suppose the answer is that he was being controlled, but not until Sasori showed up at the Village of the sand and reactivated his technique.
