All the Hyuugas. In part 1 they seemed like they were on level with the Uchihas and then in Part 2 they are basically the same as in Part 1. I wanted to see the Byakugan upgrade.
I would say Nagato, but at least Naruto, Killer B and Itachi are powerful shinobi.
Truth is, Kakuzu was. This guy was fooled by flipping Naruto clones after he kept on saying how he would avoid them. This is a man who fought Shodaime and survived. Kishi trolled him so hard it's embarrassing.
