Let's review.4th = Naruto's Dad (Yeah, it's not like they look identical or use the same jutsu.)Tobi = Founder of Uchiha, Madara. (Not Obito, so stop saying he is.)Pein = Keyser Sosay!Jiriaya = So very dead.Wonder why Madara is around? I doubt he uses Oroch's Immortality Jutsu, and there's no way he's a puppet, but I doubt anyone summoned he because he was always with Diedara, and not the (hypothetical) summoner. Man, This series just keeps getting better.
