Orochimaru being the final villain... well I've complained enough about Orochimaru's cheap revival, but honestly I won't like. For me Orochimaru is lame compared to the past villains that have surfaced since his death like Pain/Nagato, Danzo, Tobi/Obito, Itachi, even Kabuto surpassed him. He'll have to get some insane upgrade to even keep up with the current big name shinobi because at this point I would call serious BS if he is on the same level as current Naruto and Sasuke. Honestly I hope once his field trip with Sasuke is done, I want Sasuke to just kills him again, and Naruto, Kakashi, Tsunade, or anybody else never even find out that Orochimaru was back alive again. The world has moved on from Orochimaru. I mean how can he even top the cheapness of Madara? Hmm, guess I'm not done complaining about Orochimaru's cheap revival after all.
Parena or Serecham both equal Serena+Pancham!
