HOLY SWEET JEEBUS! The theories are just coming out of the wood works now!
Kabuto just used his ressurection tech to bring back the ACTUAL Madara and now we finally have some proof that Madara isn't all he cracks up to be! I'm still leaning towards Obito still being alive and taking on Madara's name. We only see him with one eye most of the time so I'm thinking it's possible that Obito survived and was rebuilt to believe he's Madara. I want to say it's suspicious that none of Kakashi's teammates were brought back, but considering how young they were and inexperienced, it makes sense that they weren't.
BUT HOLY GEEZ WHEN ARE WE GOING TO FIND OUT WHO "MADARA" IS?! The wait is killing me!!
