Lets say he is alive.
@othus12: The picture is Edo Madara, so a slash wouldn't do anything. He wouldn't even need perfect Susanoo either, his regular one could block anything Fujitora uses, other than a meteor.
@Obito: Is this Edo or is he alive?
@Obito: Against Aizen's regeneration in Hougyoku forms, crushing force isn't gonna cut it. You'd need a powerful enough blast of energy that could wipe out both him and the Hougyoku, though I think it's debatable if Aizen can even regenerate in a fashion similar to Cell (regenerating from a single cell) or Buu (regenerating from dust) as the most we seen him regenerate was half his body after taking Dangai Ichigo's Mugetsu.
Now that I think about it, Aizen's flight advantage would make it rather difficult for the team to even connect with anything and they lack a sufficiently destructive attack that doesn't involve crushing force and could wipe out Kubo's Mary Sue excuse of a villain. Much as I hate to admit it, I'm gonna have to give Aizen the advantage in this match by roughly 70/30. I can picture Kamui, Sword of Totsuka or any random Sharingan genjutsu giving the Akatsuki team a victory if they time it right. But all the attacks are difficult to manage with (Kamui involving Obito making contact with his foe, Sword of Totsuka involving Susanoo which Itachi can't use for prolonged periods of time, said genjutsu involving eye contact of some sort) and Aizen's casual destructive feats in Hougyoku forms could be more than enough to deal with much of the team.
