I see some have said that Aizen has no Bankai but the truth of the matter is that the only thing we know for sure is that it has not been shown. As for what his Bankai could be I do have a theory. If his Shikai has the ability to alter another's perception of reality I'd be led to assume that his Bankai can alter reality itself. I know it's an overpowered ability but it's not impossible considering all the other insane abilities we've seen in the series. The only problem is that Gremmy Thoumeaux already has that ability.
