I've never been a fan of illusion techniques. In fact, I hate it all. Shinji's shikai, Aizen's shikai, every single ability that Itachi and Sasuke possess. >_>

And as far as Aizen's Bankai goes, don't be ridiculous - of course he has one. No Shinigami as powerful as him doesn't learn Bankai. With that being said, we will never see it. His Shikai was way too hax for Kubo to possibly think up a plausible and suitable Bankai. Plus, Aizen no longer has a Zanpakuto. Kind of hard to use a Bankai when you don't have a Shikai...
