Aizen didn't really need a Bankai, since whenever someone managed to injure him, the Hogyoku would simply make him stronger, and that was part of Aizen's plan. In Aizen's final fight against Ichigo, they were both on a level where a mere Bankai probably wouldn't have done much damage anyway. Aizen also thought of himself as being superior to Ichigo, and if he were forced to use his Bankai it would prove that they were equals. Simply put, he was too proud to use his Bankai. (...) A bankai is between 5 and 10 times as powerful as a Shikai, and he didn't even use his Shikai against Ichigo, who knows, maybe it could turn at least a bit the battle's winner. But anyway, i ask myself why Aizen hasn't used his Zanpakuto in the battle with Ichigo, maybe overconfidence? Or maybe when he evolves from the Hogyoku he can't use it anymore?
