Re: Aizen Bankai !!!!!
Theory 1) Possible, but probably didn't happen. Aizen's shikai was so op, he was cutting down captains with ease. If his Bankai had already been stolen, it would have been shown already tbh. There's nothing to hide, after all it's a war.

Thousands of foot soldiers were killed, vice captains were caught off guard and Renji/Byakuya had their bankai's stolen which pretty much means there power has been halved.
The only way to enter the dimension in which the Spirit king resides is through the use of the "kings's key". Aizen obviously does not know another way in, because if he did, he wouldn't have needed to try and go to Karakura town and craft one there using 100,000 souls. And obviously Yama would never give the location of the original key to anyone else besides the future captain commander.
