We already know the events with the Espada and Arrancar, and Aizen of course. But how would Aizen take a place in this arc? He already has been chosen to be locked up for quite awhile and if he ever got into enemy hands (you can guess the rest ._.).
idk how he plans on getting out, hes either going to join SS, or vs everyone. I think after juha bach is dead maybe aizen will return? need to see his bankai
As the guy above me stated Aizen will be more of blockade then an extra hand. Mainly due to the fact that Aizen has a god complex and wants to be the god of soul society so he wouldn't want soul society to fall just yet. And if you think about it, his help would be essential against juha because Aizen can trick him any which way he wants. Thus meaning that in a fight juha would have slight disadvantage though being extremely powerful as the manga portrays him to be.
So I havent been reading the manga i just watched the anime,but i hear Ichigo has quincy powers now??!! If so what are the extent of these powers?! Like what can he do?
Believe or not, Aizen s waiting Juha to weakening soul society as well juha himself through war.
When both side is weakening due to war, Aizen will be freed and solo all, soul society, quincy, hueco mundo, and human world.
