Myth

Def not aizen cause hes in that ditch but he will be freed by kisuke to help bring down these clowns or maybe aizen knows their weaknesses and will remain tied up but tell kisuke.

So it took bach and co stealing powers to finally do what aizen did himself instead aizen used his haxxed out power and his haxxed out brain(def know who the better villain is).

Can't believe yama died in this way basicLly bach is a pussy who lacks the power to beat yama so he stole it and killed a powerless old man.

I wonder who will become the new commander i bet its shunsui
