A character from Bleach that is extremely powerful and NEVER dies. He seems to be a superman wanna-be at first, but he 'evolves' at random times. Recently, he is a butterfly...

That is right. The most powerful character in Bleach is now a f*cking butterfly. Fear his butterfly-ness.
Aizen is now a butterfly.

Aizen needs to die soon because no one likes him -____-

Hey! Look! A butterfly! No, wait... That's just Aizen
