When is it stated that Aizen is twice as powerful as Ichigo? If you're talking about Aizen possessing twice as much spirit energy as the ordinary captains, thenit should be stated that Ichigo possesses much more spirit energy as the ordinary captain. Thus far at least as far as spirit energy goes Ichigo is second, only to Kenpachi.
