oh i get you. your saying he has achieved a level of power beyond yami's already but cant use it. Well that is pure specualtion...im guessing you will refer to his hollow form beating the 2nd ressurection of Ulquiorra, but fact is we have no idea how strong ulqui was in relation to yammi or aizen and thus we cannot know how strong that full hollow form ichigo is in comparison to them. Thus there is no way to proove ichigo is stronger at the present time than yammi or aizen. case closed.
