I think the loss of all powers is an issue. Iconic stuff should probably say, such as Mario's jumping ability.

It's not really a 'loss' of powers per say.  It's more along the lines of losing the understanding/ knowledge of the powers.  I think innate abilities like physical strength, or tough skin stay.  Although, I'm not sure how strong the powers will remain after coming through.
