Originally posted by leonidas@zop--yeah, that's one of the issues i referenced. and the PF went on to (arguably) destroy the universe in another issue. you're right though, non-canon (i think that was the same issue she crushed the goblin queen....?) but still, imo, telling as relates to the power phoenix could potentially access at its height.
There is also this. Rachel vs Shadow King. Shadow King at the time became the avatar of unnamed abstract forces. But it serves to show what the Phoenix Force can do or endow.
