1. Phoenix
Who else could it be?
No one else on this list is at an Ate-a-Star level of power. Phoenix ate a star and killed millions. Billions. I mean, she is terrifyingly powerful. God level. It is frightening.
Now, arguably, Phoenix and Jean Grey are different beings, depending on how you view that retcon about her origins. If you say she’s Jean, she’s even more powerful, since Jean’s telepathy is among the best in the world. If you say she isn’t, then oh, well, she’s just a cosmic monstrosity who enjoys decimating star systems for funsies and to satisfy her appetite. Still pretty spooky scary powerful.
There might be some deeply powerful female superheroes, but Phoenix is easily the most powerful. She’s one of the most powerful comic book characters, period, and as a cosmic force of nature and pure unadulterated power, the firebird clinches the Number One spot.
And there you go, ten super-powerful superheroines. Not a comprehensive list, by any means, but a list of some notable ladies of comic book-dom who can lay down the law and kick some ass.
