Well then, someone should tell Gorr THE GOD BUTCHER that! Then again, Jean Grey ascended to the ranks of Universal Concepts (beyond "gods" and cosmic entities) and turned Gorr into a star to shut him up because he was annoying her. So...I'd say she's earned her mantle at this point. She even says she's beyond a "god" in issue #5. God, in comic book land, obviously means a status of power, not a religious source of worship. Marvel and DC have been using that word for generations. It's nothing new!

There are too many Rogue fans in this thread that don't seem to understand what "limitless" means and how Omega level mutants work. Hope Summers is an Omega power mimic. Rogue can't even pretend to try to do what Hope can. Rogue is absolutely a whole badass, but there are limits to her powers. Hope doesn't have to touch anyone to mimic their powers, and when she does, they're boosted to Omega level status, and she instantly knows exactly how to wield them perfectly. You know who can't do that?

She's not Omega level. Yet. It even says that in the article. She may be eventually, but for now, she's an extremely strong Alpha. She's never once been listed as an Omega level mutant; and beating one doesn't make her one.

He didn't at the time. He's never been officially listed as Omega level until a week ago in X-Men #13. NOW it's official! He also describes Omega as potential power, not raw power. Jean and Kid Omega are still stronger than him now (Jean always will be), but he also hasn't unlocked his potential. Cassandra Nova pushed the limits and even she's stronger than Xavier, and she's his carbon copy. It took Jean Grey to finally take Cassandra down. Now that he's official, I'm sure they'll give him the boost he's deserved for decades.

She is #1. Even says it in her description. He just separated Earth/Krakoan Omegas from Arrakis Omegas. It does make the list pretty weird, but "Beyond Omega" makes it pretty clear that they're the top brass among other Omegas.
