Is that even how the Omega Level Mutant status work, though? Like, I was under the impression that you're either born as an Omega or you're not. Is there any known case where a mutant wasn't born as an Omega, but slowly evolved into one in the future?
Also, didn't someone from the X-editorial say there were no plans to add more Omega mutants to the list? So I'm not sure if Billy being a Omega will be a thing even if he gets confirmed as a mutant (which I honestly don't even think it's gonna happen anyway).
Jim, as far as we know, is only doing covers for Empyre, so I'm assuming this is going to be a cover for the main event... Either way, it's great to know Billy may show up in the main book. I really want to see him and Teddy kicking ass on a cosmic scale!
