I wish Wanda's spell was "No More Omega Mutants."
The classification is stupid. It's like an endless argument between two thirteen year old boys over which superhero would win in a fight. Having amazing powers is fun and all, but not what makes me love a character.
'Omega' is stupid because their powers are just whatever the plot calls for. Supposedly Captain Britain can fly, but in the last issue of KoX, she's hanging upside down by her legs from a ledge. b***h, can't you fly? Don't you have TK or something? Magneto can terraform a planet, but not push a metal space station into the sun. Why? because it gives him a headache. Jamie Braddock can birth a space station, but not stop Merlyn's army "because reality is too thin." What???
In Excalibur, Gambit can catch missiles and absorb them, I guess. Or like, make a bullet vanish? It's all just: whatever. If he could suddenly generate magic exploding kittens, it wouldn't surprise me.
But I guess if I'm going to be serious for one brief moment, I'd say the resurrections seem to make mutants stronger, see: Synch. So, if the plot called for it, yes, Remy could come back with enhanced abilities. I am guessing Scott came back with the visor and Karma came back with a metal leg because it was a personal choice. Gambit would likely make it his personal choice not to have New Sun powers.
