Omegaverse X-men but the sub gender matches the power level.
Omega gender? Omega Class.
Jean Grey with the powers of a fiery god? Omega
Magneto who can invert the magnetic fields of the earth with a thought? Omega
Ororo Munroe, Storm, Mother Nature come again? Omega
That inadvertently creates a whole new culture in the mutant community because if a mutant comes to you and you can smell a sweet and inviting omega scent the humans may subconsciously think about the omega stereotypes of meekness or emotional instability or how they are only good to taking care of the pups and only an alpha can handle these serious affairs bla bla bla
While the mutants in the room collectively go “shit fuck shit fuck a Matriarch is here!!” and they all start to straighten themselves to both impress (because the matriarch may like you and give you protection in their pack) or make yourself less threatening (because they may hate your vibes on sight and delete you from existence WHO KNOW???)
This brings us to Charles Xavier.
Professor X, who is an Alpha level mutant (depending on the continuity) but is also an Omega Level Telepath (also depending on the continuity)
If he is an Alpha, his and Erik’s divorce has been wrecking the X-men and the Brotherhood packs for nearly 5 decades now (the x-men because they are Matriarchless which is wrecking their whole dynamics over there and their Patriarch is suddenly blind to his ex husband nearly KILLING THE PRESIDENT AGAIN CHARLES OMG?!?! and the Brotherhood because their Matriarch is going ballistic over that bald man for 50 years now and NO DONT LEAVE OUR MISSION TO SAVE YOUR EX WHAT ABOUT OUR GOALS?!?!)
If he is an Omega, the X-Men vs Brotherhood is actually both a divorce (omega/omega marriages are frowned upon but who is stopping them?) and two Matriarchs fighting over who is the better mom, provider and protector for the family (all mutant kind)
In both scenarios they meet once a month to play chess and fuck nasty
(Also as a bonus for the last scenario: Logan is classified as an Alpha level mutant…
Charles and Erik, both Omegas, wanting pups: *see Logan who is strong and capable and caring under all the grumpiness and nearly indestructible* this one will do
Logan, getting levitated by his bones: what
)
