#I made Alastor an omega because I thought it would be really funny if he was the “weakest” tertiary sex

[prince-liest]

In your omegaverse insecure beta Vox AU, would Vox have pretended to be an omega if Alastor was an alpha? Or would his internalized whatever not allow him to do that?

He would probably have pretended even harder to be an alpha. Most of his desire to present as an alpha isn't specifically to be the societally ideal partner for Alastor - it's to present himself as a societally ideal powerful man.

Alastor being an omega who is so effortlessly powerful grates but is something Vox is able to dismiss to a certain extent because as an omega Alastor isn't even really in the game of trying to attain acceptable alpha-hood (which has significant overlap with toxic masculinity and the persistent pressure for people to prove themselves as worthy of their own gender), but Alastor being an alpha who is still effortlessly powerful despite clearly putting little to no effort into the particular kind of showboating that Vox has to engage in to feel like he's even starting to "do it right" would just make Vox feel even more insecure standing next to him.

It would probably just shift his psychosexual obsession with Alastor from "I am going to dominate you beause that's what a real alpha does to omegas" to "I am going to dominate you to prove that I'm better at being an alpha." Cue wildly oscillating between trying to emasculate Alastor for not trying very hard to align with what Vox thinks makes a real alpha, and being frustrated that Alastor is so secure in himself despite not even trying.
