Hi, I'm really new to Omegaverse! I heard somewhere that apart from Alpha, Betas and Omegas, there's such a thing as Sigmas? I don't really know if I can trust the internet source I got it from :(
I mean is not really a matter of trusting the info or not. Because Omegaverse is such an open concept in fantasy you can just invent whatever crap comes to mind and it'd be totally game.
There are people that like to incorporate more than 3 dynamics in their verse. I'm not one of these people. I think it's unnecessary, because as I see it the three dynamics already offer flexibility enough to encompass pretty much any type of person with any type of personality. I find it obsolete.
But you know a small sect of people in the fandom don't, and they like to incorporate these extra dynamics. There's nothing wrong with that, I just particularly don't do it. Though I did acknowledged it as part of the genre on a very old post abt the subgenres inside A/B/O, right here.
Their definition is also a bit different depending to whom you ask. So even if you ask me or someone else what these extra dynamics would be, people would have different answers.
There used to be a blog here on tumblr abt just these extra dynamics, but I don't think the chick that ran it is active anymore. So if I learn abt any blogs that like these extra dynamics and talks abt it, I'll either edit this answer or reblog it again with the info.
