Everyone talking about omegaverse here seems to not particularly enjoy the concept and that's understandable considering how it is usually depicted. But I thought I would offer my view as someone who absolutely loves it. As in I filter fandoms on AO3 particularly looking for them 😅
Reason 1: Porn, no denying that. I tread on the side of forbidden love or toxic relationships.
Reason 2: The non-toxic omegaverse. While a lot (a lot 🫠) are depicted as 'loss of control' and 'not consensual', that is the decision of each author. So, of course, some authors have chosen to not write those types of elements in. So yes, there are fully consensual, no toxic main characters, fully sweet and romantic omegaverse stories. There is even a published book by (forgive me if I mistake this) a male writer who wrote a omegaverse gay novel just like this. Now, this isn't the majority and usually only people who have tend to like omegaverse have seen them.
Reason 3: The study of ingrained patriarchal rule. I think most of us have heard of ingrained racism, well this is the same concept. I love how it brings to light my own or others very ingrained and personal biases on gender roles and very few concepts will highlight it as well as omegaverse will. I saw a comment on a clip of Phatsa's first fight scene and it said something like 'I thought he was the omega?' Did they think omegas couldn't fight? Why? It's those thoughts that fascinate/challenge my own reasonings.
