Aight this is for my followers who are familiar with the omegaverse. If you don't know what that it, thenthis isn't for you. I wanted to put my two cents into this because I have this addition to it that I came up with (at least I think I have, I haven't seen anything on it so im not sure).
I call this new addition the Delta Update.
Delta's are non-reproductive classes that exist to protect omega's from rogue alphas. It is up to the author (if you wish to use this idea), to decide how the Delta gene is passed, but the basics are that they are chosen by omegas to protect them when the alphas are unable to. They are pretty much immortal soldiers, bound to their omega till the omega dies. They are naturally aggressive to all alphas except for their assigned omega's alpha. They are somewhat friendly to betas and other omegas, to the point where rogue delta's protect random omega's from alphas and can become friends with betas. The omega's "mark" the delta's with carved triangles that leak with the omega's sent, warning alphas that that delta is assigned to an omega. Their senses are heightened to allow them to protect omega's easier. They do have weaknesses, but whatever they are depends on what the author wants. Also, everytime they kill an alpha on behalf of an omega, they'll gain a burned in omega mark on their back signifiying that they are the protector of those omega's. How the alphas know that is up to the author. They are also mentally unable to feel romantic or sexual feelings. They're basically just soldiers that protect omegas. But thats my 2 cents on the omegaverse, do y'all like it? I'm still workshopping it but this is what I have. Enjoy! (If you use this idea, please tag me)
