While it makes it more intense for it to be alpha and omega, it isnt caused by that....they have heat cycles that happen regardless of the other person involved. But for someone who doesnt really have those cycles (the beta) they will have a hard time of it physically as i am sure we are about to see
in a lot of korean omegaverse they have recessive and dominant alpha/omega. the recessive one don't get into heat/rut that often and their cycles are usually unpredictable i believe? sometimes heat/rut happens just because the omega/alpha is in the cycle for it. i think it is established (kinda) that only omega needs a permanent partner to keep their heat cycle normal. alpha don't need an omega to keep their rut cycle in check. but yeah things in omegaverse are different based on each author's preference most of the time.
I thought you can only put an alpha and omega together to cause that kind of reaction? I mean, I'm not complaining but I don't get it. also, if he's surpressing his alpha pheromones all this time, didn't that means he would need an omega to keep it stabilized? or is doing it with a beta can help as well? I'm so confused omegaverse is different in every comics.
