Glad you remember me ^^
Nah it's okay lol, I'll gladly explain what it is.
So, the Omegaverse is an AU genre where people are divided into secondary genders, Alpha (often portrayed as a top, confident, protective, or dominant), Beta (similar to ordinary humans and usually unaffected by Alpha/Omega-specific instincts), and Omega (portrayed as soft, weak, a bottom) in addition to being male or female.
It's like werewolf dynamics. They'd be going at it, they'd going into heat.
That's why I've been wondering which one you'd think suits your characters.
Oooooh. I thought you said Gameoverse for some reason pff. I never really thought about it, this au is new to me. I generally see Cid being more forward and Krail being a little more submissive but I never liked putting stereotypes on characters in a dynamic. I like there to be some sort of balance in the dynamic depending on the situation. Cid has a werewolf form in the monster au which can be very overwhelming for Krail so take that how you will.
