Omegaverse is an alternate universe in which Mpreg is possible.,there are 3 main roles: ⍺, β & Ω
⍺ - dominant & able to impregnate Omegas. Male Alphas usually have a knot when aroused.
β - subordinate to Alphas & may or may not be able to impregnate Omegas
Ω - generally lowest on the hierarchy. Male Omegas are self-lubricating & can become pregnant
Each Omegaverse has its own variations depending on the writer .
