I think Omegaverse is the term you are looking for. Omegaverse is a AU(alternate universe) in which males can get pregnant.
It is also a common universe for wolves. Wolves have an alpha which is usually the strongest wolf that is in charge of the pack. Omegas are supposed to be the weakest of the pack. So the omegaverse comes from the hierarchy of a wolf pack.
Oh so that's how it is! Thanks guys (￣▽￣)/
Can someone please explain me where the concept of alfa and omega came from? I have read about this concept in a couple of djs too.
