An omega is the lowest ranking species in the omegaverse/alphaverse universe. Unlike it's alpha counterpart, omegas are generally kind, shy, sweet, smart, and hard working. Omegas tend to have a strong, sweet scent. They don't mate with other omegas, just betas and alphas. They go through heats, which are cycles of arousal when their body is readying for mating.
Stereotypical alpha: Yeah, Adam is a total omega. He's smart and sweet but he's way too weak.

fine swiss watch that is good enough for james bond and offers a much better value and is less showy than a rolex. Also the first watch to go to the moon, and still continues to be put in space.

Like Alpha, an Omega is one that USED to be superior and supreme getting everything without trying. But now, they are the shell of a former Alpha that is as normal as any other person. You could call them a Beta, though an Omega is far beyond the reach of a Beta. Omega is a wise and respected animal.
{The way to apply it to humans is as shown:Omega (fe)male/Alpha (fe)male/Beta (fe)male}
Owen: What should we do? We lost our captain!
Kase: Maybe we should ask Ryder! I've heard from the captain

he knows what to do with this because he's an Omega male!
Aiken: I think we need to have either a majority vote or just
make the person closest to the rank of captain be a temporary
pick.
