Omegas are the least powerful of all werewolves. Derek tells us in season 2 that Omegas are lone wolves with no packs -- but the twins said they were the Omegas of their pack (before they, y'know, murdered them all) so obviously there's some way of being an Omega and being in a pack but it's not a way to be popular in a pack. We do not know how this works yet.

They said they were treted like Omegas by the pack they killed, however they did become Omegas in seson 3b and prasumibly Ethan is still one
