Going from the top of the pecking order straight to the bottom: Omegas. According to most books on here at least. Not everyone includes them, but they do share a lot of traits when they are included.

1.) The Pack Servant
Somehow one person, who's supposed to be weaker than everyone else mind you, is able to cook and clean for an entire pack. In most cases these packs are described to have hundreds of members. I'm sorry, this person has to be a superhero amongst lazy slobs. Do they starve when the person ultimately leaves in every story?

2.) Punching Bad
If you think being the built in made was bad enough, try being designated pack punching bag! Don't worry, we don't charge extra for the trauma that you'll get over within 3 or 4 chapters. That comes free!

3.) I'm the weakest in the pack, but I managed to run away while the entire pack was chasing me
Sorry hun, you can't have it both ways. Someone is bound to catch up with you. What am I talking about? Omegas are KNOWN for their god damn plot armor.

4.) Freakishly Tiny
You want to be an Omega so bad, sorry you have to be under 5 feet tall. Thems the rules. We can't have any average, or gasp an above average, height person as an omega. Sometimes when reading these stories, the description of the main character doing certain things feels borderline ... uhhmmm .. when they're described as these tiny human beings. Or I guess werewolves. You know what I mean.

5.) No Ones Seen an Omega in 58272829 Years
Again with the really "rare" main characters. If it's been this long since someone has seen a certain thing, they're not gonna believe it's the thing. It becomes even more unrealistic when it comes to Omegas. Why would there still be a rank title for something that hasn't been around for that long? Make it make sense.

***
And that's a wrap. I'll probably add more to this one. Again, if you can think of any other clichés please comment them! Until next time, stay cool? Idk how to end this thing off.
