@Soda , reading your reactions are very fun to me. You are to the point and quick to point out what you notice and think.
Cozy reminds me a lot of the villain from Cats Don't Dance. The staff on MLP may give her a reason why she's evil in a flashback scene, but for now Cozy is evil just for the sheer fact that she can be. In her mind she doesn't need a reason to act the way she does, it's how she's always been thinking.
"Gregory" / Grogar is the one I am curious about. I don't really know how exactly he wants to do things. He obviously knows about the friendship rainbow beam/power ups...maybe he wants the villains to have their own villainous beam of power to combat that friendship magic. I dunno.
