I'm a certified Villain Enjoyer so I have a lot of characters that fall into the antagonist roles (and a lot of protagonists that act like villains lol) Here's a few! Sheldon is the closest to a major antagonist that humanverse gets, with Max being a close second. Dind has a LOT, but the most central is probably The Chancellor (and for funsies, Dez is an antagonist-turned-protagonist!) Kayda is the main antagonist of Magical Girl Subverse, though she's maybe one of the handful of genuinely good people in the whole cast, and the Big Bad behind her is Mitsuuo. Nevada is behind most of the bad things that happen in Fallen Kingdoms, both on a large scale and a personal scale, the absolute worst lol. Ms. Fox isn't the main antagonist per se, but I like her better. Eggshell is the leader of our OC Decepticons, so that's pretty self-explanatory. I also have Yaeko, Jun, and Ai that are still wips. Orange Diamond, Saffron Blue Diamond and Dovepaw are also some big favs!
(not even 'evil' characters, just the 'bad' one of the story!)
title is self explanatory!
I have a few, but she's the antagonist of all three of my POV mains so she wins the spot here.
Ironically, she's not "evil" if that makes any sense. She just has an agenda she wants to follow, but the mains are in the way if that, or they want to stop her. Her background is a lot to explain.
