However you define villain is fine, there are no rules for this :) Villain aesthetic, lore, both, neither, whatever kind of villain you've got. I just wanted to share my pack's villain because the black traveller's cloak completes his outfit!
Ooh both you and @Wildsinger have such pretty wolves!
Here's mine! He's less a true villain and more of a misguided one, but I think he still counts (especially aesthetically!!) :) I haven't written an incredible amount of his lore yet, but every member of his den will have a short story in their bio about him! It's a big project though lol
OH! Yes, I just recently finished writing the lore for my villain and she has made her way to the top of my fav OC list. Her lore recently has her found by my pack and "restored" (healed and rejecting her life of darkness), but she has been a villian up until now. The pack isn't necessarily fond of her yet, especially after having to go to war against her, but she's adjusting.
Don't mind the insane wall of text in her bio.... that's just a summary lol.
Super short summary:
She was a consumed with dark magic most of her life and preyed on unsuspecting travelers whom she stole from, cheated, and acted cruelly towards. She was insanely powerful.
Neither of these wolves are actual villains, since The Wastelands world of mine doesn't necessarily have villains, but they certainly have villainous personalities and would definitely make some amazing villains.
