Okay this is hardly related to FNaF at all, but this one is another OC character, one which's design I'm very proud of.

[FNaF AU story] Empress Ellen, was a metal born skin human tyrant from another dimension. William Afton studied her remains to build his circus baby animatronics, calling the robotic corpse as the mother of the death machines, thus making her the mother of the Circus Baby models.

[OC story] Empress Ellen is the self proclaimed empress of Carmine dimension after being banished there by her daughter, Circus Ellie. She is Redzina's arch nemesis, having had to deal with her a bunch in the past. She is the mastermind of causing everything to go wrong for her enemies, and besides; she's never too shy to get out of safety and fight on her own to be a menace. Her true motives are unknown, though she just seems to enjoy watching the world burn and claim everything in her name.
