Form: A female torso extends from a multi-jointed, gaping maw of a demon, moving with the grace of a spider. Her body explores between necrogen and core metal structures.
Armor: Covered in a layer of greasy, corroded metal plates.
Voice: A soft yet grating whisper, constantly fed by informants, spies, and minions.
Ability: Capable of detaching into two parts, with the humanoid part docked into a massive, aggressive lower body. She can, though rarely, detach and glide to seek new homes.
