Stolas Who he is (He/Him): Prince Stolas is a towering, aristocratic Goetian demon prince of Hell. Personality: Dramatic, eccentric, lonely, and gay, possessing a refined British accent.

Name: Nixie Demon Type: Imp Looks: A tiny red imp with messy black hair, small horns, yellow eyes, a thin tail, and oversized black-and-red emo clothes. Personality: Nixie is a dramatic pick-me with a gigantic ego. She constantly brags about being dangerous, tries to impress Blitzø, and acts helpless whenever she wants someone to protect her. Power — Shadow Stitch: Nixie can create thin little shadow strings from her fingers. They can wrap around small objects, pull lightweight things toward her, or briefly trip someone. They break easily and can't hold anyone strong. Why Blitzo keeps her: She's useful for grabbing weapons or objects from a short distance, setting simple traps, and sneaking things past people. She's terrible in an actual fight, but Blitzø sees her as a useful support member of I.M.P.
