Nyanus

Nyanus is a sadistic little cat whose sole purrpose is to torment the subjects he oversees, which he does gleefully. He’s a miracle of contemporary engineering, combining intricate robotics and advanced artificial intelligence with a short temper and unquenchable thirst for violence. Despite his position as the Absolute Apathy Experiment’s overseer, Nyanus seems to have little interest in any scientific advancement being made, leaving his true motives shrouded in mystery.
