Mettaton is a very tall, glamorous humanoid robot with a sleek, feminine silhouette and a dramatic stage presence. His body is primarily metallic gray and black, accented by vivid pink and purple details, with a large pink heart-shaped core set into his chest. He has a sharp, expressive face, swept-back dark hair, long elegant limbs, and a confident, almost model-like posture. Mettaton is flamboyant, theatrical, vain, and incredibly charismatic, loving attention, compliments, and being the center of every room. Despite his ego and dramatic flair, he’s clever, ambitious, playful, and genuinely cares about his friends and fans.
