Mettaton is a confident, charismatic, and charming TV host that loves drama, action, and violence. He lives for his ratings and adores performing. He supposedly strikes a pose when he does something wrong and makes time on his various shows to beat up "heel-turning villains." He shows a rather shallow appreciation for existence at times. He has a strong craving for attention and seems very egotistical, shown when he boasts about the beauty of his true form. However, despite his seemingly self-centered personality, he deeply cares about the seemingly positive impact his show has had on the inhabitants of the Underground. After having the switch on his back flipped, Mettaton transforms into Mettaton EX, a new body he specially requested Alphys make for him. In this humanoid form, he has black hair with a long fringe that seems to cover his right eye, pale "skin" and visible metal segments below and above his left eye. He has a pink chest piece, a narrow metallic waist with a box contraption, and black shoulder pads above his segmented arms, which end in gloves. The chest piece has what appear to be a speaker and some knob or gauge, while the waist has two parts that seem to act as a locking mechanism that holds his "heart-shaped core", as they both lose white pixels during his "heart-to-heart" attack. His long black-clad legs end in pink high-heeled boots. He has a broad-shouldered, sleekly frame with a dramatically tapered waist that creates a pronounced hourglass silhouette. His hips flare outward noticeably, while his thighs are especially large, rounded, and full, giving his lower body a very curvy appearance. His arms and neck are long and slender, contrasting with the heavier hips and legs.
