Mettaton EX

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. He has also shown soft spots for several characters, such as Alphys and Napstablook. He also appears to be among the fewer characters in the Underground that has no hate or prejudice against humans despite knowing about the monsters' history with them, since his initial attempts to kill the protagonist were just him playing along with Alphys's plan, and he outright tells the protagonist he has no desire to hurt humans and is far more interested in simply entertaining. While he did attempt to kill the protagonist, it was to prevent Asgore from taking their SOUL and be seen as a hero/savior to humankind, further emphasizing his lack of prejudice. This is also shown when he is killed during the Alphys Ending of the Neutral Route, even asking if the protagonist is "completely evil," showing they still have some faith in them. On the flip side, he has also been noted to be a very demanding boss who is very unpleasant to work for, especially according to Burgerpants, who initially considered working for him a dream, but has since grown to strongly despise him. Though this is contradicted by dialogue from Mettaton's other employees when he's killed in the Neutral Route, suggesting that Burgerpants is exaggerating, or this behavior is only targeted toward him.

Appearance: After having the switch on his back flipped in the Neutral or True Pacifist Route, 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.
