He is voiced by Rev897.
Mettaton has a "fabulous" nature. He often speaks in a charming manner and has a rather narcissistic persona. But, at the same time, he deeply cares about the result his TV show has.
Mettaton makes a brief cameo. He is seen watching the reunion with an unhappy look on his face after Jessica yells at Asgore for murdering her daughter.
Mettaton is seen when Frisk, Bete Noire, Papyrus, Sans, and Asriel went to his first live performance. Betty soon decided to go say hi to him while presumably controlling a hallucination. He was seen meeting Betty before Papyrus (unintentionally) dropped large slabs of concrete onto the area.
- Currently, he has only appeared in his EX form, his NEO and normal form hasn't made a appearance in the series yet.
- His voice actor, Ultima Almighty, got his channel shut down for reasons he most likely doesn't want to be talked about. As a result, if Mettaton appears in future episodes, he will likely need a new voice actor. 
- Since "Dust" episode Mettaton doesn't appear.
- It has been confirmed that Mettaton will indeed return in Game Over after the song "Metal, Metal Crusher" was released on the official Glitchtale album.
