Backstory
Mattephantom is the ghost that later became Mettaton, and used to have an appearance that not quite matched his personality. While he had always surrounded himself with pink and acted much like a diva, Mattephantom looked like an unfeminine, brownish rag. His "dull" and "unshiny" appearance earned him the name "Mattephantom".
While he always believed to have come to accept himself and promised Napstablook not to leave him for a real body, he was confronted with a difficult choice when Alphys suddenly presented him the body he had only talked about before.
He chose to become the person he felt he was inside, and left his past identity and family behind to become the celebrity Mettaton.
