Mettaton is a robot with a soul who is the Underground's most popular (and only) celebrity. While initially built by Dr. Alphys as a "human hunting machine" in an effort to impress Asgore, Mettaton decided to go his own way and become a hit television star. Through a bit of research, Frisk can discover that Mettaton was initially a ghost (specifically Napstablook's cousin) who had a fascination with humans. Quickly becoming friends with Alphys due to their shared interest, the two human fanatics came up with an idea that would give them both exactly what they wanted. Alphys would build a body for Mettaton, which would not only allow the ghost to have the physical form they'd always wanted, but also impress Asgore so much, he'd make Alphys the new royal scientist. While everything worked perfectly, the two friends began to drift apart once Mettaton became famous and Alphys became entrenched in her work.

Mettaton NEO was built as a human eradication device, meaning he would likely be able to overpower exceptionally strong humans, the strongest of whom can wield nearly limitless power via their Determination. While Frisk is far stronger than other humans due to their immense Determination, it is not unheard of for stronger humans to reach similar levels, such as the seven humans who formed the barrier.
