Mettaton from the 2015 PC game Undertale. It is an entertainment robot designed, built and programmed by Dr. Alphys. However, Alphys admits that during Mettaton's programming she added anti-human software to it, and now he's a murderous machine, as he constantly traps the protagonist Frisk. Mettaton also happens to be the first machine to be given a soul, the soul of the ghost Hapstablook.
