Mettaton is outgoing, confident, and an absolute drama queen. Slightly sadistic in nature and willing to do just about anything to gain fame and recognition. Great at dancing and not afraid to kick anyone who gets too close during a mood swing. Has a pretty great voice too and isn't afraid to show it off.

Has physical ability to back up attitude and not afraid to use strength or power to overcome anyone who stands in the way. Speaks in a proper manner and may come across as being flirtatious when he just simply sees himself as being glamorous.
