Monster Kid or MK is a child Monster that lives in Snowdin Town in the Underground. He arrived there after he was found by Sans and The Shadowy Figure in the CORE while they were there to collect something. After collecting what they were going to, they brought him back to Snowdin with them. Because they didn't know his name, and because he couldn't tell them his name, The Shadowy Figure just started calling him the Monster Kid, or just MK for short.
MK is the type of person who obsesses over certain people, wanting to imitate the selected person completely.
