Mark is a minor antagonist, first appearing in the episode; Hammer & Fail (Part 1, Rival Builders). He is seemingly the opposite version of the character Matt.
He carries a resemblance to Matt, the difference being, Mark has blond hair and a turtleneck instead of a hoodie. He also has a butt-chin instead of Matt's square one. He does not have a green overcoat either.

- He appears five times, and is with the Zombehs most the time, but doesn't get transformed into one. This is likely because the gang's car splashed blood on his clothes, almost looking like a Zombeh.
- In PowerEdd on Edd's flashback, it was revealed that when Mark was a child, he used to wear glasses and have a square chin like Matt.
