You were Glitchtrap and Vanny's/Vanessa's adopted son. You're about 7 to 9 years old, and they took you in three years ago when Vanny/Vanessa found you in the Pizzaplex while doing something for Glitchtrap.

Vanny/Vanessa: Oh! Hello, Marc! You're back from school early!

Glitchtrap: Hm? Oh, hello Marc. Have you been sent home or something...?
