Bully Nerd is a drawing created by Rudy Tabootie that was based on his school bully Reggie Bullnerd. Rudy initially made him to act as a main villain to Snap in his drawings which represented his own dislike of Reggie. After having had enough of Reggie's bullying, Rudy drew Bully Nerd and Snap on the chalkboard for all to see, however the chalk drawings were soon erased by his teacher and given life in ChalkZone where Bully Nerd would continue to antagonize Snap like in the drawings.
