Sperg is the local bully at Billy and Mandy's school and their neighborhood. He is often seen tormenting Billy, Irwin, Pud'n (or all three), or other kids to no end. However, Sperg is afraid of Mandy due to her cynical attitude.

In "The Most Greatest Love Story Told Ever," Sperg melts when punch (the drink) is thrown right at him in the fight. In "Battle of the Bands," Sperg was the frontman (lead vocals / lead guitar) until Grim proved that he can join the band and Sperg changed to rhythm guitar while Grim took his place. His head blew up in "Billy and Mandy Moon the Moon."

He is voiced by Greg Eagles.


He is overweight, wears a dark green shirt, blue jeans, white shoes, and a red hat. In the Battle of the Bands episode, he wore a hat with a spike, and had reddish hair, like Billy's. He has a heart-shaped tattoo that reads: "MOM" on his arm, and he's usually seen wearing a red beanie with a red puffball on top.


Sperg is an 11-year-old boy whose preferred method of terrorizing nerds is by administering his "lethal" wedgies.

Sperg is extremely defensive of his mother. Even though he has brutal strength, Sperg is scared of Mandy because she's stronger than him. Sperg's life-long dream when he gets older is to become a dancer and singer on Broadway. Deep down Sperg is lonely. All Sperg really wants is a friend. Sperg tends to be very emotionally sensitive, though he tends to keep this side of him under wraps.
