Cinderblock is a villain who first debuted in Staff Meeting.
In Staff Meeting, he appeared when Robin was fighting him, but Robin was very depressed over the loss of his staff, so he wasn't very effective in hurting Cinderblock because of it. Annoyed, Cinderblock eventually punched Robin, sending him flying.
In Artful Dodgers, he goes in a dodgeball team called the BlockHeads, but is defeated by Robin later.
In Starfire The Terrible, Cinderblock is in a giant area, destroying trains. Robin then defeats him with his motorcycle.
In Man Person, Cinderblock is facing a battle against the Titans, and Beast Boy insists on fighting, but gets hit by his punch. Cinderblock's hand is later seen on Beast Boy's face after the collision.
In Vegetables, Cinderblock is used as a test dummy to show the Titans what they could do if they ate vegetables.
