Monster Chuck first appeared in the episode Indie Road Rager where he was competing in the Indie 400 with a monster truck that was twice the size of a normal monster truck. Trina made Mina overinflate the wheels of his truck to make it float in the air and then pop the wheels by shooting arrows at them which made it crash on the ground. When Monster Chuck found out about this, Trina told him that Grojband did this to his truck which made him very angry at them. In the race, he got his truck repaired and was more determined to destroy Grojband in the race than he was to win the race. During the race, he pulled out a missile launcher and fired missiles at them but he missed every time he fired at them. During the song, Trina climbed up into his truck, opened the window and threw him out of the vehicle and onto the street so that she could take the wheel of his truck and then she drove off with it and chased after Grojband. While Corey played a guitar solo, Laney threw Mr. Mooseface at the windshield of Monster Chuck's monster truck which caused Trina to wildly spin out of control and fall off the tracks where the truck blew up in a fiery explosion just before his truck could reach the finish line.
In the episode "Ahead of our own Tone," Monster Chuck was seen waiting in line to get the new Blab Tap.
