The Gorgatron.
Gorgatron is a massive, purple Mooninite who Ignignokt and Err use in their video game to seek the Moon Master for protection from him. Gorgatron has large feet, what appears to be horns ontop of his head, and only one tooth emerging from his lower jaw. The Gorgatron is said quite ferocious. He appears only in Moon Master, and at the end of said episode, Ignignokt and Err are shown trying to sell Moon Master merchandise to him. He is also featured as one of the bosses in Aqua Teen Hunger Force: Zombie Ninja Pro-Am.
