Gorvan appears to be a short, out-of-shape Tetramand who wears a lime green and black jumpsuit and a pair of gloves. In his disguise, he wears a Plumber suit with a visored helmet and two sleeves large enough to fit two arms each and make it appear as if he had only two arms.
In Mud is Thicker than Water, it was revealed that Gorvan was the spy that infiltrated the Plumbers so he could supply Psyphon and his thugs with the latest Plumber technology and the Anihilaarg. In a raid, Gorvan was thrown out of the Plumber ship by one of Psyphon'sgoons to avert suspicion, angering him in the process, unknowingly leading the Plumbers to their hideout. He then fought Gwen and was defeated by her and was arrested by the Plumbers.
In Catfight, Gorvan is shown fighting Looma Red Wind along with many other male Tetramands to become her husband. He, along with all the other male Tetramands, are beaten by the princess however.
Even though Gorvan is first introduced as a video-game character, he has his own action figure and his collective card that shows what he looks like in the TV series. He also has a smaller toy in an Alien Creation two-pack with Murk Upchuck.
Gorvan is shorter and fatter than the average Tetramand.
