Despite appearing overweight, Gorvan has highly enhanced strength and agility due to the nature of his species. He is also in possession of a machine which refills his stamina.
Ben first meets Gorvan where he was fighting a group of Forever Knights, where he is after a mysterious component. Gorvan enlists Ben, Gwen and Kevin's help to find the rest of the components. He claims to be a Plumber and even knew Max Tennyson.
Secretly, Gorvan was working for the Highbreed and is on the run from the Plumbers. He tricked the trio into invading a Forever Knight's castle and fighting Vulkanus and his pick-axe aliens for another component.
Gorvan turned Kevin into a DNAlien and made him fight Ben, but luckily, Ben was able to defeat Kevin and change him back to normal, Gorvan then fights Ben, and used a rejuvenation machine to increase his stamina. Ben was still able to defeat him though and kept Gorvan captive with some holding-cells. It is unknown what happened to him after the game was over, though it seemed simple that he was put into Plumbers' captivity.
Gorvan admits he could stand to lose a little weight.
Gorvan is shorter than average for a Tetramand.
Gorvan is one of the few Plumbers to have gone rogue and become a criminal. Before going rogue, he held the rank of Magister, making him currently the only known Magister to have gone rogue.
