Gyorg was a Lycan mentioned in Underworld: Rise of the Lycans. It is unknown if he is ever seen; he may presumably be seen as a background character, as Peter Tait is listed in the official credits as the credited actor. It can be assumed that he holds a lower rank than the Lycan slave Lucian.
After Lucian removes his collar in order to protect Vampire princess Sonja from an army of Werewolves, he is imprisoned. The Vampire Elder Viktor approaches Sonja for her recommendation on who should replace Lucian, to which Sonja suggests Gyorg. From Viktor's reaction later on, it can be assumed that he holds Gyorg to a high esteem, as he voices his strong consideration of him.
