Gnasty Gnorc is one of the antagonist characters from the Spyro game series. He served as the main antagonist in the first Spyro game, but became one of the supporting villains in Spyro: A Hero's Tail.
His name is pronounced as "Nasty Norc," without the Gs. However, the interviewer at the start of the first game (and the scene where Spyro defeats Gnasty Gnorc) mispronounces the Gs as "Guh-Nasty Guh-Norc."
As the first major villain Spyro defeats, Gnasty is referenced in nearly every game in the series.
