Hunter is a character who first appears in Spyro 2: Gateway to Glimmer. (Birthday 2/24/75 according to the coordinates he suggests in Spyro 2.)
For a cheetah, Hunter is forgetful, happy go lucky and clumsy. This is why, despite being very athletic, he cannot defeat Ripto in Spyro 2. He also appears in later games, as one of Spyro's constant friends.
In Spyro 3, Hunter has a growing crush on Sorceress-in-training, Bianca. Bianca's decision to stop fighting against Spyro, and instead join their side may be partly due to, or at least encouraged, by their growing romance.
In Spyro: A Hero's Tail, Hunter becomes a playable character for the first time.
