The series has been rebooted several times with the original series being published from 1998 to 2005, the Legend series published between 20, and the Skylanders series published from 2012 to 2015.
Despite featuring Spyro the Dragon and Cynder as playable characters and using Spyro's name in the subtitle of the original game to generate marketing interest, the Skylanders franchise is otherwise completely unrelated and the characters from that franchise are covered in their own section.

Sparx (voiced by André Sogliuzzo in 1998-2004, David Spade in 2006, Billy West in 2007, Wayne Brady in 2008) is a yellow dragonfly and Spyro's constant companion.
He helps protect Spyro from damage, helps collect gems, and gives out helpful information throughout the game.
Sparx was also a playable character in Year of the Dragon, Season of Ice, and A Hero's Tail, with his levels featuring gameplay similar to Gauntlet and rail shooter games.In the Legend of Spyro games, Sparx no longer protects Spyro from damage and instead serves as his traveling companion.In the Skylanders series, Sparx is a living magic item who aids the Skylanders by firing fireballs at enemies for a short while.A cheetah who trains (and sometimes challenges) Spyro with various tasks.While he's a loyal friend and marginally knowledgeable with basic tasks, he seems to have trouble grasping the severity of Spyro's mission and can be relatively naive and gullible, leading him to being captured or tricked easily.Hunter developed a crush on Bianca in Year of the Dragon, and in the same game, had 4 playable minigames of his own, one in each the speedway level, He was a fully playable character in two levels of A Hero's Tail.
