The Legend of Spyro

From the introduction:

All is not well one night in the Dragon Realms as the evil dragon, Malefor, sends his Dark Armies to lay siege to the Dragon Temple. Upon breaking into the innermost sanctum they smash the eggs to prevent the prophesied birth of the new purple dragon, but are thwarted by the Fire Guardian, Ignitus. Setting the egg adrift on the Silver River, it eventually comes to rest in a nook where a clan of dragonflies discover it. Two of their number adopt the little hatchling and raise him alongside his insect brother, Sparx. The hatchling’s name is Spyro, who grows up believing himself to be a dragonfly, just like his parents, despite his... physique.
