In some Spyro vs Dark Spyro fanfiction, there might be a plot where Dark Spyro is a manifestation of Spyro's repressed fears and insecurities. So the story could be about Spyro facing his inner demons, literally. For example, Dark Spyro could be causing chaos in the dragon worlds, and Spyro has to figure out how to defeat him without simply destroying the part of himself that Dark Spyro represents.
Perhaps a plot where Dark Spyro is lured into the light by Spyro's unwavering friendship. Spyro could be on a quest to save Dark Spyro from the clutches of a dark force that has corrupted him. Along the way, Spyro discovers new powers within himself that he uses to combat Dark Spyro's dark magic, and eventually, through a series of challenges and self - discovery, he manages to turn Dark Spyro back to his original self.
One idea could be a battle for the control of a powerful magical artifact. Spyro wants to use it for good, like restoring a desolated land, while Dark Spyro sees it as a means to gain ultimate power over the dragon realms.

Then they combine their unique skills, like one Spyro's amazing flying maneuvers and the other's powerful fire breath, to solve a mystery in the dragon world, like the disappearance of an ancient dragon artifact.
The main characters are Spyro and Dark Spyro. Spyro is the character we know from the games, with his unique personality and abilities. Dark Spyro is a more complex character. He might not be completely evil but rather a product of some external influence that has made him turn against Spyro.
