A crossover with 'Alice in Wonderland' could also be cool. Spyro finds himself in Wonderland and has to navigate through the strange and magical places. He could team up with Alice to defeat the Queen of Hearts who has somehow gotten her hands on a powerful magic item from Spyro's world and is using it to cause chaos in Wonderland.
One idea could be a crossover with another fantasy world like 'The Elder Scrolls'. Spyro could find himself in Skyrim, facing dragons of a different kind. Another could be a crossover with 'Harry Potter', where Spyro enters the wizarding world and has to deal with magic there. Maybe he helps Hogwarts students in a dragon - related task.
One idea could be Dark Spyro's struggle to control his newfound powers. Maybe he accidentally causes harm to those he cares about and has to find a way to master his abilities to protect them.
Another plot could involve Spyro and Link from The Legend of Zelda. Spyro could end up in Hyrule. Link, being the hero, initially is cautious of Spyro. But when they realize they both have a common enemy - Ganon who wants to use Spyro's powers for his own dark purposes, they join forces. Spyro can help Link reach places he couldn't before with his flying, and Link can use his swordsmanship and knowledge of Hyrule to guide Spyro.
One idea could be Spyro discovers a hidden power within himself that allows him to communicate with ancient dragons long thought to be extinct. This new power could lead him on a quest to find a lost dragon realm and restore its former glory.
Well, a great plot for Legend of Spyro fanfiction might be Spyro losing his powers for a time. This would force him to rely on his wits and the help of his friends more than ever. He could go on a quest to find out why he lost his powers and in the process, discover a long - hidden secret about his family or the dragon race. It could also be interesting to have Spyro face a moral dilemma, like whether to save a group of dragons who have done bad things in the past but are now in danger.
Perhaps the vikings of Berk accidentally open a portal to Spyro's realm while exploring a new area. Spyro is intrigued by the vikings and their relationship with dragons. Meanwhile, Hiccup tries to understand Spyro's abilities and how they can be used to improve Berk's defenses. They could team up to rescue some baby dragons that were captured by an evil force from both their worlds.
One idea could be an OC (Original Character) who is a long - lost relative of Spyro. This OC could have unique powers that complement Spyro's.

Their journey could involve them teaming up to face a new, powerful enemy that neither could defeat alone.
Well, a great plot for a Spyro and Fairy Tail crossover fanfic could involve Spyro's dragon powers being mistaken for a new type of lost magic in the Fairy Tail world.

He could end up sharing some of his dragon skills with the mages, like his fire - breathing ability, which could be enhanced by Fairy Tail's magic, creating a whole new kind of power.
