A great fanfiction could revolve around the origin of the Swap Force. You could explore how the concept of swapping parts came to be in the Skylanders world. Maybe it was a result of an ancient magic experiment gone wrong or right, and how this ability has shaped the battles and relationships in Skylands.
You could write a fanfiction where the Swap Force has to team up with their arch - enemies to face a common, greater threat. This could lead to some really interesting character development, like a villain realizing there's more to life than causing chaos, or a Skylander learning that not all enemies are completely bad. There could be a lot of tension and conflict within the team as they try to work together despite their differences.
Another popular character is Stealth Elf. Her agility and stealth skills can add an element of mystery and excitement to a fanfiction. You could write about her secret missions or her training of other Skylanders in the art of stealth.
Perhaps the Skylanders enter the Naruto universe. They could be mistaken for some kind of new ninja jutsu or summoned creatures at first. Then, they work together with the ninja to protect Konoha from a major threat, like an invasion of powerful demons. The Skylanders' different abilities, such as Spyro's fire - breathing or Stealth Elf's stealth, would add new elements to the battles in the Naruto world.
One idea could be a story where a young Skylander discovers a hidden dragon egg. The Skylander then has to protect the egg from the evil forces in Skylands who want to use the dragon for their own dark purposes. As the egg hatches, a bond forms between the Skylander and the dragon, and they go on adventures together to stop the villains.
One idea could be to have characters from different Skylanders groups team up to face a new, super - powerful villain. For example, the Trap Masters and the Giants could combine their forces.
One idea could be Dark Spyro's struggle to control his dark powers while trying to protect his friends. Maybe he has to face an ancient evil that only his dark powers can defeat, but using them risks corrupting him completely.
One idea could be that Stealth Elf and Spyro team up to face a new and powerful enemy in Skylands. They could use their unique abilities, like Stealth Elf's stealth and acrobatic skills combined with Spyro's fire - breathing and flying, to outwit the foe.
A really interesting plot could be that Spyro and Cynder accidentally swap powers. This would lead to a lot of comical and also challenging situations as they try to figure out how to use each other's abilities and also deal with the villains who take advantage of their confusion. They would have to rely on their friendship and understanding of each other more than ever.
One idea could be Dark Spyro struggling to control his dark powers while trying to fit in at the academy. He might accidentally cause chaos during training sessions.
Another plot could involve Cynder getting lost in a mysterious part of Skylands. Spyro then has to search for her while facing various challenges. As he looks for her, he discovers that Cynder has a special connection to an ancient prophecy. The two of them then must work together to fulfill the prophecy and save Skylands from a great danger.
A plot could revolve around Spyro and Cynder having to train a group of new Skylanders recruits at the academy. They have to use their unique skills and teamwork to get the recruits up to par. This could involve teaching combat skills, as well as lessons about loyalty and friendship within the Skylanders community.
