One possible fanfiction could be about Ignitus' early days as a dragon. Maybe he was a young and curious dragon, just starting to discover his powers. He could have adventures in the Dragon Realms, making friends and facing small challenges that would later shape him into the great dragon we know. For example, he might encounter a group of friendly creatures who teach him about the different elements in their world.
One common theme is empowerment. The female Spyro character often has to overcome challenges and prove herself in a male - dominated dragon world. Another theme is friendship. She might make new friends or rely on existing ones to achieve her goals. For example, teaming up with other dragons or magical creatures. And exploration is also a theme. Discovering new lands or secrets within the Spyro universe.
Spyro is obviously the main character. Then there could be characters like Sparx, his dragonfly friend, who might play a role in the harem dynamic. Also, there could be female dragon characters created specifically for the harem idea, each with their own unique personalities and abilities.
Malefor could be a great antagonist. If Spyro's transformation is related to dark magic, Malefor might try to manipulate Spyro in his new form to serve his evil purposes. He could see Spyro's transformation as an opportunity to turn him against his friends and the Dragon Realms.
Obviously, Spyro and Ignitus are the main characters. Spyro is the young and brave purple dragon. Ignitus is an older and wiser dragon who often guides Spyro. There could also be other dragons like Cynder who might play important secondary roles, or some of the villains from the Spyro universe such as Malefor.
A fanfiction could involve Ignitus training Spyro. He might teach Spyro how to control his fire breath more effectively or how to fly faster. This training could be filled with both challenges and fun moments between the two dragons.
Well, some Spyro the Dragon fanfiction might involve Spyro going on a quest to find a lost dragon artifact. This artifact could hold the key to saving his dragon friends who have been captured by an evil force. And then there are those fanfictions that explore the relationships between Spyro and the other characters in more depth, such as his friendship with Sparx and how it developed over time. Some might also be about Spyro having to face his own fears and insecurities in a more personal journey.
Well, the human could have a really unique adventure. They might befriend Spyro and help him on his quests. Maybe they'd introduce new skills or ways of thinking to the dragon world. For example, humans are good at building complex structures, so they could help build something in Spyro's world to defend against enemies.
The dragon abilities in such fanfiction are described in various ways. For flying, it could be like an extension of the body, as natural as walking for a human. The wings are like sails catching the wind, propelling the dragon upwards and forwards. When it comes to breathing fire, it might be related to the dragon's inner energy or magic. It could start as a small spark in the dragon's throat and then build up into a huge, roaring flame. And the dragon's enhanced senses, like its acute hearing and sharp eyesight, are described as being far superior to that of a human, allowing it to detect prey or danger from far away.
