An old and experienced dragon slayer who has seen many battles and has a lot of wisdom to pass on. He could be a mentor figure to the younger slayers, but also has his own secrets and past traumas related to the dragons that could be explored.
One idea could be that the dragon slayers discover the dragons they are slaying are actually being controlled by an even greater evil. So they have to team up with some of the dragons to defeat this new threat.
One common reason could be a curse. Maybe they unknowingly violated some ancient rule or pact while slaying dragons, and as a result, a curse is placed upon them that gradually transforms them into the very creatures they hunt. For example, they might have desecrated a dragon's lair that was protected by a powerful magic.
In many fanfictions, it might be a metaphorical transformation. The dragon slayers start to exhibit dragon - like behaviors such as becoming more territorial or hoarding things, which symbolizes their inner change. They could also be influenced by dragon magic in a way that their physical form changes. This concept often adds a new layer of depth to the story, exploring the idea of how the hunter can become the hunted.
One interesting dragon slayers fanfiction could be about a young dragon slayer who discovers a hidden power within themselves. For example, they might find that they can communicate with dragons instead of just slaying them, which completely changes their view of the world and their mission.
A possible origin in the fanfiction world could be an ancient prophecy. Maybe there was always a hidden prophecy that said dragon slayers would one day turn into the very creatures they hunted. This would add an element of fate to the story. Another idea is that it could be part of a dark ritual. The slayers unknowingly perform a ritual during their battles that slowly turns them into dragons.

Well, first of all, they would be more curious. Instead of just focusing on their missions or fighting dragons, they'd be interested in everything around them. The once fearless Dragon Slayers might be a bit more timid as kids, especially when faced with things that are new or a bit scary. Their competitive streaks might also show in different ways, like competing to see who could climb a tree the fastest instead of who could defeat the most powerful enemy. And they'd be more likely to show their feelings openly, whether it's affection for their friends or sadness when they're scolded.
In this fanfiction scenario, the 7 Dragon Slayers as kids would probably form really cute friendships. They'd be more naive and might make mistakes that they wouldn't as adults. For example, they could get into trouble trying to steal cookies from a bakery because they're so hungry. Their dragon - related powers could also be affected. If they were Fire Dragon Slayers, they might accidentally set their own clothes on fire while playing with matches, thinking it was a fun game.
