One major factor is the emotional depth that can be added in fanfiction. Fans can really get into the minds of Sir Aaron and Lucario. They can write about Lucario's feelings of loyalty and love towards Sir Aaron in a more detailed way than what the games or anime might show. And for Sir Aaron, his motives, his thoughts about Lucario, and his role in the Pokemon world can all be explored more deeply. This emotional exploration is very appealing to the fans of the Pokemon series.
One of the most interesting aspects of fanfiction involving Sir Aaron and Lucario is the exploration of their deep bond. In many of these stories, the loyalty of Lucario towards Sir Aaron is further delved into. It often showcases how their connection transcends the normal trainer - Pokémon relationship. For example, some fanfics might depict Lucario being able to sense Sir Aaron's presence even from great distances or across different dimensions. This adds a layer of mystery and magic to their relationship that is really appealing to fans of the Pokemon franchise.
In Pokemon fanfiction, Sir Aaron may be a key to unlocking ancient mysteries. His knowledge and experience make him a valuable asset in stories that delve into the forgotten lore of the Pokemon world. For instance, he might know about a hidden temple or a powerful Pokemon that has been lost to time.
Sir Aaron's character might be developed through flashbacks. We could see his past deeds, his kindness towards Pokémon, and how he was misunderstood by some. His relationship with Lucario could be shown as a way to redeem himself in the eyes of the Pokémon world, and this would shape his character further.
One interesting storyline could be Lucario trying to understand the legacy of Sir Aaron. Maybe Lucario discovers an old diary of Sir Aaron's that reveals his secrets and unfulfilled quests. Lucario then decides to embark on a journey to complete what Sir Aaron left undone.
Well, it could be about Ash somehow encountering and catching Sir Aaron's Lucario. Maybe it involves Ash going on an adventure in a place related to Sir Aaron, and through a series of events, he manages to befriend and catch the Lucario. It might also include elements of the special bond that Sir Aaron had with his Lucario and how Ash now takes on that relationship in his own way.
In some fanfictions, Dawn could also be paired with Sir Aaron. Dawn is a strong trainer in her own right. Her presence with Sir Aaron could lead to stories about her getting mentored by him or them going on an adventure together to discover new Pokemon species.

Ash is often portrayed as his usual enthusiastic and determined self. He's eager to learn from Sir Aaron and is always ready for a new adventure. His love for Pokémon shines through even more in these fanfictions.
In Pokemon fanfiction, the claim that Sir Aaron is Ash's father is often a product of the creative minds of fans. Fanfiction allows for a lot of speculation and alternative storylines. There could be fanfictions where they base this on some kind of time - travel or reincarnation theory, or just a simple connection they make between the two characters' personalities or abilities. But the official Pokemon story has no connection between them, and these fan ideas are just for the enjoyment of those who like to explore different scenarios.
