Rather than seeking such potentially inappropriate fanfiction, you could look for more family - friendly Kirlia fanfiction on official Pokémon fanfiction platforms. They usually have a wide range of stories that focus on adventure, friendship, and the growth of the Pokémon.
The potential for different storylines. As I mentioned before, they could be on an adventure, training, or uncovering secrets. All these storylines can keep the readers engaged. For example, if they are on an adventure, the readers will be eager to know what new places they will visit and what Pokemon they will meet. If it's about training, we can see the Riolu grow and develop new abilities, which is always exciting in the Pokemon universe.
Another possibility is that the shiny Riolu has some special powers that Ash discovers. They could be related to a hidden legend in the Pokemon world. Ash and the Riolu then have to protect this secret from those who would use it for evil. They might travel to ancient ruins and encounter other mysterious Pokemon on this journey.
Well, another option could be to check out Pokémon - related forums. Sometimes fans share their fanfictions there. Maybe look for ones that focus on Ash's adventures and specifically mention Riolu. There could be some hidden gems in those communities.
Perhaps the fanfiction could have a plot where Ash discovers a Riolu with some special abilities. He has to protect Riolu from those who want to use its powers for bad. This could lead to an adventure filled with battles and new friendships for Ash and Riolu. It might also explore the bond between Ash and Riolu as they grow together. Ash could learn new training techniques from Riolu's unique skills, and Riolu could learn about trust and friendship from Ash. There could be a big showdown at the end against an evil organization that wants to capture Riolu.
The main character would be Ash in his Riolu form. Professor Oak could be in the fanfiction. He would be very interested in studying Ash's transformation. Another potential character could be May. She could come across Ash as a Riolu during her travels and offer her help. Also, some wild Pokémon that Riolu typically interacts with, like Growlithe or Pidgey, could be part of the story, adding more elements to Ash's new Riolu - centric adventures.
A good Pokemon Kirlia fanfic often has well - developed characters. It should give Kirlia a distinct personality, not just make it a generic Pokemon. For example, it could show Kirlia's growth and development in terms of its powers and relationships with other Pokemon or trainers.
Well, social media groups dedicated to Pokemon can also be a great source. For example, on Facebook or Reddit, there are groups where fans discuss all aspects of Pokemon, including fanfics about Kirlia. You could post a request asking for good Kirlia fanfics and I'm sure you'll get some great suggestions.
