One possible fanfiction could be about Riolu and Kirlia's adventure in a lemon grove. They might discover a magical lemon that gives them special powers. Riolu could use its fighting skills and Kirlia its psychic abilities to protect the lemon from some villains who want to use it for evil purposes.
In a fanfiction, perhaps there is a world where lemons are a rare and precious resource. Kirlia and Riolu are sent on a mission to retrieve some lemons from a dangerous area. Along the way, they face various challenges and have to rely on each other's strengths. Kirlia's ability to sense things from afar with its psychic powers helps them avoid some traps, and Riolu's combat skills protect them from wild Pokémon. The story could be about their journey and the bond they form during this lemon - related quest.
Riolu and Kirlia could be rivals at first, but then they both become interested in a mysterious lemon that has some sort of energy. They decide to team up to figure out what the lemon is all about. They might enter a competition to win the lemon and along the way, they learn about each other's strengths and weaknesses.
A simple plot could be that a group of Pokémon including Kirlia and Riolu live in a village near a lemon grove. One day, the lemons start to wither for an unknown reason. Kirlia uses its psychic powers to try to figure out what's wrong, and Riolu scouts the area for any signs of trouble. They find out that a dark - type Pokémon is draining the energy from the lemons. So, they team up to defeat this Pokémon and save the lemons.
I'm sorry, but 'lemon' in fanfiction often refers to inappropriate or adult - themed content, so I can't recommend such fanfictions. However, there are many great family - friendly Riolu fanfictions out there that focus on its adventures, growth, and relationships with other Pokémon.
Riolu's ability to sense auras is a very interesting characteristic. In fanfiction, it could be used to detect hidden threats or to understand the emotions of other Pokémon and humans better. For example, a story could be about Riolu using its aura - sensing to find a lost Pokémon in a maze - like forest.
Riolu could start off as a shy and scared Pokemon. But as it spends more time with Ash, it would become more confident. It might learn new moves and become more brave in battles, evolving into Lucario eventually as it gains more experience and trust in itself.
Riolu's personality could develop in a way that it becomes more confident. At first, it might be scared of battles and new situations. But as Ash encourages it and they have small victories, Riolu starts to believe in itself. For example, after winning a small battle against a weak pokemon, Riolu realizes it has the potential to be strong.
Riolu may become more confident. As it transforms, it realizes it has new powers and abilities. For instance, if it gains the ability to sense auras more strongly, it becomes more self - assured in battles and interactions with other Pokemon.
Growth and development is another theme. Baby Riolu is at the start of its journey, so stories might focus on it getting stronger, learning new moves, and evolving. For example, it might struggle at first but through hard work and determination, it overcomes challenges and becomes more powerful.
