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.
The plot could start with Ash getting Riolu as his starter Pokémon instead of Pikachu. Riolu might be a bit of a troublemaker at first, not fully understanding Ash's commands. But as they journey together, they start to understand each other better.
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.
One common theme is friendship. Riolu often forms strong bonds with Naruto and other characters, just like in the original Naruto series where friendship is a major aspect.
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.
One idea could be that Ash has a strange encounter in a mysterious forest. There, he finds a Riolu in distress. As he tries to help the Riolu, a strange energy transfer occurs, and he starts to take on some of Riolu's characteristics. He might gain Riolu's heightened senses, like its ability to sense auras more acutely. This could lead to new adventures as he has to adapt to these changes while still trying to pursue his Pokémon journey goals.

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.
