Some Lucario fanfictions are set in alternate universes. In one such story, Lucario might be a part of a detective agency in a steampunk - like world. It uses its psychic abilities to solve mysteries and crimes, and has to deal with corrupt officials and powerful criminal organizations. This type of fanfiction gives a fresh take on the character of Lucario.
One interesting aspect could be how they communicate. Since Lucario can sense emotions and thoughts to some extent, in fanfiction it might be depicted as having in - depth conversations with Ash. Maybe they share their dreams or fears, which makes for an engaging read as it gives a new dimension to their relationship.
A possible plot could involve a dark force threatening both the world of Lucario and Equestria. A group of ponies and Lucario have to come together. The ponies use their magic and the Lucario use their combat skills and aura powers to fight off the common enemy. This would show how different abilities can be combined in a crossover story.
One great Pikachu and Lucario fanfiction could be about their adventures in a new, uncharted region. Maybe they team up to face a powerful and mysterious new Pokémon that threatens the balance of the Pokémon world. In this story, Pikachu's electric attacks and Lucario's aura - based moves combine in creative ways to defeat their foes.
One idea is that the female Lucario has a special connection to an ancient Pokemon artifact. She has to protect it from evil forces that want to use it for their own gain. Along the way, she meets new friends and overcomes many obstacles.
One popular 'lucario loves ash fanfiction' might be 'Lucario's Devotion'. In this story, Lucario's love for Ash is shown through its constant protection of him during battles. Another could be 'The Bond of Lucario and Ash' which delves into how their relationship grows over time.
One possible plot could be that Naruto discovers a strange portal during one of his missions and ends up in the world where female Lucario exists. They initially have a misunderstanding and fight, but then realize they can help each other. Naruto could teach Lucario about the concept of friendship like he has with his comrades in his own world, and Lucario could teach Naruto some unique combat skills that are different from the ninja arts.
The idea of a relationship between them is also interesting because they come from different evolutionary lines. Lucario evolves from Riolu and Zoroark doesn't have a pre - evolution that is directly related in the same way. This gives writers a chance to explore how two such different Pokémon could come to love each other. Maybe it starts with a misunderstanding, like Lucario misinterpreting Zoroark's illusions, and then slowly develops into something more.
A family - friendly Lucario story could be about how it helps out in a Pokémon - themed park. Lucario might assist in guiding lost children to their parents using its sense of direction and its friendly nature to comfort the kids.
One plot idea could be Lucario's journey of self - discovery during pregnancy. It could explore how it copes with the physical and emotional changes, and how it interacts with its friends and allies in this new state. Maybe it has to overcome some challenges while still protecting its unborn.
One possible plot could be that Lucario, with its aura - sensing abilities, detects a strange magical disturbance in the Fairy Tail world. It travels there and teams up with Natsu. Lucario's combat skills and ability to sense opponents' moves before they happen would be a great asset in battles against powerful dark mages. Together, they embark on a journey to find the source of the disturbance and end up uncovering a conspiracy that threatens both the Pokémon world and the Fairy Tail world.
