She could also be a bit mysterious. For instance, she might have some unique abilities that are not known to most Pokémon or humans. This mystery would draw Ash closer to her as he tries to figure out more about her and her powers.
One possible plot could be that Ash encounters a female Lugia in a new and unexplored region. The Lugia is in trouble, perhaps being hunted by an evil organization. Ash decides to help it, and in the process, they form a unique bond. They go on adventures together, with Ash learning new things about Lugia's powers and how to communicate with it better.
You can try looking on fanfiction websites like FanFiction.net or Archive of Our Own. These platforms have a wide range of fan - created stories, including ones involving Ash and a female Lugia. Just use their search functions to look for relevant titles or tags.
A theme of discovery might be present. Ash is constantly exploring the Pokémon world, and with Female Lugia by his side, they could discover new Pokémon species, new lands, or new powers. The 'lemon' part could add a layer of emotional discovery as they learn about their feelings for each other during their adventures.
One possibility could be an adventure plot where Ash and Female Lugia team up. Maybe they're on a quest to save a certain region from an environmental disaster. The 'lemon' aspect might be a very mild romantic sub - plot where they develop a special bond, like sharing moments of mutual understanding and support during their journey.
Another theme is the concept of power and responsibility. Lugia is a very powerful Pokémon, and when Ash is associated with it, there's often a story arc about how they use that power in a responsible way, whether it's to protect the Pokémon world or to deal with some sort of imbalance in the ecosystem.
It could be about Ash, a character, catching Lugia in a fan - created fictional story. Maybe it details his adventure in finding Lugia, the challenges he faces during the catch, and how this event might change his journey in the Pokémon world.
In a fanfiction scenario, Ash might be in a situation where he has to use a unique Pokeball to catch Lugia. The Pokeball could have some sort of special power, like being able to withstand Lugia's powerful attacks. Ash would have to figure out how to use this Pokeball effectively while also respecting Lugia's might and the bond that Lugia has with the sea.
Another storyline could involve a female Lugia being in trouble because some evil Pokémon trainers are trying to capture it for its power. Ash hears about this and teams up with his friends to protect the Lugia. Along the way, they face many challenges and Ash has to use his battle skills and knowledge of Pokémon to outwit the villains.
Ash's personality could shift to be more protective. Lugia is known as a guardian of the seas, and in his transformed state, Ash might feel a stronger sense of responsibility towards other Pokemon and the environment. His competitive streak, which is a big part of his normal personality, could be toned down as he now has much greater power and a different role to play in the Pokemon world. He would also have to deal with the isolation that comes with being such a powerful and different being, which could make him a bit more introverted.
In 'Ash becomes a Lugia' fanfiction, a recurring theme is the clash between Ash's human nature and his new Pokémon form. His human emotions like determination, loyalty, and compassion are still there but are expressed differently as Lugia. Another theme is the exploration of the Pokémon lore. Since Lugia is a very important and mysterious Pokémon, the fanfiction may dig deeper into the myths and legends surrounding it. Additionally, the theme of growth is present. Ash grows not only in terms of power but also in his understanding of the Pokémon universe as he becomes Lugia.
