The plot could involve a trainer who discovers the pregnant Lugia. The trainer decides to stay and help, using their knowledge of Pokemon care. They gather special items or herbs to assist the birth. This could lead to a unique bond between the trainer and the Lugia family, and perhaps the baby Lugia would later become a special partner for the trainer.
Unique features could include the special birthing place. Maybe it's a hidden cove filled with magical energy that only Lugia can access. This place could have crystals that glow and provide the necessary warmth and power for the birth.
To write a good Pokemon giving - birth fanfiction, focus on emotions. Show the anticipation and nervousness of the pregnant Pokemon. You can also add some conflict, like a villainous team trying to capture the soon - to - be - born Pokemon for their own evil purposes. And don't forget to make the story believable within the context of the Pokemon world. Use the existing lore and rules of the Pokemon universe to ground your story.
One interesting plot could be a story about a rare Pokemon giving birth in a hidden, magical place. Maybe a shiny Eevee is about to give birth and the whole forest of Pokemon comes together to protect it from any potential threats. This shows the unity among Pokemon in such a special event.
A plotline could involve a curse or a strange experiment gone wrong that causes Ash to be in a situation where he has to give birth. Or perhaps there's a parallel universe where the rules of Pokemon are different and male characters can give birth. Ash could be on a journey in this universe and have to deal with this new and unexpected situation, learning about himself and the world around him in a completely different way.
In many fanfictions where Ash catches Lugia, it often involves a great adventure. Maybe Ash stumbles upon Lugia in a hidden cove. Lugia, being a powerful and majestic Pokémon, would be a huge addition to Ash's team. It could change the dynamic of his battles completely. He might have to prove himself worthy to Lugia first, perhaps by showing his kindness and determination in protecting other Pokémon in the area.
It's quite unique. Since Ash is a male character in the Pokemon series, the concept of him giving birth is not something that would occur in the official canon. Fanfiction writers might be using this as a way to be extremely creative and subvert the normal expectations. It could also be a way to explore themes like gender - bending or creating a completely different kind of story within the Pokemon universe that challenges the traditional ideas we have about the characters.
One common theme is empowerment. A female Lugia is often shown as a powerful and independent figure. Another theme could be friendship, like her forming bonds with other Pokemon or trainers.
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.
One idea could be to focus on a rare Pokemon giving birth. For example, a shiny Pokemon. You could explore how the trainers and other Pokemon in the area react to this special event. Maybe they gather around to protect the mother during the process.
