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.
A plot might be that Lugia is being hunted by an evil organization. Ash discovers this and decides to protect Lugia. He uses his Pokémon to fight off the bad guys. In the process, he forms a bond with Lugia. Eventually, Lugia realizes that it's safe with Ash and allows itself to be caught. This would show Ash's heroism and his love for Pokémon.
The plot could revolve around the build - up to the birth. There might be some pre - birth challenges like Sakura having to take a break from her ninja duties and Naruto having to take on more responsibilities in the village. Then comes the day of birth. Sakura goes into labor and the whole village is on edge. Naruto is right by her side, and they both experience the joys and pains of bringing a new life into the world.
One possible plot could be that Pikachu is in a Pokémon center being cared for by Nurse Joy. The other Pokémon in the center are all very excited and protective. Pikachu's trainer is by its side, constantly reassuring it. As the time for giving birth approaches, Pikachu becomes a bit nervous but also shows great determination. Finally, it gives birth to a cute little Pichu.
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.
In this fanfic, perhaps there is a prophecy that only Mewtwo and Lugia together can fulfill. The prophecy might be related to saving the Pokemon world from a great disaster, like an approaching asteroid or a dark force that is spreading across the land and sea. They start as strangers, but as they begin to understand the prophecy and their roles in it, they form a deep bond. Mewtwo uses its intelligence and combat skills, and Lugia uses its natural strength and connection to the elements to face the impending doom.
One possible plot could be that the main character, perhaps a female elf or dwarf, finds herself in Mirkwood while pregnant with Thorin's child. She might face challenges like the dark forces in Mirkwood that threaten the safety of her and the unborn baby. The story could involve her seeking shelter and protection from the elves of Mirkwood, who are initially hesitant but then come to her aid due to her connection to Thorin. There could also be a sub - plot about Thorin trying to reach her in Mirkwood, facing his own set of obstacles on the way.
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 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.
