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.
A possible theme could be friendship. Despite their differences, Mewtwo and Lugia could form an unlikely friendship. Mewtwo is a man - made Pokemon with a complex past, while Lugia is a more natural, mythical guardian. Their friendship could show that even very different beings can come together for a common good.
Ash could be one. He has a way of befriending all kinds of Pokémon, and his encounter with a friendly Mewtwo would be an exciting story. He could learn a lot from Mewtwo's psychic powers and wisdom.
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.
It could also be that Mewtwo is misinterpreting the intentions of humans. In the fanfiction, it sees a large - scale Pokemon capture operation as a threat to all Pokemon. So it decides to take matters into its own hands and starts 'hurting' those involved in the operation, which includes both trainers and their Pokemon. But eventually, through communication and understanding, things are resolved.
One possible plot could be that Mewtwo discovers a hidden place where the Unown reside. The Unown, with their mysterious powers, initially seem like a threat to Mewtwo. But as the story unfolds, Mewtwo realizes that they are more complex. Maybe the Unown are trying to protect a powerful secret or an ancient artifact. And Mewtwo has to decide whether to help them or take the power for itself.
In a world where Pokemon coexist with humans, Mewtwo stands apart, a being of both power and mystery. Mewtwo's relationship with other Pokemon is complex. It was created by humans, but it resents its origin. It often isolates itself from the normal Pokemon society. However, there are a few Pokemon that manage to break through Mewtwo's cold exterior. Pikachu, for example, with its innocent and friendly nature, makes Mewtwo question its view on the world of Pokemon. Their interactions start with Mewtwo's initial dismissal, but Pikachu's persistence slowly chips away at Mewtwo's defenses, leading to a unique bond that challenges Mewtwo's understanding of friendship and connection.
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.
A 'pokemon mewtwo and missingno fanfic' could potentially tell a story where Mewtwo, the powerful and genetically - engineered Pokemon, crosses paths with Missingno, the infamous glitch Pokemon. It might be a story of how Mewtwo tries to understand or control Missingno, or perhaps they team up against a common enemy. There could be a lot of creative elements in such a fanfic, like new abilities for the Pokemon or a whole new world created just for them.
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.
I'm not sure specifically as it could be a very niche fanfic. It might be a fan - created story about Lugia that somehow involves balloons. Maybe it could be a story where Lugia is associated with balloon - like powers or there are balloon - themed adventures around Lugia.
