Communication is key. If in the fanfiction, Manaphy is able to communicate more effectively with Ash and May, they can share their dreams, fears and hopes. This emotional connection would deepen their relationship. For instance, Manaphy could tell them about its longing to see its family in the ocean, and Ash and May could vow to help it.
They can develop their relationships through shared adventures. For example, when facing a difficult battle together, they learn to trust and rely on each other. Ash's determination, May's knowledge of Pokemon, and Manaphy's special powers can complement each other in battles, which deepens their bond.
A 'ash may manaphy fanfic' might center around the relationship between Ash, May and the mythical Pokémon Manaphy. It could be a story that takes place in the Pokémon world where they form a team to solve some mystery related to Manaphy, like finding its lost home or something.
Ash might develop a deeper sense of responsibility. In a fanfiction, if he is in charge of protecting Manaphy, he would have to think more about the consequences of his actions. He could also learn to be more diplomatic, especially when dealing with May's different approach to Pokémon. May could grow in her ability to adapt. For example, if they end up in a situation where there are no contests but only battles, she could learn from Ash how to handle it. Manaphy could develop its psychic abilities further. Maybe it discovers new powers within itself while being with Ash and May, and they help it to control and use these powers for good.
Ash, being the protagonist in many Pokémon stories, is a key character. May, his friend and fellow Pokémon enthusiast, is also important. As for the Manaphy family, Manaphy is the central figure among them. It could be a story where a Manaphy is born and Ash and May are there to witness and protect it. So the baby Manaphy and its parents, if they are part of the story, are also main characters in this fanfiction.
Some writers portray Manaphy as a very innocent and curious creature. It might be constantly exploring its surroundings, getting into small amounts of trouble that Ash and Lillie then have to help it out of. For example, it could be attracted to shiny objects and accidentally get stuck in a cave while trying to reach one.

One way is through shared experiences. If they go on a journey together, facing challenges like crossing a dangerous mountain or surviving in a harsh environment, their bond will strengthen. Ash can also show kindness to Houndoom, like sharing his food or finding a comfortable place for it to rest. This will make Houndoom trust Ash more and deepen their relationship. Another aspect could be that Ash learns to understand Houndoom's unique personality traits. Maybe Houndoom is a bit shy at first but has a very loyal side. As Ash discovers these things, their relationship will evolve.
