One way is through shared goals. For example, if there is a powerful and evil Pokemon causing trouble in the region. Ash wants to stop it for the sake of the Pokemon and people, and Victini wants to stop it because it threatens the balance of the Pokemon world. As they work towards this goal, they learn about each other's strengths and weaknesses. Ash might learn that Victini is afraid of certain types of attacks, and he protects it. In return, Victini uses its victory power to give Ash's Pokemon an advantage in battles. This mutual reliance and protection deepens their relationship.

One idea could be that Ash and Victini team up to save a special forest that is being threatened by a dark - type Pokemon. Victini uses its power of victory to boost Ash's Pokemon in battles against the dark - type's minions. Another plot could be Victini getting lost and Ash helping it find its way back home while facing various challenges together. They might also encounter a rare and powerful Pokemon that only Victini can communicate with, and they have to figure out how to work with it to solve a mystery in the Pokemon world.
Obviously, Ash would be one of the main characters, since he's the one turning into Victini. Pikachu would also be important as Ash's most loyal Pokémon. And Victini itself could be a key character, either as a part of Ash now or as an entity that helps Ash understand his new form.
Maybe Tracey. He was also an acquaintance of Ash. Since Tracey has his own unique skills and knowledge about Pokemon, his presence could bring new elements to the story. He could help Ash and other friends with things like Pokemon research or understanding some rare Pokemon behaviors.
One possible analysis could be the exploration of the encounter between Ash and Giovanni in the fanfiction. It might focus on the clash of their different goals. Ash, being the determined Pokémon trainer aiming for the top, and Giovanni, the leader of Team Rocket with his own motives. Their meeting could lead to various scenarios, like a battle of wits or an unexpected alliance, which makes the fanfiction interesting.
