Ash Catches Greninja Fanfiction: What Could the Storyline Be?

When Ash catches Greninja, it might change the dynamics within his team. Greninja could be a bit of a loner at first, not really fitting in with the rest of the Pokémon. But over time, through shared battles and experiences, it could learn to work well with the others and even inspire them to improve.

There could be unfinished business between them. They might have a shared goal that they haven't achieved yet. Greninja's return to Ash in the fanfiction could be to finally complete that goal, whether it's winning a particular Pokemon tournament or saving a certain place from destruction.

One possible plot could be that Ash and Greninja start in a different region than the usual ones. They have to adapt to new Pokémon, new trainers, and new challenges. Along the way, they meet other trainers who are also starting with unique Pokémon, and they form a team to compete in a new kind of Pokémon league. Ash and Greninja would have to learn new battle strategies and overcome their differences to succeed.

They might have an epic battle against a common enemy together. Greninja could show off some new moves it has learned during their separation, and Ash could use his experience from other adventures to lead them to victory.

In this fanfiction, Greninja might come back with new powers. Maybe it has been on a special training journey and returns to Ash to help him in a big battle.

In this fanfiction, Ash might introduce Greninja to his family. His mother could be surprised but also happy to see such a unique Pokémon. Maybe Greninja would show off some of its cool moves in the backyard.

Well, perhaps Greninja will encounter some new and strange Pokémon in Alola that it has never seen before. Ash could use this opportunity to train Greninja further, and they might participate in some Alola - specific Pokémon contests or battles together. Greninja's presence could also stir up some friendly rivalries among the local Pokémon and trainers, leading to exciting adventures and growth for both Ash and Greninja.

In the fanfiction, perhaps Ash catches Dratini during a quest. He hears rumors about a rare Dratini in a certain area. He goes there and finds Dratini being chased by some other Pokemon. Ash steps in to protect it and earns Dratini's trust. The story could then focus on their adventures together, exploring new regions and facing tough opponents with Dratini by his side.

One possible plot could be that Ash is on his Pokémon journey and stumbles upon a Haunter in an old, spooky forest. The Haunter might initially be mischievous, playing tricks on Ash and his Pokémon. But as Ash shows kindness and understanding, the Haunter starts to warm up to him. Eventually, Ash manages to catch the Haunter through a series of exciting battles and challenges, adding a unique and somewhat spooky addition to his Pokémon team.

One possibility is that Ash stumbles upon Meltan in an unexpected place, like a hidden grove. He uses his Pokémon knowledge and skills to gain Meltan's trust and catches it. Maybe he uses Pikachu to show Meltan that they can be friends and partners. This could lead to new adventures as Ash trains Meltan and discovers its unique abilities.
