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 popular Ash and Ash - Greninja fanfiction could be those that focus on their adventures in a new, unexplored region. In these stories, they might face unique and powerful Pokémon, strengthening their bond along the way.
Well, in Alola, the battle environment is different. Ash Greninja has to adapt to the new battle rules like Z - Moves. It may start by observing local battles and learning from them. It could also adapt to the more friendly and less intense battle atmosphere compared to other regions. This means it might have to change its battle strategy a bit, not always going all - out from the start. And it might interact with different types of Pokemon that are native to Alola, which could lead to new friendships or rivalries, further shaping its adaptation to the Alola environment.
I'm not a big fan of yaoi fanfiction in general, but in the case of Greninja and Ash, it often involves a creative exploration of their relationship in a non - canonical way. Some of these fanfictions might focus on their strong bond and translate it into a more romantic or emotional connection that goes beyond friendship as seen in the original Pokemon series.
Well, it could vary a great deal. In some 'ash greninja returns fanfiction', it might focus on Ash and Greninja reuniting after a long separation. Maybe Greninja has been in a far - off place training or on a mission, and now it comes back to Ash to help him in a big battle. They then team up again, with Greninja using its unique Water - Shuriken and other moves to take on powerful opponents.
One common theme is friendship. Ash and Greninja's relationship is often at the center, showing how they rely on each other and grow together. For example, in many stories, they face challenges that test their bond and come out stronger.
In a fanfiction, Ash and Greninja might face a powerful, new villain. Greninja, as Ash's starter, could have some unique abilities that are crucial in the battle. For example, Greninja might discover a new form that is only possible because of their deep connection, which was formed from the very start of their adventure together.
A great fanfiction idea could be that Greninja has a hidden power that only Ash can unlock. As they travel together, they encounter a series of increasingly difficult battles. In one crucial battle, Ash's belief in Greninja is what finally unlocks this power, leading to an epic victory.
Social media groups dedicated to Pokémon fanfiction can also be a great place to look. For example, on Facebook or Reddit, there are groups where fans post their works or recommend good fanfictions. So, search for relevant groups and look for the 'Ash starts with Greninja' fanfictions there.
