Well, it depends. While Pikachu is an old and well - known Pokemon in the franchise, in fanfiction, it doesn't necessarily mean it's 'too old'. Some fanfiction writers might use Pikachu's long - established character as a base to build new and unique stories. They could explore different aspects of Pikachu's personality, like its loyalty or its mischievous side in more depth. Or they could create alternate universes where Pikachu has different abilities or relationships. So, just because it's been around a long time doesn't automatically make it too old for fanfiction.
It could be a new, young Pokemon who befriends the old Pikachu. This young Pokemon could witness Pikachu's decline and death, and through this experience, learn about the history and importance of Pikachu in the Pokemon world.
The fanfiction could be about how the Pokemon world has changed over time and Pikachu is left behind as an 'old - fashioned' Pokemon. It might face discrimination or neglect because of its age. The death of Pikachu could be a symbol of the end of an era in the Pokemon world. It could also explore how the younger generation of Pokemon and trainers view Pikachu's legacy.
The repetitive storylines. So many stories about Pikachu follow the same pattern: it gets caught by a trainer, battles other Pokemon, and levels up. In fanfiction, this lack of originality can make Pikachu seem old. Writers often find it difficult to break away from these established story patterns, which in turn makes the character seem stale.
One popular type of Pokemon Ash and Pikachu fanfiction might be adventure - based. For example, Ash and Pikachu could embark on a journey to a new and mysterious region filled with undiscovered Pokemon species. They might face challenges like difficult terrains and powerful, previously - unseen Pokemon. In this fanfiction, Pikachu's electric powers could be enhanced in some unique way, and Ash would have to strategize differently to overcome the obstacles.
In this kind of fanfiction, Ash might find it really hard at first. He's used to being a human trainer, and suddenly becoming a Pikachu would be a shock. He'd have to learn how to control Pikachu's electric powers which he only used to command before.
One possible reason could be that Pikachu is separated from Ash. In many fanfictions, their bond is so strong that being apart would be extremely distressing for Pikachu, leading it to cry.
In a fanfiction, Pikachu and Fennekin could be part of a Pokemon rescue team. They save other Pokemon from various disasters such as forest fires or cave - ins. Pikachu uses its speed and electricity to clear obstacles, while Fennekin uses its intelligence and fire to keep everyone warm and scare away predators. This would show their heroic sides and their bond as teammates.
The concept of facing fears is a theme that can be explored. Ash may have fears about not being a good enough trainer, and Pikachu could have fears related to its own power or protecting Ash. Fanfictions can show how they overcome these fears together. Additionally, the theme of legacy could be present. Ash wants to be a great Pokemon master like his idols, and Pikachu is part of that journey. Their story could be seen as part of the greater Pokemon legacy, and fanfictions can play with this idea in different ways.
Maybe in a fanfiction, Pikachu and Fennekin find themselves in a strange, magical forest. They have to rely on each other to find their way out. Pikachu's ability to sense electricity in the air helps them avoid dangerous areas, and Fennekin's sense of smell leads them to sources of food. Their journey through the forest strengthens their bond.
