In fanfics, Pikachu's Force Lightning can be depicted in various ways. Some might show it as an extremely powerful attack that can even take down much larger and stronger Pokemon. It could be a result of Pikachu reaching a new level of power or being in a special state of rage or determination.
Well, it depends on the specific fanfic. Some might have a plot where Evil Pikachu teams up with other dark - type Pokémon to take over a region. It could involve battles against the traditional Pokémon heroes.
One possible plot twist could be that Bayleef suddenly loses its ability to use grass - type moves. This would put both it and Pikachu in a difficult situation as they rely on Bayleef's moves in battles. They would then have to find a way to regain Bayleef's power, perhaps by going on a quest to find a special herb or meet a certain Pokemon that can help.
It could be about their adventures together. Maybe they explore a new region, encounter other Pokemon, and have to work together to overcome challenges. For example, they might face a powerful, rogue Pokemon that is causing trouble in the forest where Bayleef usually stays. Pikachu's electric attacks and Bayleef's grass - type moves could combine in interesting ways to defeat the foe.
Obviously, Evil Pikachu is a main character. There might also be trainers who are trying to either stop it or control it. Maybe some other Pokémon that are allied with or against the Evil Pikachu could also be considered main characters.
A common theme is friendship. Pikachu and Buneary are often shown as good friends, relying on each other. Another theme could be adventure, as they explore the Pokemon world together.
Often, it's shown as a super - charged version of its normal electric attacks. It might be a more concentrated and intense form of lightning that Pikachu can only use in critical situations in the fanfic world.
A group of Team Rocket - like villains could be the main antagonists. They might want to capture Pikachu while it's in the process of evolving because they believe that an evolving Pikachu would have some special power that they could use for their evil plans. They constantly try to disrupt Pikachu's evolution and the bond between Pikachu and its trainer.
One possible plot could be that Pikachu is exposed to a rare type of thunderstone during a powerful thunderstorm. This thunderstone has been charged with an ancient energy. Pikachu absorbs this energy and begins to evolve. But instead of evolving into Raichu right away, it goes through a series of strange and new intermediate forms, each with unique powers. As it evolves, Pikachu has to learn to control these new powers while also facing challenges from other Pokemon who are either jealous or see it as a threat.
One popular Pokemon Mewtwo x Pikachu fanfic could be 'The Unlikely Bond'. It explores how these two very different Pokemon, the powerful and genetically created Mewtwo and the cute and energetic Pikachu, come to form an unexpected friendship. Their interactions might involve Pikachu's naivete and Mewtwo's brooding nature clashing at first, but then gradually finding common ground as they face a common threat in the fic.
