Naruto would probably be really excited. He'd be like 'Whoa! These creatures are so cool!' and would want to befriend them all right away. He might be especially drawn to the more energetic and spunky Pokemon like Charmander.
Well, reacting to a Pokemon fanfic can be really exciting. First, I might focus on how the author has developed the characters. If they manage to stay true to the original Pokemon personalities while also adding their own twists, it's great. For example, if Pikachu in the fanfic shows an unexpected fear of water, which is different from the usual brave Pikachu we know, but is explained well in the context of the story. Then, I'd look at the plot. Is it an adventure that takes us to new and uncharted regions in the Pokemon world? Or is it a more character - centered story about the bond between a trainer and their Pokemon? Another aspect to consider is the writing style. If it's descriptive and makes me feel like I'm right there in the Pokemon world, with vivid descriptions of the landscapes and battles, it's a great fanfic.
At first, Naruto's eyes would widen in surprise. He'd pick up the fanfiction, not really knowing what he's getting into. As he starts to read, he'd be constantly muttering things like 'What the heck?' and 'This is so strange!'. He might try to find someone to explain it to him, but if no one could, he'd likely just shrug it off as something he doesn't need to understand.
Water - type Pokemon like Squirtle could be in a difficult situation. If there are any holes or puddles in the scary house, they might be scared of getting trapped. Squirtle would probably stay close to its trainer, if there is one, and keep its shell towards any potential danger. It might also use its Water Gun as a warning shot if it feels really threatened by something in the house.
His Pokemon might be a bit confused at first. Pikachu, for example, is used to their adventures on the road. But they'll soon adapt. They could make new Pokemon friends at the school too. And they'll be there to support Ash during his school challenges, like in battles or tests.
In these fanfics, Pikachu is without a doubt one of the most popular characters. Its popularity in the main Pokemon series carries over here. It can be written as being curious, mischievous, or even a bit scared in different situations. Next, Psyduck is also quite popular. Its confused nature makes for some hilarious reaction - based scenarios. And who can forget about Jigglypuff? When it gets angry because no one is listening to its song in the fanfic, it creates really engaging and funny storylines.
Meowth would probably be overjoyed. He has been with Jessie and James for a long time and would see their marriage as a great thing. He might be more helpful than ever, running errands for them and even trying to cook for them using his little paws. Their other Pokemon like Ekans and Koffing might be a bit confused at first but would soon get used to the new situation and be protective of their new 'family'.
Ash's Pokemon would likely have mixed reactions. Some like Bulbasaur, being the gentle and observant one, would be quick to accept Sabrina. It might even enjoy the new psychic powers that Sabrina could bring into their group. However, Squirtle might be a bit mischievous at first, trying to test Sabrina's patience. For Sabrina's Pokemon, Alakazam, being highly intelligent, would sense Ash's good intentions towards Sabrina and would support the relationship. Her other Pokemon would follow Alakazam's lead.
Well, for writing a good React Pokemon fanfic, first of all, you need to know the Pokemon universe inside out. This means being familiar with all the different types of Pokemon, their abilities, and their habitats. Then, think about the relationships between the characters. A great fanfic might explore the friendship between two trainers who have very different approaches to Pokemon training. For the plot, you could create a mystery that involves a rare Pokemon disappearing. In terms of writing style, use dialogue effectively. Let the Pokemon and trainers talk in a way that shows their personalities. And finally, add some humor. Maybe a Pikachu that has a habit of getting into comical situations can make the fanfic more enjoyable.
Some Pokemon might show excitement. For example, Pikachu could be all energetic, jumping around as if it's happy to be part of the fanfiction world. It might use its electric attacks in a celebratory way, like creating little sparkles in the air.
