Another plot could involve a crossover with the world of Sherlock Holmes. Detective Pikachu arrives in Victorian London. He meets Dr. Watson and they start to investigate a series of murders. Pikachu uses his unique detective abilities, such as being able to understand Pokémon language which might give clues in this new setting. The mystery could involve a powerful and shadowy organization that is using Pokémon in their evil schemes.
In a crossover with the Star Wars universe, Detective Pikachu could find himself on a strange planet. He teams up with a young Jedi in training. There's a mystery surrounding an ancient Sith artifact that has been stolen. Pikachu's sharp mind and the Jedi's connection to the Force work together to track down the thieves. They face many challenges along the way, including battles with Sith minions and navigating through dangerous terrains.
One idea could be that Detective Pikachu teams up with a character from another universe, like Harry Potter. Pikachu, with his detective skills, could help solve a mystery in Hogwarts. Maybe a series of magical creatures are disappearing, and Pikachu's ability to sense things that others can't would be crucial in finding the culprit.
The third challenge is the fan reaction. Different fans of the original works might have different expectations. Some fans of Detective Pikachu might not like how their favorite character is portrayed in a crossover, and the same goes for fans of the other universe. So, you have to be careful to respect the source materials while also creating something new and exciting in the fanfiction.
First, start with a strong hook. For example, your OC could witness a strange Pokemon phenomenon at the start. Then, introduce the main conflict, like a missing or mutated Pokemon. Build the plot around your OC's journey to solve the mystery, with various obstacles along the way such as uncooperative characters or false leads. End with a satisfying resolution.
The fanfiction could start with Ash and Pikachu finding a magical lemon. When Pikachu touches it, it gets the ability to communicate with all lemon - related Pokemon. They meet a lemon - scented Jigglypuff that tells them about a hidden treasure in a lemon grove. Ash and Pikachu set off to find the treasure. Along the way, they face many challenges, like crossing a river of lemonade and fighting off other Pokemon who also want the treasure. In the end, they find the treasure which is a special lemon that can heal any Pokemon's wounds.
One idea could be an OC who is a detective trainee and teams up with Detective Pikachu to solve a mystery in a new part of the Pokemon world. Maybe they are investigating a series of disappearances of rare Pokemon. Another plot could involve an OC with a special ability to communicate with certain types of Pokemon that Pikachu can't, and together they use their combined skills to stop a villain who wants to use these Pokemon for evil.
A simple plot could be that Tim and Emilia discover a new type of Pokémon that no one has ever seen before while exploring Ryme City. This new Pokémon is in trouble, and they, with the help of Detective Pikachu, try to protect it from some greedy collectors who want to capture it for their own gain.
A more complex plot could involve Detective Pikachu trying to figure out a conspiracy among a group of humans who are trying to use Pokemon for illegal and unethical experiments. This would involve Pikachu teaming up with other Pokemon and human allies, like Tim, to expose the bad guys. They would have to face many obstacles and dangerous Pokemon controlled by the villains along the way.
To write an engaging plot, think about their personalities. Pikachu is lively and curious, Glaceon is elegant and cold. Create a situation where their differences cause problems at first. Maybe Pikachu accidentally ruins Glaceon's ice sculpture. Then they have to work together to fix it. Add some twists and turns, like a mysterious Pokemon that appears and tries to break their newly formed bond. As they face these challenges, their relationship deepens.
The fanfiction could also take a more dramatic turn. Suppose there is a powerful and evil force in Ryme City that wants to take over all the Pokémon. Tim and Emilia, along with Detective Pikachu, are the only ones who can stop it. They have to go through a series of dangerous situations, like sneaking into the enemy's lair and deciphering complex puzzles. Their relationship evolves throughout this journey, and they emerge as heroes of the city.
Some of the villainous Pokémon can also be popular in Detective Pikachu fanfiction. For example, a powerful and devious Pokémon that Detective Pikachu has to outwit. These characters add conflict and excitement to the stories, and their motives and actions can be delved into deeply in fanfiction.
