In a 'pokemon meets my little pony fanfiction', a great plot could be that there's a dark force threatening both the Pokemon and My Little Pony universes. A group of strong Pokemon like Charizard and a team of brave ponies including Rainbow Dash join forces. They travel through different regions of both worlds, gathering allies and learning new skills from each other to defeat this common enemy. It would be full of action, friendship, and discovery.
One possible plot could be that Naruto somehow gets transported to the My Little Pony world. He might initially be confused by the colorful and peaceful land, but then he could use his ninja skills to help the ponies when they face a threat, like a powerful dark magic user. He could teach the ponies some of his combat moves, and in return, learn about the magic of friendship from them.
One possible plot could be that Spongebob and Patrick get lost in a magical portal and end up in Equestria from My Little Pony. They meet Twilight Sparkle and her friends. Spongebob's positive attitude and Patrick's goofy nature could create some humorous situations as they try to figure out how to get back home while also getting involved in the local pony adventures, like helping to solve a problem with a magic spell gone wrong.
One possible plot could be that some Pokemon accidentally end up in Equestria. The ponies are initially scared but then they realize the Pokemon are friendly. Together, they team up to stop an evil force that threatens both their worlds, like a powerful dark - type Pokemon and an evil unicorn. They use their combined powers of friendship and unique abilities to defeat the enemy.
One possibility is that Deadpool is on a mission in his own universe and there's a portal malfunction which sends him to the My Little Pony realm. There, he might meet Twilight Sparkle who is intrigued by this strange new being. Deadpool could try to teach the ponies some of his combat moves in a really goofy way, while the ponies introduce him to their magic and harmony. This could lead to a story where they team up to face a common threat, like an evil force that wants to disrupt the peace in both their worlds.
One idea could be that the ponies discover Pokemon eggs in Equestria. They start to raise the Pokemon and learn about their powers. For example, Twilight Sparkle could study the different types of Pokemon moves using her magic knowledge.
It could be a more action - packed story. The soldier could be from a world at war, and when he meets the My Little Pony characters, he discovers that their world is also facing some kind of danger. He then teams up with the ponies, using his combat training and the ponies' unique magical abilities to fight off the common enemy. This could be a story about how different strengths can be combined to overcome difficulties.
One possible plot could be that Spongebob somehow gets transported to Equestria. He befriends Pinkie Pie first because of their similar energetic natures. They start having a party together, and Pinkie Pie shows Spongebob around Ponyville. Then, they might encounter a problem like a mysterious spell that's making all the ponies sad. Spongebob, with his positive attitude, tries to help the ponies cheer up and along the way, he meets Twilight Sparkle who teams up with him to find a way to break the spell.
A really interesting plot could be that a powerful villain from Mortal Kombat decides to invade the My Little Pony world. The ponies then have to team up with some of the good - hearted Mortal Kombat characters. Fluttershy, being the kind - hearted pony she is, could try to befriend some of the more aggressive Mortal Kombat fighters and convince them to help protect their world too. The ponies would then have to adapt to the much more violent combat style of Mortal Kombat.
One idea could be a crossover where Pikachu from Pokemon meets Twilight Sparkle from My Little Pony. They could go on an adventure together to save both their worlds from a common threat. Another idea is a story where the trainers from Pokemon enter the world of My Little Pony and have to adapt to the magical and colorful environment while also sharing their Pokemon skills.
A great concept for a Pokemon and My Little Pony fanfiction would be a race. Have some of the fastest Pokemon like Rapidash (which already has a pony - like appearance) compete against the Pegasus ponies in a grand race across different terrains. The story could focus on the training leading up to the race, the rivalries that develop between the Pokemon and ponies, and the unexpected friendships that form. Maybe a little Pony befriends a Pokemon and helps it train in a new way, using pony - style training methods that involve harmony and friendship.
