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.
A really interesting plot might be that there's a disruption in the balance of nature in both the Pokemon world and Equestria. In the Pokemon world, some Legendary Pokemon are acting strange, and in Equestria, the elements of harmony are misaligned. A group of chosen Pokemon and ponies are brought together by a mysterious force. They have to learn about each other's cultures and powers. For example, a Pikachu could teach a pony about electricity, while a pegasus could show a flying - type Pokemon some new aerial maneuvers. They then figure out how to restore the balance in both worlds through their combined efforts and new - found friendships.
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.
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 Godzilla somehow gets transported to the world of My Little Pony.

So, the ponies, with their magic, decide to help Godzilla fight off this threat and in the process, they learn about each other's strengths and form an unlikely friendship.
One possible plot could be that the ponies from Equestria accidentally stumble into the wizarding world of Harry Potter. They could be initially confused by all the magic there which is different from their own. The ponies might try to help Harry and his friends with their unique pony magic, like Twilight Sparkle using her knowledge of spells in Equestria to solve some of Hogwarts' mysteries. And perhaps the Hogwarts students could learn about friendship in a new way from the ponies.
Well, the plot could involve the ponies somehow getting transported to the Ice Age world. Maybe Twilight Sparkle could use her magic in a wrong way and open a portal. Then they'd meet the Ice Age characters like Manny, Sid and Diego. The ponies' colorful and positive nature could contrast with the harsh Ice Age environment. They could team up to solve a common problem, like finding a way back home for the ponies while also helping the Ice Age animals deal with a new threat.
Definitely Pikachu from Pokemon. Pikachu is super cute and its electric powers would be really cool to see in Equestria. And from My Little Pony, Twilight Sparkle would be great. She's really smart and into magic, so she could be very interested in learning about Pokemon. They could have some really fun interactions together, like Pikachu using its electricity to light up Twilight's library when there's a power outage or something.
A possible plot could involve the Ghost Rider being summoned by an ancient evil in Equestria. This evil wants to use the Ghost Rider's power for its own malevolent purposes. The ponies, led by Twilight Sparkle, team up with the Ghost Rider to defeat this evil. Along the journey, the ponies learn about the Ghost Rider's tragic past and how he became what he is, and they help him find a new sense of purpose beyond just vengeance.
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.
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.
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.
