A good MLP female OC fanfiction idea could be centered around a female OC that is a hybrid of different pony types. Maybe she's part unicorn, part pegasus and part earth pony. She feels like an outcast in Equestria at first because she doesn't fit into any one group. But as the story progresses, she uses her unique combination of abilities to save Equestria from a new threat. Or perhaps a female OC who is a fashion - forward pony in Canterlot. She starts her own fashion line that combines traditional Equestrian styles with new, edgy looks and has to deal with the cut - throat fashion industry in the city.
One idea could be a villain OC who has the power to manipulate dreams. They could enter the ponies' dreams and create nightmares, causing chaos and fear. This villain could be motivated by a desire for power over the dream realm.
An interesting concept could be a male human OC who is a talented artist. He gets inspired by the colors and beauty of the MLP world and starts creating art that has a magical effect on the ponies. His art could help solve problems in Equestria, like bringing back the lost colors of a fading meadow.
One idea could be a male alicorn OC who is an outcast in Equestria because of his unique powers. Maybe he has the ability to control time, which is feared by the other ponies. Another idea is a male alicorn OC who comes from a far - off land and has to adapt to the Equestrian way of life. He could bring new magic or traditions with him. A third idea might be a male alicorn OC who is a detective of sorts, using his magic to solve mysteries in Equestria.
You could also write a fanfic about an alicorn OC who forms an unlikely friendship with a non - alicorn character. They go on adventures together and learn from each other, facing various challenges in Equestria along the way.
One interesting plot idea could be that the OC is a new kind of magical being that Aria Blaze has never encountered before. Their meeting causes a stir in Equestria as they try to figure out how the OC's magic works and how it could impact the existing magical balance.
One interesting MLP OC fanfiction could be about an OC who has the power to control time. The story might explore how this power affects the Equestrian world and the relationships with the main MLP characters. It could be full of adventures as the OC tries to correct mistakes in time.
A cool fanfiction idea is a story where a legendary Pokémon ends up in Equestria. For example, Mewtwo could arrive and the ponies initially fear it due to its power. But then they realize Mewtwo is just lost and confused. The ponies, with their kind hearts, try to help Mewtwo find its way back home. Meanwhile, the Pokémon could learn about the magic and friendship in Equestria.
A great MLP Wolf OC fanfiction might involve a wolf OC that has a special power, like the ability to see the future. This wolf OC warns the ponies of an upcoming danger, and together they work to prevent a disaster. It would be full of drama, friendship, and heroic deeds.
One interesting MLP human OC fanfiction could be about a human who discovers they have a special connection to the Equestrian world in the MLP universe. They might start having strange dreams and then find a magical portal that leads them to meet their favorite ponies. It's a really cool concept as it combines the human world with the magical world of MLP.
One idea could be that Thomas the Tank Engine somehow ends up in Equestria. Maybe there's a magical portal that transports him there. He could then interact with the ponies, perhaps helping them with some big construction project like building a new bridge. The contrast between his mechanical world and the magical world of MLP would create a lot of comical and interesting situations.
