One good idea is a time - travel fanfic. For example, the ponies accidentally travel back in time to the founding of Equestria. They get to see how the different pony tribes came together and learn about the origin of their magic and society. But their presence in the past starts to cause some disruptions, and they have to figure out a way to fix things without changing history too much. This could involve interacting with the ancient ponies and learning valuable lessons about their own present - day Equestria.
An interesting fanfic idea could be about a pony who has always been in the background, a sort of extra in Ponyville, suddenly getting a very important role. Maybe this pony discovers a hidden talent that is crucial to saving Equestria from a new villain. The story could focus on this pony's journey from being unnoticed to becoming a hero, and how the other ponies react to this sudden change. It would also explore themes of self - discovery and the potential that every pony has, no matter how ordinary they seem at first.
One idea could be to have the ponies from MLP end up in the Ninjago world. Maybe Twilight Sparkle could use her magic to help the Ninjas in a big battle against an ancient evil. The contrast between the colorful and magical ponies and the more martial arts - based Ninjago characters would create an interesting dynamic.
One idea could be a story where a new pony arrives in Ponyville with a unique magical ability that no one has seen before. This pony struggles to fit in at first because the other ponies are both curious and a bit scared of this new power. As the story progresses, the new pony uses their ability to save the town from a natural disaster, thus winning the acceptance and friendship of the other ponies.
One idea is to have a story centered around a pony who has lost their sense of taste and has to rely on the reactions of their friends to know if their cupcakes are good. They go on a journey to find a magical ingredient that can restore their taste. Or perhaps a group of ponies travel to a far - off land in search of rare cupcake - making ingredients. Along the way, they face various challenges and meet new pony tribes with different cupcake traditions. They then bring back these new ingredients and ideas to Equestria and create a whole new style of cupcakes.
A fanfic could be written about Sapphire Shores' influence on the younger ponies in Equestria. It could show how she inspires them to pursue their dreams in the field of music or performing arts, and how she uses her fame for good in the pony community.
One idea could be that there's a lemon - colored reindeer in the MLP world. It has special powers related to lemons, like it can create lemon - scented shields or use lemon juice to heal wounds. The MLP ponies are initially skeptical but then come to rely on the reindeer's powers during a big battle against an evil force.
You could make Rainbow Dash a vampire with the ability to fly at super - sonic speeds even for a vampire. She might struggle with her new blood - lust while still trying to be loyal to her friends. Maybe she has to compete in vampire - only races in the night sky.
In an MLP Cupcake Fanfic, you might explore the idea of a cupcake - making class taught by Pinkie Pie. The students could be all different types of ponies with different skills and personalities. Some might be really good at following recipes, while others are more creative and come up with unique cupcake designs. There could be a sub - plot about a pony who is initially shy but gains confidence through the class. Also, the fanfic could include a big cupcake festival at the end, where all the ponies show off their new cupcake - making skills.
One idea could be a story where the ponies discover a hidden world of dinosaurs. They might have to learn to communicate with the dinosaurs and figure out how to co - exist. Maybe there's a magic element involved that brought the dinosaurs to Equestria in the first place.
Another interesting concept is that the ponies from MLP gain superpowers similar to Spider - Man. For example, Rainbow Dash could have the ability to swing from clouds like Spider - Man swings from buildings. They could then fight a common enemy that threatens both their worlds, and Spider - Man has to teach them how to use their new powers effectively.
One idea could be a crossover where the characters from DuckTales accidentally end up in the world of MLP. Maybe Scrooge McDuck is on one of his treasure hunts and discovers a magical portal that leads him and his nephews to Equestria. There, they meet Twilight Sparkle and her friends. They could team up to solve a problem that is affecting both their worlds, like a villain who is stealing magic from both Duckburg and Equestria.
