A great storyline in Apple Jack fanfiction could be her dealing with a rival apple - growing farm. There could be a competition between them, and Apple Jack has to use her wits and her family's traditional methods to come out on top. Also, a story about her helping a lost pony find their way back home while also taking care of her own farm duties would be quite engaging. These storylines show different aspects of Apple Jack's character.
One interesting storyline could be Apple Jack's journey to find a rare apple variety that is said to have magical properties. This could involve her traveling to different parts of Equestria, facing various obstacles along the way, and making new friends. Another storyline might be her trying to teach the younger ponies in Ponyville about the importance of hard work and honesty, just like she learned from her family.
In some fanfictions, Apple Jack might be involved in a mystery. For example, strange things start happening in the apple orchard, like apples disappearing without a trace. She then has to investigate, suspecting that it might be some kind of magic or a sneaky critter. This kind of storyline keeps the readers on their toes and allows for a lot of creative exploration of Apple Jack's detective - like skills.
One possible storyline could be Twilight's journey of self - discovery while pregnant. She might struggle with balancing her new physical state and her responsibilities as a princess. Another could be about the reactions of her friends, like how they support her during this special time.
A storyline could be that Rapunzel's long hair has some special connection to the pregnancy. Maybe her hair glows brighter as the baby grows inside her, and Jack has to figure out how to protect this new magical aspect. Another idea is that Jack discovers he has some hidden powers that surface to protect Rapunzel during her pregnancy.
One interesting storyline could be a human getting accidentally transported to Equestria and having to learn the ways of the ponies while forming deep friendships. They might help the ponies solve a big problem like a drought or a magical mystery. Another could be a pony coming to the human world and experiencing human culture for the first time, like going to school or trying different foods. There are also fanfictions where a human and a pony have a telepathic connection that allows them to understand each other on a deeper level and work together to save both their worlds.
One interesting storyline could be a female Jack Frost being a new recruit in the X - Men. She could use her ice powers in unique ways during battles, like creating ice sculptures that can come to life and fight alongside the team. Maybe she has a backstory of being from a frozen dimension and is trying to adapt to the world of mutants.
One interesting storyline could be Jack and Akiko teaming up to face a new and powerful enemy that neither could defeat alone. They combine their unique skills, Jack's samurai training and Akiko's own special abilities, to outwit the foe.
Well, I've come across some mlp apple fritter fanfic where Apple Fritter is depicted as having a special talent discovery journey. It shows her growth and how she overcomes challenges related to her newfound talent. These fanfics often have great character development.
One interesting storyline could be the characters from Durarara finding themselves in the colorful world of Equestria in MLP. For example, Celty might be mistaken for some kind of strange new creature. The contrast between the urban, often gritty setting of Durarara and the bright, magical world of MLP can lead to some really unique interactions. Characters like Mikado could be fascinated by the magic and harmony in Equestria and try to learn from it, while the ponies might be both intrigued and a bit scared of the more 'edgy' characters from Durarara.
One interesting storyline could be Pokemon trainers arriving in Equestria and learning about the magic of friendship there. They might team up with the ponies to solve problems, like dealing with a group of misbehaving Pokemon that are causing chaos in Ponyville.
One interesting storyline could be Future Trunks getting transported to the My Little Pony world. He might initially be confused by the colorful and peaceful place. Maybe he tries to find a way back home while also getting involved in the local ponies' problems, like helping them fend off some new threat that his fighting skills could be useful against.
One interesting storyline could be their race against time to find a hidden island. Jack Sparrow has a map or a clue, and Calypso, with her knowledge of the seas, helps him navigate. Along the way, they face various challenges like storms, other pirates trying to steal their information, and mythical sea creatures. This is all about adventure and cooperation.
