A crossover with the My Little Pony: Friendship is Magic world (since she's from there originally) but in a different time or place. Maybe Sunset Shimmer ends up in an alternate Equestria where the rules are different. She could meet different versions of the ponies she knew and have to adapt to this new environment while also trying to find a way back home.
A crossover with a superhero universe. Sunset Shimmer could gain superhero - like powers in this new world and team up with other heroes to fight villains. Her strong will and determination from her own story would make her a great addition to the superhero team.
One idea could be a crossover with the Harry Potter universe. Sunset Shimmer could be a new student at Hogwarts, and her magical abilities from her own world could interact in interesting ways with the magic in the wizarding world. For example, her ability to transform might be mistaken for a new and strange form of Transfiguration.
One idea could be that Sunset Shimmer has to balance her pregnancy while still dealing with her magical studies. She might face challenges from her peers who doubt her ability to continue her progress while expecting. Another plot could involve her searching for a special kind of magic to ensure a healthy pregnancy for her and the baby. And perhaps she forms a new friendship with someone who has experience in both magic and motherhood, who guides her through this new phase of her life.
One idea could be that Sunset Shimmer somehow gets transported to the Naruto universe. She could use her magic skills in unique ways there. Maybe she teams up with Naruto to fight against a common enemy like an Akatsuki member who has some strange magic - like powers. They could learn from each other's combat styles and grow stronger together.
A third idea is that the male OC is from a different dimension. He accidentally lands in Equestria and meets Sunset Shimmer. At first, Sunset is suspicious of him but realizes he's lost and in need of help. They embark on a journey to find a way to send him back home. Along the way, they encounter various obstacles and have to rely on each other's strengths. This adventure brings them closer together, and by the time they find a way for him to return, they have developed deep feelings for each other.
Perhaps a story where Sunset Shimmer becomes a Pokemon trainer under Ash's guidance. They travel together, compete in Pokemon battles, and learn from each other's determination and courage.
A really fun plot could be a crossover with a modern - day human world. Shimmer and Shine accidentally end up in a bustling city. They have to hide their magical identities while also trying to find a way back home. Along the way, they befriend a kind - hearted child who helps them understand the strange new world, and they in turn use their magic to help the child with some personal problems.
Begin by brainstorming the plot. Consider the conflict that Sunset Shimmer will face in the crossover world. For example, if it's a crossover with the Avatar: The Last Airbender world, she might face the challenge of learning to control the elements in a world where bending is the norm. You can also start by creating a character profile for Sunset Shimmer in this new context, highlighting how her original traits will change or adapt to the new environment. This will help you write a more consistent and engaging story.
Well, a possible plot could be Sunset Shimmer facing discrimination or misunderstandings from some ponies in Equestria because she's pregnant. This would then lead to a story about her proving herself and showing that she can still be a great friend and contribute to the community. Also, the story could focus on her preparing for the arrival of her baby, like decorating a nursery or learning how to be a mother. And perhaps there could be a sub - plot where she has dreams or visions about the future of her child.
One plot idea could be a male human who discovers Sunset Shimmer's world by accident. Maybe he's a new student at Canterlot High and is immediately drawn to her mysterious aura. He could then help her with some sort of school project that also involves dealing with magic problems in their town.
One idea could be that Sunset Shimmer's little brother is a new student at Canterlot High. He could struggle to fit in at first because of his sister's reputation, but then find his own group of friends through his unique talent, like being an amazing artist. Another plot could involve him getting caught up in a magical mystery where he has to use his wits to solve it and prove himself to his sister.
One plot idea could be Sunset Shimmer facing a mysterious challenge in the human world that only she can solve with the help of Anon. Maybe a magical object is causing chaos and they have to figure out its origin and how to stop it.
