Well, 'Rarijack' fanfics in the MLP Equestria Girls universe can be really interesting. They often explore the relationship between Rarity and Applejack in unique ways. Some fanfics might focus on their friendship, showing how they support each other through different challenges in Canterlot High. For example, there could be a story where they have to work together on a school project and in the process, they learn more about each other's strengths and weaknesses.
There's also 'Rarijack and the Lost Friendship'. This one is a bit more emotional. It starts with a rift in their friendship due to outside influences. But as the story progresses, they realize the importance of their bond and work hard to fix it. It's a great exploration of their relationship.
A popular one is 'Sunset Shimmer: A New Beginning'. This fanfic focuses on Sunset starting a new chapter in her life at Canterlot High. It's a heartwarming story about friendship and self - discovery, with Sunset learning to trust others more and open up about her own feelings.
One great trope is the 'fish out of water' scenario. The main character from Equestria suddenly finding themselves in a human world and building a harem can lead to some really interesting and comical situations. For example, they might misunderstand human customs which then endears them to the other characters in the harem.
A really popular one is the fanfiction that focuses on Twilight's relationship with her friends in the Equestria Girls setting. It shows how they support each other through school problems, boy - girl drama, and still manage to keep their magical bond intact.
There's a fanfic called 'Kyle and the Equestria Girls Mystery'. In this one, Kyle teams up with the Equestria Girls to solve a mystery that is threatening to disrupt the balance between the human world and Equestria. It's full of suspense and great character interactions.
There could be some magical mishaps. Maybe the photo booth is enchanted and instead of normal photos, it creates pictures where the girls are swapped with their pony forms in a really strange and comical way. The photo booth could also make their outfits change colors randomly with each flash, leading to some very colorful and unexpected pictures.
Don't rush the relationships. As I mentioned before, a slow - burn can be really effective. Let the characters get to know each other gradually. Also, add some conflict. It could be jealousy among the harem members, or an outside force trying to break them up. This adds drama and keeps the story interesting.
In the photo booth, Rarity was very concerned about how she would look in the photos. She was constantly adjusting her hair and outfit. Applejack just rolled her eyes and told her to relax. Meanwhile, Fluttershy was quietly waiting for her turn. When it was finally her turn, she managed to smile sweetly. The girls took turns in different combinations, and the photo booth was filled with their laughter and chatter as they created a collection of photos that showed their unique friendship.
One popular fanfiction could be 'Twilight and Timber's Adventure'. It might have them going on an exciting journey through different dimensions in Equestria Girls' world. They could face challenges together and their relationship could develop in interesting ways.
