Pinkie Pie is also a wonderful choice. Her fun - loving and unpredictable nature can add a lot of humor to the crossover. She could throw wild parties in the Equestria Girls world or use her Pinkie Sense to sense trouble coming in a new and different way. And Sunset Shimmer is important too. She has a complex backstory in the Equestria Girls world and her interactions with the MLP characters could be really interesting, especially as she tries to figure out where she fits in with these new arrivals.
Definitely Twilight Sparkle. In both worlds, she's a key character. In the MLP world, she's a powerful magic user, and in the Equestria Girls world, she can bring her intelligence and her problem - solving skills. Also, Rainbow Dash would be great. Her confidence and athleticism in both forms can create really exciting scenes, like when she races against the Equestria Girls' best athletes or uses her pony flying skills to save someone in a high - rise building situation in the Equestria Girls world.
Fluttershy could be a very interesting character to focus on. In the crossover, her gentle nature could contrast with the sometimes more fast - paced and louder Equestria Girls world. Maybe she befriends some shy animals in the Equestria Girls world and helps them gain confidence, while also learning to be more assertive herself. And Applejack, with her honesty and strong work ethic, could get involved in some kind of school or community project in the Equestria Girls world and teach others about the value of hard work.
Maybe there's a villain from the MLP world that follows them into the Equestria Girls world. The girls then have to team up with their Equestria Girls counterparts to defeat this villain. They could combine their different skills, like the pony Rainbow Dash's speed in the air and the Equestria Girls Rainbow Dash's skills on the track team.
MLP Equestria Girls human fanfic often explores unique storylines. It might involve the human versions of the pony characters from My Little Pony in various situations. For example, they could be dealing with high school dramas, friendships, or even some magical adventures in the human world. These fanfics can be a great way for fans to further explore the characters in a different setting.
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.
The main characters are likely to be the Equestria Girls themselves. Twilight Sparkle from the human world would be a central figure as she often takes the lead in many situations. Then there are her friends like Rainbow Dash, Pinkie Pie, etc. Also, the pony versions of these characters might play important roles as they interact with their human counterparts.
The main character is surely the soldier. He might be joined by characters such as Fluttershy. Fluttershy's gentle nature could provide an interesting contrast to the soldier's more hardened personality. And of course, Princess Celestia or Princess Luna could also be part of the main cast, as they are important figures in Equestria and could have significant interactions with the soldier.
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.
There might be a fanfic where Twilight and Flash are in a competition at Canterlot High. It could be a talent show or a sports competition. They start off as rivals but then realize that they can learn a lot from each other. As the competition progresses, they form an unlikely friendship that is really inspiring.
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.
I think Twilight Sparkle would be really interesting. Her vast knowledge of magic could be used in unique ways in the XCOM universe. She could analyze alien technology and find ways to counter it with her spells. Also, her leadership skills from Equestria could be applied to XCOM operations.
