Well, it's possible that a single character who has a special ability or a big secret could be the protagonist. This character might be trying to hide their true nature from the others at Canterlot High at first. But as the story progresses, they have to reveal it in order to save the school or their friends. For example, they could have a power to control time or read minds, and this ability becomes crucial in solving the problems that the school faces.
The most memorable scenes in a 'A Trip to Canterlot High Fanfic' could include the cafeteria scenes. Here, all the different cliques gather, and there are lots of interactions, from friendly chats to little rivalries. Then there's the scene where a new student arrives and shakes up the social order. Everyone has to adjust to this new person, and it creates a lot of interesting storylines. And the scene where the school goes on a field trip to a really cool place, like a magical forest or an old castle, would be super memorable as it would be full of adventure and discovery.
It usually has exciting adventures and unexpected plot twists. The characters' interactions are often very engaging.
I think Luna Lovegood could also be included. Her unique perspective and knowledge of the magical world would add an interesting element to the road trip. She might lead them to discover some really strange and wonderful things.
Clawdeen Wolf from Monster High and Cerise Hood from Ever After High. Clawdeen is very fashion - forward and Cerise has her own unique style. They could share fashion tips while also dealing with the challenges that come from their different backgrounds in this crossover scenario.
Sunset Shimmer is extremely popular. She has a complex backstory, having once been a villain but then redeemed herself. Her journey of self - discovery and growth makes for great fanfiction material. Then there's Twilight Sparkle, who brings her book - smart and sometimes naive personality to Canterlot High. Also, Rainbow Dash with her competitive and loyal nature is often a favorite. She can be involved in sports - related plots or stories about loyalty among friends.
Another possibility is Bulbasaur. It has always been a loyal and steady companion to Ash. During the trip, it could see how far they've come together and confess its gratitude for all the experiences and growth they've shared.
Twilight Sparkle would likely be affected as she is often at the center of things in the MLP universe. Her actions and decisions would be crucial in any alternate ending, whether she's saving the day or facing new challenges.
Typically, the young ninja trainees like Naruto, Sasuke, and Sakura could be the protagonists on Chunin Exam Day in a fanfic. They are the main characters in the original series and are likely to play important roles in any fan - created story about the exam.
Bella Swan is a very likely character. Since she has such a strong connection to Forks, which is her home in the Twilight world. Her journey home could be filled with thoughts of Edward and the vampires she has come to know.
Naruto and Sakura are likely to be a couple. Naruto has always had a thing for Sakura, and in high school, Sakura might start to see Naruto in a different light as he matures. Another possible couple is Sasuke and a new character, a smart and independent girl who can match Sasuke's intelligence and aloofness. They would have a very intense relationship.
