There could be an OC who forms an unlikely alliance with some of the more antagonistic characters in the 'Deadly Class' universe. This alliance could be born out of mutual need or a shared goal that is different from what the other students are aiming for, and it would create a lot of tension and interesting character dynamics.
One idea could be exploring the backstories of the minor characters more in - depth. For example, the life of a sidekick before they joined the school. Another could be a 'what - if' scenario where the main character makes a different choice at a crucial moment, like choosing not to go on a certain mission. A third idea is to create a fanfiction that focuses on the relationships between the teachers and how they interact outside of the classroom.
Another memorable OC could be Max. He has a mysterious past that slowly unfolds throughout the fanfiction. His brooding nature and his hidden powers or skills make him stand out among the other characters in the 'deadly class oc fanfiction'.
Well, in fanfiction, OC class cards can vary a great deal. Some might be based on unique magical abilities. For example, a card with the power to control time could be really interesting. It could be used to go back in time to change events in the fanfiction world.
Another possible storyline is that the demigods are transported back in time to an ancient Greek classroom. They have to blend in with the students of that time while also trying to find a way back to their own time. Along the way, they learn more about their own powers and the true nature of their demigod heritage.
Another could be an OC with the Omnitrix getting stuck in a parallel universe where the rules of the Omnitrix are different. For example, instead of being able to transform into known aliens, the OC has to figure out how to use new and strange alien forms that are native to that universe. This could lead to all sorts of adventures as the OC tries to find a way back home.
Another could be a love story within the context of the royals. An original character might fall in love with a royal heir. There could be many obstacles such as differences in social status and the expectations of the royal family. But their love overcomes all these difficulties in the end.
One interesting storyline could be about an original character (OC) who is a half - elf with unique magic abilities trying to find their place in the war - torn world of Warcraft. They might struggle between the two sides of their heritage.
A really engaging storyline might be the OC having to train a young rookie. They take this newbie under their wing, but the rookie has some bad habits that the OC has to break. It's a story of mentorship, growth, and the clash of different generations in the WWE world.
One interesting storyline could be an OC (original character) who is a spy behind enemy lines. They have to use their wits and unique skills to gather intelligence without getting caught.
One interesting storyline could be the nanny getting involved in a local community event in the OC. Maybe she helps organize a charity fundraiser and in the process, she forms new friendships and overcomes some personal insecurities. Another could be her relationship with the family she works for evolving in unexpected ways, like she starts teaching the kids some unique skills that the parents are really impressed by.
