Another plot could involve an OC Wolfblood who gets separated from their pack during a big event, like a natural disaster or a human - caused disturbance. They then have to survive on their own and find their way back to the pack while facing various challenges and making new allies or enemies along the way. For example, they might encounter other supernatural beings who are initially hostile but later become friends.
One idea could be an OC who is a new Wolfblood in a pack and has to prove themselves. Maybe they have a unique power that the others don't have and they have to learn how to control it while fitting into the pack's hierarchy.
One idea could be a wolfblood having to hide their identity in a new school where there are rumors of a werewolf hunter in town. They have to constantly be on guard while also trying to make friends and fit in.
Well, you could write a fanfiction where the magic in the Wolfblood world somehow interacts with the Greek mythology in Percy Jackson. For example, the moon phases that are important for wolfbloods could have a different effect on the demigods. Maybe during a full moon, the demigods' powers are enhanced in a new and unexpected way. Or perhaps a wolfblood gets sent to Camp Half - Blood by mistake and has to learn to live among the demigods while hiding their true nature.
One idea could be a fanfic where a new Wolfblood arrives in an established pack and has to prove themselves. They might face challenges like learning the pack's unique traditions and dealing with rivalries within the group.
Another plot could revolve around an OC who is a Spartan trainee that doesn't quite fit the mold. They have a different way of thinking and approaching combat. In Halo 4, they end up being the key to solving a mystery related to the Prometheans. Maybe they find a way to communicate with the Prometheans and convince some of them to stop fighting the humans.
One idea could be an Otsutsuki OC who comes to Earth not for conquest but to study the unique life forms here. They could befriend some of the local ninjas and learn about the concept of friendship, which is alien to the Otsutsuki. This would lead to a series of adventures where they have to protect their new friends from other more hostile Otsutsuki members.
One idea could be an OC who is a long - lost relative of Moana. This OC could have been separated from the family during a great storm years ago. They could have unique skills, like being able to communicate with a different type of sea creature that Moana has never encountered. This would bring new adventures as Moana and the OC try to figure out how this new discovery could help their island.
One idea could be exploring the origin of the OC in the covenant world. Maybe they have a special power that sets them apart from the regular covenant members.
One idea could be an OC who is a long - lost relative of one of the main characters. They suddenly show up and cause a stir in the power dynamics. For example, if they are related to the main heir, they might have a claim to the inheritance as well, leading to all kinds of family drama and power struggles.
One idea could be an OC who is a brilliant but unorthodox medical student. They constantly clash with House in their diagnostic methods yet prove to be surprisingly accurate at times. For example, they might use a new technology or approach that House is initially skeptical about but later comes to respect.
One idea could be an OC with the power to manipulate time joining the Incredibles. They could use their power to prevent disasters or even go back in time to change events that led to Syndrome's rise. Another idea is an OC who is a super - fast healer. They could play a crucial role in patching up the Incredibles after tough battles.
