One interesting story could be about Jason Blood's OC interacting with the traditional characters in the DC universe. Maybe the OC has a unique power that helps in a battle against a powerful villain. For example, if the OC can manipulate time in a small area, it could change the outcome of a fight with Etrigan.
There are those where the OC is a meta - human with powers that somehow complement Jason Todd's skills. For example, an OC with the power of healing who helps Jason Todd recover from his more serious injuries and in the process, they develop a deep bond. In this type of fanfiction, the relationship between the OC and Jason Todd is often the central focus, exploring how they support and change each other.
First, think about the character of your OC. Decide on their personality, powers, and backstory. For example, if your OC is a shy but powerful mage, you can build their story around how they overcome their shyness to use their powers.
Here's some plot ideas. Jason DiLaurentis could be in the OC on a soul - searching journey. He meets different people who teach him about different aspects of life. He could encounter a reclusive artist who shows him the beauty of self - expression. Then there could be a sub - plot where he has to deal with a jealous acquaintance from his past who follows him to the OC. Another idea is that Jason is in the OC to participate in a sailing competition. He meets a girl who is also into sailing but has a very different approach. Their relationship develops as they train together and face various challenges in the competition.
One interesting Jason Aria fanfiction could be about their adventures in a magical world. Maybe they discover a hidden realm and have to use their unique skills to survive and save the day.
One idea could be an OC who is a powerful vampire hunter sent to the island where the story takes place. They initially clash with the main characters but end up teaming up to face a greater threat. For example, a new type of ancient vampire that is immune to the usual methods of slaying.
In Arkham Knight fanfiction, a Jason Todd OC might have unique abilities or a backstory that ties into the Arkham Knight's world. Maybe the OC has a connection to the criminal underworld in Gotham that Jason can use to his advantage in his fight against crime. It could also be that the OC is a scientist who helps Jason with some of the tech - related challenges he faces.
Love and romance can also be a theme. Some fanfictions explore a romantic relationship between Jason and the OC. This could involve the OC being a new arrival at Camp Half - Blood and catching Jason's eye, or they might have a pre - existing connection that develops into love over time. However, these stories also often balance the romance with the action and adventure elements typical of the Percy Jackson universe.
One possible scenario could be that Jason is in a state of shock. He might be thinking about how this injury could affect his role in the mission. He could be worried about letting his friends down, especially since he's always seen as a strong leader. 'I can't believe this happened. How will I be able to fight like this?' he might be thinking as he looks at his injury.
There might be a fanfiction where Jason Todd and Batman are forced to team up against a new, powerful villain. This villain could be someone who targets Gotham in a way that neither of them can handle alone. Their teamwork in this story would show the evolution of their relationship, from Jason's initial resentment to a grudging respect for Batman's methods as they work together to save the city.
Another plot could be that the OC is an ancient being like Godric, but from a different part of the world. They meet in a chance encounter and discover that they have a shared past that dates back centuries. This revelation could set off a chain of events that affects the entire vampire community in the True Blood universe.
