First, give the OC a unique backstory. Maybe they grew up in an isolated village that had its own special customs, which would influence their values and behavior. Second, give them a distinct personality trait. For example, they could be extremely optimistic in the face of danger, which would contrast with Raven's more reserved nature. Third, give them a specific goal or dream. It could be something like wanting to find a long - lost family heirloom that is said to have great power. This would drive their actions in the story.
Next, focus on character development. Show how the OC and Raven interact and change over time. Their relationship could start with mistrust and gradually turn into respect or even friendship. Also, make sure to stay true to the RWBY universe. Use the existing lore, like the Grimm and the Huntsman academies, to add depth to your story.
One common theme is the exploration of Raven's powers in relation to the OC. Often, the OC might have powers that either complement or contrast with Raven's, leading to interesting interactions.
Well, 'The Unlikely Duo' is another one. In this fanfic, the OC starts as an adversary to Raven but as the story progresses, they find common ground. It has some really exciting fight scenes and a good exploration of the RWBY universe.
One good 'raven x oc jedi fanfiction' could be one where the OC Jedi has to train Raven in the ways of the Force. Their relationship develops as they face challenges together, like battling dark side forces.
Naruto has the ability to create shadow clones. These clones could be used in combination with Raven's empathic powers. The clones could spread out and gather information about the emotions of enemies in different areas, and Raven could then use this information to strategize better. Also, Naruto's Rasengan, a powerful chakra - based attack, could be infused with Raven's Azarathian magic to create a new, even more destructive attack that has elements of both their powers.
Power dynamics is another theme. Given Harley Quinn's complex relationship with power, especially in relation to the Joker, the male oc can bring a new element to this. Maybe he has his own power struggle within the DC underworld, and his relationship with Harley Quinn either complicates or simplifies that struggle. It could also involve themes of loyalty and betrayal, as in the world of DC, alliances can be fickle.
The 'New Teen Titans' run also has great Raven stories. Here, Raven's relationships with her teammates, especially her budding friendship with Beast Boy, are a key part of the narrative. The story delves into her internal battles and how she uses her powers for good, despite the dark forces within her constantly tempting her.
