An OP OC can be integrated into the plot by having a personal goal that intersects with the main plot of the Demon King Daimao fanfic. Maybe they are seeking revenge on a particular character who has wronged them in the past. In their pursuit of this goal, they interact with the other characters and events in the story. Their overpowered nature means that their actions have a significant impact. They can also be used to explore new themes in the fanfic. For example, if the fanfic wants to explore the idea of power and corruption, the OP OC's journey from being a powerful entity to potentially being corrupted or remaining noble can be a central part of the plot.
An OP OC can fit into the plot by being a catalyst for change. For example, they could disrupt the existing power balance in the Demon King Daimao world. Their overpowered abilities might make the established characters take notice and react. This could lead to new alliances or conflicts. They might also be a key to solving a big mystery or problem in the fanfic. Say, if there is a curse that no one can break, the OP OC's unique powers could be the solution.
They can fit in as a new threat or a new hope. If the OP OC has a dark side, they could be a new and more dangerous enemy for the protagonists. On the other hand, if they are on the side of good, they can bring new strategies and powers to help the good guys. For instance, if the story is about a war between demons and humans, the OP OC could tip the scales either way depending on their allegiance. They could also introduce new elements to the story, like a new type of magic or a different way of looking at the world in the fanfic.
