Doctor Strange would be an interesting character to focus on in a Harry Potter MCU fanfiction. He already has knowledge of magic in the MCU, but it's a different kind of magic compared to that in Harry Potter. He could compare and contrast the two magics, and perhaps even learn new spells from the Harry Potter universe. His presence could also bridge the gap between the two universes in terms of magic.
One could argue that characters like Harry Potter or Sherlock Holmes are among the most famous. They have captured the imaginations of millions worldwide through books, movies, and various adaptations.

First, give your male OC a unique backstory. It could be related to an event in the MCU. For example, if he's from Asgard, his story might involve the fall of Asgard. Second, define his powers or skills. Maybe he has the ability to manipulate energy like Doctor Strange but in a different way. Third, give him some flaws. No one is perfect, and this makes the character more relatable. For instance, he could be overconfident at times, which gets him into trouble.
