An interesting concept for an 'op oc male dxd fanfiction' would be an OC who has an otherworldly form of martial arts. He's so powerful that he challenges the traditional power structures in the DxD world. For example, he could start a school of martial arts that attracts both humans and supernatural beings, which causes a stir among the established groups. His journey could involve him trying to prove that physical strength and discipline can be just as important as magic or demonic powers in this universe.
Well, you could have an OP OC who is a master of ancient magic. He could use this magic to outwit the devils, angels, and fallen angels in the DxD universe. Maybe he has a secret past that ties him to an ancient prophecy, and as he discovers more about it, he has to face powerful enemies. You can also focus on his relationships, like having a romantic interest with a character from the original series that changes the power dynamics between different factions.
