Interaction with the existing cast. A good fanfiction will have the OC interacting meaningfully with characters like Issei, Rias, and others. This can include forming alliances, rivalries, or even romantic relationships. It adds depth to the story and shows how the OC fits into the already established world of 'Highschool DxD'. Well - written fight scenes are also important. Since the OC is overpowered, the battles should be exciting and show off their abilities in a cool way, like using their powers in creative combinations against strong opponents.
In this fanfiction, a key element is the conflict that the Son of Sparda OC might face. He's in a new world, Highschool DxD, which has its own set of rules and power dynamics. He may struggle to fit in or be accepted by the different groups. His powers, which are likely a blend of Sparda - like abilities and those related to the devils in Highschool DxD, could make him a target. For instance, some devils might see him as a threat to their power structure. Also, his journey of self - discovery is important. As he learns more about his heritage as the Son of Sparda, he has to figure out how to use his powers and where he stands in this new and complex world.
To create a compelling OC in Highschool DxD fanfiction, first think about their backstory. A tragic or mysterious past can add depth. For example, if your OC is an exiled devil, it gives a reason for their actions. Also, consider their powers. Make them unique but not overpowered to the point of being unbelievable. Maybe they have a special ability related to an element like shadow manipulation that ties into the DxD universe's lore.
Unique character design. If the original character (OC) has a distinct personality and backstory that fits well within the Highschool DxD universe, it can make the fanfiction stand out. For example, an OC gamer who has a special power related to gaming that also has an impact on the DxD world in an unexpected way.
One plot idea could be an OC who is a reincarnated angel in the Highschool DxD world. The OC has to hide their true identity while trying to stop a secret group of devils from starting a war between the three factions. They could team up with Issei and his friends, but there would be constant suspicion from the devils around them.
One idea could be an OC with a unique sacred gear that has powers no one has seen before. For example, a sacred gear that can manipulate time on a small scale, allowing the OC to freeze time briefly during battles in Highschool Dxd's universe. This would add a whole new dynamic to the battles and interactions.
There's a fanfiction where the op oc gamer has the power to level up like in a game. In this story, they use their unique skills to navigate the complex world of Highschool DxD, making allies and facing off against powerful foes. It's really exciting as it combines the game - like mechanics with the supernatural elements of the series.
Well, you could make an OC that is a half - angel, half - devil. This would give the character a very complex backstory and internal conflict, especially in the world of Highschool DxD where the angels and devils have their own politics and power struggles. Also, for the OP part, this OC could have a special ability to combine angelic and demonic powers in a new and powerful way.

One key element is character design. Your Jesus OC should have characteristics that are both in line with the traditional image of Jesus and also fit into the Highschool DxD world. Another important aspect is the power system. Decide how his powers will work and interact with the existing power dynamics in the story. Also, think about the relationships he will form.
