What role could Alduin play in a High School DxD fanfiction?

One way could be by making Alduin a powerful transfer student. He could bring his dragon - like powers and a sense of mystery to the school. His presence might disrupt the existing power balance among the devils, angels, and fallen angels in the High School DxD world.

He could play the role of a protector. Gaara has always been one to protect those he cares about, and in High School DxD, he could use his sand powers to safeguard the students from various threats, whether it's from rogue devils or other dangerous entities.

Firebrand could be a student in the High School DxD setting who has a strange connection to the Naruto world. Maybe they have dreams or visions of the Naruto world and start to develop ninja - like abilities in the High School DxD world. This could lead to them being an outcast at first, but as they grow in power, they become a key figure in protecting the school from threats that are both from the High School DxD universe and potentially threats that have some connection to the Naruto world.

They can be the voice of reason. In a world of High School DxD where there are a lot of crazy supernatural events, an atheist character can question the norm. For example, if there is a plan to use some ancient religious artifact, they might ask why it's necessary.

The role could be that of a mediator. Since angels are often seen as more morally upright in the 'High School DxD' lore, this OC with holy fire could try to keep the peace between the different factions like devils and fallen angels. For example, when a fight breaks out between the devils from Rias' group and some fallen angels, the angel OC could step in and use their holy fire as a warning or to actually stop the fight.

He could be a mentor figure. Given his vast experience and moral compass, he could guide the main characters in High School DxD. He might teach them about true heroism and the importance of using their powers responsibly.

Ares could be the antagonist. He might be there to create conflict among the students, like starting rivalries or fights. Maybe he's looking for a particular student with special abilities for his own devious plans.

Well, he could be a powerful antagonist. His skills and power from the Dragon Ball universe would make him a formidable foe in the High School DxD world. He might be interested in the power of the devils and angels there and try to take it for himself.

Goku Black might become a sort of anti - hero. He has his own sense of justice (albeit a twisted one in his original story). In the High School DxD world, he could oppose some of the more corrupt elements of the different factions while also causing trouble for the main characters as they try to figure out his motives. For instance, he could see the way some devils treat humans in the DxD world and decide to take matters into his own hands, but not in a way that the main characters would necessarily approve of at first.

The character could be a catalyst for change. The EMS gives them access to powerful abilities. In the High School DxD world, which is often about power struggles and hierarchies, their presence could disrupt the status quo. They might inspire other characters to strive for greater power or to question the existing power structures. For example, if they use their EMS to defeat a powerful devil who has been oppressing others, it could start a movement among the weaker characters to stand up for themselves.
