One of the most exciting aspects of Highschool DxD OC Dragon God fanfiction is the creation of unique characters. Writers can design their own original characters (OCs) with dragon god powers, which adds a whole new layer of intrigue to the story. For example, an OC dragon god could have the power to manipulate time, leading to some really cool plot twists.
Well, a fanfiction like this often delves into the lore of the White Dragon Emperor more deeply. Maybe it gives a backstory to some of his powers that the original series didn't fully explore. The OC in it could be a catalyst for change in the 'Highschool DxD' world. It could be a character from a different faction who comes to understand the White Dragon Emperor in a new way and helps him grow or face new threats.
A good plot idea could be that the OC Dragon God has to hide their true identity in the high school. They are there to find a certain magical item that is hidden in the school. As they search, they get involved with the main characters and have to deal with the normal high school drama as well as the supernatural threats that come their way.
An OC (Original Character) in a Highschool DxD fanfiction having the Rinnegan could be an extremely powerful and unique addition. The Rinnegan, from the Naruto universe, brings a whole set of abilities like the Six Paths powers. In the context of Highschool DxD, this OC could use these powers in various ways. For example, the ability to see chakra could be translated into seeing the magical energy in the DxD world. They could use the gravitational powers of the Rinnegan to manipulate the environment during battles against devils, angels, or fallen angels. It would make for a very interesting and overpowered character in the Highschool DxD fanfiction setting.
Well, some storylines involve the OC dragon having a special bond with one of the main characters from Highschool DxD. This bond could be based on a shared goal, like finding a powerful artifact that is important to both the dragon and the character. It could also be a more emotional bond, like the OC dragon helping a character through a difficult time. There are also storylines where the OC dragon is an outcast from their own dragon clan and has to prove themselves in the world of Highschool DxD.
The 'Redemption' trope is often seen in 'Highschool DxD White Dragon Emperor OC Fanfiction'. Maybe the OC has a dark past that they are trying to atone for, and their relationship with the White Dragon Emperor helps in that journey. The 'Alliance' trope is also popular, with the OC forming an alliance with the White Dragon Emperor against a common enemy. This can lead to epic battles and strategic planning within the fanfiction. And don't forget the 'Discovery' trope, where the OC discovers something new about the White Dragon Emperor or vice versa, which can change the course of the story.
Well, for creating an OC (Original Character) as a Dragon God in a Highschool DxD fanfiction, first think about their powers. A Dragon God could have the power of elemental manipulation, like controlling fire or ice. Their appearance could be a mix of human and dragon features. Maybe they have dragon wings that can be hidden at will. Another important aspect is their backstory. They could be an ancient being that has just awakened in the modern Highschool DxD world.
One idea could be a dragon OC that has the ability to transform into different elemental forms. For example, it can be a fire - breathing dragon in combat situations, but a water - based dragon for healing or stealth purposes. This would add an interesting dynamic to the story as it could befriend different characters based on its form.
Start with their backstory. Decide where they came from, how they became a dragon slayer. Were they trained by a master? Or did they have a personal vendetta against dragons? This will shape their personality.
One idea could be an OC who is a dragon slayer but has a unique power that sets them apart. For example, they can absorb the powers of the dragons they slay instead of just killing them. This could lead to all kinds of new storylines as they become more powerful and are hunted by both good and bad forces in the Highschool DxD universe.
