Well - developed characters. Not just Naruto being powerful, but also how his presence affects the existing Highschool DxD characters. If they all have great character growth and interactions because of Naruto, it will stand out. Also, a good writing style that is engaging and easy to read can make it better than other fanfictions.
A really cool concept of power combination. Maybe Naruto can combine his chakra with the Sacred Gears in Highschool DxD. And the fanfiction could explore the consequences and advantages of such combinations. It could also stand out by having a deep and meaningful theme, like friendship or sacrifice, that is intertwined with the story of Naruto being powerful in this new world. This would give it more depth compared to other fanfictions that might just focus on the power aspect.
First, give your OC a distinct personality. Don't make them a typical 'good guy' or 'bad guy'. Maybe they have a sense of humor that's a bit dark or they're overly polite in a world full of brash characters. Second, their power should have a unique origin. It could be something like they got their power from an ancient artifact that was lost in the 'Highschool DxD' world.
Highschool DxD America fanfiction often brings in new characters that are unique to the American context. These new characters can add fresh dynamics to the story, whether they are human allies or new types of devils.
One aspect could be its unique take on the concept of a 'true ninja'. It might explore the essence of being a ninja in a way that other fanfictions don't. For example, it could delve deeper into the moral and ethical dilemmas that ninjas face in the Naruto universe.
Also, pay attention to the world - building. Since Highschool DxD has a rich and complex supernatural world, add more details to it in your fanfiction. Describe new locations, hidden powers, or ancient artifacts that haven't been explored in the original series. By expanding on the world, you make your story more immersive and unique.
Incorporate unexpected plot twists. Instead of the usual battles between the factions, have your OC accidentally start a new conflict that no one saw coming, like a conflict over a new type of power source that has emerged in the Highschool DxD world. This will keep readers engaged.
A powerful Naruto Highschool DxD fanfiction often has a well - thought - out plot that combines the two universes seamlessly. For instance, it should explain how Naruto's abilities work in the Highschool DxD world and vice versa.
The Riser Peerage fanfiction stands out because it can take the often - overlooked aspects of the peerage and make them central. For example, the training and development of the peerage members can be a major focus. We might see how they train together, learn new skills, and bond as a group. Fanfictions can also introduce new challenges for the peerage, like dealing with a curse or a mysterious force that targets them specifically. This creates a sense of exclusivity and uniqueness compared to other parts of the Highschool DxD fanfiction world.
Unique crossovers can make a fanfic stand out. For example, if it combines the magic and devil - related elements of Highschool DxD with the strategic and political aspects of Code Geass in an interesting way. Maybe the main character has to use Geass powers in the Highschool DxD world to deal with devils and fallen angels.
Well, in these fanfictions, the alternate Issei can bring about a whole new set of plotlines. Maybe he has a different attitude towards the devils, angels, and fallen angels. Instead of the usual somewhat lecherous but good - hearted Issei, he could be more serious or more mischievous. This alteration in his personality can lead to different story arcs, such as different battles, different ways of resolving conflicts, and different character growths.
I'm not sure if it's a popular one. It could be popular if it combines the cool elements from Naruto and Highschool DxD well, like Naruto's powerful jutsus in the Highschool DxD universe. But it might not be if the writing is bad or the combination feels forced.
