The plot should be engaging. It should take advantage of the crossover aspect. For instance, if it's a crossover with a magic - based universe, the plot could revolve around a power struggle that involves both the magic from that universe and the unique powers in High School DxD. This creates a complex and exciting story that keeps readers on their toes.
One key feature is the integration of different universes. For example, how well the rules and elements of the other crossover universe fit with High School DxD. If it's a smooth blend, it's usually a good sign.
Originality. With so many crossovers out there, it's great to find one that has some unique twists. Maybe it's a crossover where the normal rules of both series are changed in a creative way. For instance, in a 'highschool dxd' and 'Sword Art Online' crossover, the way they combine the virtual reality and devil powers in a new way can make the fanfic really stand out.
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.
One common theme is power. In both Prototype and Highschool DxD, power plays a crucial role. Fanfictions often explore how characters from one universe would adapt to the power levels in the other. For example, a character from Prototype might find the power of the devils in Highschool DxD either overwhelming or underwhelming.
The unique feature is the combination of two very different universes. Pokemon's world is full of cute creatures with various powers, while High School DxD has a more mature and complex power system. When they cross over, it's like mixing two different kinds of magic.
One popular 'highschool dxd prototype crossover fanfiction' is 'The Hybrid Hero'. It combines the unique elements of the High School DxD universe with other interesting concepts. The story often has exciting battles and character developments.
One popular trope is the 'Fish out of Water' scenario. For example, a character from Prototype suddenly finding themselves in the Highschool DxD world full of devils, angels, and other supernatural beings. It creates a lot of comical and interesting situations as they try to adapt.
One idea could be to create an alternate universe where the main character has a different set of powers. For example, instead of the traditional Sacred Gear, they could have a power related to time manipulation. This would change the dynamics of battles and interactions with other characters.
A good plot. Since it's a crossover, the plot should blend the two different fictional elements seamlessly. For example, if it's a crossover with a fantasy world, the story should make sense in terms of how King Harlequin fits into that world.
Well, first, the fanfic should respect the lore of both SCP and JJBA. If it starts messing up the basic rules of either franchise, it can be a turn - off. The pacing is also crucial. A good crossover will have a well - paced story that doesn't rush through the interactions and developments. And finally, the world - building. How the two universes are merged should be creative and believable, like how the locations from JJBA fit into the SCP facilities or vice versa.
Good character development is key. Since it's a crossover, seeing how the FNAF nightmare characters interact and change in the new setting is important. For example, if they cross over with another horror franchise, how do they respond to new threats or allies? Another feature is a unique plot. It shouldn't just be a rehash of the original FNAF nightmare story but something that takes advantage of the crossover concept, like a new mystery or conflict.
