The fanfiction could also focus on the character development of Gray. Meeting his counterpart from another world might make him question his own identity and purpose. This could lead to him growing in new ways, perhaps becoming more confident or learning new magic techniques from the Edolas Gray.
Well, obviously, the two Grays are the main characters. One is Gray from the regular world we know, and the other is Gray from Edolas. Their encounter and the events that unfold around it are likely to be the central focus of the fanfiction.
Some interesting concepts are crossovers. Combining elements from the Gray Matter game with other games or fictional universes. It could bring in new characters and story elements that create a whole new and exciting narrative. Also, the idea of exploring the backstories of minor characters from the game can be really engaging. We get to know more about their motives, their pasts, and how they fit into the overall world of the game.
One interesting concept could be the unique character interpretations. Fanfic often explores characters in ways the original might not have fully delved into, like giving more backstory to the characters in 'the gray garden'.
One interesting concept could be the exploration of new powers for the characters. For example, Allen Walker might develop a different type of Innocence manifestation in the fanfiction. Another could be alternative relationships between the characters. Maybe there are new romantic pairings or stronger friendships that deviate from the original story.
One interesting concept could be the unique relationships that an original character (OC) can form with the existing characters in the D Gray - Man universe. For example, an OC might have a complex friendship or rivalry with the Earl. Another concept could be exploring new powers or abilities that the OC brings to the story, which might change the dynamics of the fight against the Akuma. Also, the fanfiction could delve into different interpretations of the Earl's motives and backstory through the perspective of the OC.
One interesting concept could be exploring how Lucy from Edolas adapts to the Fairy Tail world. Maybe she has different magical abilities or a unique perspective on friendship compared to the original Lucy.
One idea could be that the Exorcists from D Gray - Man end up in the wizarding world of Harry Potter. They might team up with the Order of the Phoenix to fight against a new threat that combines the dark magic of the Death Eaters and the Akuma from D Gray - Man.
A really interesting fanfiction idea would be to set Dorian in modern times. How would he adapt to the modern world with all its technology and different moral values? He might use social media to flaunt his beauty, but also face new challenges. People might be more accepting of his strange situation, or perhaps they would be even more horrified. And how would he deal with modern art? His relationship with his portrait could take on a whole new dimension in the digital age.
One interesting aspect is the exploration of different character perspectives. Fanfiction often delves deeper into the minds of the main characters, like Anastasia and Christian. It can show their relationship from new angles, perhaps how they might interact in different scenarios not covered in the original book. Another aspect is the creativity of the writers. They can introduce new plot elements, such as different career paths for the characters or different family backgrounds that add more depth to the story. Also, it can be a platform for fans to express their own feelings and interpretations of the original story, making it a very personal and diverse form of literature.
One interesting concept could be the exploration of Mana's hidden powers. In the fanfic, perhaps his powers are shown in a new light, like being able to manipulate a different type of dark matter.
