What are some interesting ideas for D Gray - Man rules fanfiction?

A crossover with Fullmetal Alchemist could also be fascinating. Picture Edward Elric and the D Gray - Man characters collaborating to understand the mysteries of the Gate and the Innocence. Maybe they find out that there are connections between the two in terms of the source of power and the balance of the world. They could also face off against enemies that are a combination of Homunculi and Akuma.

One idea could be a story where the D Gray - Man characters attend a modern - day high school. Allen could be the new kid who seems a bit mysterious, and his strange weapon and abilities start to surface during gym class or self - defense lessons. Another idea is a school play where the characters are cast in roles that parallel their real identities in the D Gray - Man world, and things start to go wrong when real Akuma show up during the performance. A third idea could be a school council story where the characters have to deal with strange events happening around the school that are actually related to the Millennium Earl's plans.

One idea could be to have characters from 'D Gray - Man' interact with characters from another series in a post - apocalyptic setting. For example, they could team up to fight against a new type of Akuma that has emerged due to the crossover's unique circumstances.

One idea could be that the characters from 'Bleach' and 'D.Gray - Man' are brought together to fight a common enemy that is a fusion of Hollows and Akuma. For example, Ichigo and Allen could team up, with Ichigo's powerful Zangetsu and Allen's Innocence combining their powers in unique ways to defeat this new threat.

You could also create a fanfic where the reincarnation process is not perfect. The characters may come back with some of their powers missing or distorted. This could lead to a lot of internal conflict as they struggle to adapt to their new, less - than - perfect selves while also facing the external threats that come with the D Gray - Man universe. They might have to find new ways to fight against the Akuma and the Millennium Earl without relying on their full set of original abilities.

One idea could be that a character is brainwashed by the Millennium Earl to turn against the Black Order. For example, Allen could be made to believe that the Order is the real enemy, leading to some intense battles and internal conflicts within the group.

One plot idea could be exploring the backstories of the Noah family members in more detail. For example, how they became part of the Noah family and what their lives were like before. Another could be a story where a member of the Noah family tries to break away from their dark nature and find redemption. Maybe they form an unlikely alliance with an exorcist.

One idea could be an OC who is a Noah with a unique power that allows them to manipulate time on a small scale. This could lead to interesting interactions with the main characters as they try to figure out the OC's motives and abilities.

One idea could be that the Akatsuki from Naruto are somehow connected to the Noah family in D Gray - Man. Maybe they are both after a powerful and ancient artifact that has the power to change both worlds. Another plot could involve Naruto characters having to deal with Innocence and Akuma in the D Gray - Man universe. For example, Naruto's chakra could be seen as a similar power source to Innocence and he has to learn how to use it to fight the Akuma.

One idea could be the exorcists having to deal with Akuma during a Halloween - themed mission. Maybe the Akuma are disguised as typical Halloween creatures like vampires or werewolves, adding an extra layer of confusion. Another plot could involve Allen Walker stumbling upon a town where a dark magic related to Halloween is causing chaos, and he has to figure out how to stop it while also dealing with his own inner demons.
