Redemption is also a theme. Road is often depicted as a more villainous character, and some fanfictions might explore her path towards redemption through her relationship with Allen. It could be about her changing her ways because of her feelings for him.
The idea of redemption is also quite common.

They might face challenges that force them to re - evaluate their beliefs and actions, leading to character growth and development that fans find really interesting.
There are themes like identity. Allen has a unique identity as an exorcist and as someone with a special connection to the Innocence. Fanfictions often explore how this identity affects his decisions and relationships. Additionally, the theme of good versus evil is also common, with Allen being right in the middle of this battle in the D.Gray - Man universe.

Self - discovery is another theme.

Also, the battle against the Akuma and the Noah in unique scenarios is a common theme, presenting new and exciting storylines that deviate from the original plot but still maintain the essence of the D Gray - Man world.
