We lack a serious amount of Male OC fics (mlm). And I can rarely find any that are well written, most OCs are just given the traits of an existing character, like wdym I'm not reading a drarry fic? That's literally Harry.
Ps. I love characters who have weird quirks, like YES GIVE THEM TO ME!! This makes me want to finally write the Regulus/MOC fic that has been on my mind for months now; I've planned the ending, which is, in my opinion, the most important part of starting a story. His name is Artemis Lupin, and other than some physical similarities, he and Remus cannot be more different.
