As somebody who’s written OC-centric fanfiction that’s been very well received on AO3, I thought I’d share some advice for those of you who write OC-centric fanfiction. If you want people to like your OC, flesh them out as much as you can, and develop their personality and relationships. If you can, give them an angle that people want in canon, but doesn’t exist in canon. People love my OC Decarabia, because one of her defining traits is that she is a caring auntie to Octavia. People who like Octavia like Decarabia because she cares for and advocates for Octavia, when her parents don’t care about her in canon.
