What are fictives? And are the majority of plurals fictives, or is just a minority that identifies that way?
Fictives are headmates with identifiable source material. Captain America (Marvel), the Doctor (Doctor Who), and Chell (Portal), are all fictives in this system. I don’t know what the ratio of fictives to non-fictives is, and honestly, it’s a matter of self-identification. I know some fictives who want nothing to do with their canon, or who don’t feel particularly attached to it.
