Expy

Character Copy, a Cut and Paste. In fanfic or roleplaying communities, particularly the text based or tabletop varieties, an expy is a character heavily based off of an already established canon character from popular culture or media. The expy will often retain most, if not all of the established character's aesthetics and abilities with only a simple palette swap or small token change to outfit, hairstyle or eye color to differentiate between the two physically. Character histories can also be blatant rip offs of the source material. The term is most often used derisively as a critique against lazy or uncreative players during character generation. Often linked with compulsive Mary-Sueism.
