Category:Expies

Short for "exported character", an expy is a character from one series who is unambiguously and deliberately based on a character in another, older series. A few minor traits — such as age and name — may change, but there's no doubt that they are almost one and the same. Often seen in different works by the same writer(s) or production team.
