This is a list of recurring characters appearing in the Mega Man X series of video games developed and published by Capcom. Unless otherwise stated, each of these characters is a reploid; an artificially intelligent android. Names are organized in order of appearance, and characters who only appear in a single game are covered in the article for the corresponding game.
The Maverick Hunters (Irregular Hunters イレギュラーハンター in Japan) are a group of Reploids who protect humans and other Reploids from Mavericks and the heroes of the Mega Man X series, and the protagonists of each game are prominent Maverick Hunters. When they are introduced in Mega Man X, they have already existed for quite a while, having been previously founded by Dr. Cain (who has since retired). From Mega Man X on, they battle Sigma and the other Mavericks.

As is explained in the original Mega Man X, he is the template on which all non-Light model Reploids (except Zero) are based, and he battles against Mavericks to protect humans and assuage his guilt for his part in their creation. He was created by Dr. Light sometime in 20XX. Light named him X after the variable "x" which, in algebraic terms, represents limitless possibility, as do X's advanced systems.
