Reploid

Reploid (レプリロイド) is the name given to the type of android with human-like AI that inhabit the X, Zero and ZX series. The first Reploids were created by Dr. Cain in his attempt to replicate the work of Dr. Light from Mega Man X. X and Zero are not Reploids due to the fact that they are originals (created by Dr. Light and Dr. Wily respectivily) but are referenced as Reploids in the games. Reploids play a larger role in the events of the Mega Man Zero series and Mega Man X4.

Like X, Reploids possess free will and the capability to think, feel and make their own decisions. Unlike Dr. Light, Dr. Cain didn't test them. This is what allowed the Reploids to go Maverick.

Reploids are not to be confused with cyborgs, as they don't have organic parts, and where created before the robot/human hybrids from the Mega Man Legends series.

Mutos Reploid
Mutos Reploid are a kind of Reploids in the Mega Man Zero series created by Neo Arcadia to protect humans. Their designs are based on mythological creatures. The word Mutos possible comes from the Greek word Mythos.
