Reploids

Reploids (レップロイド, Repuroido) are androids with complete free will and thought processes comparable to that of humans.

Characteristics
Reploids can be thought of as the next evolutionary step of the robots from the classic series. For all intents and purposes, Reploids are the same as humans on a mental level; they think and feel, giving them the ability to make their own decisions and develop unique personalities. Although Reploids undergo major physical changes throughout the series, they generally retain this one trait with the exception of mentally degraded Reploids such as the Pantheons.

Advanced types of Reploids
Other than the default characteristics of the widely-produced Reploids out there, many and more generation as well as development of Reploids have been made throughout the series.
