Android

An Android is a robot or synthetic organism with the purpose of emulating human appearance and action. Thus far, only one android has been seen in the Metroid Series, the AI construct made to reproduce Mother Brain's control, Melissa Bergman. Since she was of Galactic Federation design, it can be assumed that there are more androids in the series. At the time of ''Metroid: Other M, androids were able to almost perfectly represent human appearance, making it impossible to distinguish a human and an android externally.
