Mother Brain

Mother Brain (マザーブレイン Mazā Burein?), sometimes shortened to simply Mother, is a recurring antagonist in the Metroid series. She is an ambitious and ill-tempered artificial intelligence created by the Chozo, who turned against them to lead the Space Pirates instead. As the head of the Pirates on Zebes, Mother Brain improved their military strength and thus, along with her plan to weaponize the Metroids, posed a massive threat to galactic society.
Mother Brain served as the main antagonist in Metroid, Super Metroid, and Metroid: Zero Mission. She is seen in a flashback during Metroid: Other M, and an android based on her was the antagonist of that game as well. On the Japanese website for Zero Mission, she is given the title Mad Overseer (狂気の支配者?).

Mother Brain functioned the same way as it would in Super Metroid: always watching over Samus' every move, manipulating the space pirates, killing off the Chozo, having the baby Metroid abducted and soon killed by it while saving Samus, and meet her demise which caused Zebes to self-destruct.
