Mother Brain is one of the main villains of Metroid, a popular Nintendo series. She is the main antagonist and final boss in the original Metroid and Super Metroid. She also appears as a major boss in Metroid: Zero Mission, the GBA remake of the first game.

Mother Brain is essentially a giant brain that has the ability to control Metroids. However, near the end of Super Metroid, the last Metroid turned on her in order to save Samus, the protagonist of the series. Mother Brain killed the Metroid, which made Samus furious. Enraged, Samus killed Mother Brain with the leftover energy given to her by the Metroid, marking the end of her for good. However, some scientists tried to "recreate" her mind in an android named "M.B." (short for "Melissa Bergman" and alternatively "Mother Brain") in Metroid: Other M. This android was later destroyed by the Galactic Federation.

In M.U.G.E.N, Mother Brain has been made by Endoedgar and fhqwhgads7. Endoedgar's version takes on her Super Metroid Form, thus, she has two forms, whereas fhqwhgads7's version looks like her incarnation from the original Metroid, but is in fact completely unique in terms of a bossfight.

Endoedgar's version

Endoedgar's Mother Brain has two forms. Fighting against her AI is essentially a re-enactment of the final boss battle of Super Metroid. The first form (for round one) is a stationary form. She is located in a glass container, which the opponent has to break in order to attack her. Her opponent has to be quick as the arena gets filled up with acid. There is a tiny platform to avoid the acid, but the player might get knocked off it because of the projectiles she shoots out. Her second form (for round two and onwards) is her more deadly form. This forms has deadly attacks such as explosive waves, bombs, and lasers. She gradually gains more attacks as she looses health. When her health is low enough, she will start charging her laser and then fire an unavoidable Hyper Beam attack. If her opponent is low on health before the 1st Hyper Beam, they might not survive it. If the opponent manages to survive the first couple Hyper Beams, she will repeat this process until he/she is low on health. Then, a cutscene will occur. After the cutscene, both players' health will be restored, Mother Brain loses her Hyper Beam move, and her opponent will deal much more damage to her than before.
