Mother Brain is a recurring antagonist in the ''Metroid'' series, first appearing as the final boss of the original ''Metroid'' in 1986. She is an artificial intelligence housed within a giant brain-like cyborg body, who controls the Space Pirate forces on the planet Zebes and organizes their plot to control the Metroids. Fitting her appearance, she is extremely intelligent and serves as a dangerous leader despite her physical limitations.

 

In ''Metroid'' (1986), Samus faces Mother Brain within the depths of Tourian, after fighting through hordes of Metroids propagated by Mother Brain and the Pirates. Samus must fire missiles to create an opening in Mother Brain's Control Capsule, then continue to fire missiles through that opening to damage her, all while avoiding an onslaught of security systems such as Rinkas and acid. After Mother Brain's defeat, a time bomb is activated and Samus must escape Tourian before it explodes, ending the game.

 

In ''Super Metroid'', the Space Pirates of Zebes return alongside Mother Brain to harness the Metroids once again. The first half of Mother Brain's battle is almost identical to the one in ''Metroid''. After Mother Brain is seemingly defeated, she attaches to a giant bipedal body with incredible attack power. After sustaining enough damage, she uses her Laser Brain Attack to completely overwhelm Samus and bring her to her knees. Samus is only saved by the Baby Metroid, which sacrifices itself to weaken Mother Brain and heal Samus, granting her the Hyper Beam. Samus uses the Hyper Beam to destroy Mother Brain's new body, activating another time bomb that this time consumes all of Zebes. This is the final demise of Mother Brain in the series timeline.

In the ''Metroid'' remake, ''Metroid: Zero Mission'', Mother Brain's battle is nearly identical to the original form. However, after the Control Capsule is broken, she opens her eye and fires blasts in retaliation. In ''Metroid: Other M'', Mother Brain's fight with Samus in ''Super Metroid'' is depicted in a flashback, and the Galactic Federation later creates an AI based on her called MB. Although Mother Brain herself is absent in ''Metroid Dread'', brain mechanisms similar to Mother Brain called Central Units appear in the game along with Rinkas. She is also depicted in some art adorning the walls of Chozo structures in Ferenia.

|desc-ntsc=Hailing from the Metroid series, this evil boss resides on the planet Zebes. When she appears in Smash Bros., she attacks with energy projectiles and a beam from her eye. It's actually possible to defeat her, and for once doing so won't start a self-destruct sequence.

|desc-pal=A mainstay of the Metroid series and the final boss Samus faces on Planet Zebes. In this game, she grows to a gargantuan size and fires all sorts of energy blasts at you. Good news: you can beat her! Better news: doing so won't trigger a self-destruct sequence forcing you to make your escape!

|desc-ntsc=When Samus first encountered her on the Bottle Ship, she introduced herself as Madeline. Only later did Samus discover that she was actually an android named Melissa, also called MB. As Melissa's hatred for humans grew and became more apparent, the human scientists attempted (and failed) to reprogram her.

|desc-pal=When Samus first encountered her on the Bottle Ship, she introduced herself as Madeline. Only later did Samus discover that she was actually an android called Melissa, host to the artificial intelligence known as MB, and that she bore a grudge against humans for trying to reprogram her after she developed emotions.

Mother Brain returns as an Assist Trophy in ''Super Smash Bros. Ultimate'', seemingly without any change in function. However, KOing her will now earn a point. [[Training Mode]] describes her Assist Trophy: ''Shoots a powerful beam from her eye. Rinkas help her out.'' She cannot appear in Luigi's Mansion, Pac-Land, Rainbow Cruise, Spirit Train, The Great Cave Offensive, Tomodachi Life, Tortimer Island, and Umbra Clock Tower.

Mother Brain also appears as two different [[primary spirit]]s. Mother Brain (2nd Form) can be obtained by [[Enhanceable spirit|enhancing]] the Mother Brain spirit at level 99.

 

In [[Adventure Mode: World of Light]], Mother Brain is presumably one of the countless spirits captured by [[Galeem]] during his takeover of the universe. After Galeem's defeat, [[Dharkon]] takes control of Galeem's spirits, including Mother Brain. After Dharkon's defeat, he flees to the final world, with Galeem following soon after. In the final world, Galeem and Dharkon wage war against each other using their captured spirits, with Dharkon taking control of Mother Brain.

 

Mother Brain's Spirit Board uses a {{SSBU|Dark Samus}} puppet fighter and is fought on the [[Brinstar Depths]] stage's [[Ω form]]. During the battle, Mother Brain appears as a hostile Assist Trophy while Dark Samus' energy attacks have increased power, referencing Mother Brain's Laser Brain attack, which she uses in her second form.
