MB, nicknamed Melissa Bergman, is the main antagonist of Metroid: Other M.

Samus Aran first saw MB watching her from a window overlooking the Experiment Floor in the Cryosphere, and she ran away after realizing she had been seen. Samus gave pursuit, and tried to convince the woman that she was here to rescue her, much to MB's denial. They were separated after Samus was attacked by a soldier using the RB176 Ferrocrusher. Later, Samus enters the Bioweapon Research Center in the Biosphere, and the woman is startled by Samus' presence. She runs behind a door and closes it. Samus once again tries to convince her that she means no harm. The woman opens the door, and introduces herself as Madeline Bergman. Samus takes her to sit down, and "Madeline" informs Samus of what has happened on the Bottle Ship. She tells Samus that the Federation was attempting to recreate a special forces unit of bioweapons, based on the heirarchy of the Space Pirates. To that end, the Federation had captured many Space Pirates and created cybernetically enhanced Zebesians to form the core of the force. She explains that "a certain presence" caused the creatures to become ferocious and uncontrollable. Samus assumes that by a "certain presence", she was refering to Ridley. "Madeline" then goes on to say that she sent out a distress signal because she feared the Zebesians would resurrect as real Space Pirates, if left unchecked. Samus finds her statement somewhat questionable, as she doubts whether super-agressive Zebesians would become real Space Pirates. Samus theorizes that without the controling powers of Mother Brain, the Zebesians would become merely a race of feral creatures.

At this point MB leads Samus to a computer terminal, claiming to know of a more dangerous plan. MB explains that the scientists took remnants of DNA found on Samus' Power Suit, which were used to create clones of Metroids and Ridley. Samus asks whether the scientists also created a Mother Brain clone, in order to control the Metroids. MB responds that an artificial intelligence was created instead, which evolved and became self-aware. MB then tells Samus that the Metroids are in a hidden sector called Sector Zero, a recreation of Tourian where Metroids are raised. Samus runs off to destroy the Metroids and MB in the sector, telling "Madeline" to stay hidden. A figure then approaches MB, and she turns to face him before the sound of a gunshot is heard.

Samus heads to Room MW after Sector Zero has been destroyed, where she encounters another survivor. This person claims be Madeline Bergman. Shocked at the strange turn of events, Samus tells her that she already met someone with that name. Madeline reveals that the blonde woman was in fact MB, created to replicate Mother Brain's AI. She was constructed to help regenerate and control the Space Pirate special forces. She originally had an infrastructure after Mother Brain (subsequently resembling Aurora Units as well), but when the scientists got to the point of Metroid creation, she was given a human form to help create a maternal connection to the creatures and successfully control them, inspired by Samus' connection to the Baby. She was dubbed "Melissa" Bergman by Madeline, to help make her feel more human. Madeline also says she felt that Melissa was like a daughter to her.

Madeline explains that MB eventually became corrupt and her personality changed to Mother Brain's as well, and started to go rogue after manifesting emotions, beginning to criticize the work of the scientists. They eventually decided to reprogram her AI, which only worsened the situation. Madeline's presence during her restrainment may have caused the coming personality turn. She takes control of the station, insisting that all humans should be "judged" for their actions. Using her intense brainwaves, she leads all of the bioforms on the ship (excluding Metroids) into killing all the scientists except Madeline, who goes into hiding. Both Madeline and Samus have sympathy towards MB, yet she still hunts them.

After this conversation, MB appears, prepared to attack Madeline and Samus. After Madeline begs her to recall her human side, promising "she'll never fail her again," MB lowers her weapon. She then rushes at Madeline, seemingly pushing her out of the path of an incoming bullet that freezes her. The freeze shot was fired by Galactic Federation soldiers, who run into the room. MB thaws herself and, becoming enraged, summons several Desbrachians to fight off the Galactic Federation soldiers as well as Samus when she tries to intervene, while calling several nearby Ghalmanians and Mighty Griptians for additional reinforcements. Finally, Madeline stops the battle by shooting MB with a Freeze Gun. The soldiers, led by The Colonel, take the opportunity and immediately gun MB down. Melissa is killed and soon afterward Samus is escorted off the ship by Anthony Higgs. As she leaves the Bottle Ship with Madeline and Anthony, images of MB can be seen formed out of space gas while Samus is in deep thought about MB's unfortunate fate; the mentioned images disperse when Samus' gunship passes through it.

Battle

During the battle with MB and her four Desbrachians, Melissa must be targeted in order to end the scenario. To do that, the Desbrachians must be shot aside as Samus is defending Madeline in first person view. The Desbrachians must be shot with whatever tool Samus has, in order to stun them.
