Mother Brain
Metroid character
Mother Brain (Japanese: マザーブレイン, Hepburn: Mazā Burein) is a character in the Metroid video game series by Nintendo. She is the main antagonist of Metroid (1986) and Super Metroid (1994).
Mother Brain has been killed multiple times by the protagonist, Samus Aran. Her Super Metroid design was originally milder than its final version, resembling an "old lady living in an apartment complex" when designed by Toru Osawa. This design was altered by Tomomi Yamane, who gave her an overall more monstrous appearance. She takes the form of a large brain that sits within a jar, from which she controls the Space Pirates on the fictional planet Zebes. Since Super Metroid (1994), she has had a single large eye.
Mother Brain has made several appearances in other media, including the animated series Captain N: The Game Master. Mother Brain was named the 9th-best video game villain by IGN and the 36th-best by the Guinness World Records Gamer's Edition.
Concept and characteristics
Mother Brain is depicted as a large brain with cybernetic spikes, usually contained in a glass tube which Samus must break to attack it, but in the Super NES video game Super Metroid, she is seen in a bipedal form.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Mother Brain”, the useful work is to connect “metroid character” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q2738109. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1986 and 1994.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
