"What's the matter? All I said was that Komaytos look like little Metr—" Non-canon warning: This article or section contains information that may not be considered an official part of the Metroid series in the overall storyline by Nintendo.
Metroid=Mutant, or M=M メトロイド＝ミュータント (Metoroido Myuutanto) is a creature which appears only in Metroid: Zebes Invasion Order. Born from the stolen Metroid capsule, M=M mutated drastically, developing long arms with spears at the ends of them, tentacles, and several massive eyes inside of its main body, with a dramatic increase in overall size compared to Metroids. It can be considered a (non-canonical) predecessor to the Big Metroid seen in Super Metroid.
