"It was different than the other Metroids. Though similar in appearance, something was fundamentally different."

Metroid=Mutant (メトロイド=ミュータント Metoroido Myūtanto?), or M=M, is a mutated Metroid which appears only in Metroid: Zebes Invasion Order.

Born from the stolen Metroid capsule, M=M mutated drastically, developing large crustacean-like limbs; long tentacles; several massive eyeballs inside of its main body; and a dramatic increase in overall size compared to other Metroid larvae. Samus Aran can run into M=M at different points throughout the book, with the choice to fight or flee; sometimes, M=M will flee itself.


  • M=M can be considered a non-canonical predecessor to the Big Metroid seen in Super Metroid, since each specimen is a supersized mutant Metroid that was formerly contained in capsule stolen by Space Pirates. However, it is unknown if Zebes Invasion Order had any influence on the development of Super Metroid.
