Creator The Chozo

The Metroid species are genetically engineered by Chozos to prevent the galactic spread of Extremely dangerous X-Parasites. In Chozo language, Metroid means Ultimate Warrior.

Most Metroids are almost equivalent to Facehuggers, expect they attach onto the head of the victim and slowly absorb their life energy.


They mostly have the appearance of green jellyfish-like creatures with what appear to be claws.
