Metroids are the titular creatures of the Metroid series. They are organisms created by the Chozo. First discovered on the planet SR388 years after their introduction, they were promptly used as a bioweapon by the Space Pirates. Metroids feed on the "life energy" of their prey in a manner similar to the way a leech drains a host organism's blood. Unlike leeches, Metroids leave all of their prey's blood and internal organs intact yet lacking the energy necessary to sustain life.
