Space Pirates

space pirates are savages that study and mutate metroids into dangerous weapons. The space pirates conduct illegal experimates so that is why the Galactic Federation sends samus to hunt them down in most of the games but the mission usualy turns into a bigger cause. The space pirates were led preiously by Ridley until metroid prime when the pirates betrayed them and chained him up but escaped during the stations breakdown. In metroid prime 3 it seems the pirates have a new leader(dark samus).
