Ridley (Metroid)
Ridley's status within the ranks of the Space Pirates is unclear, with some sources stating that he is the leader of the entire Space Pirate race, whereas others portray him as simply the Pirates' military commander or even a mere enforcer within the Pirate military ranks, subservient to Mother Brain or Space Pirate High Command. Regardless, he is consistently depicted as a ruthless and cunning tactician who never passes up an opportunity to bring his considerable ferocity to bear on the battlefield, opting to overwhelm his opponents with an unwavering onslaught of attacks from his mouth, claws, and tail. He is also incredibly cruel, actively taking pleasure in the killing and torment of others; at one point in the official manga he taunts Samus by claiming he may have devoured her mother's corpse after killing her, and a Space Pirate log entry in "Metroid Prime" notes that being the mainstay of the Pirate security force is "a job he will certainly relish."
Metroid Prime 3: Corruption
The events in "Metroid Prime 3: Corruption" take place six months after "". The game's protagonist, Samus Aran, is a bounty hunter hired to assist the Galactic Federation during its ongoing conflict with the Space Pirates. After facing initial defeat on the planet Zebes during the events of the first "Metroid", the Space Pirates sought to gain power by using a newly discovered mutagen called Phazon. However, Samus managed to disrupt their operations throughout the "Prime" trilogy and ultimately allowed the Galactic Federation to confiscate and replicate their Phazon armaments.
