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."

After a mysterious rival boss started muscling in on her territory she decided to hire several mercenaries to enforce her rule, two of these mercenaries were Shrapnel and Black Spider. However Black Spider was arrested by the Flash for robbing a diamond exchange, and Shrapnel was arrested after murdering the Road Reapers. Soon after this another pair of mercenaries were apprehended by the Flash- Trigger Twins, this prompted Copperhead to open negotiations with the mysterious crimelord whom she discovered was Captain Cold of the Rogues, in order to find away to defeat the Flash.

The Flash was able to save her after he apprehended Cold, but without any evidence of her involvement she was allowed to walk free.
