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."

As such, Prado takes it hard when his younger brother Oscar is found dead in the house of a drug-dealer nicknamed "Freebo", and even worse when it was found Oscar was a drug addict to whom Freebo sold and that Oscar was in Freebo's debt. Prado even goes as far as to learn the Code from Dexter, and is the second person to witness Dexter in a kill room. With Dexter's guidance he would go on to kill a mob enforcer.
