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
Mother Brain was also the primary villain in the "Captain N: The Game Master" TV show. A Metroid-lookalike enemy, called the Komayto, was encountered by Pit in "Kid Icarus" for the NES. In "", a fighting game developed by Team Ninja for the Nintendo 3DS, one stage is a replica of the arena in which Samus fights Ridley in "Metroid: Other M" and features both as assist characters; Samus, however, is not featured as a playable character in "Dimensions", as Team Ninja's Yosuke Hayashi stated in an interview that "it would be better to let her focus on her job rather than kicking everyone's butt in ["Dead or Alive: Dimensions"]". A Wii U launch game "Nintendo Land" has a mini-game based on the series called "Metroid Blast".
