Ridley (Metroid)
Ridley returns in his Meta form once again in "", where he, along with the Space Pirate legion under his command, are corrupted by Dark Samus. He encounters and battles Samus on Norion, a Galactic Federation-occupied world, and the two fight while free-falling down an air shaft. Ridley is later supercharged with Phazon, becoming "Omega Ridley", and is charged with guarding the Leviathan Seed on the Space Pirate homeworld. He is confronted once again by Samus, and despite being defeated, he survives the fight and is later cured of his corruption after Dark Samus' defeat later on. Between the "Prime" trilogy and "", the Space Pirates reorganize on Zebes and hatch another plan to clone and weaponize the Metroids, while Ridley gradually begins to regenerate from his past injuries, gradually shedding his cybernetics. In the remake of the second game, "", Ridley, in his semi-regenerated form of "Proteus Ridley", attacks Samus on SR388 to steal the last remaining Metroid. Samus and the baby Metroid work together to defeat Ridley.
Metroid
"Metroid" was designed to be a shooting game that combined the platform jumping of "Super Mario Bros." with the non-linear exploration of "The Legend of Zelda" and a distinctly darker aesthetic. The name of the game is a portmanteau of the words "metro" (as in rapid transit) and android, and was meant to allude to the mainly underground setting of the first game as well as its robot-like protagonist. Halfway through development of the original "Metroid", one of the staff said to his fellow developers "Hey, wouldn't that be kind of cool if it turned out that this person inside the suit was a woman?", and the idea was accepted. Ridley Scott's 1979 science-fiction horror film "Alien" was described by Sakamoto as a "huge influence" after the world of the first "Metroid" had been created. The development staff was affected by the work of the film's creature designer H. R. Giger, and found his creations to be fitting for the "Metroid" universe. In recognition of this, a character was given the name Ridley, after director Scott.
