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 (video game)
In addition to common enemies, Samus encounters two bosses, Kraid and Ridley, whom she must defeat in order to progress. Ordinary enemies typically yield additional energy or ammunition when destroyed, and the player can increase Samus's carrying capacities by finding storage tanks and defeating bosses. Once Kraid and Ridley have both been defeated, the player can open the path to the final area and confront the Mother Brain.
