Ridley (Metroid)
One of Adam's final missions to Samus is to finish off Ridley, whom Adam fears might be more dangerous than the Metroids if left unchecked, and claims Samus is the only one capable of stopping him. However, Samus later discovers his corpse after he is killed, having had his energy drained by the Queen Metroid on the Bottle Ship. His mummified corpse turns up again in "Metroid Fusion" on the BSL station, after having apparently been removed from the Bottle Ship by the Galactic Federation and placed in a sub-zero storage room for further research (potentially into further bioweapon applications). It is later infected by an X Parasite, allowing it to gain the ability to transform into Ridley's likeness, known as . Samus later defeats the Ridley mimic and absorbs its Core-X, regaining her signature Screw Attack. What was left of the cloned Ridley's remains were destroyed along with the X when the BSL station crashed into SR388.
Ridley (Metroid)
Ridley originally appeared in the Nintendo Entertainment System video game "Metroid" as one of the two Space Pirate figureheads charged with protecting Mother Brain at the base on Zebes, where they are cloning Metroids with the intention of converting them into biological weapons. Both he and his counterpart, Kraid, are defeated by Samus. Ridley's remains are collected from the ruins of the base on Zebes and taken aboard the frigate "Orpheon", where he is cybernetically reconstructed as "Meta Ridley". As shown in "Metroid Prime", Samus confronts him aboard the ship and pursues him to the planet Tallon IV, where she hampers his operations to exploit the planet's widespread contamination of Phazon, fighting and leaving him for dead a second time. Mike Sneath, one of three senior character artists for "Metroid Prime", was responsible for designing the Meta Ridley version of Ridley seen in "Metroid Prime". It took him about "20 to 25 days" to model and texture Meta Ridley, citing the wings as having taken a few days of his time, commenting that it took him a while to get the shaders to work to give his wings the appearance of having a "holographic energy." He was not involved with designing the battle with Meta Ridley, which was left up to the game designers. Andrew Jones, the lead concept artist for "Metroid Prime", had little to do with the design of Ridley. The initial design submitted was rejected by Nintendo, while the second design the artists submitted was approved. Steve Barcia, the executive producer of Retro Studios, called Ridley his favorite enemy from "Metroid Prime" due to the quality of the battle and his fan appeal. He added that such a battle was rare for a first person shooter, which helped to set "Metroid Prime" apart.
