Meta Ridley

Meta Ridley is Ridley rebuilt by Space Pirates.

Biography
The Space Pirates recovered his barely living body after Samus Aran wounded him beyond fighting capability on Zebes and added mechanical parts to his form, recreating him into a cyborg and now calling him Meta Ridley. Ridley then began overseeing the Phazon mining and experimentation operations on Tallon IV.

When Samus is evacuating the Space Pirate frigate Orpheon, she sees him break constraints and flee the station. She later sees him flying across Phendrana Drifts and towards the Phazon Mines. She then battles him and defeats him at the Artifact Temple, knocking him into the Phazon infested Impact Crater.

After surviving his ordeal on Tallon IV, Ridley leads the Pirate invasion of Norion by distracting the GFS Olympus and it's fleet of starships with a sneak attack through a wormhole, giving his troops sufficient time to land on the planet's surface. However it is strange that he does not have his wound on his chest that he retains from Metroid Prime during the battle between him and Samus on Norion, wheras he does in Utragia's Leviathan. This has led many to beleive that this is a new Meta Ridley and is killed here.

He then leads the battle to take out the defense base on the planet surface personally. At one point of the battle, Samus and a fellow Federation PED Marine watch helplessly as Meta Ridley single handedly wipes out an entire platoon of Marines on the other side of the base. Ridley also attacks Samus multiple times throughout the invasion, striking her while in morphball form when she is traveling to the last power generator.

Samus later battles Meta Ridley once more after turning the generator back online. Ridley surprises her and tries to tackle her to the ground. However, due to his weight, the two fall into a very deep shaft under the generator. He's much weaker and easier to defeat this time, although this is only due to him being one of the first bosses, and most likely a gameplay choice. She defeats him once again, leaving him to fall down the rest of the generator shaft.

However, Ridley survives the fall through the restorative powers of Phazon in his meta-armor, and is able to escape Norion. He flees to the Pirate Homeworld and becomes fully corrupted in the Leviathan seed.

Samus meets him on the Pirate Homeworld, corrupted and now known as Omega Ridley.
