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.
Shao Kahn
Shao Kahn and Darkseid are the key villains in the crossover game "Mortal Kombat vs. DC Universe", though both are playable characters. In the game's plot, a defeated Shao Kahn limps into a graveyard where he meets with his secret ally Quan Chi. They are confronted by Raiden, who uses a lightning bolt on Shao Kahn, which knocks him into Quan Chi’s portal. This event, along with a parallel one between Superman and Darkseid in the DC Universe, results in the creation of Dark Kahn, who serves as the main antagonist in the game. After Dark Kahn is defeated, Shao Kahn ends up in the DC Universe's Darkseid's throne room, where he discovers he has lost his powers. He is promptly imprisoned in the Phantom Zone. However, his powers came back in little time and was able to free himself but also everyone in the Phantom Zone, whom pledge allegiance to Shao Kahn.
