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.

The Plutonian, a powerful being once thought to be the world's greatest superhero, has now become its greatest supervillain. He has destroyed Sky City – the metropolis he once protected – and murdered millions of people across the globe. The series starts with the Plutonian killing his former ally, the Hornet, and his entire family. The remaining superheroes, the Paradigm – Bette Noir, Scylla, Cary, Volt, Qubit, Gil, and Kaidan – search for the reason behind Plutonian's change by speaking to his former sidekick Samsara, whom Plutonian lobotomized. Former enemies of Plutonian attempt to work with him but immediately betray him when he offers a way to earn his trust, resulting in a self-destruct of the facility in which they are meeting. The resulting explosion kills Scylla and injures Cary, superhero brothers who are observing the villains. The United Nations offer Plutonian their subservience, hoping to avoid his wrath. The Plutonian takes offense when, after speaking to the Singaporean representative, he realizes that the decision is made out of fear. In response, Plutonian sinks Singapore into the ocean. Meanwhile, Qubit searches for Modeus, the Plutonian's nemesis, using multiple robots designed to look and think like the villain.
