Often considered one of the most memorable Nintendo villains, Ridley has been a mainstay of the series, having appeared (through various incarnations) in almost every "Metroid" game to date (all but "", "Metroid Prime Hunters" and ""). He has also appeared in the "Super Smash Bros." series, however, he had not been made a playable character until "Super Smash Bros. Ultimate" in 2018, making it also the first game overall to have Ridley as a playable character.

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.
