Ridley (リドリー, Ridley) is a character in the Metroid series, and a major antagonist throughout the majority of the series, in which he generally acts as one of the later bosses. A draconic creature hailing from Zebes, Ridley is a vicious, yet highly intelligent member of the Space Pirates, and is one of its most prominent leaders, alongside Mother Brain. He is also the arch-nemesis of the Metroid series' protagonist, Samus Aran.
Ridley, also known by the identifier Geoform 187, is one of the main antagonists of the Metroid series, the other being Mother Brain. In spite of his bestial appearance and fearsome mannerisms, he is by no means a mindless animal, but a high-ranking Space Pirate general that is sapient and, as shown in the comics, capable of speech.
Ridley is directly connected to Samus Aran's past and present. In the Metroid e-manga, he gained enough favor with the Space Pirates that he became one of their figures of highest authority. As such, he attacked and devastated three-year-old Samus's homeworld of K-2L in a raid for fuel and resources, and personally killed Samus's mother when she jumped in to protect her daughter. Unwittingly, he created his own worst enemy in Samus through this.
In Metroid and Metroid: Zero Mission, he appears as the military leader of the Space Pirates and as a boss in the area with his name, and in Zero Mission, the final boss is a robot in his likeness. He, his counterpart Kraid, and all the Space Pirates desired to capture and clone the eponymous Metroid creatures for use in galactic domination. Ridley, however, was surprised to find the little girl from years ago, now a grown woman, having come to fight and kill him.
In Metroid: Samus Returns, Ridley arrives on Planet SR388 as Samus returns to her gunship with the lone Baby Metroid in tow. Here, Ridley’s body has partially healed and he is known as "Proteus Ridley". After a long and hard-fought battle, Proteus Ridley is ultimately left incapacitated on the planet’s surface as Samus and the Baby Metroid leave for the Ceres Station to deliver the Baby Metroid.
In Super Metroid, his body has completely healed and he successfully kidnaps the baby Metroid that Samus found in Metroid: Samus Returns. Driven by intense rage, Samus chases him back to planet Zebes, the Pirate base in Metroid and Zero Mission, and in the process of rescuing the baby, Samus battles Ridley and the other Space Pirate leaders again, ultimately escaping the destruction of Zebes, which marked the final and true death of Samus' longstanding nemesis.
In Metroid: Other M, Ridley is unintentionally cloned via a DNA sample found on Samus' armor after the events of Super Metroid. The result is initially a small white owl-like creature dubbed "little birdie", which Samus later encounters on the Bottle Ship. Later on, it evolves into a quadrupedal lizard and eventually assaults Samus on sight after being assailed by Galactic Federation soldiers. After escaping the attack, the mysterious creature evolves its final and most recognizable form. Samus then re-encounters this reborn Ridley inside the Geothermal Power Plant in the Pyrosphere area of the Bottle Ship. Having thought she had eliminated him for good at the destruction of Zebes, his presence drives such a shock into her that she is becomes unable to speak or move, until Anthony Higgs supposedly sacrifices himself trying to protect her. Enraged by the loss of her friend, Samus attempts to kill Ridley once more. Having suffered heavy injuries from the battle, Ridley flies away. He is later attacked by the reincarnated Queen Metroid, being left as a lifeless husk.
In Metroid Fusion, the body of Ridley's clone, cryogenically frozen, reappears on the Biologic Space Labs research station, which Samus encounters halfway through her mission there, to witness it shatter, while an X Parasite mimicking him exits the body. Samus later encounters the X-mimic becoming "Neo-Ridley" and defeats him, presumably for the final time.
Ridley appeared on Planet Zebes, flying in the background. His appearance is based off of his Super Metroid sprite.
Ridley has a cameo in the opening movie of Super Smash Bros. Melee, fighting Samus, when Samus jumps over him and shoots several missiles. As the opening movie was part of the game's initial reveal, this scene led to fan speculation that Ridley would be a playable character, though this ended up not being the case. Like in Super Metroid, Ridley is carrying the baby Metroid's capsule, though unlike in Super Metroid, Samus has both the Varia Suit and Missiles.
The head of the Space Pirates on Zebes, Ridley soars through space on wicked wings. Ridley may look like a mindless monster, but he's actually quite intelligent. After the SR-388 incident, where Samus captured the infant Metroid, Ridley took the Space Academy by storm, annihilating the complex and taking the Metroid back.
A remix of Ridley's theme from Super Metroid and Meta Ridley's theme from Metroid Prime both appear in Brawl. In addition, Ridley's lair in the Metroid series, Norfair, is featured as a stage.
Hacking of Brawl's reveals incomplete Assist Trophy data for Ridley, though he is not available as such. Presumably, Ridley was initially planned as an Assist Trophy, but was instead included as a boss.
Role in the Subspace Emissary
Ridley is the fifth boss in the Subspace Emissary. Samus and Pikachu must fight him at the end of the Research Facility II. In the cutscene prior to the battle, Ridley ambushes and grabs Samus, flying upward and scraping her along the walls. Pikachu breaks Samus free from Ridley's grasp using Thunder. In the first battle, Ridley has higher health and uses moves ranging from claw swipes to a move similar to Rayquaza's ExtremeSpeed to a tail swipe across the entire stage. Meta Ridley, his form in Metroid Prime, later attacks Donkey Kong, Diddy Kong, Captain Falcon, Olimar, Samus, Pikachu, and R.O.B..
Ridley spends most of his time in the air over the abyss. Characters with strong aerials have an easier time, but in a pinch up-smashes can be used. Most of his attacks are either relatively slow or well telegraphed, thus staying alert can help the player avoid a lot of damage. The hardest attacks to dodge are his claw sweep (not his tail sweep) and loop-de-loop, but by paying attention to his attack order they can be predicted.
On higher difficulties of Subspace Emissary, defeating Ridley usually earns something valuable.
Like all bosses Ridley can be controlled with hacks in Boss Battles Mode. The start button will, like all bosses, self-destruct him.
Origin of Attacks
Most of his attacks are completely made up for Brawl; however, there are a couple attacks that are somewhat retained: The attack that Ridley does when he flies to the background of the stage and tries to ram into the player looks very similar to how Ridley flew away in the beginning of Super Metroid. Also in Super Metroid, Ridley will often use his tail as a weapon by whipping it at Samus. In Brawl, Ridley does use his tail as a weapon, but not as a whip.
HP and damage taken
Like all bosses in Brawl, Ridley gains an additional ×0.6 damage resistance modifier when fought in co-op mode, effectively gaining 67% more health. This modifier is applied whenever the second player is in-game, and is no longer applied if the second player loses all their stocks.
The leader of the Space Pirates. He looks like a pterosaur but has high intelligence and a brutal nature. He plans to steal the baby Metroid from Samus for his own use. Ridley utilizes wings for a full range of flight and attacks with fireballs from his mouth and whips of his tail. As the culprit behind the murder of Samus's parents, the connections with Samus run deep.
When Sakurai first revealed the Pyrosphere stage for Super Smash Bros. for Wii U, he mentioned that a character from "Samus' past" may appear at any second. Furthermore, Ridley's shadow appeared on the stage in the April 2014 Nintendo Direct, in the section which discussed the Yellow Devil's role as a stage boss on Wily Castle. Ridley was ultimately confirmed to appear as a unique stage boss in the Super Smash Bros. for Wii U 50-Fact Extravaganza, over a year after the Pyrosphere was revealed.
Like Samus and Zero Suit Samus, Ridley matches his physical appearance from Metroid: Other M. In battle, Ridley will appear and attack players. He will use attacks based on where opponents are standing. Unlike other stage bosses, however, damaging Ridley enough will cause him to fight alongside the fighter. Damaging him enough after he joins a player's side will KO him, adding another point to the player's KO total, even if he is on the player's side. Ridley may gather energy from the purple vats under the ledges, increasing his strength. Curiously, his stock icon (used in the KOs row of the results screen) is of his Brawl artwork.
Super Smash Bros. for Nintendo 3DS marks Ridley's first complete absence from a Super Smash Bros. title.
As a playable character
Main article: Ridley (SSBU)
After many years appearing only as a boss, Ridley finally makes his debut as an unlockable newcomer, being revealed during the Nintendo E3 Direct on June 12, 2018. His inclusion as a playable fighter was largely facilitated by popular demand both within the previous installment’s Fighter Ballot and afterwards, particularly in the West.
Much like Zero Suit Samus in both Ultimate and its predecessor, Ridley uses a composite design original to the Smash series; in this case, he is primarily based on Super Metroid, with some embellishments and elements from Metroid: Other M, resulting in a more realistic and detailed design than his Brawl boss appearance. Meta Ridley is featured as an alternate costume for Ridley. An official Ridley amiibo was confirmed the same day and launched alongside the game itself.
