    The Main Two 

Samus Aran

"Protecting the protectors is my duty."
Voiced by: Jennifer Hale (Metroid Prime series), Alesia Glidewell (Super Smash Bros. Brawl), Jessica Martin (Metroid: Other M English), Ai Kobayashi (Metroid: Other M Japanese)

"In The Galactic Federation, only one being in a million hopeful applicants are qualified to join the Federation Police Force. The annals of their history tell of a woman who not only undertook the specialist training but completed the course in record time, graduated first in her class and became the youngest Police Officer ever to be promoted to the Elite Star Tracker Squad!"
The Coming of a Hero — Nintendo Power Comics System

"The Cosmos. In the vast depths of the Universe, the history of humanity is but a flash of light from a lone star. The life of a single person should be lost in space and time. But among the stars, there is one light that burns brighter than all others. The light of Samus Aran. Her battles extend beyond her life, and etch themselves into history."
Metroid Prime's Intro Narration

Samus Aran created history in 1986 by being the first video game hero (or in her case, heroine) to be a female. Samus Aran is the main protagonist of the series and considered to be an icon of strength within her own universe. She's regarded as the finest killer alive in a society spanning at least more than one inhabited galaxy under a still as yet unseen umbrella nation. Which is comprised of trillions of individuals and has waged a perpetual war with nomadic inter-stellar brigands and all manner of criminal scum for the near entirety of her long career. As she is held in such high regard to the degree that he, she, it, is often mistaken for an urban legend or patron saint of bounty hunters, though supplemental material reveals her to be a woman of humble origins and surprising means. Although seemingly remorseless and without scruples, she possesses untold benevolence and humanity despite her violent profession and strives to be a force for good, spreading light into the darkest corners of space. Underneath her armored suit, she's also drop dead gorgeous, and regularly recognized as one of the sexiest females in video games.
"Are you not afraid? Those who don't worry about dying in the future won't fight for their lives in the present."

"Remember... I can do a lot worse than send you to prison, boys!"

  • Action Girl: The first major example in all of video games. And arguably the definitive example.
  • Amazonian Beauty: Over six feet tall, defined like Bruce Lee, clad head to toe in armor, and one of Nintendo's biggest bad asses.
  • Arm Cannon: Her primary weapon among a veritable arsenal.
  • Badass: Unbelievably so. She's defeated legions, hunted impossibly dangerous quarries and walked over every nightmare that dares cross her path and then some. She wiped out the Universal threats embodied in the Metroids, Gorea, the X, Phazon and the Ing. Battled an NGO Super Power for her entire life, reducing them to a bad memory and takes on her family's murderer every other week; eventually wiping him from the face of existence with an Earth-Shattering Kaboom. And that's what she get's up to in her spare time.
    • Badass Bookworm: Samus has a strong engineering background and her handwritten notes in her log book very much implies extensive knowledge in the fields of biology, physics and chemistry. After all, she was brought up and educated by enlightened Precursors.
    • Badass Cape / Caped Mecha / Coat Cape: Aran sometimes wears one over her armour. It's awesome.
    • Badass Longcoat: Owns one in the manga, and yes, she can still kick your ass with it. Plus, a nifty wide brimmed sun hat that would make the Queen of England jealous to boot.
    • Empowered Badass Normal: By way of her Chozo and later Metroid genetics.
    • Heartbroken Badass: So far her family, adoptive family, imprinted Metroid infant, mentor and many close friends have all been horrifically killed, with her often unable to do anything about it.
  • Bag of Spilling: In the Prime trilogy: Samus either loses all her previous weapons or is forced to seek out new ones.
  • Batman Gambit: She periodically overcomes every counter-tactic the Urtragian Space Pirates throw at her, always through intellectual application and her own warrior instincts. Taken to hilarious heights in the 'Captain N Comics' when she, at one point, caught off-guard by 'Big-time' Brannigan, sabotages her own gun to back-fire, knowing he'll want the Dramatic Irony of finishing the best bounty hunter in the guild with her own side-arm. He's promptly maimed and Aran escapes. Another time, she tricks Mother Brain into handing over a more substantial bounty for turning on her allies, then she promptly betrays her, steals the Applied Phlebotinum that was the main objective of their mission and rescues her friends on top of all that! Leaving Mother with nothing! Fittingly, her character is more of an Expy combination of both Han Solo and Boba Fett.
  • Beauty Mark: Naturally. Previously hinted at by Yoshio Sakamoto who claimed to be the only one who knew where it was. Its location is finally shown in Other M: under the left side of her lip.
  • Body Horror: She goes through this fighting the corruption in Prime 3. When was the last Nintendo game in which you saw the protagonist vomiting up radioactive sludge? Also, if she overloads on Phazon in Hyper-mode, she becomes fully corrupted.
  • Boobs of Steel: From Zero Mission onwards she's been a rather well-endowed bad-ass, something that the fan-base has certainly noticed.
  • Bounty Hunter: Purportedly her profession, but some overseas developers think Nintendo's refusal to include actual bounty hunting in the games indicates it's a translation screw-up. Despite this, they seemed to have no problem with the manga showing her hunting bounties.
  • Bio-Augmentation: Her DNA is as modular to genetic upgrades as her armour is to technology, as she was infused with Chozo DNA and later Metroid DNA. How mighty are her genetic gifts do you say? In Metroid Prime, scan data of Zebes reveals it to have both an incredible mass and gravitational pull. As Samus grew up on Zebes, with Chozo DNA to boot, simple math performed by fans reveals this gem: Suitless, Samus can lift 66.5 TONS on Earth.note 
    • This, however, hinges on the assumption that the developers knew the actual significance of the immense numbers they put into those scans if they were put into proper calculations - common sense would recognize such insane scaling (which would make Samus over 950 times as strong as a normal human!) as a case of Writers Cannot Do Math...
      • Well, the thing is whether or not the writers were conscious of what these numbers imply, it's a moot point because Samus (as far as we know) never visits worlds with gravity comparable to Earth. All of the enemies she's fighting are adapted to the same intense gravity as she is; since she's only compared to similarly strong opponents, there aren't any massive gaps in strength like there would be if she went to Earth and fought something there.
  • Building Swing: The Grapple Beam in Super and Grapple Lasso in Prime. This becomes less important with the Space Jump/Screw Attack, but Prime 3 gives the lasso more functions to keep it relevant.
  • Casting Gag: During Samus' younger flashback scenes in Other M, her younger self looks a lot like Deunan Knute from the Appleseed CGI films. Incidentally, Samus is voiced by one of Deunan's Japanese VAs.
  • The Chosen One: According to Chozo prophecy and the carvings on Tallon IV.
  • Combat Pragmatist: Fond of shooting people at point-blank range when getting into physical grapples and applying the most overwhelming amount of force possible to end a fight quickly. In Super Metroid, she defeats Draygon within seconds by conducting electricity through the grapple beam and through herself, flash-frying the monstrous crustacean.
  • Cool Ship: Her Gunship. With it's own remote controlled auto-piloting functions, industrial grapple beam, missile silos, prisoner containment cells, array of beam weapons and even capable of self-repair and enduring ridiculous levels of combat damage and even the corrosive properties of Phaaze's atmosphere.
  • Cowboy Cop: In the prequel comic, Samus was part of a cowboy cop trio up until she left the force to become a solo bounty hunter on General Adam Malkovich's suggestion.
  • Cultured Warrior: Explores uncharted territory, muses on war, peace and her place in the universe, collates zoological databases on a variety of exotic flora and xeno-fauna, is an evaluator of her own and other's morality, translates ancient advanced alien scriptures and seems to practice a form of Instrumentalist Philosophy.
  • Determinator: An absolute given, considering her suit's defences rely on maintaining a zen level of focus during battle, which doubt can cripple. But one particularly impressive display of willpower she displays is in Metroid Prime 3. She staves off Phazon Corruption longer than any of her fellow bounty hunters, in spite of being given the largest dose of radioactive venom by her arch-nemesis. And even retains her mind when at its very origin. With the poison coursing through her veins she descends into the core of the planet Phaaze and wipes the floor with her dark doppelganger, endures the cancer being (unimaginably painfully) purged and somehow manages to escape back up to the surface before the world blows apart.
  • Doom Magnet: Inherited from the Chozo. Person, planet, species, once she gets there, if they haven't already suffered tremendously (and they often have), they will. Not necessarily by her design or intent, mind you, but it inevitably happens anyways.
    • Subverted with the Luminoth, as she actually does help them out with no negative side effects to them in the long run.
    • And the Elysian star charts in Corruption show that the native life on Tallon IV is thriving since Samus ended the Phazon spread.
  • The Dreaded: The Space Pirates probably tell their spawn stories of the 'Accursed Hunter' that stalks their kind. They fear and loathe her above all else.
  • Early Installment Weirdness: In the original Metroid, her aspect was unusual at best. Especially outside her suit where she has an almost bare outfit and has green hair when wearing the Varia Suit. When you play as her outside her suit, she can use the majority of her suit's abilities including her Morph Ball function.
  • Elemental Powers
    • An Ice Person: Her most prominent power in terms of taking on Metroids. Flipped on its head in Fusion, where Samus fears the Ice Beam.
    • Playing with Fire: The Plasma and Nova beams are depicted as such. While not exactly fire, per say, they essentially act as such in the Prime series.
    • Shock and Awe: What the Wave Beam is mostly portrayed to be. Though in actuality it can diffuse through materials and hit opponents behind cover.
    • Light 'em Up: The Light Beam from Prime 2. An effective solar ray. Or even the wandering matter of the Luminoth's planetary energy that sustains them.
    • Casting a Shadow: Also the Dark Beam from Echoes. This will ruin anyone's day with concentrated evilness from the Dark Dimension. It hurts a being of pure Phazon.
    • Pure Energy: Essentially what her Power Beam is. It Vaporizes targets in Prime 3.
    • Make Me Wanna Shout: What the Annihilator beam becomes when charged. It temporarily cracks reality.
    • Yin-Yang Bomb: What the Annihilator beam, and especially its missile combination the Sonic Boom is, in addition to the above; being a matter-antimatter weapon and all.
  • Expy: Directly stated to be one of Ellen Ripley, another strong female sci-fi protagonist who battles cosmic monstrosities. She's also occasionally considered a Distaff Counterpart of Boba Fett, another space-faring Bounty Hunter with a Cool Ship, a full suit of armor, and lots of weapons and gadgets.
  • Fear Is the Appropriate Response: What makes Other M slightly easier to swallow is this trope. Samus informs a would be ally that a warrior only fights their hardest when controlling and utilizing their fear of death. Not suppressing or trying to deny it.
  • Femme Fatale: As beautiful as she is dangerous. The fandom plays up this aspect of her predatory nature.
  • The Fettered: She has a code, it has a lot of leeway.
  • Flash Step: You can do this in-game as a strafe mechanism but the most memorable one has to be in the supplemental material. it's accompanied with an insane bullet catch when the hostage's face is two feet away from the muzzle of the weapon. Sam manages to shoot the Pirate at the same time.
  • Friend to All Living Things: Shown to concern herself with the well-being of wildlife she encounters during missions.
  • Genius Bruiser: She knows a great deal about mechanics and electronics, evidenced by her working circuitry in a few games and by designing her own gunships, doing precision welding jobs, energizing dead systems, hell, just being able to operate that walking death mobile she's clad in has to count — but the stand-out moment for Aran has to be her constructing a Chozo WMD called a Theronian Bomb out of a floating city's infrastructure, rewiring the engines to float a section of said city over to the Leviathan Seed's shield generator, all the while fending off dozens of pirate drop ships before leaving in a sabotaged escape pod that she quickly repairs; the munition is dropped and the atmosphere is ignited in nuclear fire.
  • Good Is Not Soft: Quintessential. The first time she spares the life of a child-enslaving pirate overseer; is so she can interrogate him.
  • The Gunslinger: The auto-lock is not technological. Revamped straight over into Improbable Aiming Skills in the manga. When five pirates are about to execute a girl. They all fire simultaneously while encircling her. Aran deflects all of their shots away with her own beam, With four inhumanly quick shots of her own.
    • Also an accomplished quick draw. And by accomplished, we mean she can take down multiple opponents and make it look like a single shot. This, with a weapon that's effectively an artillery piece.
  • Hair of Gold, Heart of Gold: A gorgeous blonde, and about as kind of a mercenary as you could possibly know. She has to be an optimist to endure what she's been through.
  • Half-Human Hybrid: In the end, she's anywhere from as much as 95% human to as little as 10%. For most of the series, she's a human with Chozo traits that supersede human maximum potential, but then Fusion brings in the vaccine made from the infant Metroid Queen's stem-cells; which her unique organism adapts much in the same way her suit can adapt modular, alien technologies in order to fight of the infestation. From there, fans debate about whether exposure to absorbed X Parasites when recovering her arsenal has messed up her genes further; Nintendo itself has been silent on the matter. The game shows that the X Parasites were destroyed by her Metroid vaccine. Metroids eat life energy, not solid food, so she's not integrating absorbed X physically into herself, but its implied that the X she gets abilities from had them biologically, rather than mechanically, so fans understandably still argue.
  • Happily Adopted: Her second family foisted her with an unforgettable legacy. Defend the Universe as the Entrusted One, at her request they allowed her to claim their nearly lost arts of destruction in order to avenge her home and birth parents against the forces of chaos. It's quite clear that this orphan received the best break possible after such a rotten start to life, cherished by both her foster-fathers in their dying moments as the supreme exemplar of both humanity and the Chozo.
  • Heroic BSOD: A horrific one in the e-manga. When Ridley forces her to remember that fateful day he brought devastation to K-2L. How his men butchered her childhood friends and how he roasted and ate her mother! She loses control of the mental link between her armour and goes into a catatonic trance, hyperventilating, eyes rolled into the back of her head and screaming repeatedly to be killed by her own allies as her fear is all-encompassing and overwhelming. Although she later 'overcomes' this breakdown in about the most cathartic way possible she is implied to still suffer PTSD induced nightmares many years after the fact.
  • Heroic Build: Sadly zigzagged. Most apparent at the end of Super and Fusion.
  • Heroic Willpower: As seen in Metroid Zero Mission and Other M, Samus' Power Suit manifests though inhuman levels of willpower and concentration, and can dissipate if she falters. Yoshio Sakamoto compared her losing her suit to a salary-man losing his tie in a bullet train.
  • The Hunter: Literally. In Metroid's Universe she'd be the example under the noun in the dictionary.
  • Hyperspace Arsenal: Her suit can hold over 200 missiles even on the NES game.
  • Innocent Fanservice Girl: To an extent, as she was raised by aliens. Non-mammalian aliens, at that. Not to mention that she's not entirely human herself anymore.
    • One theory as to why most of her outfits besides the ubiquitous powersuit are so skimpy is because she's uncomfortable wearing too much, rather than a deliberate attempt to look seductive. Because the suit links directly with her nerves it feels like her own skin and thus she's gotten used to feeling naked most of the time.
  • The Lad-ette: Downplayed. While Samus isn't often seen engaging in overly "frat-boy-ish" behavior, she wears a traditionally masculine suit of Powered Armor and can kick ass with the best of them. Except in Other M, Samus has almost no feminine traits apart from her physical appearance, and can even be seen hanging out at a bar in one of the ending scenes of Zero Mission.
  • Lady of War: On the contrary to the prior point, she cracks skulls and does it with obscene poise and grace.
  • Le Parkour: Supremely gifted at navigating treacherous environments at a constant sprint. As well as performing an assortment of jumps, flips and tumbles that would make an Olympian gymnast green with envy. Mei Ling in Smash Bros. Brawl can only refer to her as a "Super Athlete" and she's damn right.
  • Lightning Bruiser: Can plow through enemies with mach speed shoulder charges, possesses enough razor sharp reflexes to dodge gunfire while stationary and can tether, hook line and sinker, then beach a gigantic alien beast that can swim in lava. Even without the suit she can jump about forty feet straight up in the heavier gravity of Zebes. Imagine what she could do to you if she kicked you while on Earth.
  • Luke, I Am Your Father: In the manga, Grey Voice turns out to be the donor for Aran's infusion of Chozo DNA.
  • Made of Iron: Due to her Chozo heritage and Zebesian upbringing. She can take shots for the team that would cause a lesser hero to crumple in one. She can stand multiple times after having been hit by Mother Brain's rainbow hyper beam. And she will fight and win battles with a drop in the tank to spare.
  • Mama Bear: Ask Mother Brain. Oh wait, we can't, it suffered Samus' rage after it killed the Super Metroid while protecting its perceived mother figure.
  • Mike Nelson, Destroyer of Worlds: Basically, everything she steps on triggers a Self-Destruct Mechanism.
  • Ms. Fanservice: Oh, most definitely. She's undeniably gorgeous and doesn't mind peeling off all that armour and enjoying the breeze. Just don't think she's another pretty face... Or you'd find yourself paying for it, dearly.
  • Nerves of Steel: If courage has a name, it must be Samus Aran.
  • Never Trust a Trailer: All promotional material for the first game outright lied and said that Samus was a male cyborg. This extended to the game manual itself. Of course, this was to preserve the surprise at the end.
  • Nonchalant Dodge: The fact that she can pull these off, along with her Stone Wall levels of health, makes her nearly invincible.
  • Not Quite Flight: The Space Jump in the 2D games lets Samus jump at any time, even in midair; downgraded to a Double Jump in Prime, but then you get the Screw Attack in those games and she's back to jumping canyons. The Shine Spark also qualifies.
  • One Woman Army: She was called in to Zebes to solve what orbital bombardment could not.
  • Only the Chosen May Wield: Aran's second Power Suit, attained in the Zero Mission epilogue after her first was destroyed.
  • Parental Abandonment: Certainly not by their own choice. Both Rodney and Virginia Aran go down in ways that make James and Lily from the Harry Potter books look like pansies. Thanks for that, Ridley.
  • Partial Transformation: In the manga, Samus is capable of manifesting her suit's Arm Cannon without the rest of the suit.
  • Person of Mass Destruction: Possesses enough power to level almost anything, man, beast, army, world, ghost or Physical God.
  • The Pirates Who Don't Do Anything: Is a bounty hunter who is yet to be seen doing any actual bounty hunting. Her work in-game would suggest she's more like a mercenary.
    • She claimed to be searching for a bounty in Super Metroid, so it could be assumed most of the games we play are special situations where someone contracted her, or she's just sidetracked and she would be hunting bounties if not for it.
    • In Metroid Prime 2, Samus actually was hired by the Galactic Federation for a search-and-rescue mission for the missing troops that had crash-landed on Aether. Of course, within the first five minutes of the game she learns that they've already been wiped out. Everything after that was of her own volition.
    • For Metroid Prime 3, Retro Studios initially planned for Samus to do some actual bounty hunting. She'd get a list of possible jobs to do, earn rewards, and use the cash to buy upgrades for her equipment. Nintendo didn't like the idea, and after some back-and-forth, Retro realized there was a language issue, and that "bounty hunter" isn't exactly the best description of what Samus is supposed to be. The Retro developers started joking that she was a "pro-bono hunter" instead.
  • Powered Armor: Her Power Suit is one of the most famous examples in all of media. A Chozo-designed cybernetic battle exo-skeleton of quantum-locked, psionically summoned armour that is synchronized with her very being and can adapt to incorporate all known (and some unknown) weaponry. It also provides energy shielding, protection from lethal environments, enhanced strength and uncharted tactical scanning capabilities.
    • Clothes Make the Superman: Although she is still inhumanly agile and monstrously strong outside the suit, Samus is unable to take down a lowly Space Pirate trooper without its help. Averted (possibly even inverted) in Super Smash Bros. for Competitive Balance reasons. That might be because she was basically unarmed (that paralyzer doesn't really count) without it.
    • Cool Helmet: Especially in the Prime series, where it resembles a V-shaped, upside-down bird's wings.
    • Life Energy: This is apparently how the health and ammo pickups work, according to the first game's manual. The Prime series let you find them from crates too though, suggesting it might just be general matter/energy conversion (or that Retro wanted to make things easier)
    Even the Space Pirates fear his space suit, which can absorb any enemy's power.
    • This is seemingly how Samus gets the hyper beam and Phazon suit, both involved an almost deceased monster falling on and getting partially absorbed by the suit.
    • Tron Lines: Kelly green for the Varia suit, cerulean for the P.E.D. suit.
  • Protectorate: At least on paper. She trained as a warrior ultimately to defend others from what she had to endure but she is not averse to proactively tracking down evil and annihilating it. And a girl has to make a living somehow.
  • Raised by Natives: Rescued, nurtured, trained and loved by the last remnants of the Chozo.
  • Ramming Always Works: While she's best known for her various beam and missile weapons, the Screw Attack and Shine Spark are some of Samus' most powerful attacks.
  • Really 700 Years Old: Inferred. Even if she's not this in the timeline that would have you believe she became famed across multiple galaxies within twenty years. Her Chozo genetic properties ensure she won't be dying peacefully in her bed any time soon.
  • Red Baron: Of all her prey. Of all her foes, the Space Pirates deem her as the one and only being regarded enough to bear the title of The Hunter. In a universe full of them!
  • Remember When You Blew Up a Sun?: In Echoes, logs left by the troopers mention the two planets full of Space Pirates she's blown up. One of the ones who mentions the story thinks that the act was too much for a single human to accomplish...
    • Although it's worth pointing out that, chronologically, she had not yet blown up any planets when that comment was made. As far as we know...
    • Then again, it's a possible the trooper meant the events of Zero Mission and Metroid Prime, where she attacked their bases directly.
  • Roaring Rampage of Revenge: Implied that she has a very massive one against Mother Brain and Ridley.
    • In Corruption, the final battle on Phaaze is implied to be this as well, considering Aran's reactions to each of the Hunters' deaths, making it quite clear that by the time the final fight ensues, she's ready to rip the one responsible (Dark Samus) apart.
  • Rocket Jump: Bomb jumps; as bombs float in air, it can be done at least twice in all games, and taken to ridiculous levels in some. Power Bombs can be used for this effect too in the games where they aren't explicit room cleaners. It's implied that the jets on her back sometimes do this as well.
    • Being immune to her own explosives is important, as it helps Samus remove Personal Space Invaders from her suit. (for competitive balance reasons, Samus can be hurt by the explosions of some of her own weapons in Hunters)
  • Rolling Attack: The Boost Ball and the shine spark can be used in morph ball mode in Zero Mission.
  • Samus is a Girl: Trope Namer, as the first game used this trope as a bonus for players to find out.
  • Scarily Competent Tracker: All but outright stated. She tracks the Pirates that flee from Zebes to Tallon IV across space. Also, complete the scavenger hunts in each chapter of the Prime trilogy and you will most definitely feel like one of these.
  • Screaming Warrior: Only once, and in the manga at that, but what a moment it is. After obliterating Ridley for the first time and avenging her mother, her childhood home and her adoptive father, Samus lets loose over twenty years of pent-up primal fury with a roar of vindication and release. It. Is. Glorious.
  • Shell-Shocked Veteran: Was suggested to have PTSD in the manga (though not officially diagnosed, as there was another theory), and according to an interview with Yoshio Sakamoto and Team Ninja Samus is poor at coping with her life's problems as well.
  • Sherlock Scan: Thanks to her Scan Visor, though considering the notes seem to sometimes be written by Sam's own hand — and that time pauses upon finishing the evaluation...
  • Shoulders of Doom / Giant Poofy Sleeves: Since Metroid II on the Game Boy couldn't use color to differentiate between the different suits, the Varia suit was given big honking shoulders to distinguish its sprite from the regular Power Suit. The design has carried over since then to every subsequent game in the series.
  • Shrouded in Myth: In the very first game's instruction manual, Metroid's Samus Aran is described as being "shrouded in mystery", supernaturally skilled, and Nigh Invulnerable thanks to a plethora of cybernetic upgrades, encased in a suit of Powered Armor that's the terror of every law-breaker in the universe, and with his, her or its true form known to no one. Of course, when the armor finally comes off at the end of the game, the galaxy's most famous Bad Ass turns out to be a rather attractive blonde woman.
    • The legend also winds up oddly inverted, according to the logs of Metroid Prime 2. Some of the Federation Marines apparently consider the various exploits of Samus Aran, and even her very existence, to be only slightly more credible than bed-time stories:
    PFC Crany: Last night at chow, Angseth starts talking about some bounty hunter and how she blew up a planet full of Space Pirates. I told her I didn't believe in fairy tales like that, and she took it personal. I just find it hard to believe that one person took out an entire Space Pirate base, that's all. But if she wants to believe in this Samus, or Bigfoot, or Santa Claus, she can.
    • The Space Pirates, not to be outdone, have grown Samus into their cultural mythology as a one-woman demonic grim reaper. Every game in the Prime series features an Apocalyptic Log sequence in which the Space Pirates describe the impending horror of a raid by "The Hunter." To clarify, the Prime series shows numerous other bounty hunters, and implies that there are many more; that it is Samus alone that they call the Hunter shows how terrified they are of her.
  • Signature Move: The fabled Screw-Attack... It really needs a title update.
  • The Silent Bob: In the Prime trilogy.
  • Sphere of Destruction: Power Bombs in the 3D games. They are ovals in the 2D ones.
  • Spider-Sense: Prime reveals that the heads up display of her helmet includes indicators of movement and energy sources outside of her field vision, allowing Samus to react to things she cannot immediately see (Prime 2 and 3's cutscenes provide third person demonstrations even if the player never figures it out). Apparently supplementary materials suggest she has Chozo physic senses to fore-warn her of imminent danger and trigger fantastic reaction speed but the only places any thing like this comes close to being demonstrated are in the manga and Other M.
  • Spy Catsuit, Form-Fitting Wardrobe, Sensual Spandex: The Zero Suit. At its introduction it was the most modest clothing she had worn outside of her Power Suit.
    • Combat Stilettos: The Zero Suit has them in Other M, which ironically enough were previously discouraged during Zero Mission's design process.
  • Standard Powerup Pose: Does a painful looking variant in Prime 3 when empowered after Leviathan Guardian bosses.
  • Statuesque Stunner: According to the Super Metroid Player's Guide, she's supposed to be 6'3 and 198 pounds outside her armor. She's significantly shorter than the average male human in Other M, but in the Prime games, she's just as tall or taller than the Federation personnel and about the same size as most of the bounty hunters (except the three from Prime 3), so it's easier to believe there.
  • The Stoic: Until Other M came along...
  • Stun Gun: Her Paralyzer, which she uses for protection when not wearing her armor. Brawl adds a whip mode.
  • Super Soldier: Sam's pretty much got the complete Super Soldier package, being adopted by the fantastically advanced yet consciously going extinct Chozo, who infused her with Chozo DNA to gain fantastic speed, strength, agility and sensory capacity, trained her as the last Defender (read: legendary universe-saving warrior/judge figure) and equipped her with a modular suit of Powered Armor that's the envy of the galaxy. On top of this, she's largely fueled by a burning desire to get back at the Space Pirates who trashed both of her home-worlds and left her orphaned twice over. If there's a better warrior in the series' galaxy, we haven't seen him, her or it yet.
    • Not only that, she later gets infused with Metroid DNA, and has also been exposed to the highly volatile substance Phazon repeatedly. Additionally, her aforementioned Powered Armor can utilize virtually any weapon or technology it comes across, can hack into even the most secure networks just by looking at it, and can determine the weakness of almost anything, animal or mineral, by the same process.
    • For bonus points, the word "metroid" in the Chozo language means "ultimate warrior."
    • Also, most planets tend to explode by the time she's done with them
    • Let's face it, in her universe she's a combination of Superman, Ironman, Batman, Wolverine and Green Lantern. No wonder most people don't even think she's real anymore. Most of the Federation marines think she's just a myth or propaganda, and the Space Pirates treat Aran as their primary enemy all on her lonesome.
  • Super Strength / Super Toughness: When someone can swan-dive and free-fall off a sheer cliff on Zebes, plummet about fifty metres, unarmoured, while performing several impossible, gravity-defying feats and come to a halt with a palmed three point landing that leaves a crater then do a happy dance after this; you definitely qualify for these. For added awesome, when Samus recalls this memory in the manga; she looks to be about five.
    • And we must reiterate that, as it said above, this is on a planet with 950 times the Earth's gravity.
  • Survivor Guilt: Notice how she hits all the 'psychologically damaged' tropes?
  • Taught by Experience: She's not the greatest warrior in the universe by dint of her technology alone. The woman has had enough time lived on the battlefield to learn some mad skills.
  • That Makes Me Feel Angry: Samus in Other M does this more than a few times.
  • Tomboyish Ponytail: Sometimes seen with a ponytail when out of armor, especially in later appearances; for obvious practical reasons, she almost always wears this hairstyle under her helmet. It definitely helps reinforce her no-nonsense Action Girl nature even when she doesn't have her Power Suit on.
  • Transhuman: As of Fusion, parts of Samus' suit are fused to her nervous system, and she's part Metroid and Chozo. Despite that, she still resembles a human.
  • Wall Crawl: The Spider Ball. It is limited to magnetic surfaces in Prime, but since Samus can combine it with the Boost Ball to force herself away from one place and stick to another, it was necessary.
  • Walk, Don't Swim: How Samus handles water; becomes less of a problem with the gravity suit or gravity boost.
  • Walking Armory: When fully equipped, Aran totes more firepower than all of our world military's combined.
  • Wall Jump: Generally becomes redundant when she gets the space jump and screw attack, except for Prime 2 and 3, where the Space Jump and Screw Attack are used in tandem for wall jumping.
  • Warrior Poet: Introspective, calculating and arguably spiritual. That one silent scene of Samus surveying the burning, destroyed Chozo Temple at the end of Prime before closing her eyes with some curious, subdued emotion; cements her forever as one of these.
  • Weapon Across the Shoulder: When at rest, or to show confidence. Sam likes to rest her cannon back over one of those big spherical shoulders of hers.
  • World's Best Warrior: Highly regarded as being so, very few can stand against her and hope to live.
  • You Killed My Mother: And my foster father. And my adoptive alien race.
    • Or at least drove the latter into hiding beyond the corporeal world.
  • You Don't Look Like You: Samus's appearance in the post-game screens from Fusion looks radically different than the appearance established in Zero Mission and the Prime series, with much lighter (and wilder) blond hair, and an almost completely different build.
  • Younger Than They Look: According to the first official tie-in manga, Samus is only supposed to be 17 during the events of the first game. But there is an indeterminate Time Skip in between both volumes and the true Zero Mission, so a lot of fans call foul. Also, thanks to her Chozo blood, her age is practically impossible to determine.

The Metroids

"Metroids! This species of energy draining, unicellular aliens can be frozen, then shattered with a blast from one of my missiles, but when they are in their normal, pulsating state, they can absorb my attack. They're treacherous!"
Samus Aran

The series' eponymous bio-form, engineered by the Chozo for the sole purpose of combating the most dangerous parasitic organism in the universe. The X. As an energy leeching predator, they hatch from eggs laid by a Queen and evolve through a complicated metamorphosis into beasts capable of untold destruction; and are therefore an object of power to those who would harness their incredible abilities for war and profit. Or else revolutionize energy usage and consumption till the end of time. As of Fusion, there is only one Metroid left to the entire universe — Samus Aran.

  • Achilles' Heel: They're really weak to ice attacks, but the SR388 and Tallon IV strands outgrow this weakness eventually, trading it for others. The Super Metroid was also ice beam proof but Mother Brain managed to kill it, and that was after she lost the hyper beam.
  • Antagonist Title: Though unusually, not the main antagonists.
  • Asteroids Monster: Fission Metroids split into two Metroids when killed, each of which is only vulnerable to a specific beam weapon.
  • Attack Animal: For the Chozo. The space pirates and Ing, not so much.
  • Batman Can Breathe in Space: Phazon Metroids, which to be fair, may be because of their ability to leave local spacetime, but Miniroids do it too without that benefit.
  • Bizarre Alien Biology: They are flying jellyfish with mouths like leeches and weakness to cold and/or missiles.
  • Boss In Mooks Clothing: First two games, of the wolf pack variety.
  • Combat Tentacles: Hunter Metroids and Metroid Hatchers.
  • Depending on the Writer: The Omega Metroid and Queen Metroids of Fusion and Other M are nothing like their original counterparts from Metroid II, beyond basic appearance. This can be explained by Fusion and Other M having a different director than Metroid II.
  • Endangered Species: After Metroid 2, which is after Zero Mission and the Prime Trilogy.
  • Everything's Better with Dinosaurs: The Zeta, Omega, and Queen Metroids are basically alien dinosaurs.
  • Face Hugger: Well, mostly a Head Hugger.
  • Gone Horribly Wrong
    • They were created by the Chozo to counteract the X Parasites on SR-388. They did that — and proceeded to devour everything else as well.
    • The infant Tallon Metroid, a state that exits the egg less developed than even a larval Metroid. The Space Pirates created this state to be more manageable Metroids, with the idea they would serve as portable batteries, unfortunately Infant Tallon Metroids are mindlessly aggressive, flinging themselves with reckless abandon at all living things and can mature beyond the larval stage within seconds if they make contact with a large enough concentration of phazon (a puddle is enough).
  • Ground Pound: How Hopper Metroids attack after entering hyper mode.
  • Homing Projectile: The Queen Metroid shoots them in The Return Of Samus.
  • I Believe I Can Fly: Unless explicitly told otherwise, never assume any of them are ground bound, even if they look like it or have spent a large amount of time not in the air.
  • Insectoid Aliens: Alpha and Gamma Metroids fall into this category.
  • Intangible Man: Phazon Metroids hatched by the Metroid Hatcher that can only be killed with Hypermode.
  • Joker Immunity: They are almost as bad as the Daleks in terms of going extinct and coming back - though the Daleks don't have the on-screen justification of total idiots trying to clone them.
  • Kill It with Ice: Though at first it was just "freeze them before a shower of missiles" - and even then, in the first game they thaw out faster than any other freezable thing in the game. Later games makes them weak to cold (although in Metroid II, only infants and larva take such damage).
  • Ledge Bats: Fission Metroids in the Impact Crater in Prime. They obscure your visor when they latch on, making jumps even harder, the morph ball tends to roll off slope and they can lift the morph ball as well as the bouncing bomb explosions to detach them cause.
  • Life Energy: What they prefer to eat. They can drain all types of energy but they'll get sick if they only eat electricity, for example. The Ing used them for their ability to feed directly off Phazon and not die but had to be careful since Metroids still preferred to eat them.
    Pirate Notes: Metroid dissection continues to produce more questions than answers. Our research teams have isolated the energy conduits that run from the invasive twin mandibles to the energy core in the creature's quadripartite nucleus, but the manner in which the Metroid actually extracts the life force from its prey remains an utter mystery. The victim does not lose blood or any other vital fluids, and yet the Metroid extracts energy; identifying this energy is our central problem. It takes no physical form, and yet without it, the victim dies.
  • Maybe Magic, Maybe Mundane: See Life Force above. The Metroids drain an unidentified energy from their prey, and what this energy is may have been lost with the Chozo forever.
  • Living Battery: Super Metroid reveals that Metroids' ability to feed on ambient energy and impossibly efficient metabolisms make them an ideal power source.
  • Mega Manning: Metroid Prime and the Super Metroid both steal and assimilate weapons used by the Space Pirates.
  • Metamorphosis Monster: Their exact lifecycle depends heavily on their environment, with the conditions of their native SR388 producing the most dramatic transformations. SR388 goes Infant-Larva-Alpha-Gamma-Zeta-Omega with some becoming Queens. Tallon IV have even weaker than normal Infant stage before Larva, which becomes Hunter or Fission. In Corruption we see Mini-Phazon-Hopping-Hatcher and possibly Prime.
  • Miracle-Gro Monster: Instead of metamorphosing, the Super Metroid just kept getting bigger, actually surpassing a queen in size, being able to swallow Samus completely without the morph ball. Metroid Prime was also small at one point in time. Then there are the rapid maturing infant tallon Metroids, the Space Pirates failed attempt at a more manageable Metroid.
  • Monster Lord: The Queen Metroids. Mother Brain sorta plays this role in lieu of a Queen (she can effectively control them in the manga but not in the games). The Metroid Prime commanded a few as well.
  • Names to Run Away From Really Fast: Metroid is revealed to be Chozo for "Ultimate Warrior".
  • Our Monsters Are Weird: The people in the story itself cannot make much sense out of them
  • Palette Swap: In the first game, red Metroids always seek out Samus, though lazily, while green Metroids are a little more likely lie in wait but charge much faster. Their absence in Zero Mission indicates Canon Discontinuity. Echoes has red variants of Tallon Metroids, however they behave no differently than green Tallon Metroids seen in Prime before it.
  • Personal Space Invader: They were worse in the first game where it took multiple bombs to dislodge them, which might result in you accidentally being blown back into their grip. It only takes one to get them off in Zero Mission.
  • Powerup Let Down: The stage between Phazon and Hatcher can't even fly.
  • Removed Achilles Heel: The Space Pirates' long-term goals for the Metroids are to tame them so they'll follow orders and only attack other races, then remove their weakness to sub-zero temperatures, giving their organization an unstoppable army. In Other M, Adam and Samus find to their horror that the Federation has been thinking along similar lines, only with the utterly-suicidal oversight of having not trained the Metroids first, essentially taking a dreaded wild animal and making it invincible.
  • Shoddy Knockoff: In-universe, the Mochtroids are this to the genuine article. Sure, they drain Samus's energy, but they can't latch onto her properly, and they are weak against pretty much any weapon, not just ice and missiles. And they don't even have the right number of nuclei.
  • Stationary Boss: The Queen Metroid; if you can't beat it, you can leave and come back with more ammo.
  • Starfish Aliens: There is not a single thing in their biology that makes any sense by our standards.
  • Summon Bigger Fish: The basis of their existence.
  • Super Spit: An annoying trait of the SR388 Metroids as they develop.
  • Vampiric Draining: No puncture wounds though.

     Galactic Federation 

General. Adam Malkovich / ADAM AI

"Any objections, Lady?"
Voiced by: Dave Elvin

"You will report your full name and rank immediately... Or I will take my @#*$ing fleet and get the @#*$ out of here."

"One of them will understand. One of them must."

  • Authority Equals Asskicking: Is actually seen in battle gear in Other M.
  • Badass: If the intergalactic queen of badassery respects you, it's a given.
  • Brain Uploading: Supposedly it is fairly common for military geniuses.
  • The Captain: In Other M.
  • Exposition Fairy: In Fusion.
  • Frontline General: "General" Adam Malkovich leads a group of five men in a special-ops mission. Sometimes he is away in a command room, other times he is personally fighting with them.
  • Heroic Sacrifice: Though it is questionable if it was even necessary, something the computer in Fusion even mocks him for.
  • Identity Amnesia: Samus' AI commander in Metroid Fusion is actually a copy of the deceased Adam's mind with most of his memories suppressed (presumably to increase his loyalty to the Federation), picking up on this at some level, Samus mentally nicknames the AI 'Adam;' when she accidentally refers to him as such, it leads to him regaining his memories.
  • I Did What I Had to Do: His sacrifice of Ian Malkovich, and himself.
  • In the Back: Implied to happen to him via assassin in Other M but this was apparently a fake out scene. He later shoots Samus in the back and simply avoids the question when she wants to know why.
  • Jerk with a Heart of Jerk: Samus Aran repeatedly notes that she views Adam Malkovich as a father figure, but he does very little to ensure her well-being and remains as distant as possible. Initially, it's implied that there's a reason for this, but the story does not establish one when his character is discussed. Even the one selfless act that he does for Samus is immediately preceded by him shooting her in the back without explanation.
  • Mission Control: In Other M, not that he is particularly helpful. And Fusion, where he is much more useful.
  • More Expendable Than You: His reasoning for going to Sector 0 in Samus's place.
  • Nerves of Steel: He ordered a ship to detatch, saving the lives of his crew while sacrificing his brother in the process. He does not break down at all.
  • Nice Hat: Maybe it is a symbol of his authority, or maybe his authority lets him get away with it?
  • Reasonable Authority Figure: Only in the manga and Metroid: Fusion's ending.
  • Retcon
    • In the manga, Samus was never an army soldier under Adam's command. She was a police officer and part of an inter service rivalry with Adam since he was in the military, unlike in Other M where Samus was part of Adam's squad. Also in the manga, Adam encourages Samus to leave service and become a bounty hunter, her first mission working for him is the one he hired her for! In Other M, Samus becoming a bounty hunter was changed to be in defiance of Adam!
    • In the first Metroid game, Samus finds all of her suit upgrades. In the manga, Samus gets the bomb and missile upgrades from Adam. Zero Mission retcons it back, Samus finds the bomb and missiles herself again, along with all of her other power ups.
  • Something Only They Would Say: "Any objections, Lady?"
  • Unwitting Instigator of Doom: In Other M, he is indirectly responsible for the entire plot. The report he wrote on Metroids arguing against trying to weaponize them was so thorough that a few of the higher-ups were able to use the information in it to start a Metroid weaponization project.
  • What the Hell, Hero?: Adam gets called out by Samus for shooting her in the back and then letting her linger long enough to almost become food for a possibly invulnerable Metroid. He has no explanation for why he did what he did and just changes the subject.

"Remember me?"

Fleet Admiral. Castor Dane

"Damn! They're targeting the planetary defense system!"
Voiced by: Timothy Patrick Miller

"Godspeed, Samus."

  • All There in the Manual: Just look at the concept art portrait. Cybernetics, techno peg-leg and a solid-eye before it was cool, hell, even a freakin' laser cutlass. Dane gets relegated to ordering troops around instead. Not that this diminishes his awesomeness; enhances it really. This is what his voice actor thought of the character.
    "As I let my imagination work its magic, very quickly a vision came to me of an updated Viking Warrior Chieftain. He emerges, sailing the raging seas of space and he has dangerous and terrible tasks to struggle with. He makes decisions that cost him the life of friends and comrades in arms. He feels each loss deeply as he fights on against overwhelming odds. He rejoices in each victory. And always he is in command. Foes come at him from every side yet still he has trusted allies and some brilliant young heroes to deploy."
  • Authority Equals Ass Kicking: An armchair warrior, but no-one in their right mind would bet against him.
  • Bad Ass: That silent nod he gives Aran at the beginning of the game just reeks of this and being the sole leader of an entire fleet of starships doesn't hurt his awesome cred either.
  • Bad Ass In Charge: The man in complete command of the space forces during the Corruption Crisis and the Horus Rebellions. Where was he in Other M when you needed him?
  • Bowdlerisation: His Precision F-Strike of "Damn!" was replaced with a "No!" in the Metroid Prime Trilogy.
  • Comically Serious: Doesn't take kindly to irreverent humour directed at an old foe.
    "Aurora unit 242 has now been in usage for eighteen years. It was constructed at the same time as the G.F.S Olympus. As the AE of the flagship of the 7th flotilla, 242 can present a considerable career. With his male persona, 242 has a collegial relationship to much of the crew of the Olympus. In the jargon of former crew members, 242 is often called 'Other Brain' — something that Admiral Dane frowns upon."
  • Cool Ship: The G.F.S. Olympus.
  • Expy: The Colonel at the end of Other M somewhat resembles him. And by somewhat, he is short, old, got a pot belly and wears a beret. While Dane is in his prime, garbed in a ballistic armoured uniform and a hat so awesome that the best way to describe it is a cross between an armour-plated ushanka and a leather embossed tricorn. Also, that Colonel is a unrepentant, corrupt, douche-bag while Dane is a paragon of virtue in comparison.
  • Face Nod Action: Reserved for Samus alone, when the briefing concludes and the other hunters rush out. These two comrades-in-arms have worked together before.
  • Improvised Umbrella: Admiral Dane uses his personal flagship as one in the Space Pirate Home-world, where the rain is lethally acidic.
  • Military Salute: To Miss Aran, when she's revealed to have survived the Phazon War. And by God does she deserve it.
  • Mission Control: Sometimes.
  • Nice Hat: Heck, the hat itself is a Memetic Badass in its own right.
  • Not So Different: To our heroine; probably why they mesh so well.
    "He is stern and aggressive, and has a strong dislike for the Space Pirates. Rumor has it they orphaned him at an early age, an act he still seeks to avenge."
    Samus Aran
  • The Stoic: As befitting a man of action and command. The only point where his facade falls away for a moment is when worrying for the life of his good friend and finest free-lance soldier.
  • You Killed My Family: It is whispered about among his crew.

Universal Holo-net

"Wow! You're Samus Aran? It's an honour to meet you!"

"Know that we did our duty and fought well."

  • Call Forward: Their Stiletto-Class and gunship Samus designs using their technology resemble the ship they later give to Samus in Fusion.
  • Chest Insignia: Most troopers in Prime 3 carry the federation symbol moulded in metal.
  • Cool Guns: The federation marines have detachable arm mounted guns for both their kinetic and other energy weapons. The army soldiers have more conventional assault rifles.
  • Drop Ship: Aries-class transport vessels.
  • Escort Mission: You have to keep four of them alive during the final mission of "Prime 3." Lose too many, and it's game over.
  • The Engineer: Fleet mechanics are highly sought after and often overpaid according to the scan visor.
  • Freeze Ray: The secondary weapon of their army soldiers in Other M.
  • Glass Cannon: The Demolition Trooper armor has explosives built in it and they are used primarily for busting down barriers. Their armor isn't as good at handling direct attacks as a marine's and they lack P.E.D.s, so they don't last long in straight up fire-fights. Thankfully they know their role and mostly hang back so Samus does not have too hard a time protecting them in an Escort Mission.
  • Invisible Aliens: Not so much in the entire series, but in the Galactic Federation specifically. The manual from the first game implied that the Federation was made up predominately by aliens, but we only see humans in every game until Prime 3 and even the small percentage of the regular armed forces that are not human are presumably man made. This is most evident when MB in Other M announces her intentions to strike the Federation capital in order to punish "the humans" with no mention of any other species.
  • Kinetic Weapons Are Just Better: Seems to be their philosophy, but it proves not to be the case when they touch down on Aether. They seem to be using energy weapons in Prime 3, but are back to kinetics by Other M.
    • Fridge Brilliance: They were using energy weapons in Prime 3 that were better than their kinetic weapons, but they were based on Phazon, which Samus obliterated when she killed Dark Samus in Metroid Prime 3. They had to go back to using older technology, whether it was better or not.
  • Mauve Shirt: The GF troopers in Corruption; since they're already dead by the time you get there in Echoes, they don't promote from the Red Shirt Army.
  • Red Shirt: Fleet Troopers have no protection from attack, besides the fact they work on war ships. If something gets inside, they are kind of helpless without other soldiers or turrets to protect them. They are often ignored, but really are the backbone of the navy.
  • Religious and Mythological Theme Naming: Their individually named space craft mostly follow this, with names from Greek, Norse, and Egyptian mythology showing up as well as Epic Of Gilgamesh. There is also a task force named Heracles in Echoes and mention of a Horus Rebellion in Corruption. Because the Space Pirates frequently steal from them, much of their junk also follows this motif.
  • Space Fighter: Stiletto-Class ships and presumably other hunter class gun ships
  • Space Marine: How the organization is divided is unclear. Besides "marines", we've been introduced to the navy and an admiral, then to the army and a former general. The army's soldiers seem to have sleeker combat armor than the marines, but it is not known if this is supposed to indicate whether they are a different type of troop or was just an artistic choice, as we've never seen the army and marines side by side in a single game.
  • Super Mode: The P.E.D. Marines had one to match the space pirate's.
  • Video Game Cruelty Punishment: The hydra class turrets that protect non combatants and come in three intensity levels. Don't shoot the fleet troopers.
  • The Worf Effect: They can't get through the Pirates in Zebes and one of their corpses is found by Kraid. Sylux smashes one in the intro to Metroid Prime: Hunters. They are torn apart by Ing-possessed Splinters and then their dead bodies are possessed as well. One of their Olympus-class ships is taken by the pirates to show off how dangerous they are with phazon. You can get points for saving them during the pirate raid at the start of Metroid Prime 3, where they will die if you don't take action.
    • Naturally, players were surprised when they later are seen fighting pretty well, even though they are supposed to be the among the best troops in the galaxy. They simply never had the chance to show it up until that point, and even then, there is a blink-and-miss-it scene where two P.E.D. Marines are killed by a Pirate Commander.
  • We Will Wear Armor in the Future: Most of those placed in personal combat anyway. It is apparently as much for using more potent weapons as it is for protection from enemies.
  • Wetware CPU: The Olympus-class ships reduce the crew requirements by using organic super computers to handle most non-combat roles, allowing them to carry more fighter craft and be armed with more weapons. Originally the Aurora Units were made for research purposes, and they are also used in business and government.

    Bounty Hunters 


"Between the two of us, this should be a breeze."
Voiced by: Christopher Sabat

"That never would have happened if I'd been there."

  • Badass: The scan visor says his threat level matches Aran's.
  • Big Damn Heroes: With only seconds to spare, Rundas saves Samus from reaching the reactor of an energy shaft after she just dueled Ridley in a free-fall battle. This was his Establishing Character Moment, and part of what made him so endearing to the fandom.
  • Bond One-Liner: Gives one after shooting down two flying transports.
  • Bounty Hunter: Believes himself to be the best in this field
  • Brainwashed and Crazy: Emphasis on the crazy. You can tell Rundas is really not himself when Samus is sent to see why contact was lost with him.
  • Deadly Upgrade: The P.E.D. makes some of his attacks almost impossible to dodge.
  • Destructible Projectiles: He can stop certain shots with his powers, but given their nature, certain shots can stop his powers.
  • Dying as Yourself: When he is beaten, he seems to look around, confused. He almost tries to speak, but is impaled by an ice spike. It is uncertain whether this was him euthanising himself, or possibly Dark Samus killing him. But it makes it even more sad.
  • Demonic Possession: If you look closely when fighting him Dark Samus's image will periodically overlap his and he has some very faint audio clips that may play and they suggest he does not like what he is doing.
  • Easter Egg: A few but one in particular, he can be seen watching Samus from afar after she leaves a downed Federation vessel on Bryyo if you look carefully. (as soon as you take any action beyond one step through the door he will take off).
  • Elemental Armor: Sometimes encases himself in it, other times uses it to provide cover. Normally Rundas is something of a fragile speedster without the P.E.D.'s hyper mode but his ice defenses are surprisingly durable. Not unbreakable but the easiest way to get rid of them is trick him into helping you with it.
  • Epic Flail: In hyper mode he has a mix between this and a hammer toss. A missile shot at him while doing this can possibly result in him dropping it on his head, which knocks him straight out of hyper mode.
  • Expy: He visually resembles Noxus and has ice powers (to Noxus's freeze gun). He fights much differently, however, and is fully on the Federation's side.
  • I Work Alone: According to Federation reports, this was his attitude before he met Samus (who he seems to bond with); it explains some of his actions on Bryyo too.
  • An Ice Person: He can generate ice and control the movement of the ice he creates.
    • Hand Blast: They have the same sound effect as the Prime ice beam.
  • Impaled with Extreme Prejudice: He kills at least one enemy this way and possibly himself.
  • Irony: When he is attempting to halt the argument, he mentions that they are the good guys, justice will prevail, and all that stuff. Guess what happens to each of the Hunters barring Samus a few weeks to a month later?
  • Justice Will Prevail: He claims this as the hunters are all arguing: "Hey, relax. We're the good guys. Justice will prevail and all that stuff... right, Samus?" Headers the trope page, as well.
  • Literally Shattered Lives: To any Pirate.
  • Little "No": When his personal armor starts to break. So little you might not even recognize it.
  • Mega Manning: Samus gets Ice Missiles after slaying him.
  • Morph Weapon: He can create a variety of shapes to hit things with.
  • Not Quite Flight: Like old school Iceman, but better at it, as he generally reabsorbs his generated ice rather than leaving behind long slides of it and can travel much faster.
  • Painfully Slow Projectile: He shoots out a whole bunch to track a target and distract it while he zips off elsewhere; his serious shots are much faster.
  • She's Mine: kills his own men so he can battle Samus by him self.
  • Space Fighter: His "Phrygisian-class gunship".
  • Super Mode: After getting the P.E.D. suit and icon helmet.
  • Trophy Room: Is rumored to keep trophies from all his successful hunts.
  • The Voiceless: He dosen't speak at all before and after the boss fight.
  • You Owe Me: Guess when he says it.


"That seems... inefficient."
Voiced by: Edwin Neal

"Don't you feel the power? Soon, everything will be corrupted. Including you!"

  • Arm Cannons Akimbo: Two in his armor in addition to a Chest Blaster. He simply has a wrist launcher when not armored up.
    • Beam Spam: When desperate, he uses his smart bombs, missile salvos and plasma beams all at once
  • The Big Guy: With his suit; outside of it, Rundas is larger than him.
  • Blade Below the Shoulder: Power armor has two.
  • Bounty Hunter: Though is just as likely to be called for tech support
  • Brainwashed and Crazy: He was sent to save the Elysians from this fate but succumbed to it as well.
  • Calling Your Attacks: Before trying to decapitate Aran with a plasma lance.
    "This turn of events is insignificant. I'll show you what I mean. Observe!"
  • Car Fu: He hoists over his head then throws Samus' gunship at her.
  • Cool Ship: His suit is his ship.
  • Cyborg: Overwhelmingly mechanical
    • Cybernetics Eat Your Soul: Subverted in that he is a really nice person, but played straight with his murder frenzy in his battle suit.
  • Dangerouly Genre Savvy: He knows all too well about the Aurora Unit, and the only weapon to fix the damaged circuits is his own.
  • Deadly Upgrade: Emphasis on deadly; he seems to benefit the least from the P.E.D. Suit.
  • Deflector Shields: He uses them offensively too.
  • Glass Cannon: Without his suit. He is not particularly tough or fast but can still do a lot of damage.
    • Stone Wall: With the suit, which is very durable compared to most suits in these games, very fast and heavily armed. It falls into this trope in that it doubles as Ghor's gunship and falls behind a few of them in maneuverability and firepower.
  • Good Counterpart: Ghor is a Federation fighter who, after being rebuilt, resembles a Space Pirate (at least the ones in Prime 3). Compare to Weavel, a Space Pirate, who after being rebuilt ironically resembles a Federation soldier.
  • Grappling-Hook Gun: Strictly offensive; he doesn't need to building-swing since his suit flies.
  • Ground-Shattering Landing: Invoked in his flying heavy suit.
  • Macross Missile Massacre: From his armour suit's shoulders
  • Malevolent Mugshot: His level of malevolence is questionable, but his face was temporarily all over Sky Town.
  • Mega Manning: Samus gets a plasma beam for defeating him.
  • Nice Guy: When not in his suit.
  • Pet the Dog: His scans say that he occasionally works for free or even gives his bounty money to whoever has been harassed by his bounty targets.
  • Plasma Cannon: What his main weapon is called. Ghor actually has four. One on his person and three situated in his larger armour.
  • Shoulder Cannon: two in large armor.
  • Shout-Out: His backstory, with him having to replace his body with a cybernetic one that alters his personality, seems inspired by General Grievous, except that Ghor isn't a villain. Not initially, at least.
  • The Smart Guy: Without his suit. Despite bounty hunting being his preferred profession, he's often asked to crack or control computer systems.
  • Spin Attack: Both with his "attack claws" and sweeping around with his chest blaster.
  • Super Mode: After getting two P.E.D. icons, the second one might be for his larger armour.
  • Unskilled, but Strong: He logically assesses his situation and strikes with state of the art weaponry, but is still lacking in pure combat skill according to Federation reports on him.
  • We Can Rebuild Him: 94 percent of his body got blasted to bits in combat.


"You know, you should never trust strangers, Sammy. This is gonna' be fun!"
Voiced by: Claire Hamilton

"Space Pirate grey is definitely not my style."

  • Bounty Hunter: Aspires to be the best
  • Brainwashed and Crazy: Which leads her to try and take Samus's helmet as a grisly trophy.
  • Deadly Upgrade: The P.E.D. greatly enhances her amounts of Shapeshifter Baggage and stealth.
  • Elemental Punch: Strikes the ground when she wants space.
  • Energy Beings: It seems the reason Gandrayda is able to shapeshift is because her natural form isn't really physical to begin with.
  • Finger Snap Lighter: Sparks to electronics rather than flames to a lighter, being the future and all. She is only shown doing this after getting the P.E.D. though and even shows a distaste toward mechanical systems before getting it.
  • Get Back Here Boss: The main reason that makes fighting her so frustrating is that she spends 95% of her time jumping around, stopping only to change shapes or when she has managed to latch on to you.
  • Hive Mind: She is able to take the form of several swarm bots at once thanks to the P.E.D., and this is likely how she controls them all.
  • Homing Projectile: Air based blades and a ground based spark.
  • The Infiltration: Is more interested in hunting bounties, but gets these kind of missions because of her abilities.
  • Ms. Fanservice:
  • Invisibility: She has a personal cloaking field.
  • Laughing Mad: Just prior to fighting Samus, after she nearly shot Samus while her back was turned. And a more insane laughter toward the end of her Shape Shifter Swan Song, too.
  • Life Drain
  • Man Child: According to scans, her psyche has "a high degree of youthfulness."
  • Mega Manning: :Samus gets the Grapple Voltage after putting her down.
  • Parts Unknown: She is compared to Jovian creatures from where the Federation manufactures its steel but seems to surpass them in ability and little to nothing is known about where she really comes from or how her powers work.
  • Purple Skinned Space Babe: Or pink, purple. Whichever you prefer.
  • The Rival: She really wanted to prove herself a better bounty hunter than Samus, who in turn didn't even know who Gandrayda was until Metroid Prime 3.
  • Secret A.I. Moves: When copying Samus, she can uses some abilities much better than the player and some the player never has access to.
  • Shape Shifter Swan Song: Including both Rundas and Ghor, and most hauntingly, Samus herself.
  • Shock and Awe: It is her tell.
  • Statuesque Stunner: Her default form is taller than Samus, who is 6'3 in imperial measurements. Combine that with Gandrayda's psychological evaluation and she might not have been fully grown even!
  • Super Mode: When she receives a P.E.D. vest.
  • Voluntary Shapeshifting: She can fake phazon corruption and even turn into things larger than herself. Conservation of mass what? The other characters in the game don't understand it either.


"A skilled marksman and bounty hunter experienced in espionage skills such as scouting and tracking. While much of their background remains a mystery, including age, race or even gender. It is clear that this individual nurses a particular loathing for the Galactic Federation and her subsidiaries. Sylux uses the Shock Coil, a banned state-secret Federation-made pulse cannon that continually drains energy from enemies and refills the shooter's own. Highly classified intelligence notes that research into high-density neutrino stream manipulation similar in fact to Metroid predation led to its construction. Known for successfully shadowing the top ranked Hunter in the cosmos. Samus Aran."
Guild Data

  • Ambiguous Gender: Sylux is never referred to by gender-specific pronouns, leading to the common fan theory that Sylux is female.
  • The Blank: Like Weavel, Sylux's armor gives no indication of any sort of face. Possession of said face probably won't be known until fans get a peek under that suit.
  • Bounty Hunter: A notorious one specifically opposed to the Federation and Samus Aran by extension since they frequently hire her.
  • Color-Coded for Your Convenience: The hunter, the shock coil, and the doors it opens are all blue.
  • Cool Ship: The Delano 7.
  • Death from Above: In the intro cutscene, delivered to an unsuspecting Federation trooper.
  • The End... Or Is It?: The apparent appearance of the Delano 7 at the end of Prime 3 may count.
  • Lightning Gun: The Shock Coil: its stream jumps to the nearest target, so little aiming is required, but it is sort of short ranged. Sylux can recover health when using it.
    • Irony: Sylux has a reputation for being a sharp shot despite primarily using weapon that requires very little aiming.
  • Roar Before Beating: In the intro, though Sylux had already beaten someone, presumably the fighting wasn't over.
  • Rocket Jump: So far the only example to rival, possibly even surpass Samus, taking this trope to Not Quite Flight levels. The jumps you can make are impressive, and in low gravity, you really can fly in Sylux's alternate form, the Lockjaw.
  • Sequel Hook: Again, the possible Delano 7 appearance, which fits in line with the Sequel Hooks from the first two games.
  • Sequential Boss: Your first fight with Sylux which culminates with the Delano 7 being called on you.
  • Trap Master: Sylux's altform uses bombs like Samus's Morph Ball, but rather than detonating after a few seconds, they connect in pairs to form tripwires which wrap around any non Sylux figure large enough to set them off and then explode. Laying three causes them simultaneously detonate, so they are known as tri bombs.
  • Tron Lines: Both on Sylux's armor and ship.
  • Voluntary Shapeshifting: The lockjaw compresses Sylux into a smaller form which hovers above the ground, moving at great speeds but having inertial issues.


"Formerly a loyal soldier of the Space Pirates and a trooper in a special-forces unit. Weavel was severely wounded and left for dead in a pitched fight with Veteran Hunter, Samus Aran. Some suspect perhaps even on the surface of Zebes during the famed Emergency Order M510. What has now come to be known as the 'Zero Mission'. Like the other hunters, he also seeks the Ultimate Power. His weapon of choice is the rapid-fire, heavy-duty Battle hammer; a nuclear repeater. Weavel can transform into the Half-turret, where his upper and lower body split and can attack separately. Proof of the severity of his injuries, it's safe to say he bears a simmering grudge against the Raging Devil."
Guild Data

  • Ascended Extra: He would have to be one of the pirates from the Zero Mission remake for his story to make any sense with the information we know. It is possible another game could occur during the time period though, as Metroid has been skipping around since Prime.
  • The Blank: Possibly. It's not entirely clear if that yellow section of his head where his face would be is a cybernetic face or just a visor. A fan theory is that he's a Ki-Hunter, which would make that yellow part his actual face if true.
  • Bounty Hunter: What he has been reduced to. It is unknown whether he retains any loyalty to the space pirates or has simply decided to work for his own benefit.
  • Color Motif: Weavel's suit has a mild green tint and the battle hammer is green.
  • Cool Ship: Though it's not as prominent as the Delano 7, it can be seen in the intro movie, where Weavel is using it to evade the GF Police. It's also briefly seen on the Oubliette.
  • Cyborg: The only part of his body that Samus didn't shred beyond repair was his brain and spinal cord.
  • Detachment Combat: He can be significantly weakened if one of his halves is disabled though he can also pick up power ups in this state and end up with a larger health bar than any other hunter can have until he recombines.
  • Parts Unknown: Said in the game's intro.
  • Mark of Shame: His new cybernetic body is a constant reminder of Weavel being completely wasted by Samus. In fact, it's the reason why he is no longer a high-ranking Pirate.
  • Remember the New Guy: Apparently, Weavel lost his body while fighting Samus on Zebes in the first game. In Brinstar. Which never contained any Pirates at this point in the chronology, neither in the first game nor in Zero Mission.
  • Space Pirate: Though technically, he is no longer officially affiliated with them.
  • Swiss Army Appendage: He has the trademark Space Pirate scythe, which he only uses in his alt-form during game play. This one is actually a rather mild example as far as Pirates go, because while Weavel's scythe is merely attached to his arm, Pirates tend to replace their arms with such scythes.
  • Splash Damage: The battle hammer has a bigger blast radius when used by him.
  • The Turret Master: He can split his body in half and the lower half will become a turret.
  • We Can Rebuild Him: He was originally just a high-ranked space pirate (probably a Commando or Trooper) until he was completely blown to smithereens by Samus and rebuilt as a cyborg.


"Subject is a member of the Vhozon, a highly esteemed monastic race on the Outer Rim of the galaxy. Noxus' sole reason for trying his hand at bounty hunting is to stop crime and protect the Universe from losing the balance between good and evil. As did many of the other bounty hunters, Noxus received word of an opportunity to receive an extremely powerful weapon from the Alimbic Cluster, which he frantically goes to search for in hopes he can use it to bring peace to the Galaxy, or at the very least stop it from falling into unworthy hands. His personal firearm is the Judicator. A ricocheting blunderbuss powered by cold-fusion synthesis. It fires supercooled plasma at temperatures approaching absolute zero."
Guild Data

  • Bounty Hunter: Though most of the industrial world considers bounty hunting to be a criminal activity, Noxus became a bounty hunter specifically to fight criminals and other forms of "evil". Guess times have really changed in the space age.
  • Color-Coded for Your Convenience: From the hunter himself, to his ice weapon, to the doors that can be opened once Samus gets his weapon, his main color is purple.
  • Everything's Better with Spinning: His alt. form has him curl up and spin like a top.
  • Extra Eyes: He has four eyes.
  • Hero Antagonist: The only reason he even ends up fighting against Samus is because his goal is to keep the Ultimate Power out of the wrong hands. Presumably, Samus and the Galactic Federation would fall under "the wrong hands."
  • I Have the High Ground: In the game's intro.
  • An Ice Person: By way of his Weapon of Choice, the Judicator. He can release a vapor wall that freezes enemies in place when he charges a shot.
  • Knight Errant: He left his home world to go on a crusade against all evil in the universe.
  • Natural Weapon: The Vhoscythe.
  • Spin Attack: In his alternate form.


"A science project gone awry, an experiment to create a so-called super-soldier that was practically invincible. However, Kanden's mind was still no more than a mere Enoema's, and therefore his brain could not withstand the complicated neural combat encoding sequences. This completely transformed his mind, leaving him as a ferocious, unbelievably powerful and dangerously unpredictable monster. Kanden escaped the research lab, killing the scientists that created him, and destroyed their laboratory. Kanden then took great advantage of his strength, durability, and near-immortality by trying his hand at becoming a bounty hunter. Built with programming to hunt, fight and destroy, he could be the ultimate template of that same project. Fittingly, he boasts an equally terrifying and experimental tool of his trade. the Volt Driver draws energy from the planetary electromagnetic field the wielder is situated on and converts it into five-figure terawatt bursts of High amplitude ball lightning."
Guild Data

  • Beware My Stinger Tail: His alternate form shoots explosive stingers.
  • Bounty Hunter: Though, he does it less for the "bounty" part and more for the "hunter" part.
  • The Brute: He is one of if not the largest bounty hunters if it is not Spire and has one of the least sympathetic goals, so this is his role when they eventually team up.
  • Color-Coded for Your Convenience: Though the hunter himself is green, his weapon, the Volt Driver, is yellow, as are the doors that Samus can open once she gets this weapon.
  • Extra Eyes: He has four eyes in biped form and lots of markings that superficially look like eyes. The stinglarva appears to have seven eyes in official art, or rather six with one of those markings as a big eye spot.
  • For the Evulz: The main reason he became a bounty hunter, and the reason why he is searching for the Ultimate Power of the Alimbics, is because it gives him a chance to fulfill his killing potential.
  • Gone Horribly Wrong: He was originally a lab experiment to create a super-soldier, but he escaped. He wouldn't have the mental stability to serve as a soldier anyway.
  • Humanoid Abomination: This is what you get when you combine an unnaturally augmented scientific experiment with a mind that is just barely holding onto its sanity.
  • Interface Screw: His special weapon, the Volt Driver, can distort a target's vision when they are hit by charged shots. It homes in on the target when he fully charges it.
  • Nightmare Face: Let's just say that his face is rather unnerving.
  • Psycho Prototype: And because of it, we may never get to see the finished product
    • Psycho Electro: His weapon of choice is the volt driver, which is sort of like a combination between Samus's power beam and electro lob. Charging a shot causes them to home in on targets when he uses it.
  • Rocket Jump: How his Stinglarva form jumps, though not as good at it as the Morph Ball or Lockjaw.
  • Stuff Blowing Up: In his intro, a building blows up behind him; possibly the facility he came from, but who knows.
  • Super Soldier: The reason the scientists made him in the first place, though their final product would not be no good for it. They at least succeeded at making a killer.
  • Tron Lines: Well, more like Tron Circles.
  • Voluntary Shapeshifting: The stinglarva he compresses into makes use of biological material from several predatory insectoid aliens


"Spire is the last of his kind, a race known as the Diamonts. They are extremely strong, composed of silicon-based organic rock and hail from the planet Mondreus. Not much is known about him except that he wearily searches for the fate and location of the rest of his people, if any are to be found. When Spire hears of a source of Ultimate Power in the Alimbic System, he is drawn by the possibility of discovering clues to the whereabouts of his lost race. on hunts, he wields an ancestral mortar called the Magmaul, powered by a hyper-static hydrogen core, it belches cohesive projectiles of ultra-compressed magma.""
Guild Data

  • The Big Guy: He has a sympathetic goal, making him one of the more heroic bounty hunters when they eventually team up.
  • Be the Ball: When he becomes the Dialanche
  • Bounty Hunter: To support his search for his kind or answers as to what happened to them
  • Collision Damage: The Dialanche, as seen in the intro. It has to be right when he transforms or at full speed, though, so you're better off using the attack button instead.
  • Color Motif: From the hunter himself, to his magma weapon, to the doors that can be opened once Samus gets his weapon, his main color is orange.
  • Creator In-Joke: Retro Studios based his design off a creature from one of their canceled projects. Nintendo Software Technologies wrote his back story with that in mind.
  • Last of His Kind: Indeed, the reason why he is seeking the Ultimate Power in the Alimbic system is because it may provide him with an opportunity to find out what happened to the rest of his species.
  • Magma Man: In fact, according to his scans, his body contains "molten ferrous compounds normally found only in a planet's core." His weapon of choice shoots lava grenades, and charged shots light things on fire, doing more damage when he uses it. He can also move through lava without taking damage (though the lava from his own weapon is too hot for even him to withstand, or maybe it's just competitive balance?)
  • Rolling Attack: Seen the Hunters intro movie
  • Shout-Out: Spire seems very similar to Gorons, in that both are rock-based creatures that roll up into boulder-like balls.
  • Silicon-Based Life: Which probably explains why he is at home in molten environments, one theory is that such creatures would have to live in incredibly hot environments or else move extremely slow.
  • Wall Crawl: his Alternate form can do this.


"A feared bounty hunter and a subject of the Kriken Empire, Trace is a remorseless individual. At a certain age, Kriken youths are exiled by their clans and sent to distant planets as a rite of passage to find suitable territory for their empire to invade. Trace is currently taking his rite of passage and has become a bounty hunter to travel the Galaxy in search of technology and land that may increase his standing. Trace sees the so-called Ultimate Power as his chance; if he succeeds in obtaining it, then he will be considered a hero among his people. With a brittle exoskeleton that cannot compete with the durability of his rivals. Trace uses his tactical preference for sniping to compensate for this vulnerability. And with his weapon of choice being an Imperialist sniper rifle, (a long-range quantum cascade laser with a precision scope) He more than lives up to his bloody reputation."
Guild Data

  • Always Chaotic Evil: His race, the Kriken, thrives off of being this, almost to the extent of putting the Space Pirates to shame.
  • Bio-Augmentation: The Triskelion is the result of this.
  • Bounty Hunter: He entered this field of work in hopes he would find suitable worlds for his kin to conquer, which makes you wonder how he ever gets work. That or technology that would revolutionize his empire.
  • Cold Sniper: His weapon, the Imperialist, is a red laser that actually has a sniping scope of sorts. As such, it has the longest range of any of the hunters' weapons.
  • Color-Coded for Your Convenience: From the hunter himself, to his sniper weapon, to the doors that can be opened once Samus gets his weapon, his main color is red.
  • Glass Cannon: Samus, or at least the scan visor, suspect him of being one of these, relying on stealth rather than toughness for defense.
  • Glory Seeker: To advance in Kriken society, he has to be.
  • Human Ladder: He stands atop a mount of what can be presumed to be other Kriken in the intro.
  • Invisibility: What happens when he fires his weapon while standing still. His alternate form has invisibility when standing still as well.
  • Raymanian Limbs: Well, his head has no connection to his body.
  • Rite of Passage: His involvement in the story has him seeking the Octoliths as part of this. He fails, of course, but then again, the "Ultimate Power" he was looking for didn't really exist in the first place.
  • Secret A.I. Moves: In the strictly one-player mode, he can rapid-fire the Imperialist. We repeat — he is rapid-firing a sniper rifle. Only during his very first appearance, though, and only if you provoke him into doing it. (you're "supposed" to fight Noxus and hide away as Trace tries to snipe you but if you're skilled and stubborn enough, you can defeat Trace first. He flees on his own after you beat Noxus, meaning beating Trace is pure bragging rights reward)
  • Shout-Out: Kriken society is a pastiche of the Irken's.
  • Voluntary Shapeshifting: He can become a three legged triskelion, which does not run especially fast but can move very quickly by jumping/lunging, giving him a different problem with inertia to Sylux's.

    Space Pirates 


"The reconstruction of geoform 187, code-named Ridley, was recently completed. After his defeat on Zebes, Command ordered a number of meta-genetic improvements for him. Though aggressive, we were able to implement these changes in a cycle. The metamorphosis was painful, but quite successful in the end. Early tests indicate a drastic increase in strength, mobility, and offensive capability. Cybernetic modules and armor plating have been added as well. We believe our creation, now called Meta Ridley, will become the mainstay of our security force, a job he will certainly relish."
Project Orpheon
"Time for you — TO DISAPPEAR!!!"

Attack Dog of High Command, General of the Mother Brain. Lord Ridley is the unabashed, sociopathic, recurring arch-nemesis to the main protagonist; Samus Aran. Responsible for the razing, pillaging and mass-murder of innumerable innocent settlements in his crusade against the Galactic Federation and the forces of order; Ridley lives for carnage and his sadism is only matched by his deceptive cunning. Of an unknown but fearsome race, the cruel Space Dragon inadvertently creates one who will ensure he harms no other.
  • Archenemy: To Samus.
  • Ascended Extra: In Metroid 1 he was just a one-note mini-boss who guarded one of the lock mechanisms to Mother Brain's hideout. Contrast that with the unending praise he's had heaped on him since then.
  • Asskicking Equals Authority: There's a reason he's so high up the Space Pirate chain of command.
  • Back from the Dead: See Joker Immunity.
  • Badass: It's heavily implied that the only person in the entire galaxy who is a threat to him is Samus. Let's see what he (chronologically) accomplishes:
    • Prior to the series, he single-handedly annihilates dozens of space colonies (including the one Samus lived in, whoops) and occupied Zebes, wiping out the remnants of the Chozo civilization. He also survives his flagship crashing down on top of him thanks to Samus' father detonating the Afloraltite on board. He claims this seared the flesh from his bones and he still managed to survive without medical aid.
    • He fights Samus one-on-one in Metroid and, while losing, manages to not only survive his injuries but escape the endgame explosion, and lives through his injuries long enough for the pirates to save his life by making him a cyborg.
    • In Prime, the newly roboticized Meta Ridley is more or less the only Space Pirate to live through the destruction of their frigate, and later survives not only a thrashing by Samus but also being blasted by the statue guardians of the Artifact Temple; falling into a canyon, then blowing up.
    • In Corruption, he lays waste to a whole Federation outpost before dragging Samus into a freefall battle. He not only survives, he takes in so much Phazon he becomes a full-blown Leviathan guardian. And, unlike other powerful beings of Phazon, he lives through Phaaze's destruction at the end of the game.
    • In Super Metroid, he attacks a science facility, steals the baby Metroid from right under Samus's nose, and fights her again. He finally dies in this game, and it takes the fifth canonical beat down by his archnemesis coupled with being caught in an exploding planet to kill him.
    • His clone in Metroid: Other M wreaks havoc in the station and slaughters scientists and even some soldiers while still an infant. The frequency of his voice is driving the other beings in the Bottle Ship into a frenzy, meaning that even when he's not around to directly make things worse, he's still making things worse. Killing the clone requires no less a being than a friggin' Queen Metroid, and this is after he's worn out in another battle with Samus. Adam Malkovich considers the clone such a threat that he chooses to make Heroic Sacrifice rather than face it, considering Samus the only person reliably able to battle Ridley.
    • Even in Fusion, the worn-out, dead, frozen husk of his clone is suitable for X parasite cloning. Yes, a clone of a clone, and he's still an endgame boss.
  • Batman Can Breathe in Space: And fly, and survive re-entry without issue. His species is known as "the Space Dragons", suggesting they have adapted to vacuum environments.
  • Beware My Stinger Tail: His tail is pointed and barbed, and is first used as a weapon in Super Metroid. It's also one of the few things that can damage Samus when she's using the Screw Attack. Omega Ridley can shoot short ranged beams out of his tail.
  • Big Bad: Of the two main plots in the first Metroid Prime, he's the Big Bad of one of them and is the cause of the entire game.
  • Big Eater: In Other M, he eats constantly as "Little Birdy" in order to hasten his metamorphosis.
  • Blood Knight: Ridley enjoys nothing more than ripping things apart.
  • Breath Weapon: What did you expect from a dragon? Ridley can spit plasma hot enough to melt through spaceship hull.
  • Brown Note: In Other M, it's revealed that the frequency of Ridley's voice drives Space Pirates and some other creatures into a murderous battle frenzy, essentially making Ridley a perfect military commander. It also may have had something to do with Samus's mental breakdown.
  • Create Your Own Villain: Inverted. He killed Samus’ mother in attempting to kill Samus, thus Ridley had succeeded in creating his greatest enemy.
  • Creepy Child: In Other M. Somehow ironic how Ridley seems to be creepier when he's a cute newborn chicken thing.
  • Dark Lord on Life Support: After his defeat on Zebes in Metroid the Space Pirates recovered his body, put him on life support in the Frigate Orpheon, and reconstructed him using cybernetic implants, turning him into Meta Ridley.
  • Deader Than Dead: Let's see, as of Fusion, his clone was reduced to ash, and then the station it was on was sent to a planet that then exploded. On the other hand, he's already been cloned once, and since Samus is an outlaw at the end of Fusion, it's not impossible that he won't be revived in some fashion, given that Ridley is the natural choice to hunt down Samus.
  • Depending on the Artist: His size, color scheme, and even appearance have all wavered throughout the series. The only thing that's been consistent since Super Metroid is that he's larger than Samus, but just how large depends on the situation. See Your Size May Vary below.
  • Disproportionate Retribution: As a child, Samus attempted to befriend Ridley, embarrassing him in front of his fellow Pirates. What does he try to do in order to save face? KILL HER.
  • The Dragon: To Mother Brain in the original/Zero Mission and Super, and to Dark Samus in Prime 3. He may have been the supreme leader of the Pirates before Mother Brain took over, and is clearly in command in Prime 1 in Mother Brain's absence.
  • The Dreaded: Let's put it this way: Adam Malkovich expressly considers Ridley to be just as much of a threat as a station full of invincible Metroids. He is probably the only thing in the universe that can scare Samus stiff (though that has been attributed to Post Traumatic Stress Disorder). That is how dangerous this guy is.
  • Early Installment Weirdness: The American art for the first Metroid game showed Ridley as a weird dragonfly thing instead of the more familiar space dragon. This might have been due to the art being based on his in-game sprite, which admittedly was rather vague on his appearance beyond "winged monster."
    • Him being the same size as Samus.
  • Even Evil Has Standards: Subverted in the manga. Ridley at first seems to avoid trying to kill Samus, but was instead lowering her guard. She's 3 years old at the time.
  • Evil Counterpart: Perhaps this is Alternate Character Interpretation, but he and Samus tend to parallel one another, with being extremely powerful and intelligent. They are also presented with the same option of killing or sparing each other as a child with opposite results. Additionally, Ridley and Samus are just as unkillable; Samus as a player character can "continue" if killed, and Ridley "continues" every time he dies.
  • Eye Beams: Mecha-Ridley after his protector is broken.
  • Genetic Memory: His clone in Other M seems to know EXACTLY who Samus is.
  • Faux Affably Evil: Not so apparent in the games but shines through in the manga, especially when he meets Samus for the first time.
  • For the Evulz: It's implied that the only reason he's with the Space Pirates is that he enjoys killing people.
  • Genius Bruiser: It's All There in the Manual. Finally somewhat shown in Other M.
  • Ground-Shattering Landing: Meta Ridley and Omega Ridley.
  • Healing Factor: He can eat organic matter in order to regenerate lost mass. He taunts Samus by saying he did this to her mother. However, this ability seems to occur a lot slower than most other examples.
    • His healing ability can be seen somewhat in Corruption, presumably sped up by Phazon enhancement. The first time you fight him, as Meta-Ridley, most of his body is plated with or replaced by metal. When you face him a month or so later as Omega Ridley, he's healed enough that he's shed off a lot of his metal parts and what isn't removed is starting to get pushed apart by regrowing flesh anyway. Certainly justifies why he goes back to being regular Ridley in Super Metroid.
  • Homing Projectile: Mecha-Ridley's missiles.
  • Improvised Armor: Omega Ridley whips some up after you tear open his original armor plates.
  • Informed Attribute: The intelligence that he exhibits in the manga, and which pretty much all supplementary material talks about, is never really touched upon in-game. Then again, we rarely see him when he's not fighting Samus, so who knows. Though it does get shown a bit by his clone in Other M.
    • Note that in the Other M example, Ridley brutally attacks the team of mercs and uses the terrain to his advantage. Then he noticed the extremely deadly Plasma Beam aimed right as his face and takes off. He doesn't just run either, he leaps and twists to make himself a harder target to hit. You know a weapon's powerful when Ridley turns tail and bolts.
    • It's also exhibited during his attack on Norion in Corruption, as he tries multiple times to attack Samus while she is in Morph Ball mode, incapable of really fighting back. After this fails, he drags her into a freefall battle; considering Samus can't fly, even if he lost the fight, she'd still fall to her death. And then Rundas shows up to save Samus, ruining all the fun.
  • Joker Immunity: Officially averted in Super Metroid, where he canonically died. The ones in Fusion and Other M are a clone that was killed by a Metroid Queen and resurrected by an X Parasite. However, considering he's Samus's greatest nemesis and one of the iconic villains of the series, it's a sure thing that Ridley or a clone of him will continue to pop up.
  • Killed Off for Real: In Super Metroid the entire planet of Zebes is blown up with his body on it. His clone is sucked dry in Other M and finally killed by the X in Fusion.
  • Lack of Empathy: He cruelly mocks Samus for her PTSD-enduced memories of her mother being killed by him, as well as that he absorbed a bit of her cells.
  • Lean and Mean: Except the Other M clone, which was bulky
  • Leitmotif: The most memorable one in the series.
  • Lightning Bruiser: Able to tear around the screen at an amazing speed given his size, as well as deal out considerable damage to Samus.
  • Might Makes Right: In the manga: "In battle, nature sides with the strong! You shall realize just how worthless your ideals and such are — AH HA HA HA HA HA!"
  • Ninja Pirate Zombie Robot: Hilariously, he is a space dragon who is the leader of the Space Pirates and often comes back from the dead, sometimes as a cyborg. If you count that he is capable of "invisibility" in Super Metroid, he is a literal Ninja Pirate Zombie Robot.
  • Our Dragons Are Different: They are anorexic and can fly in space here.
  • Power Palms: On occasion as Omega Ridley. Subverted in that you can shoot them dim.
  • Psycho for Hire: The manga and some of the Data Logs in Metroid Prime imply that his reason for being with the Space Pirates boils down to a sadistic love of killing other beings, which is his forte.
  • Razor Wings: Averted, the designers went out of their way to make sure players would not have to worry about his wings in the 2D games. He does use a couple wing attacks in Super Smash Bros Brawl, however.
  • Recurring Boss: The only enemies/bosses to appear in more games than him are the Metroids themselves.
  • Robot Me: Mecha-Ridley in Zero Mission.
  • Suddenly Voiced: His appearances in spin-off material give him the ability to speak. He never speaks in-game.
  • Taking You with Me: His first boss fight in "Prime 3," which has you on a time limit that ends with Samus crashing into Norion's core.
  • Throw Down the Bomblet: The first Meta Ridley fight sees him do this. The second sees him throw them upwards.
  • Unexplained Recovery: Metroid Prime was the first game to even make mention of his recovery and the explanation for it was not very detailed.
  • We Can Rebuild Him: Meta-Ridley and later Omega Ridley.
  • Wipe The Floor With You: In Other M he the walls of the Geothermal Power Plant if you let him grab Samus, which he previously did in his Boss cutscene from Super Smash Bros. Brawl. No Pikachu to save Samus in Other M but you can just shoot Ridley in the face to make him let go.
  • Would Hurt a Child: Almost killed Samus when she was three years old.
  • You Are Number Six: Ridley is his codename. His real identification is Geoform 187.
  • Your Size May Vary: This led to discussions about whether he wasn't a playable character in Super Smash Bros. Brawl because he was "too big."
    • A truly excellent example of this happens in Metroid Prime 3, where in the beginning he was large enough to have Samus fit into his mouth just barely as they fell down the tunnel. Later on in the Pirate Homeworld, after becoming infused with Phazon to become Omega Ridley, you would think he would be just as large as before, right? Nope! He's suddenly sized down to the point that Samus could only fit her arm cannon into his mouth. Justified, if you look at it as being a classic duel between two arch-enemies on even foot.

Mother Brain

"Did you finally realize you are nothing but a beast as well? ... No, more accurately - that you're just a bird that can't even fly."
Voiced by: Levi Stubbs (TV Iteration)

"Lying doesn't become you, nor does jealousy. Your jealousy of 'life' and 'the future!' And of Samus!!"
Gray Voice

"Defective product... Me...?!! A 'defective product'... You dare claim that I am defective...!!"

The Mechanical Life Vein of Planet Zebes, progenitor of the Aurora Unit Biological Super Computer Complex, the self-proclaimed 'Mother' of the multiplied Metroid hordes and the true leader of the Zebesian Space Pirates. Once a benevolent AI system that assisted the last of the Chozo, she devolved into rampant insanity as a result of being surpassed by their last child, leaving her legacy in the dust. Jealous and spiteful of 'lesser' life-forms. Mother betrayed her caretakers and allowed the Space Pirates to invade Zebes; upon which she seized control of their armies with powerful telepathy. A deluded Darwinist, Mother seeks nothing more and nothing less than the subjugation of every living thing.
  • Arch-Enemy: While not quite as personal as Ridley, Mother Brain is still one of the most recurring villains of the series, and earns Samus's ire in various ways, most notably killing the baby Metroid. It's somewhat more prominent in the manga, where she played a part in raising Samus, before becoming one of her adversaries, unlike in Zero Mission where Samus says she grew up on Zebes long before Mother Brain was there.
  • A.I. Is a Crapshoot: Retconned in the Prime series as an organic machine built by the Chozo, instead of the Space Pirate leader. This is in the manga too. The manga reconciles these roles (she takes the pirates over), but Other M seems to disregard both the Prime series and a bit of the manga (saying that the pirates can't function without her).
  • Archnemesis Mom: With Samus in the manga.
  • Big Bad: More often than not. Could be considered the most prominent Big Bad of the main series.
  • Brain in a Jar: And you get to break it out.
  • Cyclops: Not originally though
  • Dark Lord on Life Support: Extreme inversion: Mother Brain is a giant brain in a highly impact resistant glass casing. After breaking through the shield you still have to fire multiple missiles(regular beams do nothing) directly at her bare grey matter in order to finish her off proving that the transparent casing is clearly for protective reasons only.
    • That said, the Zebetite barriers were said to be crucial power sources that kept her alive in the first game's manual. The manga changed this to Zebetite merely being there for her protection, which in a rare case of it closing a plot hole rather than creating more, explains why Samus did not simply walk away after destroying all the Zebetite.
  • Death by Irony: Almost manages to kill Samus in Super Metroid, but is suddenly attacked by the fully-grown baby Metroid she stole, which chomps her head in retaliation. Ha!
  • Early Installment Weirdness: In the first game she had two eyes, a nose, tusks, and did not attack directly. In Super Metroid, she only had one eye and was more active. The first game's remake retconned Mother Brain to have only one eye and to actively defend herself.
  • Evil Counterpart: Like Samus, she's heavily associated with maternal themes, and in the manga was also created by the Chozo to be their ultimate creation of sorts, mirroring Samus's own upbringing as a great warrior. Yet while Samus is heroic and rebellious, Mother Brain enforces order and hierarchy.
  • Eye Beams: She is the only boss from the first game to be made more difficult in Zero Mission. She doesn't shoot them normally though, being in a jar and all.
  • Informed Ability: The psychic powers she is said to have in the manga are never made use of in the games (unless you count her eye beams and Hyper Beam, which could just as easily have mechanical sources). The events of Zero Mission are the strongest evidence against them, as the space pirates in her lair still fail to control the metroids, which can be contrasted with Metroid Prime 3, where Dark Samus does prove capable of getting Metroids to temporarily work along side other creatures against Samus. Also, Other M's suggestion that the pirates would fall apart without her is contradicted by the manga, where they were pirating before she came around, and the prior games, where they stayed together after she, Ridley and Kraid where all blown up by Samus.
  • Legacy Character: The Aurora Units in Prime 3 were derived from her and it is implied the Mother Brain seen in Super Metroid was an Aurora Unit herself. Melissa Bergman in Other M'' is an android created to replicate Moter Brain's AI.
  • One Bad Mother: Everyone just calls her Mother in the manga. This gets referenced in Other M.
  • One-Winged Angel: After Samus seemingly kills her in Super Metroid she interfaces with a massive robotic body.
  • Scare Chord: The melody for her battle music in Super Metroid consists of these.
  • Sassy Black Woman: In the non-canon Captain N: The Game Master show.
  • Spikes of Villainy: They serve no practical purpose other than looking scary.
  • Stationary Boss: Most of the time.
    • Cores and Turrets Boss: Destroy the Zebetite barriers, avoid the turret shots and rinkas. Break the glass then shoot the brain. Also, watch out for the occasional pit of lava. Zero Mission adds the additional defense of an eye lid, which will deflect your attacks while it charges her eye beams. Unfortunately for her, she has to release the charge eventually, leaving her eye vulnerable in the cool down period.
  • Sympathy for the Devil: In Other M in the form of Melissa Bergman.
  • Turned Against Their Masters: Depending on which source you are looking at, she either let the space pirates into Zebes to kill the Chozo or took over the Space Pirate when they came into Zebes then had them kill the Chozo.
  • Villainous Breakdown: A huge one in the manga. Gray Voice betrays her, knowing her intentions to rule the universe. He'd have killed her two if not for Ridley's timely arrival.
  • Well-Intentioned Extremist: In the manga, it's explained that her true goal is to bring order into the galaxy.


"Ah, Ridley's comrade. His skin is on par with an anti-optical shield. Your weapons are useless against him."
Mother Brain


Along with his co-captain, Ridley. Kraid is a gargantuan mainstay of the Space Pirate forces and one of the guardians of Tourian. Immense and corpulent, his regenerating organic projectile weapons and sheer girth make him a force to be reckoned with. Thankfully, he's not too bright.
  • Achilles' Heel: The wave beam in the first game. Stand on the block in front of him, shoot, dodge occasionally and he goes down.
  • Attack of the 50-Foot Whatever: Not in the first game though
  • Bizarre Alien Biology: A giant dinosaur with the standard claws and teeth? Pretty normal as far as video game monsters go. Three eyes? That's only slightly pushing the envelope. Spikes that shoot out of its belly that Samus can jump on? Alright, now that's not exactly normal.
  • The Brute: With Ridley and Mother Brain in the first game.
  • Co-Dragons: He's the brawn, Ridley is the brains... and a lot of the firepower as well.
  • Colossus Climb: Kraid, although you jump on improvised platforms instead of climbing.
  • Disc One Final Boss: In Nintendo Land's theme park version of Metroid.
  • Early Installment Weirdness: Kraid was actually really tiny in the original Metroid. Zero Mission retconned this out when it made him gigantic as well.
    • Also, the green on his body that is portrayed as scales in all later games is portrayed as fur in the original's American artwork.
  • Fake Ultimate Mook: There is an enemy that looks exactly like him in the first game, but dies in one hit and doesn't open the way to Tourain. "Fake Kraid" in Super Metroid was actually in the same room as Kraid in the original. This was to add dramatic effect once the player entered the next room and saw just how gigantic the real deal was.
  • Lowered Monster Difficulty: He was the most difficult boss in the first game! Ridley and Mother Brain proceeded to get harder in most of the other titles they appeared in while he became easier in both Super Metroid and the first game's remake.
  • No Sell: His skin is as tough as specialized armor and shielding. All attacks against his body simply bounce off.
  • Red Eyes, Take Warning: His eyes are usually glowing red, though he had white eyes in Super Smash Bros Melee
    • Third Eye: Shoot it to get him to open his mouth!
  • Spike Shooter: In Metroid and Super Metroid he fires spikes from his belly.
  • Tactical Suicide Boss: He would be invincible if he never opened his mouth or shot spikes out of his belly.

The Space Pirates

"The feared and mysterious Space Pirates. In truth they are... a subordinate species that naturally follows the orders of a strong master. It is just like how the worker bees follow the queen bee, their hierarchical programming is decided at the genetic level."
Mother Brain

"Science Team believes the Metroids can be trained. After several cycles of trying, I believe Science Team has vapor for brains. I've lost two assistants to the wretched little things."
Scan Lore

"Death before dishonor."

An inter-stellar cabal, comprised of numerous species that have rejected the Galactic Federation's democratic rule in favour of a life of thievery. As brigands, the Pirates steal any technology which will improve their cause and they subvert science to ensure the supposed superiority of their biological traits. Opportunists to the core, they care only for their own advancement as a race. And they will trample over anyone and everything to achieve that fact.
  • Always Lawful Evil: The Space Pirates. It's claimed any space pirates who question "The Way Things Are" are executed, sometimes on the spot. Any space pirate who expressed non-evil thoughts wouldn't have a very long life expectancy.
    • According to some scans in the Prime series and some out-of-game info, not all of them are very happy with evil being the law, and certain POWs were incredibly easy to interrogate. Other scans seem to paint them more as Lawful Stupid, with common troops not being nearly as malicious or cunning as Science Team. Of course, that's not saying much.
    • In Echoes, the Ing love Pirate hosts because their lawfulness makes them easier to control. In the manga and Other M, Pirates are depicted as easily commanded by beings with minor Psychic Powers like Ridley and Mother Brain.
  • Armored Coffins: Their boarding pods.
  • Beast of Battle: While all their attempts to use Metroids for anything useful have spectacularly failed, Pirate Kussars have managed to tame the mighty Korakk Beast. They also are able to make use of the Bombus, Preeds, and later Puffers to a limited extent.
  • Beware the Silly Ones: While the Space Pirates constantly fall victim or play second fiddle to the bigger threats in the series, it is worth noting that the majority of these threats are some degree of Eldritch Abomination. It's easy to forget that they're one of the most versatile, violent and feared alien races this side of the galaxy.
  • Butt Monkey: In Echoes, especially. "Surely, we are cursed."
  • Comedic Sociopathy: The Data logs provides a humorous side to their antics. "They were promptly shot." Followed by "They too were shot."
  • Creative Sterility: Almost all of their tech is stolen or reverse-engineered.
    • But also Subverted; while they steal a good deal of their technology, they are also extremely active in researching and improving their home-grown tech. The Hazard Shield (which is required for them to put up with the acid rain on their base world) is a good example.
  • Cult They form one around Dark Samus in Corruption.
  • Deadpan Snarker: Part of what makes many of the logs so hilarious.
  • Depending on the Artist: Space Pirates tend to look different in every game. The manga depicts them as having numerous subspecies.
  • EMP: They have grenades that produce them, which is strange since they don't work very well against their sworn enemy, Samus.
  • Eternal Engine: Their homeworld is like this, complete with a perpetual shower of acid rain.
  • Elite Mook: Omega Pirate, an early specimen of Phazon experiments.
  • Evil Knockoff: Their attempts to reverse-engineer Samus's technology.
    • According to logs taken from the original Prime, the pirates did some poking around into the Morph Ball technology, only to have their results break every bone in the test subjects bodies. Needless to say, that venture took them nowhere.
  • For Science!: Even though they think that their Science Team has vapor for brains.
  • Genre Blind: Any pirate who does not engage Aran on sight risks being tried for treason, which basically enforces Attack! Attack! Attack!
  • Ineffectual Sympathetic Villain: In Echoes only, due to being caught in a three-way.
  • In Name Only: They are frequently referred to as Zebesians, but Samus is more of a Zebesian than them, having been raised there. These guys are just brigands who set up some laboratories and hidey holes, then started raiding the ruins. Yoshio Sakamoto has compared them to how most "Americans" are actually descended from Europeans.
  • Instant Awesome, Just Add Ninja: The two space pirates that guard Ridley's lair in Super Metroid have been called "Ninja Pirates" due to their characteristic fighting style.
  • Mooks
    • Airborne Mook: Pirate aerotroopers, flying pirates, aero mines, preeds...
    • Aquatic Mook: Aqua pirates use technology similar to the gravity suit and Aquadrones are built to patrol the depths.
    • Elite Mooks: Pirate commandos, dedicated to hunting the hunter. They are lead by Pirate Commanders, one of whom serves as a boss.
    • Giant Mook: Elite Pirates. Omega Pirate is a Giant Giant Mook. Also Berserker Knights, of which the Berserker Lord is the boss version.
    • Heavily Armored Mook: Armored Pirates Troopers and Armoured Militia. Advanced and assault troopers count too.
    • Kung-Fu Proof Mook: Advanced pirate troopers are resistant to most beams, assault troopers can't be targeted by missiles and only the hyper missiles bother them, the beam troopers are immune to most weaponry besides the beam they are imitating...
    • Mecha-Mooks: Aeromines, Crawlmines, Crawltanks and various drones.
    • Mook Chivalry: In their logs, science team claims the Elite Pirates' weaknesses do not matter because they will be used in coordination with other soldiers, a clear violation of mook chivalry.
    • Mook Mobile: Both their skiffs and their armored tactical carriers.
    • Mook Promotion: Weavel, though to him it was probably a downgrade
    • Nocturnal Mooks: What the Shadow Pirates are supposed to be, but some are too stupid to stay in the shadows.
    • Patrolling Mook: Those in Ridley's ship during Zero Mission as well as Chozodia.
    • Shield-Bearing Mook: Elite Pirates in Prime, Pirate Commandos in Prime 2, several troopers in Prime 3.
    • Slave Mooks: Pirate Militia are made up of criminals forced into service and captured slaves. Disobedient militia supposedly become rations for the real troops.
    • Superpowered Mooks: After they discover hypermode.
  • Only Sane Man: Any pirate writing the log entries about how dumb Science Team and High Command are.
  • Pet the Dog: Apparently some Space Pirates do keep normal pets, as the ones working in the Phazon Mines had to be warned to give them up due to risk of the animals contracting Phazon Madness.
  • Power Pincers: They often have chelae on their forearms that house plasma cannons.
  • Professor Guinea Pig: The entire species is one of these.
  • Sinister Scythe: Combined with Laser Blade or Hot Blade depending on the game and type of pirate. The Space Pirates in the Metroid Prime games are especially fond of these. In the first game, the blades seem to be made of energy as many of the pirate character models do not include a physical blade, yet they can still slash you with one as their melee attack. In the later games most of the pirates have physical blades, but they glow and leave an energy trail when they attack with them.
  • Swiss Messenger: Their presence on Aether at first seems trivial, but then you learn that it was from the pirates that Ing picked up their technology thieving ways. This leads to the Ing possessing every machine on light Aether, nearly destroying the planet with the energy transfer module and stealing most of Samus's power ups!
  • Too Dumb to Live: The Space Pirates as a whole don't seem to have much care for personal safety. Their Science Teams seem positively suicidal; but then they have vapor for brains.
    • They even have to warn personnel not to use Metroids as target practice.
    • Hell, they have to keep reminding personnel not to keep them as pets.
  • Visible Invisibility: Shadow pirates are pretty much invisible by unaided human eyes in the dark; naturally, some will attack in broad daylight, where they are only slightly obscured.
  • Wall Crawl: Varies from game to game whether the current crop Samus is up against can do this.
  • Weak-Willed: According to the manga, Space Pirates are conditioned to follow a strong leader. Beings with even minor Psychic Powers find it surprisingly easy to take command of them.


Why did it have to be bugs?

An insectoid off-shoot of the Space Pirate races, they hail from another galaxy and entered Federation Space in order to help rebuild High Command's operations on Zebes.
  • Airborne Mook: Their wings can be shot off, but they are still dangerous when grounded.
  • Bee People: Exactly how their social structure runs is not clear but they are bee-like and they have a "king".
  • Beware My Stinger Tail: and claws too.
  • Bug Buzz: Learn to hate and fear it in Fusion
  • Eyeless Face: Their larval stage, until Other M decided to give them eyes.
  • Insectoid Aliens: Unlike the "Zebesians" up there, who are more like reptiles in insectoid armor.
  • King Mook: Other M introduces a king Ki-Hunter, who is strangely a Flunky Boss.
  • Natural Weapon: The main difference between them and the other Pirate foot soldiers is that they never seem to brandish any weapons besides those they were born with.
  • Taking You with Me: In Other M, they try to latch onto you and explode if they take heavy damage. Thankfully only in Other M so far.
    • Personal Space Invader: "Super" Ki-Hunters latch on to enemies as a matter of course but thankfully do not explode.
  • Super Spit: The gunk they spit after losing their wings.
  • Third Eye: A large one in the center of their head.
  • Wall Crawl: As zeros, their larval stage.


"East Quarantine Cave has been secured. Specimen remains in the Quarantine area. All experiments have been suspended pending pacification of area. Quarantine specimen exhibits highly aggressive behavior. Its body structure, composed of Phazon ore, appears nearly invulnerable. This has rendered our efforts to train and discipline subject useless as security breaches resulting in massive casualties have occurred. Access is strictly prohibited until further notice."
Project Titan

The least of your problems on Tallon IV...

A truly stunning example of the Pirate's never-quenching desire to subvert science.
  • Attack Its Weak Point: You must use the thermal visor to locate Phazon nodes vulnerable to missile attacks.
  • Golem/Snowlem: It's also a Phazonlem. This results in...
  • Gone Horribly Wrong: Subverted. The Pirates realized it was too difficult to control, and in a rare flash of Genre Savviness quarantined it and left it dormant rather than attempt to control it or completely scrap the experiment, making occasional tests on it and waiting until a way to control it becomes more accessible. Too bad Samus found it before they finished...
  • Mega Manning: You absorb the spider ball from his defeated rubble pile. Because... magnets?
  • Rock Monster: Thardus, the boss of the Phendrana Drifts, which is an entity of living ice and rock.
  • Psycho Prototype: An early attempt at Phazon animation of inanimate material. It backfired spectacularly.
  • Rolling Attack: have fun trying to avoid that one.
  • Shock and Awe: Can generate moderate electric attacks as well.
  • The Worm That Walks: It is not just one singular lump of rock, ice, and Phazon ore. It's a collection of floating rocks in a roughly humanoid shape.

Omega Pirate

"Elite Pirate Upsilon's propensity for Phazon has enabled our research team to infuse it far beyond our safety restrictions, and the results have been extremely encouraging. Its constant Phazon diet has increased its mass exponentially, but it has retained all mental faculties and shows dexterity with all Elite weaponry, including Plasma incendiary launchers and the chameleon manta issued for cloaking purposes. Elite Pirate Upsilon exhibits miraculous healing abilities; when injured, it seeks out Phazon deposits and coats itself in the substance, which instantly mends the creature's wounds. The subject, which we are code-naming Omega Pirate based on these developments, shows potential to be a new standard for our armies. Our only concern at this point is its potential over-dependence on Phazon."
Log 11.232.8

"Finish Her!"

A living testament to the lengths High Command will go to twist and mutate their own kind.
  • Attack of the 50-Foot Whatever: Considering how normal Space Pirates are approximately human-sized, it's quite jarring.
  • Born Winner: The only reason he's so huge and powerful compared to the other Elite Pirates is because he was just naturally born with a superhigh Phazon tolerance, so the scientists were able to pump nearly limitless amounts of Phazon into him beyond what would kill most. However...
  • Cast from Lifespan: Science team's research suggests that though he's had literally no adverse effects to the Phazon yet, his lifespan may be short.
  • Code Name: Was originally just 'Space Pirate Upsilon', before being dubbed the Omega Pirate by the research teams.
  • Evil Laugh: He gives a very creepy one while he's cloaked, which is also the cue that he's about to appear in a Phazon puddle and start rebuilding his armor.
  • Flunky Boss: And God help you if it summons Wave Troopers.
  • Healing Factor: Can absorb raw Phazon to grow back damaged flesh and exoskeleton tissue.
  • Invisibility Cloak: Turns one on when his armor is damaged to protect his health bar till it is fixed.
  • King Mook: A king giant mook
  • Phlebotinum Dependence: It will retreat to Phazon puddles to restore its damaged armor. This is also the only performance concern that has been noted by Science Team.
  • Shoulder Cannon: Dual Wielding them, no less.
  • Super Soldier: The largest and most powerful of them.
  • Unwitting Instigator of Doom: It's certainly trying to doom Samus, but as a result of the conditions of its death Dark Samus is essentially born from its remains.


"To think I called this place home once, in peaceful times, long before monsters moved in the caverns below..."
Samus Aran

Watch where you wander...

A mutant abomination that guards the grottoes of Maridia from deep within her watery lair. Supposedly a cross-species experiment between Zebesian Evir's and Urtragian lizard analogues to create a Space Pirate General capable of guarding Tourian to the same extent as her fellow captains: Ridley and Kraid. Possesses semi-sentience and full asexual reproduction of future generations.
  • Beware My Stinger Tail: It can do massive damage. If she manages to grab Aran with those creepy claws of hers.
  • Body Horror: It's a giant crayfish with distorted features and a pustule fat overhang. Also, both of its death animations.
  • Due to the Dead; Her children bury her beneath the sand after her demise. Possibly averted as some fans think they are going to eat her.
  • Eldritch Abomination: An animalistic, gluttonous leviathan that shrieks like a MUTO from Godzilla.
  • Gut Punch: Quite literal, Aran must burst its soft under-belly with a barrage of super missiles.
  • Mama Bear: To her Evir twin-breed offspring. Samus getting near them is her cue to attack.
  • More Teeth than the Osmond Family: In a gaping circular orifice just to increase the squick factor.
  • Nightmare Face: Horribly twisted skulls are growing through her bulbous brain and she has a nasty leech-like sucker mouth with white, mad glassy eyes that make a Great White's look like a puppy's.
  • Sea Monster: Most definitely.
  • Weak Sauce Weakness: Electricity. Consider that she must be filtering water through her shell, gills and body to move so quickly while submerged and her death becomes even more horrific.


"The cold silence serves to punctuate the feeling of death that emanates from this virtually lifeless place... Only one thing is alive and well here... Evil."
Samus Aran

Unknowable. Unkillable.

An ethereal, supernatural, genderless specter that is both intangible and / or invulnerable to any form of attack, except for its single nebulous eye. It is this eye that, when opened, serves as its connection to the material world and can be torn asunder. It feeds on negative emotions and is drawn to the desolate, derelict wrecks of space-vessels; gorging itself on pain, fear and misery to create spirit thralls known as Coverns. Some suspect it to be merely part of a malevolent entity from the different dimension; others, the psychic harmonics of Mother Brain given manifestation once more. Whatever the case: it haunts Samus Aran like a ghost and will never give up its vendetta.

    Non-Affiliated Bosses 


  • Attack of the 50-Foot Whatever: It is huge, though fire makes it shrivel and shrink.
  • Breath Weapon: Can shoot energy balls from its mouth
  • Combat Tentacles: It has turned the plant's roots and tendrils into tentacles
  • Green Thumb: It can spawn thorny growths in attempts to impede Samus's movements and create tiny short lived plants.
  • Nightmare Face: Its floral features have been twisted to resemble a drooling arthropod like face.
  • Plant Aliens: It was a more like a minimally moving not savagely slice you apart while killing the local ecosystem plant turned into what we see by phazon. Flaahgra is really just a hostile cancerous outgrowth though, once it is burned away the flower it sprouted from will remain alive and harmless.
  • Planimal: It has a central nervous system until you burn it out
  • Poisonous Person: In addition to utilizing its own toxins in battle against Samus, it passively leaks out poison into the Chozo Temple's water system, contaminating the whole temple.
  • Power Of The Sun: Needs constant sunlight or it will quickly weaken
  • Puzzle Boss: You have to make it retract its roots to damage its sensitive areas at its base, attacks to its body are almost pointless so long as it is bathed in sunlight.
  • Red Herring: You'll have the chance to read scans about a great poison before encountering it. While Flaahgra is the source of the poisonous water int the Chozo Temple (which disappears once it's defeated), it is not the great poison referenced in these scans..
  • Super Spit: Spews poisonous fluid that spawn acidic plants
  • Sinister Scythe: It has these as hands.
  • Wake-Up Call Boss: For anyone who neglected to find the charge beam before approaching it or does not think to use it.
  • You Will Not Evade Me: The first thing it does is seal off the exit with vines.


  • Attack Animal: The Ing were said to breed and raise worms for various tasks; these were, if not their guard dogs, then at least something they left in the general area to ensure nobody got the dark suit or stolen planetary energy.
  • Call Forward: The destruction of the dark sphere looks just like that of Zebes.
  • Casting a Shadow: Not on their own, but once attached to the dark sphere, they will be capable of flinging safe zone-neutralizing shots of darkness or channel thick purple energy beams. The dark attacks seem to take on a different characteristic around the dark sphere, which prevents you from clearing away beacons the way you normally do.
  • Feed It a Bomb: The only way to damage them is to let them inhale you and then lay a bomb in their mouths. Rather than really letting them inhale you, you're hitting them hard enough to make them fall over and gasp for air... at which point you give them a metal ball laying bombs. Damage to their hides will only slow them down till you directly hit the internal organs it seems.
  • Sand Worm: While not to Dune levels, they are close. Very large sand worms Amorbis are.
  • Suicidal Overconfidence: Averted for your benefit. Kill one and the others will flee and never bother Samus again. The battle would have been much tougher if they had merely waited until two were dead, much less fighting down to the last worm
  • Third Eye: That makes nine between them
  • Wolf Pack Boss: What's that? You've beaten giant worms before, not too long ago in this very game you say? Fine, here's three of them bigger than any we threw at you before!
  • Wormsign: The sand above where they're about to emerge will begin to flow outward as if being pushed up from below. If the sand you're directly standing on is doing this, MOVE.


  • Barrier Change Boss: While any weapons will damage it, during the second phase it switches between being weak to light and dark.
  • Big Creepy-Crawlies: A dragon flyish alien
  • Enemy Mine: Some ing-possessed creatures may show up while you fight it; naturally, they focus on you, not the giant bug that provoked them.
  • Eyeless Face: The larva form.
  • Giant Flyer: Once an adult.
  • Grimy Water: Lives in and shoots it at you.
  • Hermaphrodite: Self-impregnating, no less.
  • Making a Splash: In all forms really but in the most literal way during the larva sequence. That's when you shoot it.
  • Marathon Boss: One of the longest boss battles in the series.
    • Deader Than Dead: You can scan Chykka's corpse after the battle is over (nearly every other boss either fades away or explodes), which basically goes to assure you, in no uncertain terms, that the creature is finally dead:
    "Bioscan complete. Target Chykka has been terminated. Lifesigns are at flatline. No regenerative ability in effect. No evidence of symbiotic corpse possession. Resurrection does not appear likely."
  • Rapid Aging: It started out as an egg.
  • Sequential Boss: The first phase is against its larval form, which for all intents and purposes behaves like a fish in the dark waters. After being defeated, it retreats and rapidly metamorphs into its adult stage, which is a massive wasp-like insect that alternates between light and dark forms.
  • Super Spit: Its larval form spits digestive juices on you


  • Attack of the 50-Foot Whatever: Nintendo Power had an article on this boss with a side by side comparison of its model with Samus's, asking if that was a fair fight.
    • Humongous Mecha: And possibly THE largest boss in Metroid history. The Command Module is nearly the size of Samus's ship.
  • Demonic Possession: Presumably, it had joined the war against all living things before the Ing took it over.
  • Everything's Better with Spinning: Sometimes, during its first phase. Subverted, since getting sucked into a top-like mech to be battered is anything but better.
  • Finishing Stomp: There is a good chance you won't be finished, but you deserve to be if you let the robot step on you.
  • Improvised Platform: You use its mangled defeated body as one.
  • King Mook: It is essentially a gargantuan Quad robot. Even down to the Command Module and Main Body being able to fight separately.
  • Mighty Glacier: It is fast enough to keep you in its sights but will not be winning the 100 meter dash in its current state. Luckily for it there are walls that prevent Samus from simply running away.
  • More Dakka: It also has missiles and bullets to spam.
  • Red Eyes, Take Warning: Subverted; when the Ing start using it, its eyes go from red to blue. When they start to turn red again, it means you are winning.
  • Some Kind of Force Field: You need the Echo Visor to turn it off.
  • Third Eye: For whatever reason
  • Yin-Yang Bomb: Its Annihilator Beam.
    • Homing Projectile: Somehow it not only shoots energy given off from an annihilation reaction but makes it home in on you. With one of these under their control is it any wonder U-mos predicted the Ing's ascension to an interplanetary threat?



  • A.I. Is a Crapshoot: Not of his own programming. He has been corrupted by Phazon.
  • Ambiguous Gender: One would assume he would have none at all, being a robot but the scan visor says that Helios is male.
  • Beam Spam: One of the shapes it may take with its swarm is diving them up into rings of six, and having each ring fire a powerful beam at you.
  • Chainsaw Good: Though Helios primarily relies on his Swarmbots for attack and defense, he is not completely defenseless on his own.
  • Deadly Disc: One of the shapes he may take with his Swarmbots.
  • Hive Mind: It controls thousands of Swarmbots through wireless communication.
  • Killer Robot: Helios's original function, much like the swarm bots, is unknown but phazon has turned them into killers
  • Meaningful Name: The Swarmbots all revolve around Helios, both figuratively and literally in many cases.
  • Multiarmed And Dangerous: The robot has four arms
  • Rolling Attack: Another of his forms.
  • Spin Attack: One form he may take is to lay himself on the ground and have his swarmbots form a tornado-like swirling shape above it, and proceed to slide across the ground.
  • Synchronized Swarming: He likes five formations in particular
  • The Worm That Walks: One shape it takes is to have the Swarmbots form into four limbs for a vaguely human-like appearance.


  • Body Horror: As if its organic components weren't horrific enough already, as it takes damage in Fusion, its face begins to melt off.
  • Collision Damage: Loves to collide with you, almost more than shoot you.
  • Cyborg: Inverted. It's a machine with organic components installed. Those organic components are what let the X infect it, much like its fellow machine-with-organic-parts, the B.O.X. security droid.
  • Gravity Master: It can slow Samus down, stop her ability to space jump and cause her missiles to prematurely crash before hitting it. It can not unload its full arsenal while doing this however.
  • Knight of Cerebus: Everything goes from bad to worse in Fusion when he shows up, because in order to escape Sector 5 after destroying him, Samus must take a lengthy detour off the map, setting her on an inevitable course to The Reveal.
  • Larynx Dissonance: In Other M, without the reverb of its mask and the drone of its gravity field, its voice sounds less like a looming bioweapon and more like a crying baby. In Fusion, it sounds like wind through a forest canopy, which is a bit more dignified but still not quite as low pitched as you'd expect for something of its size.
  • Lowered Monster Difficulty: Inverted thanks to the series continuity but he is much more difficult in Fusion than in Other M, especially if you fight him with the gravity suit in Other M.
  • Meaningful Name: You guessed it, it's That One Boss. Fusion telegraphs the hell out of the impending Difficulty Spike, with the computer unable to track its position and Sector 5 having been laid to waste by the time you show up.
  • Nightmare Face: Six horrid little yellow eyes and saggy, snot-green skin. In Fusion the face starts to melt as you shoot it!
  • Psycho Prototype: Even before it was infected by the X, Nightmare had attacked Samus on the BOTTLE SHIP and caused damage to Sector 5 on the B.S.L.


The Chozo

"The Chozo... Over millennia, this bird-like race of creatures made incredible technological and scientific leaps. Traveling at will through space, they built many marvels across the Universe. Technological wonders of unfathomable complexity and cities unmatched in beauty. They shared their knowledge freely with more primitive cultures and learned to respect and care for life in all its forms. Even as their society reached its technological peak, the Chozo felt their spirituality wane. Their culture was steeped in prophecy and lore, and they foresaw the decline of the Chozo coinciding with the rise of evil. Horrified by the increasing violence in the universe, they began to withdraw into themselves, forgoing technology in favor of simplicity. Tallon IV was one of the several refuges they built - a colony bereft of technology, built of natural materials and wedded to the land and its creatures."
Metroid Prime Manual

"The statues are our sentinels: blind but ever watchful, they are and have always been, repositories for our most precious secrets and strongest powers. The crafting of each is a long and sacred process, performed only by those Chozo who have lifetimes of experience in such things. We have left these relics on planets across the solar system. Some are merely reminders: silent emblems of the Chozo that serve as icons of peace in lands that know only war. Others wield subtle strength, exerting their influence in ways beyond the understanding of mortal creatures. Still others are guardians of our secret ways, and these can be as terrible as they are beautiful. Those who respect and honor these relics will know the friendship of the Chozo. Those who deface or destroy them will know our wrath, unfettered and raw."
Tallon IV, Hieroglyphic Engravings

"We shall do all that we can to aid her, for she bears our legacy as she bears the ancient armour and weapons of our people."

  • A Fate Worse Than Death: The Chozo on Tallon IV were pulled from their Higher Plane of Existence by Phazon. They managed to deal with it and return, except for the many that were twisted into insane ghosts by it while sealing the bulk of the stuff away. They had to be left behind. They are the turned.
  • Ascend to a Higher Plane of Existence: It's stated in Metroid Prime that at least some of them have done this.
  • Beware the Nice Ones: Samus and the Metroids are proof enough that you do not want the Chozo mad at you.
  • Canon Immigrant: Old Bird, one of Samus's Chozo mentors/adoptive parents, appears in the Japanese version only endings of Metroid Fusion (which you can thankfully unlock in any version of Zero Mission), and makes a blink-and-you'll-miss-it cameo appearance in Metroid Zero Mission in one of Samus's flashbacks. Old Bird first appeared in the Nintendo Power Super Metroid comic and was later imported to the manga (along with Chairman Keaton and Chief Hardy). Some speculate that the second Chozo in the engraving at the end of the game may be Aran's other Chozo mentor, Gray Voice.
  • Do Androids Dream?: Elysians installed the ability to "dream" in themselves so that they could be alerted to happenings while they "hibernated". They claim to have seen forms of their builders in between their operational sessions, but given the Talon IV Colony's established abilities, there may have been more to that incident than what the installed dreams were supposed to cover.
  • Doom Magnet: Whatever they touch, be it planet, species, or individual, is universally ill-fated in some way. Planetary destruction and being driven to the brink of extinction happen a lot where they've been.
  • Endangered Species: In the manga, it is implied that the only remaining Chozo are the handful on Zebes and they are basically trying to finish their work on "Metroid" before they go extinct. The games are more vague but make it clear the Zebes Chozo were just one small group of a nomadic civilization, that may be endangered, extinct or simply out of reach.
  • Friend to All Living Things: The only creatures they ever had to take action against were the X. Every other species was fine to them, as shown by the wildlife on Zebes and Tallon IV.
  • Gone Horribly Wrong: Both the Metroids and Mother Brain were created by the Chozo to make SR-388 and Zebes nicer places to live. In both cases, the Chozo got a lot more than they bargained for.
  • Idiot Ball: This is what the manga says brought down their civilization. When their technology had advanced to the point they could live for hundreds to thousands of years with near perfect health, they started to really get caught up in their own desires (at this point, they were still warriors), but despite the fact they could live long, they started feeling the effects of old age and had to give that up. It was only then that they realized that their entire civilization had squandered their youth and forgot to reproduce while it was possible. As a result, they became the peaceful scientists who helped form the Galactic Federation as a measure of immortality for their species as they started a near millenia of watching their own civilization die.
  • Mistaken for Granite: The first Chozo Statue in Super Metroid seems inanimate until you take the powerup it holds and try to leave, at which point the exit seals and it attacks you.
  • Organic Technology: One possible explanation for the X parasites being able to duplicate Samus's suit and one of their statues, as well as how the Elysians were corrupted by Phazon. Whether or not that's really the case, it's interesting that their solution to the X Parasite was to create a X-immune life form which could hunt it, rather than some non biological method of containment.
  • Our Ghosts Are Different: Some left their bodies and the game's dimension behind; later, they returned to the game's dimension, still without those bodies. The ones that got stuck in the game's dimension because of phazon madness are what the other creatures call ghosts. The Chozo call them the turned.
  • Perfect Pacifist People: The Chozo have evolved to a point in which they live in harmony with nature, shunning violence and destructive technology. Of course, they were warriors once, and were able to create the advanced armor that Samus uses.
  • Precursors: They seem to zigzag all the precursors tropes. Their neglectfulness is mentioned below, their Abusive Precursors status is established by the fact they made the Metroids, then subverted into Benevolent Precursors both by the below mentioned upgrades, and the fact they originally made the Metroids to stop something worse.
    • Abusive Precursors: The Turned! It is not their fault though, as phazon has an even stronger effect on them in their ascended state and the other Chozo advise shooting them if encountered, as an act of mercy!
    • Benevolent Precursors: While it is true that they weren't able to do much in their own lifetimes, they actively worked to put in place a system for Samus to redeem them by seeding various worlds with power suit upgrades for her to collect.
    • Neglectful Precursors: Zigzagged. Not even they, with all their technical and spiritual skill, have what it takes to take care of the doom that follows them around like a puppy they fed, leaving it all for Samus to clean up. On the other hand, they have limited ability to make prophecies, and make a point of preparing for each one they find feasible. The Tallon IV colony stocked up their ruins with power suit upgrades specifically to help Samus save the day in the future, and it's implied that the Chozo on other worlds did the same.
  • Proud Warrior Race Guy: What they used to be. Prime shows they consider Samus's weapons to be ancient, but whether that has to do with being primitive to them at this point or simply because no one's bothered to choose the warrior's path for so long is up for debate.
  • Psychic Powers: Of the subtle variety.
  • Seers: Those on Tallon IV had visions of the future, but they were not perfect visions.
  • Space Elves: In their warrior phase they were essentially Space Tengu.
  • Steam Punk: They have done some dabbling in this, as seen by the observatory they left on Elysia.
  • Sufficiently Advanced Aliens: A major reason why Samus's suit has such impossibly advanced technology is because these guys didn't have to worry much about regular physics.
  • Technical Pacifist: For a race sworn not to hurt other living creatures, it seems odd that they'd train the galaxy's greatest Badass (and create its worst living weapons...)
  • We Have Become Complacent: The Tallon IV colony had decided to give up all but the most basic technology and live in harmony with nature. This unfortunately made dealing with invaders and star born plagues more difficult but they did discover some new tricks, such as prophecy and managed to Mac Gyver enough things till Samus came, like their visions foretold. Still some of the machines found on Tallon V are mere first and second generation equivalent drones, from a society with multiple millennia of continuity.

The Metroid Hatchling

"I next fought the Metroids on their home-world of SR388. I completely eradicated them except for a larva, which after hatching, followed me like a confused child..."
Samus Aran

The Last Metroid

  • Androcles' Lion: A major plot element in the series. In Metroid II, Samus is tasked with exterminating the Metroid species, but stops at killing a newborn showing no hostility toward her. In Super Metroid, the baby is kidnapped, and Samus goes to get it back. Samus is eventually reunited with the Metroid, who is now gigantic after being nursed by the Space Pirates. It starts to swallow her, but recognizes her as its surrogate mother, and lets her pass. At the final fight with Mother Brain, the baby sacrifices itself to heal Samus and give her the hyper beam. This episode is the major thematic introduction for Metroid: Other M. Later in Metroid: Fusion, in a posthumous example. After Samus is infected by the X parasite, a cell sample of the same baby Metroid is used as part of the cure that destroys the parasites inside her and saves her life.
  • Big Damn Heroes: During the final boss fight of Super.
  • The Cavalry: And sort of continues to be posthumously.
  • Chekhov's Gunman: In Super Metroid you could get the brief impression Samus was going to drop it off and do something else but the whole game turns out to be about it, especially the end of it.
  • Heel Realization: Just as it's about to finish Samus off, it recognizes her as its "mother" and chirps apolgetically.
  • Heroic Sacrifice: One of the most iconic examples of the medium.
  • Implacable Man: None of Samus's weapons can so much as slow down the Super Metroid, not power bombs, not the ice beam, not beam combos. Mother Brain had weapons able to damage it though and the hyper beam was not one of them in the original take as she killed it after it was stolen. (in Other M, Mother Brain uses the Hyper Beam to kill it, which begs the question of how exactly Samus got it? Maybe she's just remembering the events wrong?)
  • Insect Queen: Since Other M's Metroid Queen is cloned straight from the baby and only special infants have the genetic coding to become queens, it would appear that the hatchling was indeed an infant Queen. (Note to the Chozo, there is a reason real hive species don't work this way!)
  • Last of His Kind: At least until it is later cloned by the Federation, which still does not bode well for Metroids in the long run, if they are all descended from one individual.
  • What Measure Is a Non-Cute?: Subverted as far as Samus is concerned.
  • Your Size May Vary: In Super Metroid they were not kidding. It had grown gigantic, covers Samus completely as opposed to they way Metroids usually just latch onto her head and was half the size of Mother Brain. The Other M version is significantly smaller, half the size of Samus at best.

The X

"The creature took on the host's memories, appearance, abilities, everything. It sucks everything dry. Utterly terrifying. Can you not see that if a mimic such as this were to infiltrate a population, it could replicate almost indefinitely! With evil taking the form of an ally, the galaxy could be overthrown. It is truly the worst kind of evil... it has no name, but... we call it X."
Old Bird

Man, is the warmest place to hide.

  • Aquatic Mook: They create some mermaid pirates if you stick around to see it.
  • Artificial Brilliance: Mid-way through the game you'll encounter some blue X that are very cold. This is at a point in the game where you are very vulnerable to cold and will have to avoid them like the literal plague they are in a nasty inversion of Power-Ups. Once you collect a power-up that allows to absorb them safely though, the blue X will flee on sight after seeing that their tactic no longer works. This is the first hint that the X may be more sentient than first thought.
  • Artificial Stupidity: Despite the fact that the SA-X is the most powerful enemy in all of Fusion, and despite the X's ability to copy any organic body part, it apparently lacks a brain.
  • Back from the Dead: Done to the Space Pirates as well as Nightmare and Ridley by mimicking them.
  • Big Bad: The SA-X.
  • Body Horror: Through the process of infecting hosts, the X either take over or mimic the body, typically while mutating the original form into something much worse. Samus doesn't have even have to be fully infected for this trope to come into play for her.
  • Cosmic Horror Story: They'd fit right in one just as well as any eldritch creature, which is why Metroids were made.
  • The End of the World as We Know It: This is more or less what happened when the X made a comeback on SR-388. It's also what would have happened elsewhere had the Galactic Federation gone through with their plans to capture the SA-X.
  • Enemy Mine: The SA-X decides to assist Samus in destroying an escaped Omega Metroid, apparently considering it to be the greater threat.
  • Expy: Of The Thing
  • Gameplay and Story Integration: The X being all your pick ups.
  • Genetic Memory: They retain the intelligence and memories of what they transform into.
  • Geo Effects: They are smart enough to make use of them, particularly their use of cold areas to ward off Metroids. This could only go so far, though, since Metroids outgrow their ice weakness anyway.
  • Heartbeat Soundtrack: Heard when the SA-X is near, but when not in "Chasing you down and trying to kill you violently"-mode. This is basically its Leitmotif.
  • Humanoid Abomination: Aside from the SA-X, their efforts to mimic humans end up failing, as it results in them becoming gelatinous humanoid blobs wearing lab coats instead. They end up refining the process eventually, to the point where a Core-X perfectly mimics a scientist in order to set Sector 3 on the fritz.
  • Implacable Man: The SA-X; in fact, don't even think about fighting it until the game says you can. Just run, run or hide.
  • Informed Attribute: While the manga did illustrate that the native life on SR388 fled from X on instinct and were still getting wiped out despite this adaption, it failed to demonstrate how they were "evil" or how anyone could conceivably use them as a tool for infiltrating the Federation (the game makes it clear their only drives are eat, reproduce and eliminate any perceived threats. It then stated anyone who thought they could be controlled was kidding themselves).
  • Intangible Man: Yes, they can go intangible and ignore most physical barriers. However, it is implied by the powerbomb that large enough explosions can still affect them, and it'd stated by Adam that big enough ones can kill them.
  • It Can Think: At first, they seem like a mindless species of parasites running purely on instinct. Over the course of the game, you begin to learn that they're ruthless, intelligent, and capable of acting against instinct for their own ends.
  • LEGO Genetics: Not only can they mimic the DNA of their prey, but they can combine, mutate, and alter that DNA as they see fit to produce ever more dangerous forms.
  • Let X Be the Unknown: Real creative, Federation (Chozo in the manga)
  • One-Winged Angel: SA-X, though it later turns into a gigantic hulking monster that can be defeated with three charged shots. Just don't let it hit you.
  • Power-Up: Interestingly, while they're the main threat of Fusion they're also your main source of energy.
  • Spikes of Villainy: They seem to add them to a lot of the things they mimic and the Core Xs are loaded with them.
  • Stealth Pun: The X infect a machine with the acronym B.O.X. So, it's the X-Box. Core X come in two varieties, referred to as Fast and Hard. Fast X and Hardcore.
  • The Soulless: Never had one to begin with.
  • The Virus: Though not literally viruses, you do fight both infected victims and mimics made by the X using their hosts' DNA.
  • You Will Be Assimilated: They even retain the host's knowledge and memories.

The Luminoth

"It is told that the Luminoth were not born of Aether, but of the stars. In the early days, we roamed the greatness of the void, bathing in the glorious light of a thousand stars. We met a vast number of enlightened minds... the N'kren, the Ylla, and the Chozo among them. Each of them, we found, had claimed a homeworld and formed a deep bond with it. In time, we decided to do the same. Our search for a home took us through the cosmos. For many a great cycle we roamed, yet a place to call our home eluded us. In time, we began to despair, feeling the search was in vain. We considered remaining among the stars until a scout returned with news of a world unlike any other. When we first beheld Aether for the first time, so great was her beauty that we forsook the stars forever to live upon her surface. From that day forth, the Luminoth were of Aether, our blessed paradise."
Lore of Light

"Through vigilance and strength, we create peace."

  • Always Lawful Good: Though we really only learn about their species wide interactions, founders, heroes and the desperate actions they take in the face of any enemy bent on their annihilation, so anyone could come off like that.
  • Antimatter: The light of Aether and the atmosphere of Dark Aether have given them away to contain antimatter and weaponize the energy let off by annihilation.
  • Astonishingly Appropriate Appearance: They are basically humanoid moths. So, it's natural that they would have a deep attraction to light.
  • Bilingual Bonus/Punny Name: Their species name is basically a combination of the Latin "lumen" for light and "moth."
  • Badass Preacher: The Luminoth usually speak about peace and all that, through strength and if neccessary war, and come off as a race that would rather not fight. But as soon as the Ing invade, they wasted little time in preparing for war, and while they failed, they still did a pretty good job. Added to the fact that if you scan the bodies of some of the dead ones, you'll see that the grand majority went down fighting, or at least holding their post; a notable example of the latter would be one female Luminoth that held her post even though she was starving to death. The Luminoth are pretty hardcore.
    • Special mention should go to J-Stl and A-Kul. J-Stl killed at least 100 Ing in his last stand, and who knows how many he killed in total. A-Kul: went into Dark Aether, a terrible dimension filled to the brink with Ing that would kill her the second they got a chance and whose very air was deadly, found one of the ten keys to the temple that had all been hidden by the Ing, fought her way to the Sky Temple, and managed to place it there AND leave clues to the other keys before dying.
    • The Sentinels of the Temples are perhaps the epitome of this, especially since they probably really are preachers. Scans reveal every one of them went down fighting. The one in Agon died while fending off innumerable Ing hordes, finally succumbing to superior numbers. The one in Torvus was possessed numerous times, and fought off each of them. The Ing finally realized that they couldn't break his will and killed him. And the one in the Sanctuary Fortress was so badass, the Ing had to turn his own weapons of war against him, unable to defeat him themselves.
  • Computer Virus: For once, the technology level and earlier compatibility patches pretty much justify the Rezbit's hacking and virus uploading abilities. The question here is why the Luminoth would make the little thing so good at delivering them in the first place.
  • Cyber Punk: Their Sanctuary Fortress's design seems at least partly inspired by it, especially compared to their stone temples and hive like dwellings.
  • Going to Give It More Energy: This is why the Luminoth first designed the Dark Beam in Echoes. It didn't work. They then designed the Light Beam, which was much more effective.
  • Higher-Tech Species: They developed their unique technology through a combination of contact with the Chozo and their own experimentation on Aether. In fact, they might very well have gotten the chance to join the Chozo as Sufficiently Advanced Aliens had they not gotten embroiled with the Ing.
  • Insectoid Aliens: They're basically giant moths.
  • Kneel Before Frodo: What they do after Samus destroys the Ing for good.
  • Light Is Good: Sort of. The light of Aether is supposedly part of what makes their technology possible and it is what kept the Ing from immediately overrunning them, but from Federation data, it can be implied it is also what makes Aether "dimensionally unstable", which is what allowed Dark Aether to form in the first place.
  • Magnetic Weapons: Mekenobites use magnets to walk on the walls and ceilings of Sanctuary Fortress and to propel projectiles at enemies.
  • Most Writers Are Human: The fact that Samus is fighting to help a species of humanoid moths against a species of very definitely non-humanoid creatures is significant.
  • Hopeless War: Both against the Ing and their own machines. The machines as a whole aren't able to combat the Ing well either and are not priority targets for them beyond extra weapons systems. This means whether possessed or free, most of them are against the Luminoth.
  • Moth Popsicle: All but U-Mos are in stasis until the crisis is over. In the final scene, they all get out and bow down before Samus in gratitude.
  • Psychic Powers: More than one of them had these, at least, but it is not clear how many.
  • Robot War: The machines they created for war, and even those for peace, decided that all living things must die while the Luminoth were already in the middle of the Ing war. Only the most basic maintenance bots remained loyal, though they weren't of much help, having no combat ability.
  • Space Elves: Of the "Enlightened Mystic" variety, thankfully.
  • Starfish Language: They have a three dimensional writing system, for starters. Samus's scan visor cannot even break through much of it at first.
  • Weather Control Machine: One of the marvels they made use of.

The Ing

"It was the end of peace on Aether, for a new race was born that day on the dark filled with hate and terrible power. They are the Ing."

'Ing' means terror

  • Always Chaotic Evil: Their society promotes the hunting, killing and enslaving of everything that is not an Ing.
  • Artificial Brilliance: The Ing have no problem with bumrushing you out of a safe zone if they have lots of health left, and the ones that don't will snipe you with energy beams. Also, if you kill enough Ing with a supercharged safe zone (by using the Light Beam on it), they'll just stop approaching them entirely and always fire the beams.
  • Authority Equals Asskicking: The Emperor Ing is described as the most powerful of them by U-Mos. It is also the only Ing who can survive exposure to Phazon without using a Metroid host.
  • Back from the Brink: All that time between Samus making planetfall and getting the Energy Transfer Module? She could very well have gotten possessed by an Ing had she not been extremely lucky.
    • Not only that, but they would've succeeded in killing the few remaining Luminoth and stealing the last of the Light of Aether had Samus arrived at the Great Temple any later than when she did. The light world would've been destroyed as theirs became the default one, and they would've likely expanded beyond Aether, as warned by U-Mos. The only two known species that they probably wouldn't completely screw over are the Phazon beings, which they descend from, and the X, both of which possess similar qualities to the Ing.
  • Barrier Change Boss: The Emperor Ing after metamorphosis.
  • Beam Spam: Warrior Ing can channel energy from other dimensions through portals. They primarily use this tactic to push targets out of safe zones.
  • Bee People: They behave like them.
  • Big Bad: Emperor Ing in Echoes.
  • Born Winner: Like the Omega Pirate in the first Prime, the Emperor Ing has a super-high Phazon tolerance and thus gains a lot of power from it. And also like the Omega Pirate, this comes at a price: it loses its mind.
  • Casting a Shadow: The species as a whole can do this, to an extent, being amorphous blobs of what is essentially darkness.
  • Dark Is Evil: Not every species on Dark Aether is necessarily evil but these guys are by far the dominant force on the planet and are very evil.
  • Demonic Possession: What they're good at.
  • Demonic Invaders: They are aliens, but read the lore that describes how they were discovered; it reeks of the trope.
  • Elite Mooks: Hunter Ing and Ing Storms, both capable of flight.
  • Endangered Species: The only Ing still alive are the ones who managed to possess another creature, as they can't live on Aether by themselves. The space pirates have a darkling Metroid on display at one of their bases, as revealed in a Prime 3 scan.
  • The Heartless: "The Ing are creatures of shadow and darkness, knowing nothing of peace or mercy."
  • Humanoid Abomination: They possess the deceased Galactic Federation troopers on Aether to use against Samus, but have trouble achieving full parasitic fusion with dead bodies; the furthest they ever got was increased stamina with the Missile Trooper, though all have very low agility and response time.
  • Intangible Man: Hunter Ing; they still can't handle the light of Aether, but Samus's light beam is trivial to them.
  • Invisibility: Some Ing have methods of this, to the point they can hide from echolocation and sonar. Mostly notoriously their flying caches.
  • Mini Mook: Ing Larva and Ingstorms.
  • Mook Carryover: They make a point to possess Pirate Troopers, as they are already used to following orders.
  • Night of the Living Mooks: When they use the dead marines to attack Samus.
  • Rite of Passage: Ing are forced to fend for themselves as larva, then fight dangerous opponents after maturing. The idea is to make the young ones rely on each other and hate all other lifeforms, and it seems to work.
  • Starfish Aliens: Unfriendly ones at that.
  • Stealth Pun: In Echoes, the Sub-Guardians are Ing-possessed creatures with a "Boost Guardian, Grapple Guardian, etc" naming convention. Boost Ing, Grapple Ing...
  • The Swarm: Some areas in the Sky Temple Grounds and Ing Hive have clouds of tiny Ing called Ingstorms. Stepping into them without the Light Suit will kill you in mere seconds. Don't do it.
  • Taking You with Me: After their world begins to die, several Warrior Ing attempt to prevent Samus's escape from Dark Aether so she'll die with them, but she just jumps over them and continues going.
  • Wall Crawl: All of them that are mobile but don't fly can seemingly do this.
  • Wall Master: Darkling Tentacles
  • You Will Be Assimilated: They seem to take a page from the X Parasites, in that both mutate other creatures into new forms. The Ing possess live hosts, however; their attempts to bring back dead bodies were pretty pathetic (though freaky). All X need is DNA; they eat the prey first, then start making copies. Before you write the Ing off as less dangerous, know that they can possess Metroids, which X cannot work with at all.


"Darkness... coming..."
Aurora Unit 313

The Great Poison

  • Applied Phlebotinum: It's a mutagenic substance that the Space Pirates exploit for a power-up.
  • Artistic License – Nuclear Physics: Phazon, a highly radioactive, nearly uncontrollable substance that may possibly be alive, originating from a supposedly sentient planet, is attempting to spread everywhere and it's supposedly stable.
  • Big Eater: It usually kills most organisms then absorbs it, turning the corpse into Phazon. Fitting, considering it's status as The Corruption.
    • Cradle's interpretation...
    "It eats relentlessly, worming out life wherever it blooms and corrupting what it cannot kill."
  • Bigger Bad: In the Prime trilogy. It is the source of all the conflict, but other beings — Metroid Prime and Ridley in the first game, Emperor Ing in the second game, Dark Samus in the third — serve as individual Big Bads in their own games.
  • The Corruption: Phazon usually prefers to kill and absorb weaker beings, but if the victim is strong enough, it is instead mutated and becomes an agent of Phazon.
  • Eldritch Abomination: Revealed in Prime 3 to be basically a huge transdimensional being with a heart the size of a planet. The Chozo's whole ascending to a "higher" dimension thing? That actually reduced their ability to fight it.
  • Fungus Humongous: There are some giant mushrooms that seem very heavily saturated with Phazon.
  • Genius Loci: Its core is Phaaze, a huge sentient planet.
  • Green Rocks: Phazon has quite a diverse range of uses: mutating plants and wildlife, being weaponized, driving creatures and several major characters insane, etc.
  • Law of Chromatic Superiority: Though most Phazon encountered in the game is blue, there are strains of "Red Phazon" found occasionally, stated to be far more potent and dangerous than the blue stuff. It serves as a hazard in the Impact Crater in the first game, and in the third game the Pirate Commander is outfitted in Red Phazite armor, which proves much more durable than the standard blue Phazite.
  • Nonstandard Game Over: When Samus spends too much time in Hypermode, the Phazon will corrupt her and turn her into a replica of Dark Samus.
  • Psycho Serum: Phazon tends to drive its infectees insane if it does not kill them.
  • Scenery Gorn/Scenery Porn: In the midst of Phazon twisting environments into strange forms, it does make things very pleasant to look at.
  • Sentient Phlebotinum: It seems to be more self aware than grass, but does not seem to be particularly intelligent.
  • The Virus: Long term exposure that does not result in death changes organisms for the worst. It becomes even more so when space pirates start using an actual virus to infuse a strand of it into creature's DNA. Ironically the literal viral phazon has a much lower fatality rate.
    • Leviathans act almost like real viruses. Once Phaaze produces a mature Leviathan, it travels towards a suitable planet to infect, then it starts to spread Phazon until the planet is essentially another Phaaze.
  • Toxic Phlebotinum: Everything it doesn't kill, it turns into a violent killing machine, usually with a shortened lifespan. The space pirates discovered a strain that could be integrated into an organism's DNA and give it a higher tolerance to the substance, but it still only worked in one case. Three if you count Samus and Metroid Prime.
    • If you break canisters of Phazon around Ing, they die. The Ing and the toxic alternate dimension they live in could arguably be made out of literal pure evil, and are in fact a byproduct of Phazon hitting the original planet, and they still can't take it! The only being on all of Aether that does survive it is the Emperor Ing, who proceeds to hoard it, but still ends up losing its mind. It's possible this is why the Ing are so violent.
  • Uniqueness Decay: Phazon is a new substance in the first two games, with the Space Pirates going to great lengths to secure sources; in the third game, you can't walk two feet without bumping into phazon or something that runs on phazon (and that's not even counting yourself), just as planned.

Metroid Prime / Dark Samus

"Investigations into a possible ingress point for the impact crater continue to meet with failure. The shield of strange energy that protects it is impermeable, and all attempts to tunnel past it have proved fruitless. Our continued futility in this matter is made all the more significant in light of recent life form readings we've discovered emanating from deep within the crater. Analysis of the readings indicates that a massive creature is gestating in there, absorbing enormous amounts or Phazon from the Phazon core at the heart of the impact crater. This discovery makes accessing the crater doubly important - not only will it open the door to the vast deposits of Phazon within, but it will also lead us to this creature, whatever it may be..."
Log 11.156.9

"Our scanners have detected the remains of Dark Samus, who has revived herself within our Phazon storage. Surely, we are cursed. The fiendish shrew consumed all of the Phazon, then wiped out a third of the crew in a matter of minutes. Now she moves at will through the halls of Colossus, using her witchery to beguile the minds of the crew. We are unable to call for aid, and only a few of us remain to stand against her. All is lost."
Captain's Log

The Core Essence
The Black Demon
  • A God Am I: She takes over the Space Pirates in Corruption and forces them to worship her.
  • Ax-Crazy: Dark Samus during the events of Metroid Prime 2: Echoes was certainly depicted as being completely insane, namely due to being imbalanced at a molecular level, almost to Kefka Palazzo levels.
  • Badass: Let's see: She manages to fight Samus multiple times and survive, something only Ridley accomplished prior, she manages to survive a destablizing dimension, gets revived in Corrruption and manages to take control of a whole planet of Space Pirates, including RIDLEY, curb-stomps and corrupts all four Hunters and manages to turn three of them against Samus. Put simply: Ridley might be Samus's nemesis, but Dark Samus is arguably her most powerful opponent yet.
  • Bag of Spilling: Just as much as the real Samus, it seems.
  • Barrier Change Boss: And it is foreshadowed in some Pirate data, too.
  • Big Bad: Of the Metroid Prime Trilogy.
  • Breath Weapon: As Metroid Prime she can spit an ultra-frigid breath from a "mouth" on the underside of the armor stolen from the Space Pirates.
  • Broken Bridge: Invoked and subverted in that Samus is able to cross the gap despite her efforts.
  • The Chessmaster: In Corruption she taints the bounty hunters with Phazon.
  • Combat Tentacles: Can project these from her armor. In fact, these are how Dark Samus was made!
  • Curbstomp Battle: Her skirmishes with the space pirates on Aether all see her quickly cut through them. Then she applies it to the Hunters from Prime 3, in case anyone had doubts about her threat level already.
  • Dark Action Girl: Sadistic and violent, Dark Samus is the antithesis of Samus Aran.
  • Deflector Shields: Has them at a couple points.
  • Demonic Possession: Tries her hand at it in the third game.
  • Determinator: No matter how many times she is put down in Echoes, she keeps on coming back to manipulate the Aether situation to siphon as much Phazon as possible.
  • Doppleganger Attack: In Corruption, and it calls back to Echoes despite not being present there.
  • Early Bird Boss: Some of her abilities are things Samus could duplicate or at least counter if the power-ups were present in the Prime series. She also uses super missiles long before the player can get them.
  • Evil Makes You Ugly: The Final Boss battle in Echoes has Dark Samus visibly disfigured by Phazon overload (and the Skull for a Head even brings a Call Back to the original Metroid Prime)
  • Evil Counterpart: Dark Samus is an obvious one, but even the original Metroid Prime had similarities to Samus. Both wore mechanical suits with similar abilities (the beam weapons, missiles, the tractor beam attack similar to the grapple beam) and a blue 'true form' under it (the Essence for Metroid Prime and the Zero Suit for Samus).
  • Evil Knockoff: Though unlike the SA-X from Fusion, Dark Samus isn't quite as much of a carbon copy, seeing as it used to be a Metroid and has several distinct abilities.
    • Expy: Of SA-X. Although Retro declared more influence from the "mirror boss battle" in Zero Mission. That said, Fusion was in development before Prime, and they were handled by different teams, so it's a bit nebulous which is the Expy of which.
  • Eviler Than Thou: Even though she initially helps the Warrior Ing attack Samus, some of the space pirates she is seen fighting with over some Phazon were Ing possessed, suggesting one of them went back on any possible deals that could have been made. Since Ing don't make much use of the phazon they already have, it can be assumed they were simply trying to halter Dark Samus. She then takes control of the source of Phazon in Corruption!
  • Eyes Do Not Belong There: If one pays attention, they will notice her final form in Echoes has eyes on the back of her hands!
  • Flight: A consistent ability she keeps after developing that Samus doesn't really have, though at points she can only hover over the ground.
  • From a Single Cell: Or single Phazon particle... It takes destroying every bit of phazon in the universe to finally kill her.
  • From Nobody to Nightmare: As Metroid Prime she had some major significance, yes; but in the grand scheme of things she was the byproduct of just a random Leviathan. And then Dark Samus would go on devising a way to become the very mind of Phaaze itself...
  • Galactic Conqueror: She tries her best in Corruption.
  • Hero Killer: Not only does she terrify the prophetic Chozo, tear through the pirates, casually dispatch Ing, break Luminoth technology and take over two planets but she also takes down four named characters in Corruption.
  • Hoist By Her Own Petard: Subverted all three times. She can't necessarily help being majorly composed of the thing to defeat her with, can she?
  • Homing Projectile: The particle wave generator, stolen from the pirates, makes these. Also the core form in Prime Pinball could shoot some from her tentacles.
  • Humanoid Abomination: She started out as a Metroid heavily mutated by prolonged exposure to Phazon before being destabilized and exploding. Absorbing Samus' Phazon Suit enabled her to reform as a black, biomechanical doppelgänger of Samus bent on spreading Phazon throughout the universe and even other dimensions, and she was unkillable as long as Phazon existed.
  • Implacable Woman: Best displayed after beating her at the end of Metroid Prime 2, where she uses the last of her strength to crawl and attempt to grab Samus one last time. Similar to another Implacable Man. Then she returns in Metroid Prime 3 more dangerous than ever.
  • Invisibility: She tries a few different forms of it, the counter Samus's constantly updating methods of tracking.
  • Joker Immunity: She can reform herself from phazon particles. You destroy her for good in Prime 3, though.
  • Laser Cutter: Her version of the charge beam. Rather than draw energy for a larger blast, she shoots a continuous blast and sweeps with it.
  • Laughing Mad: Dark Samus often laughs rather maniacally in some of her appearances in Metroid Prime 2 Echoes. For a "woman" her voice is pretty deep.
    • By Prime 3, it's ascended to one of her main forms of "battle dialogue".
  • Load-Bearing Boss: In the first and third games. As Metroid Prime, her defeat made the Impact Crater presumably cave in on herself. In Corruption, her death makes Phaaze die because she merged with the device she was using to control it, one assumes. Averted in Echoes, because the Load-Bearing Boss had already been killed.
  • Made of Phlebotinum: Dark Samus made of Phazon.
    • Though that depends on to what extent you consider Phazon to be sentient/separate beings or just a substance.
    • And, somewhat more literally than the trope above it suggests, as the Chozo once referred to her only as "The Worm."
  • Mega Manning: First some space pirate armor and weapons, then the phazon suit, and finally she acquires the abilities of other Hunters besides Samus during the events of Metroid Prime 3 Corruption.
  • Mind Control: Does a whole lot of it later.
  • Mook Maker: As the Metroid Prime she was a Metroid maker.
  • Pet the Dog: Despite her psychopathic nature, she actually shows some degree of compassion towards Metroids held captive by the Space Pirates in the second game. This makes sense because she is a Metroid.
  • Phlebotinum Dependence \ Phlebotinum Muncher: Her very introduction in Echoes involves eating some Phazon. Then the addiction gets bigger the more she eats.
  • Pistol-Whipping: It is not entirely clear if her cannon makes contact, but she has a striking move she'll use on players who don't keep their distance as well as to stop their missiles, forcing them to wait for an opening if they are determined to hit her with them.
  • Poisonous Person: Heavily infused with phazon but beyond that, she used to have missiles that left behind damaging green clouds. Green being a video game shorthand for "poison".
  • Powered Armor: As Metroid Prime she was covered in an exoskeleton of assimilated Space Pirate technote  As Dark Samus she was clad in a biomechanical version of Samus' armor.
  • Recurring Boss: Throughout the trilogy
  • Red Baron: She is referred to by the Space Pirates as the Dark Hunter. After she took over, they take to calling her the Dark One, and the Black Demon. note 
  • Sanity Slippage: Inverted: She starts out as being completely insane in Metroid Prime 2 Echoes. By the time of Metroid Prime 3 Corruption, however, she has become sane enough to make complex plans that ensure that she succeeds, although she does retain a high degree of instabilitiy.
  • Shadow Archetype: To Samus, obviously, but given the series continuity, this is partly retroactive. In Fusion, Samus talks about how the SA-X must be stopped before it ever realizes its potential and becomes a threat to the galaxy, which is exactly what we see Dark Samus do. The kicker is that by becoming part Metroid, she is even more like Dark Samus, despite having an opposite motivation, and is fighting what functionally might as well be her old self, since it has most of her old abilities.
  • Short Range Shot Gun: Cruelly averted, she has a scatter shot version of the power beam fans call the "shrapnel beam". It's about as easy to dodge as it sounds (not at all without cover).
  • Wave Motion Gun: The armored form of Metroid Prime has one whose color depends on the current barrier, and both forms of Metroid Prime in Metroid Prime Pinball regularly let off powerful shots that can quickly kill you.
  • Wrong Genre Savvy: Despite her name and her comfort in its atmosphere, Dark Samus is not from Dark Aether, nor is she a Darkling. Meaning the Light Beam is worthless against her, but the Dark Beam is devastating.
  • You Will Not Evade Me: Formerly, with a "snare beam".


"Without warning, our doom fell from the sky. From whence it came we do not know. The horror shrieked its name: GOREA. Gorea is power beyond reckoning and evil unrelenting. The universe has not known terror such as this. At first we thought Gorea was a comet. It crashed upon our planet and emerged as a vapour, it mimicked our cellular structure and replicated itself in solid form. We have seen Gorea alter its atomic structure between polarizing states. Our scientists believe it may also possess other SHAPE-CHANGING abilities. We deployed our deadliest weapons to defeat the beast. To our horror, every weapon was somehow used against us. The war only lasted a few standard galactic months. Even with the galaxy's most powerful technology at our disposal, we fell like dry grass beneath the blade. For Gorea was immune to even our most sophisticated weaponry, while we were defenseless against its relentless attacks. It devoured our people's life energy and grew even more powerful from such sustenance. Death swept across our worlds, and we despaired. We feared not only for the extinction of our race and our galaxy, but the possibility that the evil would sweep across the entire universe, annihilating all in its path. We gave our lives to confine the foul monstrosity known as Gorea. Do not seek this creature unless you have the means to DESTROY it."
The Alimbic Order of Elders


  • Alien Geometries: It can throw rocks through walls and through floors while leaving them intact.
  • Barrier Change Boss: For most of the first phase.
  • Batman Gambit: It sent the distress signal to all of the Hunters in the galaxy so that they would find the Octoliths and set it free. It even managed to get Hunters with weapons equivalent to the now gone Alimbics, to make assimilating them that much easier.
  • Big Bad: Of Hunters.
  • Combat Tentacles: Either this or a Tractor Beam, depending on how you interpret it. Either way, Gorea can drain Life Energy with them and assimilate weapon systems this way. Can't get Samus's power beam, which unfortunately won't do any meaningful damage anyway.
  • Curbstomp Battle: The fight between it and the other antagonists of the game sees Gorea win pretty easily, the other antagonists being all six of the other hunters at once.
  • Despair Event Horizon: The survivors of its initial assault were said to seem lifeless, even if they weren't injured.
  • Dishing Out Dirt: Its second phase does this.
  • Eldritch Abomination/Humanoid Abomination: Was originally the former, but became the latter after stealing that form from the Alimbics. It degenerates a little as you fight it, though.
  • Get Back Here Boss: The only way to defeat its final phase is to let it run, track it down and then repeat the process. It will immediately appear when you can't hurt it but as soon as you can it will vanish before any damage can be done, forcing you to find it the hard way.
  • Guide Dang It: How to unlock its final phase. More specifically, you have to shoot a number of colored panels on the walls of its arena in a certain order with the proper weapons corresponding to the color of the panel. This is actually hinted at in several of the logbook scans, but it's so vague that most people needed a guide to figure it out anyway.
  • Improvised Weapon: It likes throwing the frozen colonies of cyanobacteria that float around in its prison.
  • Mega Manning: Its first phase sees it steal and use weaponry. Oh, and most of the weapons it employs are much more dangerous when in Gorea's possession, except possibly the shock coil. Also, it ends up using the seal sphere meant to seal off its powers as a battery to siphon energy off of and continue on with.
  • Only a Flesh Wound: Blowing off its arms doesn't bother it much in fact, the limbs are the only thing Samus's weapons can damage. The final stage is against a flying torso! If you're not quick, it will grow its arms back too.
    • Cognizant Limbs While Hunters has no lock-on feature, Gorea's arms have their own health bars. As does the seal sphere.
  • Raymanian Limbs: Its head, much like Trace
  • Sealed Evil in a Can: Apparently no one thought to gag it though, since it can still talk or otherwise send messages.
  • Soiled City on a Hill: The Alimbics got invaded by aliens. They built a lot of weapons, chased out the aliens, declared themselves invincible, and told everyone to stay away. Gorea then came and wrecked everything.
  • Starfish Alien: Don't let that picture fool you.
  • Suicidal Overconfidence: Not really, which makes it more annoying once it truly realizes something can hurt it.
  • Telepathy: How it communicates.
  • Verbal Tic Name: The Alimbics call it the first thing it said.
  • Villain Teleportation: Once you unlock its final stage.
