Zebes Shin'nyuu Shirei
Metroid=Mutant
- Arch-Enemy: It regards itself as Samus's nemesis.
- Canon Foreigner: It has only appeared in Zebes Invasion Order, a game book based on the first Metroid.
- Extra Eyes: It has at least four eyeballs in its membrane.
- Final Boss: In the bad ending, the M=M is fought as the final boss in the pirate ship's docking bay.
- Not Quite Dead: This trope comes into effect in multiple scenarios. Samus sends it out the airlock of her escape ship, only for it to board the Space Pirates' ship. If Samus defeats the M=M herself in the docking bay, it survives and latches onto her escape ship. In the pirate ship's control room, it appears to be defeated, only to rise up again and attack the Pirate Boss. Even being aboard the pirate ship when it's blown up by a large missile isn't enough to kill it, since the epilogue implies that it survives even in the vacuum of space.
- Removed Achilles' Heel: It is resistant to the Ice Beam, although its internal organs are still vulnerable.
- Starfish Aliens: It looks like a giant jellyfish with multiple eyeballs in its membrane and large crustacean-like claws.
- Super-Persistent Predator: Compared to all other Metroids, this one goes to great lengths to hunt down and kill Samus, even regarding itself as her nemesis. Even in the epilogue of the Golden Ending, it's still hunting her.
- Xenomorph Xerox: Not so much in terms of appearance, but its role in the book as a Super-Persistent Predator stalking the heroine aboard a spaceship definitely calls the original Xenomorph to mind. There's even a sequence where it sneaks aboard Samus's escape pod and she forces it out the open airlock, just like in the original Alien.
Pirate Boss
- Canon Foreigner: He only appeared in Zebes Invasion Order, a game book based on the first Metroid.
- Crouching Moron, Hidden Badass: Samus does not consider him particularly clever, and yet his zeal is so great that he is able to best a Cyborg in a sword duel.
- Good Smoking, Evil Smoking: In the midst of a destroyed command room littered with corpses, he is found casually sitting down and smoking a cigarette.
- Early-Installment Weirdness: This early game book is the only instance of a human Space Pirate. All later installments in the series would depict only aliens among their ranks.
- Enemy Mine: Depending on Samus's choices, the Pirate Boss may team up with Samus to take down the Metroid=Mutant, even returning her confiscated Ice Beam.
- Final Boss: Functions as this for the game book, if the reader is going for the Golden Ending.
- I Was Beaten by a Girl: He is left in disbelief when he learns that the Space Pirates on Zebes were defeated by a woman. During his final duel, he expresses disappointment that he fatigues himself while fighting a woman; ironically, if he says this line, he then proceeds to kill Samus.
- No Name Given: He was only called the "Pirate Boss".
- Noble Demon: When Samus confronts him for the Metroid capsule, he honorably lends her a sword to challenge him in a sword duel.
- One-Hit Kill: If he confronts Samus and the Metroid=Mutant in the docking bay, he shoots Samus with a large caliber beam cannon. This is an automatic game over.
- Powered Armor: If he confronts Samus and the Metroid=Mutant in the docking bay, he appears wearing a powered suit.
- Smarter Than You Look: Samus calls him dimwitted and not clever, but then concedes that he must be smarter than he looks when she realizes that he let her fight the Metroid=Mutant for him.
Nintendo Comics System
"Big Time" Brannigan
Debut: Deceit Du Jour
"I'm a bounty hunter, Mother Brain - that means I'm one mean mercenary."
A Bounty Hunter hired by Mother Brain to capture an intruder, who turns out to be Samus Aran.- Always Someone Better: Samus Aran is the only one standing in the way of Big Time being the undisputed greatest bounty hunter. It's a sore spot for Big Time, who nearly shoots a Zoomer for mentioning it.
- Amplified Animal Aptitude: Big Time appears to be a sapient Dessgeega, which are normally depicted as feral wildlife.
- Armless Biped: Big Time only has two limbs, and he is usually holding his gun with one foot.
- Bounty Hunter: A rare, more traditional example of this trope in the Metroid series. Mother Brain puts a price on the intruder's head, and Big Time goes to hunt down the intruder and get paid for it.
- Canon Foreigner: Only appears in the Nintendo Comics System.
- Powered Armor: Big Time wears a Bounty Hunter Suit, very similar to Samus's Power Suit.
- Red Baron: Brannigan seems to be his real name, but most people call him by his nickname "Big Time".
- Spikes of Villainy: Unlike Samus's Power Suit, Big Time's suit has multiple spikes sticking out of the arms, just like a Dessgeega.
- Villain Ball: Having turned in Samus to Mother Brain, Big Time successfully completed his mission and was ready to be paid. However, due to his pride, he could not resist the temptation of shooting Samus and eliminating the better bounty hunter, which caused the gun he was holding to explode. As a result, Samus was able to escape, and Big Time loses his reputation and his life.
- We Used to Be Friends: The bantering dialogue between Big Time and Samus suggests that they used to be old friends, or at least friendly rivals, before Mother Brain hired Big Time to take down Samus.
- You Have Failed Me: After Big Time accidentally lets Samus escape, Mother Brain sends him to be eaten by Metroids.
Captain Dare
Debut:Breakout
A Galactic Federation Police Officer who arrests Princess Lana and Samus Aran, wrongly believing them to be criminals.
- Canon Foreigner: Only appears in the Nintendo Comics System.
- Inspector Javert: He ruthlessly apprehends Lana, believing her to be responsible for a long list of crimes... which were actually committed by Mother Brain.
Judge Racklas
Debut: Breakout
A Galactic Federation Federal Judge and a fellow member of Ridley's species. During Mother Brain's plot to arrest Princess Lana, he is kidnapped and replaced by Ridley.
- Canon Foreigner: Only appears in the Nintendo Comics System.
- Distressed Dude: The real Judge Racklas is tied up with rope and held prisoner on Metroid, until he is rescued off-screen by Kevin Keene.
- First Day from Hell: Racklas is only a new Federal Judge when he gets captured by Space Pirates.
- Impersonation-Exclusive Character: Racklas briefly appears in one panel while completely bound with rope and does not have any dialogue, while the rest of the comic features Ridley impersonating him. Therefore, most of what we know about Racklas comes from the Galactic Federation, Princess Lana, and Mother Brain discussing the disguised Ridley.
- Inexplicably Identical Individuals: Mother Brain mentions that all members of his race look alike, which is why the Galactic Federation was easily fooled by Ridley's disguise.
- Lamprey Mouth: Due to being based upon Ridley's original artwork from Metroid, Racklas has an odd alien design with a tube-shaped mouth.
- My Species Doth Protest Too Much: Unlike all other known members of his species (such as Ridley and Greed), Racklas is not a Space Pirate or a criminal. Instead, he is a trusted honorable judge of the Galactic Federation.
- Small Role, Big Impact: Judge Racklas himself only appears for a single panel in the comic and doesn't even have any dialogue. However, his kidnapping is what kickstarts the plot of Breakout, since Ridley is able to sentence both Lana and Samus to prison. The plot is only fully resolved when Racklas is rescued off-screen by Kevin.
Super Metroid
Armstrong Houston
Debut: Super Metroid (comic)
A Bounty Hunter known to work with Samus.
- Blue Is Heroic: Wears a Blue Power Suit and is one of Samus' allies.

- The Cavalry: Houston shows up to save Samus after she's pinned down by Space Pirates during the first battle on Zebes.
- Changed My Mind, Kid: Houston comes back to rescue Samus when she's pinned down by the Space Pirates, after she had previously accused him of only wanting to go to Zebes for bounties and nothing else.
- Differently Dressed Duplicates: Houston has a near-exact (if not the same) power suit as Samus, and even has an identical ship - except all of his gear is blue instead of her orange-yellow motif. However it is noted Houston's gear is significantly less effective then the real deal.
- Hero-Worshipper: At several points in the comic, Houston asks Samus to let him become her partner. Samus turns him down, but does admit that he has helped, and that now they are even for the time she saved his life in an asteroid belt. His armor is also a copy of Samus', though it is less sophisticated.
- Mythology Gag: One of the multiplayer color schemes in Metroid Prime 2: Echoes resembles Houston's armor.
Samus and Joey
Joey Apronika
Debut: Metroid: Samus and Joey
A boy from the frontier planet of Liberty, who wants to protect people like his father. After Samus saves Liberty from Space Pirates, Joey asks her to take him on as her disciple as she travels the stars. Initially Samus just plans to drop him off at a spaceport and let him make his own way from there, but over time he manages to prove his worth and Samus even grows a little fond of the kid.
- Ancestral Weapon: The Field Knuckle, which was originally his father's weapon.
- Attack Reflector: Near the end of the manga he masters the Field Knuckle's ultimate technique, Exodus, which allows him to absorb attacks and fire them back as an Energy Ball.

- Hero-Worshipper: Considers Samus to be the coolest person ever.
- Kid Samurai: Doesn't have a lot of fighting experience at the start of the manga, but does have spunk.
- Kid Sidekick: To Samus in Samus and Joey.
- Like a Son to Me: Implied in the final chapter of Samus and Joey - before Samus heads off to face her destiny she hugs Joey, claims to fight for all the children of the galaxy as if they were her own, and tells him to "grow into a strong, kind man".
- Made of Iron: Joey first earns Samus's respect by telling her not to worry about catching him in the shockwave of her Super Missiles, promising he'll tough it out. Taken further when he receives the Field Knuckle.
- Psychoactive Powers: The strength of his Field Knuckle is proportionate to the user's will, and falters when his heart is shaken.
- Rocket Punch: In the Distant Epilogue an adult Joey has become capable of firing fist-shaped energy blasts with his punches.
- Stone Wall: Has defensive abilities surpassing Samus, but not much else.
- Supporting Protagonist: Samus and Joey is told from his perspective, but Samus is undoubtedly the hero of the story.
- Support Party Member: His power and agility are no match for Samus, but his barriers are incredibly tough and can cover a wide area, which is useful when an enemy targets civilians or isn't giving Samus many openings to attack.
Galactic Federation
Dr. Diana Apronika

Craftsmen
In General
Debut: Metroid: Samus and Joey
Hey! Hey-hey! Ho-hey! If pushin' won't do, then try pullin' too! Don't let machines get tough for you! They all begin with just one screw!
A race of small but brilliant engineers and machinists. Once famous throughout the galaxy, they retreated to the jungle planet of Jatsuk after growing tired of seeing their creations used for evil.
- Bizarre Alien Limbs: Craftsmen have the body plan of an upright hamster but with the addition of two long tentacles sprouting from their shoulders, which serve as their primary manipulators. This looks even stranger while they're riding their hover platforms, which disguise the shape of their lower bodies.
- Canon Foreigner: Appear only in the manga Metroid: Samus and Joey.
- Cool Chair: While working, they often ride around in hover platforms to compensate for their small size.
- Living MacGuffin: Blast threatens to destroy their planet unless they agree to build weapons for the Greed Corps.
- Not So Similar: Their status as a once famous and advanced race that went into seclusion makes them seem like engineer counterparts to the Chozo's Proud Warrior Race days. However, they aren't quite as devoted to their vows as the Chozo are, as proven when they assist Diesel in modifying Blast's bomb, and later show up in a cloaked warship to fight alongside the Galactic Federation.
- The Spark of Genius: Capable of understanding the structure and purpose of an object just by touching it, and seem to have a compulsive desire to take things apart and see how they work.
- Weird Beard: Most Craftsmen are depicted with a "moustache" covering their mouth, composed of either fur or small tentacles.
Diesel
Samus' mechanic, who runs the salvage shop "Junk Quixote". He refused to move to Jatsuk with the rest of his race, believing that he could still use his abilities to make people happy. Spends most of Metroid: Samus and Joey acting as Joey's unofficial guardian, and tagging along whenever he joins Samus on a mission.
- Cool Chair: Unlike the other members of his race, he is never seen outside of his hover platform.
- Electronic Eye: Lost his left eye in an accident, which was replaced by a monocle-like prosthetic created by Papa Lightning.
- Fighter, Mage, Thief: The thief to Joey's fighter and Samus' mage.
- Hidden Depths: The fourth chapter of the Metroid EX arc reveals the rest of Diesel's race and his pariah status among them.
- Mistook the Dominant Lifeform: When Joey first sees Diesel, he mistakes him for Diesel's pet.
- Snarky Non-Human Sidekick: Downplayed - he's the snarkiest member of Samus and Joey's main cast, and certainly looks the part, but he doesn't usually act this way unless provoked.
- Transforming Vehicle: His personal ship, the Junk Hawk, can retract its wings and deploy tank treads for land-based travel.
- Utility Party Member: Isn't much of a fighter compared to Samus or even Joey, but is skilled with technology. When Samus is absent, Joey also relies on him for transportation.
- Waddling Head: Has a shorter, rounder body than most of his race, and his hover platform makes him appear even more stubby.
"Papa" Lightning
A Craftsman elder with hair resembling a bolt of lightning.
- The Mentor: To Diesel.
- Respected by the Respected: In the finale Lightning shows up alongside a Galactic Federation armada to attack the Greed Corps base, with the fleet admiral saluting nervously and calling him "sir". When another officer reacts with confusion, he merely explains that Lightning is "someone very important".

—Samus and Joey chapter 15
- Arms Dealer: They seek to obtain Chozo Technology and use it to create weapons to sell.
- Canon Foreigner: This organization, its members and associated characters only appeared in Samus and Joey and Metroid EX.
- War for Fun and Profit: Samus even says they sell war and, in Metroid EX, they provide technology for the Greed Corps, seeking to benefit from the atrocities that will ensue.
"U-Ton"
Debut: Metroid: Samus and Joey
A timid robot(?) of the model "U-Tristam Delta III", saved by Joey from some bullies and nicknamed "U-Ton". The two soon become the best of friends, spending most of the day hanging out together. Unfortunately, U-Ton is actually a defective combat bioroid that went berserk and destroyed its manufacturers' transport vessel before it could be decommissioned - one which Samus has been hired to destroy at all costs.
- Artificial Human: While it's not immediately obvious, U-Ton was created from a mixture of living and mechanical components, and even has a humanlike face hidden beneath his helmet.
- Call-Back: Samus later discovers weapons similar to the Delta III being manufactured by the Dominion, and deduces that U-Ton was also one of their creations.
- Chest Blaster: The mouthlike structure on its stomach can open to reveal a hidden cannon.
- Death by Newbery Medal: The death of his friend shakes the young Joey greatly, as does the knowledge that his hesitance to pull the trigger could have doomed everyone else he cared about.
- Doppelgänger Attack: Its "Delta Mirage" system allows it to project images of itself to confuse enemies.
- Extendable Arms: Tipped with retractable claws.
- Fishbowl Helmet: His "head" is revealed as one when it's destroyed, revealing a human-like head underneath.

- Killer Robot: Not entirely robotic, but close enough.
- Robot Buddy: To Joey, even if technically he's a Bioroid Buddy.
- Shoot the Dog: Samus is forced to kill U-Ton before he hurts anyone else, causing Joey much grief.Diesel: "Do righteous heroes only fight those enemies they want to defeat? No, sir! It's hard for Samus to pull the trigger, but now there's no choice. Now there's bystanders. 'til now the weight of it has been like a mountain, but even so, that trigger will be pulled. That's who Samus Aran is."
- Suicide Attack: As a last resort, the Delta III is capable of overloading its onboard nuclear reactor to create a massive explosion.
- Tragic Monster: U-Ton has no control over himself while berserk. Even while Diesel agrees that the bioroid must be destroyed, he also says it can't be blamed for trying to escape and preserve its own life.
- Why Am I Ticking?: As U-Ton loses control of himself and starts attacking people, things go From Bad to Worse with the revelation that he's also started warming up his nuclear Self-Destruct Mechanism.
Project Ultimate Warrior
Debut: Metroid: Samus and Joey
In General
- Evil Knockoff: The Ultimate Warrior project aims to replicate the technology in Samus's Power Suit.
Dangelo
There's hundreds of guys...with grudges against you.
An escaped convict with a grudge against Samus, whom the Dominion provide with a replica Power Suit and a cloaking device in order to frame her for crimes.
- Brought Down to Badass: He attempts this on Samus helpless by forcing her to fight with a broken Arm Cannon. She just beats him up with her bare hands instead.

- Canon Foreigner: He only appeared in Samus and Joey.

- Nested Mouths: The lower part of his suit's helmet can split open, resembling a mouth.
- Punched Across the Room: Samus defeats Dangelo by punching him so hard that it both shatters his helmet and sends him flying through a wall... after which his unconscious body falls several storeys and hits a car so hard that it explodes.
- Weapon of X-Slaying: His suit's cloaking device was custom-designed to foil detection by Samus's Thermal and X-Ray Visors.
Desert Phantom
I changed my mind, you have five minutes to run.
A mass-produced "hunter-killer" Cyborg designed for desert combat, created by combining a spider-like organism with a humanoid torso.
- Arm Cannon: Its left arm ends in a Gatling gun.
- Blade Below the Shoulder: Its right arm ends in a lance.
- Cyborg: The spider component was originally alive, though it's been heavily remodelled.
- Gatling Good: Its Arm Cannon isn't an energy weapon like Samus's, but a Gatling gun firing live ammo. Unlike Dangelo's it's not really disguised. According to the volume notes it was designed this way to prevent overheating.
- Spider Tank: With the rear legs replaced by a pair of caterpillar treads. According to the volume notes, the lower half was created from an actual alien arachnid.
Samus Tank
A piloted, hovering vehicle derived from the Desert Phantom's schematics.
- Awesome, but Impractical: Described in the volume notes as a vanity project that isn't suitable for mass production.
- Cool Chair: While armed, its creator seems to treat it mostly as a comfortable place from which to observe his hunter-killers in action.
- Grenade Launcher: Its "tail" stores a single-shot plasma grenade, which detonates to rain Beam Spam on enemies.
- Hover Tank: Hovers above the ground, and is equipped with light machine guns and a single-shot Grenade Launcher.
- Spider Tank: Despite hovering above the ground it has eight stubby legs, and is implied to still use a spider-like organism as its core.
Integra
This is the ultimate soldier, the definition of perfection!
(Mass-production type)
The final phase of the Ultimate Warrior project, a "complete body integration" of Samus' technology into a combat bioroid. Claimed to boast 500 times the power of the test units before it.
- Anti-Infantry: The head features a pair of Gundam-style antipersonnel machine guns.
- Beam-O-War: Samus attempts this against the Integra, only to be blasted away.
- Belly Mouth: In addition to its Samus-style helmet it has a face on its chest, presumably belonging to its organic components. It's less obvious in the mass-production version, where the mouth's design is simplified and appears to be simply a seam in its armour.
- Cyborg: Described as about 80% mechanical, 20% organic.
- Degraded Boss: After the prototype is destroyed, Samus encounters mass-produced variants, first when she goes further into the facility and later at the Galactic Ruins.
- Evil Knockoff: Based on data gathered from Samus's suit, the Dominion built the Integra to surpass it in every way... only to be shocked when Samus taps into her Heroic Spirit and her suit's energy readings rise far beyond anything recorded.
- Grenade Launcher: In addition to beams, its destroyer arms are capable of firing replicas of Samus's Power Bombs. Rapid-firing them.
- Multi-Armed and Dangerous: Its main arms end in claws, while a pair of secondary "destroyer arms" end in Arm Cannons.
- Super Prototype: The mass-production model is simpler in design than the prototype and far less powerful, but still considered an excellent combat unit.
- Super-Toughness: Capable of tanking Samus's charged Plasma Beam without a scratch.
- Vibroweapon: Is described as having vibroblades built into its main arms (presumably its claws).
Dominion Agent
Greed Corps
Greed
Debut: Metroid: Samus and Joey
Another member of Ridley's species, who leads the self-named Greed Corps.
- Ambiguously Related: His name follows the same theme as Jealousy, a minor antagonist from chapter 5, who may or may not be a member of the same species as his general Bishop.
- Backup Twin: Another cruel Space Pirate leader from the same species as Ridley (implied to be finally deceased after the events of Super Metroid). Samus initially mistakes Greed for Ridley, though his build is slightly heavier and his personality has a few differences.
- Big Bad: Of the final arc of Samus and Joey, "Metroid EX".
- Black Cloak: Introduced as a humanoid figure in a cloak, before shedding it to reveal his (much larger) true form.
- Canon Foreigner: Appears only in Metroid: Samus and Joey.
- Fat Bastard: While it's not obvious, he might be an example of this by the standards of his species. A Flashback to Ridley depicts him as almost skeletal compared to Greed and with more defined muscles, implying that either Greed is this or Ridley is Lean and Mean.
- Non-Action Big Bad: Despite his implied combat strength Greed never directly attacks or harms anyone, even when his enemies are helpless before him. This is one of the traits which distinguishes him from Ridley.
- Orcus on His Throne: Big Bad of the final arc, but after his introduction he immediately flies back to his base and doesn't appear again until Samus travels to him.
- Revenge: Targets Samus to avenge the death of Ridley. Not so much because he liked Ridley, but because his death was a blow to the status of their race.
- Self-Disposing Villain: Dies when he is unable to control the Animus and is consumed by its power.
Body Snatcher
Debut: Metroid: Samus and Joey
Member of a species with the ability to possess others, who serve the Greed Corps and/or the Dominion.

Debut: Metroid EX: Samus and Joey
- Canon Foreigner: Their only appearance is in the final arc of Metroid: Samus and Joey.
- Power Parasite: Each of the Six Stars wields one or more abilities stolen from Samus's Power Suit, often enhanced beyond its original strength. Samus can regain these abilities by defeating them.
Zameel
Wielder of the Missile and Super Missile abilities, who terrorises the town of Brigandia on planet Outlaw.
- Arm Cannon: Launches missiles from holes in his palms
- Hoist by His Own Petard: Lacking most of her weapons, Samus struggles to inflict damage on Zameel... until he switches from regular Missiles to Super Missiles, which are slow enough that she can catch one and throw it back at him.
- Macross Missile Massacre: His primary means of attack.
- Nasal Weapon: Launches Super Missiles from his nose.
- Pig Man: Resembles a pig.
- Significant Anagram: ザミイル (Zameel) to ミサイル (Missile).
- Trigger-Happy: Has poor control over his Missiles, often firing them involuntarily or hitting his own Mooks.
Golon
Wielder of the Morph Ball and Screw Attack abilities, and the eccentric ruler of planet Maru.
- Ability Mixing: Combines the Morph Ball and Screw Attack into a single attack form not possessed by their original owner.
- Be the Ball: His Morph Ball ability; it's significantly larger than Samus's and retains his face.
- Bouncing Battler: His fighting style with the Morph Ball ability active.
- The Caligula: Under Golon's rule, being insufficiently round is punishable by death (or rather, being forcibly installed into one of his robot soldiers).
- Frog Men: Similar in appearance to a toad, including an extending tongue.
- Logical Weakness: While rolling at enemies, he deflects all attacks... except attacks from the side aimed at his centre of rotation.
- Rolling Attack: An incredibly deadly one once he reveals his second ability.Samus: Never touch the Screw Attack! Anything that does is destroyed!
- Shout-Out: His name, appearance and rolling abilities make him heavily resemble a Goron.
Chrysta
Wielder of the Ice Beam ability, an "electrical lifeform" fused into a Greed Corps mining facility at the heart of a frozen star.
- Anticlimax Boss: Samus uses the Screw Attack to kill Chrysta in a single blow; the greater challenge is escaping alive as the star begins to re-ignite.
- Evil Cannot Comprehend Good: Chrysta is correct that Samus is incapable of piloting her damaged ship out of the star before it re-ignites... but it fails to take into account her companions Joey and Diesel, who with the help of Samus's reclaimed Ice Beam are capable of holding the ship together long enough to escape.
- Freeze Ray: Capable of firing Ice Beams to defend itself.
- Meaningful Name: Its name is derived from "Crystal".
- Reactor Boss: Chrysta's supercharged Ice Beam is the only thing stopping the star from thawing out with Samus's ship still inside. It points this out, and claims that Samus has no way to win without dying in the process.
- Tim Taylor Technology: Its facility is capable of boosting the power of Samus's Ice Beam enough to freeze an entire star.
Blast
Wielder of the Bomb and Power Bomb abilities, who uses a "Super Power Bomb" to hold planet Jatsuk to ransom.
- Dirty Coward: When he realises Samus is stuck on Jatsuk he abandons his ransom scheme, simply fleeing back to space and waiting for his Power Bomb to explode and kill her."Ahahaha! I'm not foolish enough to fight you and risk being attacked myself. Sit back and win, that's my motto!"
- Earth-Shattering Kaboom: Attempts this on Planet Jatsuk.
- Hoist by His Own Petard: Defeated when the inhabitants of Jatsuk remodel part of his Super Power Bomb into a thruster, allowing Samus to ride it into his ship.
- Tim Taylor Technology: Capable of constructing a giant version of Samus's Power Bombs powerful enough to destroy a planet.
Rockets
Wielder of the Speed Booster ability, the sponsor and reigning champion of the underground "Death Race Firecracker".
- Ace Pilot: Has a reputation as the fastest in the galaxy.
- Superhero Sobriquets: Known as "Lightning Rockets".
- Trap Is the Only Option: The poster for the Death Race featured Rockets wearing the symbol of the Greed Corps and holding up the Speed Booster ability orb, making it an obvious call-out to Samus.
- Wacky Racing: The Death Race markets itself as a gathering of the worst villains in the galaxy, and appears to have no rules whatsoever.
Defen
Wielder of the Varia Suit ability, responsible for turning a planet's ocean into acid.
- Deus ex Machina: Samus is only able to defeat Defen by chancing upon an underwater volcano and triggering an eruption in his face.
- Hostile Terraforming: His Rastodon converts its environment into acid.
- Kraken and Leviathan: His pet the Rastodon.
- Lizard Folk: Resembles an armoured humanoid chameleon.
- Meaningful Name: Shortened from "Defence".
- No MacGuffin, No Winner: The explosion that defeats Defen also causes the Varia Suit orb to be blasted away, leaving Samus unable to reclaim it. It's later revealed to have been salvaged by Bishop.
- No-Sell: Defen's Varia Suit ability allows him to ignore the effects of the acid sea, while his Rastodon is native to that environment. Thanks to the Varia Suit's defences, Samus's beam weapons are also unable to injure him.
- Power Nullifier: Not only does the acid ocean slowly dissolve Samus's suit, it also destroys physical projectiles and prevents her from moving fast enough to use the Screw Attack.
Bishop
Debut: Metroid EX: Samus and Joey
The Greed Corps's "General of Wisdom".
- Canon Foreigner: Appeared only in Metroid EX
- Chess Motifs: The source of his and Knight's Theme Naming.
- Creepily Long Arms: Clawed ones resembling sheets of cloth, which he normally keeps wrapped around his body.
- Expy: Bishop's pauldroned robe, his use of powerful offensive/defensive hands, and his true face being hidden in plain sight on his host's forehead call to mind Myst-Vearn from Dragon Quest: The Adventure of Dai. His personality, however, is closer to Myst's colleague Zaboera.
- Half the Man He Used to Be: Cut in two by Knight's "Soul Impact", only to reveal that Knight missed his real body.
- Master of All: Boasts that his combination of the Plasma Beam and Varia Suit orbs grants him both the ultimate attack and the ultimate defence.
- Oculothorax: His true body appears to have this structure, from what we can see of it.
- Opportunistic Bastard: On learning of the "power of the gods" that Greed had set his sights on, Bishop planned to depose his boss and steal it for himself.

- Puppeteer Parasite: His true body is the "third eye" in his forehead.
- The Resenter: Resents having to work alongside his fellow general Knight - partly out of disgust at Knight's sense of honour, but mostly out of fear that Greed has started favouring Knight over him.Bishop: "Master Greed, does sending me alone make you... uneasy?"
- Rise from Your Grave: Has an army of zombies burst from the ground to attack Samus, including those of the Deadly Six Stars (even fusing them together into a giant monster). Subverted in that they're actually just robots.
- Special Odd Hand: Each of his hands has one of Samus's ability orbs embedded in it. His left hand with the Varia Suit orb is "an impregnable shield", while his "invincible right hand" can fire devastating Plasma Beams.
- Third Eye: Has a cyclopean face embedded in his forehead, which evokes this look while its mouth is closed.
Knight
Debut: Metroid EX: Samus and Joey
A human member of the Greed Corps, referred to as the "General of Strength".
- Always Second Best: Claims to have been this to his sparring partner Rand, due to Rand's ability to reflect his powerful attacks back at him.
- Black Knight: While he doesn't wear much actual black, his title of "Knight" is a very fitting one.
- Calling Your Attacks: His sword techniques "Guillotine Blast", "Void Meteor Return", "Explosive Divide" and "Soul Impact".
- Canon Foreigner: Only appears in Metroid EX.

- Establishing Character Moment: Makes his entrance by one-shotting the "zombies" his own ally was using to attack Samus (calling them desecration of the dead), instead challenging Samus to a one-on-one duel. He then shields her allies from an explosion simply because he wasn't ordered not to.
- Faster Than They Look: Samus is shocked to learn that someone so huge and heavily-armoured is fast as well.
- Glowing Eyes of Doom: Prone to doing this when he gets serious.
- Master Swordsman: To the extent where even Samus with 5 of her 7 abilities restored has trouble keeping up with him. She wonders aloud about where the hell Greed even found a guy that strong.
- Parrying Bullets: Capable of parrying Samus's beam shots with his sword except for Plasma Beam.
- Razor Wind: His "Guillotine Blast" technique spins his sword to stir up a whirlwind before slashing at his opponent, trapping them in a Pillar of Light that slices them apart from all directions.

- Suicide by Cop: After becoming overcome by guilt and switching sides to assist the protagonists, a heavily wounded Knight abruptly demands to finish his duel with Samus, who now has her fully powered suit and is much stronger than before.

- Jump Jet Pack: Possess organic thrusters in their backs, which they use to leap at prey and to slide on their stomachs at high speeds.

- Monstrous Cannibalism: After the Amok Mommy is killed, the other Amokmaw eat her corpse. This is depicted only through a distance shot with some "chomp" SFX, as the artist felt that anything more detailed would be too sad and/or graphic.
- Scary Teeth: Have huge rows of needle-like teeth, strong enough to bite through the hull of a spaceship. Made more startling by how their closed mouths resemble a normal penguin's beak.
- Sensory Overload: The vibrations from Joey's Field Knuckle are a Brown Note to the Amokmaw, and manage to drive them off in their first encounter.
