The primary government of the Metroid universe and Samus's primary employer throughout the series. They are generally concerned with keeping the peace of the galaxy and combating threats such as the Pirates and Metroids, but dark factions even within the Federation exist, engineering both the Metroids and Pirate technology for nefarious purposes. Be warned of spoilers.

The Federation Military (Infrastructure Specialists / Marine Corps)
Debut: Metroid Prime 2: Echoes
"Welcome to the GFB Inter-Stellar Network. This state-of-the-art network links
to 98% of the Galactic Federation's 140,328 Permanent-Member Systems. From
Zebes to Corella 5, you'll have full access to the Federation's entire database."
- Breakout Character: They debuted as Red Shirts in Echoes, being already dead by the time you find them. Corruption and Other M have you meeting and working with them, getting the most screen time and plot relevance short of Samus. They then get their own spinoff game.
- 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.
- The Federation: It's right in the name.
- 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: Zig-Zagged. "Echoes" shows their kinetic weapons far quicker at killing an enemy type then your power beam in cutscene, but less powerful when turned on you, and they have limited ammo. They develop a Phazon powered weapon that's superior, but the destruction of Phazon after Corruption means there back to kinetics by Other M. Their version of Samus' Plasma Beam is much stronger then said kinetics, but has enough disadvantages (most notably slow fire rate) to make it situational at best.
- 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.
- Mini-Mecha: The goal of Project Golem was to create suits capable of mimicking Samus's weapons and defensive capabilities. Their powered armor has to be plugged into larger robot suits to achieve this, though, and it seems a few of them need to work together to accomplish what Samus could probably do solo.
- Not So Different: To the Space Pirates. Both involve themselves in immoral bioweapons programs, specifically ones involving metroids, and both attempt to reverse engineer Samus's Chozo tech for their own gain. Given Project Golem, the Lockjaw, equipment gained in Corruption, and the weapons downloads in Fusion, they're clearly better at the latter. Though given their less hostile status with Samus, that's almost a given.
- Powered Armor: They wear combat exoskeletons modelled after Chozo battle armor, but vastly inferior to Samus's Power Suit.
- 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 The 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.
- Telepathy: According to Hunters, there are telepaths in the federation. Whether this refers to an extraterrestrial species within the federation or humans who developed the ability is unknown.
- Video Game Cruelty Punishment: The Halberd-class turrets that protect non combatants and come in three intensity levels. Don't shoot the fleet troopers. Even the otherwise brief period of invincibility provided by Hypermode won't save you from death at the hands of the third intensity level.
- 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.
- 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.
General Adam Malkovich
Debut: Metroid Fusion (mentioned-only), Metroid (Manga) (in person)
"Any objections, Lady?"
Voiced by: Dave Elvin (English, Other M), Rikiya Koyama (Japanese, Other M)
A Federation general, tactical genius, and pseudo-father figure to Samus. After leading a squad to investigate the derelict BOTTLE SHIP he sacrifices himself to destroy the Metroids onboard.
- Adaptational Dumbass: From what we see in the manga, Metroid Fusion's description of Adam as the "perfect military mind" seems to be on point, considering he and his fleet stalled Ridley long enough for Samus to infiltrate Planet Zebes and stop Mother Brain and the Space Pirates. Metroid: Other M, on the other hand, has him making such brilliant decisions as de-authorizing even Samus's non-offensive upgrades, sending his men to different parts of the BOTTLE SHIP to get picked off one by one, not assuring Samus that he's not the Deleter, not authorizing Samus's Varia Feature when she makes it to Sector 3, and randomly shooting Samus in the back for no adequately explained reason, right when there's clearly a Metroid in front of her.
- Adaptational Jerkass: Also in the manga, Adam was A Father to His Men and could be considered Samus's Reasonable Authority Figure. He even holds no ill will towards her when she goes freelance as being under his employ would hinder her potential, even being the one to upgrade Samus's missile and bomb features when she returns to Planet Zebes. In Other M, he doesn't even briefly mourn the losses of Ian in the past and his own soldiers on the BOTTLE SHIP, and treats Samus with disdain after she left, going as far as literally shooting her in the back.
- Authority Equals Asskicking: Is actually seen in battle gear in Other M.
- The Captain: In Other M he leads his squad into the BOTTLE SHIP.
- Character Shilling: Samus puts him on a pedestal and often gushes about him being a genius or a father figure despite him making questionable decisions and treating her with indifference.
- Consummate Professional: Adam is a consummate soldier for the Galactic Federation, stoically sacrificing his own brother to complete a mission. When Samus requests to join his team's investigation of the BOTTLE SHIP in Other M, Adam tells her she can only do so if she conducts herself as if he was her CO again and expects her to follow his commands to the letter.
- 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.
- 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: The character as portrayed in Metroid: Other M. 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, after telling Samus that if she wants in on his investigation of the BOTTLE SHIP then she'll have to conduct herself as one of his soldiers and obey his orders to the letter, he spends most of his time in the command center monitoring her progress and issuing commands. His helpfulness in this regard is questionable.
- 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: In the manga, Adam is portrayed as a supportive commanding officer to the troops under him. Other M retcons him into a borderline stoic soldier who treats Samus coldly as a result of her having left his team to become a bounty hunter.
- 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, and 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.
Fleet Admiral Castor Dane
Debut: Metroid Prime 3: Corruption
"Damn! They're targeting the planetary defense system!"
Voiced by: Timothy Patrick Miller
An admiral of the Galactic Federation fleet who serves as your employer and general mission control in Metroid Prime: Corruption.
- All There in the Script: 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.
- Badass in Charge: The man in complete command of the space forces during the Corruption Crisis and the Horus Rebellions.
- 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 been in service for 18 years, built in tandem with the battleship G.F.S. Olympus. As the AU for the flagship of the 7th Fleet, 242 has had a distinguished career. 242 maintains a positive relationship with many personnel on board the G.F.S. Olympus. Veteran crew members often refer to 242 as "Other Brain," a practice frowned upon by Admiral Dane."
- Cool Ship: The G.F.S. Olympus.
- 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: During the invasion of Urtraghus.
- 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 Father: It is whispered about among his crew.
Debut: Metroid: Other M
- Voiced by: Stephan Weyte
A Federation military commander who arrives to mop up the BOTTLE SHIP incident. He is heavily implied to be involved with the group that created it and subsequently attempted to eliminate those who learned of it.
- Armchair Military: Notes on his concept art indicate that he doesn't go out in the field very often.
- Bald of Evil: If he's part of the conspiracy rather than a jerk following protocol.
- Bullying a Dragon: He mocks Samus to her face. If not for his position of authority, Samus could have easily beaten the snot out of him.
- The Conspiracy: Presumed to be part of it due to his actions towards Samus.
- Evil Is Petty: Crushes MB's hairpin underfoot.
- Graceful Loser: Not particularly happy about it, but he lets Samus leave with Madeline when Anthony turns out to be alive.
- Jerkass: Extremely so. He embodies the Galactic Federation's corruption, having MB gunned down after she'd been incapacitated and deliberately antagonizing Samus.
- Jerkass Has a Point: Standard military protocol wouldn't allow an outside group to just take a federal employee to who-knows-where, especially if that group was known to transport dangerous and illegal materials. Of course, he'd make his point better if he didn't throw in so many evil chuckles while he said it.
- Light Is Not Good: He wears all white and is either a jerkass bureaucrat or a member of a conspiracy
- Man Behind the Man: If he's part of the conspiracy, he's probably this to the Deleter. Of course, that's not to say there's no one behind him...
- No Name Given: Only his rank.
- Obstructive Bureaucrat: If he isn't part of the conspiracy, he's just one of these.
- Obviously Evil: The game does nothing to hide his motives when he shows up at the end of the game. He has his squad fire at an incapacitated Melissa Bergman, steps on her hair clip afterwards, somehow knows of Adam's passing at a time where Samus was the only one to see it, coldly forces Samus to leave the premises, is genuinely surprised to see Anthony (thus implying he sent the Deleter to assassinate Adam's crew), and is prone to Smug Smiler and Giggling Villain tendencies. The only thing missing is a big, neon sign that says "I am not a nice person!"
- Token Evil Teammate: Out of the major GF leaders, this guy's undoubtedly the most unambiguously sinister. Admiral Dane and Alex Miles are unquestioningly benevolent, and Adam Malkovich is still fighting for peace across the galaxy even in Other M.
General Alex Miles
The commander of the Bermuda system expedition and the Operation Golem troopers.
- A Father to His Men: When one of the missions turns out to be a trap, they apologize to you and blame themselves for not anticipating it.
- Ambiguous Gender: Specifically invoked. Alex is a gender neutral name, and you don't get to see their face or hear their voice to decide one way or the other.
- Armchair Military: They don't get involved in the combat operations personally, though they do lead the fleet attack on the Pirates.
- The Captain: Of the G.F.S. Aegis.
- Cool Ship: They command the G.F.S. Aegis.
- Expy: As a Federation fleet officer who serves as the protagonist's mission control, they're one of these to Admiral Dane.
- The Faceless: Only the visor of their helmet is ever seen.
- Mission Control: They dispatches you on various missions throughout the game.
- Mr. Exposition: To make up for the absence of the scan visor, most plot and background details come from them.
- Voice with an Internet Connection: Their role while on missions, feeding you intel and updating your objectives.
Point Man. Anthony Higgs
Debut: Metroid: Other M
"I wanted to give you some cover, but this thing takes forever to charge. I'll save the next shot for you!"
Voiced by: Mike McGillicuty (English), Kenji Nomura (Japanese)
The point man of Adam's squad and an old friend of Samus's. He is the only member of the group to survive the BOTTLE SHIP.
- Affectionate Nickname: Anthony always called Samus "Princess" as a term of endearment, and still does so even after she left the Galactic Federation.
- Awesome, but Impractical: He carries around a Plasma Cannon, which is the Galactic Federation's version of the Plasma Beam. Unlike the Plasma Beam, the Plasma Cannon is heavy, takes forever to charge one shot and has poor accuracy, which isn't really helpful when dealing with the likes of Ridley.
- Back-to-Back Badasses: Him and Samus when confronted by Ridley.
- Bald, Black Leader Guy: Well, he would be leader of his squad as a breach trooper but a General is around, for some reason, so he's obviously outranked.
- Bald of Awesome: He's revealed to lack hair at the end of Other M.
- Big Guy: He's the biggest person in Adam's squad, taller even than Samus.
- Big Damn Heroes: Saves Samus from Ridley. In a less awesome but still important one, he puts the brakes on the BOTTLE SHIP, preventing it from smashing into the Federation HQ and giving Samus time to finish off the Metroid Queen. Finally, at the end, he interrupted the Government Conspiracy and rescued Samus by pulling rank.
- BFG: The Plasma Cannon on his back.
- Disney Death: Ridiculously averted with this gem."Crazy, how something good can come out of something bad."
- The Giant: He's more than a head taller than Samus, who is herself a head taller than the civilians on the BOTTLE SHIP. He also carries around the squad's heavy artillery.
- I Shall Taunt You: To Ridley of all people. The fact that he manages to live to tell the tale only makes it more spectacular."HEY! HEY PUNK! DON'T YOU KNOW HOW TO TREAT A LADY?! You got no style. I better teach you a lesson about subtlety! COME ON!"
- Odd Friendship: He couldn't be more unlike Samus if he tried, yet she considers him one of her closest friends.
- Remember the New Guy?: In the E3 2009 trailer for Metroid: Other M, a Power Armor-clad man greets Samus and says "Remember me?", opening his visor. Samus may have, but Metroid fans did not. A meme was born.
- Something Only They Would Say: Him calling Samus "Princess".
- Token Minority: Although he isn't the only one in the team. Also wonderfully subverted in that the character avoids all the tropes and stereotypes affiliated with the trope.
Debut: Metroid: Other M
- "I'm fine, but did it have to be bugs?"Voiced by: Mark Carr
The demolitions expert of Adam's squad on the BOTTLE SHIP. He is killed when he encounters Little Birdie's second form and is mauled to death.
Debut: Metroid: Other M
- Voiced by: Aaron Thomas
The communications specialist of Adam's squad. He is killed by MB or one of her pet monsters.
- Curb-Stomp Battle: Receives one that leads to his death.
- Dies Wide Open: When Samus finds his body.
- Porn Stache: Seen in the few instances where his visor is up.
- Scars Are Forever: He has a scar over his left eyebrow.
- We Hardly Knew Ye: He has the same sparse encounters as the other squad members. Interestingly, it's clear he's the Deleter who has been killing off the rest of the team one by one. However, he gets killed offscreen and nothing ever comes of the subplot.
Debut: Metroid: Other M
- Voiced by: Hanley Smith
The engineer of Adam's squad. He is shot and killed by the Deleter.
- Dies Wide Open: When Samus finds his body.
- Et Tu, Brute?: He was comfortable enough around the Deleter to converse with his visor raised. He was promptly shot and left to freeze.
- The Engineer: His official role within the squad
- Kill It with Ice: A victim. The Deleter killed him with a freeze gun and left his remains in the artic biosphere.
- Rapid-Fire Typing: When trying to access the BOTTLE SHIP's files.
Keiji "K.G." Misawa
Debut: Metroid: Other M
- Voiced by: Jeff Minnerly
The scout of Adam's squad. He is killed by the Deleter.
- Army Scout: His official role in the squad, not that it gets put to any use.
- Kill It with Ice: Killed the same way as Maurice
- Never Found the Body: The Deleter disposed of it in a pool of lava. As a result, he is officially listed as "Missing in Action" in the post-credits character log.
- The Quiet One: He doesn't really seem like the type who doesn't talk much, but nevertheless he only gets about two short lines in the game.
- Translation Convention: For his name for some reason. In English speaking countries, it was changed to K.G., despite it being Keiji in Japan. Note that the two names are pronounced the same and that there was no reason for it considering the existence of Keiji Okuda in Mass Effect 2, which released roughly around the same time.
- Token Minority: Not completely token due to Anthony but the only squad member of Asian descent.
- We Hardly Knew Ye: As with the others, we don't learn much about him before his demise.
Debut: Metroid: Other M
A black ops assassin planted in Adam's squad on the BOTTLE SHIP to eliminate those who knew too much about its purpose.
- All There in the Manual: The Nintendo Official Guidebook for Metroid Other M reveals his identity, confirming that he is indeed James Pierce.
- Cell Phones Are Useless: The malfunctioning comms of the squad are likely his doing, which makes it easier for him to pick them off one by one. This is one of the hints to his identity.
- Combat Pragmatist: He knows he can't face Samus in a fair fight so he only engages her with the help of a massive construction mech, fleeing as soon as it's disabled.
- The Conspiracy: Tasked with upholding it by keeping the Galactic Federation's corruption a secret.
- Disposing of a Body: He throws the corpse of one of his victims into a lava pit in Sector 3.
- The Faceless: His visor is always shut and opaque.
- In the Back: Attempts this on Adam and MB.
- The Killer Becomes the Killed: His corpse is found late in the game, having run afoul of one of his intended victims.
- Kill It with Ice: A firm believer of this, as seen by his Weapon of Choice.
- Leave No Survivors: His role as the Deleter is to eliminate anyone who knows about the BOTTLE SHIP, whether it's the scientists who worked there, his own squadmates, or one of the galaxy's most renowned warriors.
- The Mole: His served as this in Adam's squad.
- Offscreen Teleportation: After the crane loader boss fight he manages to travel from Sector 2 to Sector 3 and murder another squad member in the space of time it takes Samus to ride an elevator located in the next room from the boss fight. This is the strongest evidence for the theory that there were 2 Deleters, but it's most likely just another example of poorly paced transitions.
- Undying Loyalty: Completely willing to kill his own teammates once ordered and even prepared to go up against Samus. Though that doesn't mean he'll fight fair.
- The Unfettered: He has no qualms about killing his fellow squadmates.
- The Un-Reveal: Downplayed; his true identity is never directly stated in the game itself, but there is enough evidence to finger James Pierce as the most likely culprit, which the official guidebook confirms.
- Weapon of Choice: He favors the freeze gun for eliminating his squadmates.
- What Happened to the Mouse?: The Deleter subplot runs through most of the game before vanishing without an explanation. Even though his body is found later and the player can figure out their identity through deductive reasoning, Samus doesn't find it out for herself (partially justified by the fact that she herself doesn't have fully conclusive evidence of his identity and the only other potential suspect is listed as M.I.A. due to no one else witnessing the body disposal).
Debut: Metroid: Other M
- Voiced by: Jamie Hunsdale
Adam Malkovich's younger brother.
- The Engineer: He was the one sent to repair a damaged drive unit for a space ship.
- I Let Gwen Stacy Die: His death, as well as Adam's refusal to let Samus rescue him in fear of putting more lives on the risk, is what caused Samus to leave the Galactic Federation in the first place.
- Heroic Sacrifice: He died holding off a drive meltdown long enough for the civilians to get away.
- Posthumous Character: He died while Samus was still a member of the Galactic Federation military under Adam Malkovitch's command, well before any of the games.
- Small Role, Big Impact: He only has one short scene before dying, but it lead to the riff between Adam and Samus that's a driving force in Other M and the reason Samus spends the franchise as an independent Bounty Hunter.
Task Force Herakles
Debut: Metroid Echoes
The twenty-two strong crew of the G.F.S. Tyr who were hunting a group of pirates on Aether. Their efforts were put to an end when they came to the attention of the Ing, who soon overran their compound and killed the troopers.
- Apocalyptic Log: Their various journal entries detail their efforts to hunt the pirates, which quickly give way to them attempting to hold their ground against the splinters until eventually the Ing overrun them.
- Final Girl: Gender-inverted with PFC Denys, who manages to escape the massacre at the landing site but gets killed before he can make it to the Luminoth building.
- Final Stand: A number of them make one against the Ing at the landing site.
- Hero-Worshipper: SPC Angseth is this for Samus, excitedly talking about Samus's exploits over chow and griping in her data log that Samus would be out there getting the job done instead of wasting her time on monitor duty. Ultimately it just makes it sadder that she died days before her idol would show up and wipe out the Ing that had been plaguing the troopers.
- The Leader: Captain A.C. Exter was the leader of the task force and the squad leader of Force 1.
- Posthumous Character: They're all dead by the events of the story.
- Reforged into a Minion: Several of them get made into dark troopers through Ing possession.
- Sanity Slippage: PFC Haley took the constant splinter attacks the worst. He started talking to himself all the time, refused to sleep, and nearly shot another trooper while they were on watch. The only reason he wasn't taken off duty was because the crew needed as many hands in the field as possible to fight the splinters, though the others still had concerns that he would snap entirely and end up shooting them. And as for his data log...I hear.Them.Everywhere. They're coming.Can't sleep. Ever.They'll eat me.Eat.
Project Golem Marines
An elite group of marines equipped with armor capable of matching Samus in power and versatility.
- Arm Cannon: Their weapons systems take the form of a cannon that replaces their right hand and forearm.
- Attack Drone: AI combat drones assist marines who don't deploy with a full squad.
- Attack Its Weak Point: The Scan Bolt reveals these.
- Beehive Barrier: The Shield Generator can deploy a spherical version of this to protect you and your teammates.
- Chest Insignia: The missile symbol is painted onto their chests. It's even faintly visible with different paint schemes.
- Color-Coded for Your Convenience: All the mechs are identical so they're differentiated by glowing visors and TRON-like lines.
- Cool Guns: They nearly match Samus's arm cannon in versatility and are mounted onto mechs.
- Death of a Thousand Cuts: The standard energy shots aren't nearly as effective as the various special weapons, but they still pack a punch.
- Fire, Ice, Lightning: The Flame, Freeze, and Shock Shot.
- Freeze Ray: The Freeze Shot
- Healing Shiv: The Repair Capsules are launched like grenades.
- Hologram: They can create a holographic decoy of Samus to draw the Space Pirate's fire.

- Improvised Zipline: They can use a grapple beam-like device to zipline on energy cables.
- Jump Jet Pack: Each suit is equipped with jump jets for short bursts.
- Mini-Mecha: At least twice the size of a normal trooper, though its hard to tell due to the art style.
- Religious and Mythological Theme Naming: Named after artificial servants made of clay from Hebrew folklore.
- Macross Missile Massacre: The missile launcher
- Mauve Shirt: They're the playable characters, which makes them more important than the usual marines, but they're still soldiers, which means there are always people to replace them. One of the cutscenes even shows a crowd of other marines who qualified for the same positions, just waiting for you to die so they can continue on in your place.
- Shock and Awe: The Shock Shot
- Standard Status Effects: The Slow Shot.
- Sticky Bomb: The Proximity Bomb can work like this or as a deployable landmine.
A mysterious individual involved in the B.S.L. station and the suppression of Adam's memories.
Dr. Madeline Bergman
Debut: Metroid: Other M
- Voiced by: Linda K. Morris
The head scientist of the BOTTLE SHIP.
- The Conspiracy: Her work in the BOTTLE SHIP was clearly part of it, but she's ignorant of its goals outside of the station. Based on the Deleter's actions, she clearly wasn't important enough in the hierarchy to be irreplaceable.
- It's All My Fault: Her opinion of the BOTTLE SHIP incident.
- My God, What Have I Done?: She had this reaction when MB began slaughtering the crew of the BOTTLE SHIP.
- Non-Action Guy: When confronted with a threat, she flees rather than try to fight.
- The Smart Guy: She's clearly intelligent given that she was head of the facility that created MB, Nightmare, and cloned Space Pirates and Metroids.
- Sympathy for the Devil: Cries over MB's death at the hands of the Federation, despite everything she did.
- Tragic Mistake: Her hesitation to defend MB when they they attempted to deactivate her caused them to snap and cause the BOTTLE SHIP incident.
Rodney and Virginia Aran
Debut: Metroid (Manga)A married couple on a mining planet, whose child far overshadowed them.
- All There in the Manual: They never appear in the games, largely due to being dead.
- The Cameo: They and Old Bird appear briefly in chapter 8 of Metroid: Samus and Joey, as Samus reminisces about people she has lost.

- Doomed Hometown: Their colony is destroyed by a Space Pirate attack.
- Good Parents: They both seem to be good parents to their daughter. Hell, both of them are willing to die for her.
- Happily Married: They clearly love each other in their brief appearance.
- Heroic Sacrifice: Virginia dies drawing Ridley's attention away from her daughter.
- Mama Bear & Papa Wolf: They're both fiercely protective of their daughter.

- Workaholic: Rodney, to the point where he occasionally Forgets to Eat.
Techno-organic supercomputers created and used by the Federation for a variety of purposes. One of them is the Final Boss of Metroid Prime 3: Corruption, being controlled by Dark Samus.
- Brain in a Jar: Their appearance, plus some mechanical parts.
- Evil Knockoff: Inverted. They are the Good Knockoffs of Mother Brain. Since they weren't made with Chozo technology, they're obviously inferior. The Space Pirates eventually build their own Evil Knockoff of the Aurora Units called Master Brain in Federation Force.
- Hive Mind: They have one. Whether it's telepathic, mechanical, or some combination of the two has yet to be explained.
- Legacy Character: Heavily inspired by Mother Brain both in and out of universe.
- No Biological Sex: They're giant brains, what did you expect? The gendered voices are purely for user benefit.
- Organic Technology: They're giant living supercomputers shaped like brains.
- Voice with an Internet Connection: One serves as this on Elysia.
- Wetware CPU: They were originally made for research before being incorperated into business, government, and military roles. The Olympus-class ships reduce the crew requirements by using one to handle most non-combat roles, allowing them to carry more fighter craft and be armed with more weapons.
- You Are Number 6: Each is identified by a three digit code that serves as a name. Being organic computers, they don't mind.
The Aurora Unit assigned to the GFS Olympus.
- Benevolent A.I.: Generally helpful (and apologetic on behalf of the Federation when they actually do get her in trouble with the PED suit).
- Mission Control: The primary one in Corruption, providing Samus with information and objectives.
- Voice with an Internet Connection: Samus's contact with the Federation while she's on her mission in Corruption.
The Aurora Unit assigned to the GFS Valhalla, stolen during an attack by the Space Pirates, and used by Dark Samus to control the planet Phaaze.
- A.I. Is a Crapshoot: Tries to kill Samus at the end of the game, although this is the result of being Brainwashed and Crazy by Phazon (and possibly its fusion with Dark Samus).
- Apocalyptic Log: Samus can view its final log on the Valhalla, where it explains that the crew's attempts to repel the Pirate attackers has failed, and that they're about to move it from the ship.
- Final Boss: Of Corruption, after fusing with Dark Samus.
- Load-Bearing Boss: Destroying it also causes the entire planet of Phaaze to begin exploding. This is explained in the scans by it being symbiotically linked to Phaaze.
- Red and Black and Evil All Over: Appears primarily black with red highlights during the battle on Phaaze. Since other Aurora Units do not have this color scheme, it's likely a result of the Phazon corruption and/or modification by the Space Pirates since their technology in Corruption has a similar aesthetic.
- Vagueness Is Coming: The last sentence of its final log, where it simply says "Darkness coming.".
- Walking Spoiler: Due to being the key to Dark Samus' plan to take over the galaxy, and the Final Boss.
A Federation AI installed in the ship they provided to Samus after the destruction of her personal craft. Samus privately names it after her former commander Adam Malkovich, whom it reminds her of.
- A.I. Is a Crapshoot: A subversion on at least two fronts. While the Adam AI is technically rogue for disobeying orders at the end of Fusion, said orders were a spectacularly bad idea to follow: he's taking the correct action, and siding with Samus to do so at about the point a savvy player might expect him to start singing Daisy Bell. And on the other front, he likely doesn't qualify as a true AI, given his computer self is his human self's uploaded mind.
- Brain Uploading: Supposedly it is fairly common for leaders and scientists.
- Cryptic Conversation: One reading of his actions toward the end of Fusion posits that he knows darn well who he is and agrees with Samus' assessment of the X Parasites, but for one reason or another isn't initially willing to openly rebel and/or reveal his identity. When his hints end up proving too cryptic for Samus to pick up on, he gives up and spells out his plan.
- Deadpan Snarker: Some of his lines of dialogue will have some bits like this.
- Exposition Fairy: He provides all the info about the X and the SA-X.
- Identity Amnesia: One reading of his actions towards the end of Fusion besides posits that he had 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 Hate Past Me: He berates Samus's past commanding officer for sitting in a safe command room and ordering her into danger, which happens to be himself as a human.
- Mission Control: He guides Samus through most of Fusion.
- The Spock: His diction when he gives Samus orders reads this way. He also explicitly tells Samus to be wary and take alternate routes in the event she finds a superheated room. As an A.I, it's understandable. This contrasts with Samus' memories of his living self.
- Wham Line: "Any objections, Lady?" This convinces Samus that he's the real Adam and can therefore be trusted.
Security Robot B.O.X.
A heavily armored security robot used in Federation facilities. Samus encounters it on the B.S.L. and eventually destroys it.
- Attack Its Weakpoint: The central processing unit, located in the center of its body.
- Brain in a Jar: The nature of its central processor, possibly related to the Aurora Units.
- Collision Damage: It uses its body to fight just as much as the actual weapons it possesses.
- Everyone Calls Him "Barkeep": The Adam AI only calls it a "Security Robot" in dialogue. The full title of "Security Robot B.O.X." (and therefore, the robot's name B.O.X.) is only mentioned in one of the game's map objectives.
- Five-Second Foreshadowing: Section 5 shows immense damage from something massive having run rampant through it.
- High-Voltage Death: The second fight with it takes place in a pool of water, which its damaged body electrocutes.
- Kill It with Fire: One of its attacks is to launch an incendiary bomb.
- Macross Missile Massacre: It can launch clusters of missiles in its second fight.
- Nice Job Breaking It, Hero!: The damage Samus inflicts on it in the first fight is what allows the X to infect it.
A horrifying bio-mechanical weapon created by the Galactic Federation that can manipulate gravity. Fought in Sector 5 of the Biologic Space Laboratories.
- Body Horror: As if its organic components weren't horrific enough already, as it takes damage in Fusion, its face begins to melt off. The first sign you see of this is when it starts weeping through its eye-holes.
- Chekhov's Gunman: The first time you see it, the Nightmare merely swoops around as a roaring silhouette in the background of Sector 5 beyond a glass plane. You later return to Sector 5 only to find the glass smashed to pieces and the main hallways nearly destroyed.
- Clipped-Wing Angel: In Fusion, it goes through multiple phases, but in each of those phases, it just Shows Damage more and more.
- 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.
- Energy Ball: In Other M, it can fire balls of dark energy in various sizes.
- Enfante Terrible: Its death wails in Other M suggest Nightmare is a baby.
- Frickin' Laser Beams: Can fire lasers from its arms. Other M has it use this for a Spin Attack.
- Gravity Master: It can slow Samus down, stop her ability to space jump and cause her missiles to prematurely crash before hitting it. Other M shows it can also create miniature black holes to absorb and redirect Samus' shots. 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.
- Mechanical Abomination: Nightmare is an unholy bio-mechanical abomination with vaguely-explained gravity manipulation powers. And the worst part is that it's man-made.
- Nightmare Face: Six horrid little yellow eyes and saggy, snot-green skin. In Fusion the face starts to melt as you shoot it!
- Not Quite Dead: In Other M, it lies dormant after its first defeat until you backtrack through its area again, causing it to reanimate to fight you. Given that information, it's possible that it's still not dead after its final defeat. Just unable to do anything to fight you since you destroyed its only means of attack and locomotion.
- 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.
- Sealed Evil in a Can: Downplayed and invoked with its stitched-up facemask, which covers up something far nastier.
- Tragic Monster: In Fusion, the first sign of damage it shows is the eyes of its masking popping out and it starts to "weep" tears of green slime, giving the impression of something monstrously unhappy.
Debut: Metroid: Other M
"I was not wrong. The humans were foolish, and I was forced to bring judgment on them, and yet, because of you, I failed. You must understand the weight of your crime. You must pay the price for what you've done."
Voiced by: Sarah Naid
A machine created by the Federation to control their bioweapons. To do so, they took cues from an individual that already demonstrated this capability: Mother Brain.
- A.I. Is a Crapshoot: Basing the MB's AI on Mother Brain, an advanced Chozo AI that rebelled against her creators and established herself as the leader of the Space Pirates, may not have been the best idea. Not helping the case is her strained relationship with Madeline Bergman, and her Federation superiors trying to control her.
- The Beastmaster: She controls various creatures to do the fighting for her.
- Big Bad: Of Other M, as her going rogue, turning on the personnel, and unshackling the Federation's other projects is responsible for the incident aboard the BOTTLE SHIP.
- Brain in a Jar: Her original form before she was given an android body. As she was created to be a recreation of Mother Brain, it's possible she is an evolution of the previous Aurora Units.
- Colony Drop: As seen under Ramming Always Works, she plans on using the BOTTLE SHIP to destroy the Federation headquarters, which is located on a planet.
- Dead Person Impersonation: Passes herself off as Madeline Bergman. Unfortunately for MB, she wasn't actually dead.
- Et Tu, Brute?: Seeing Madeline back-off and do nothing to stop the local security taking her away is what triggered MB's rampage to begin with.
- Fun with Acronyms: At various points in the story, MB stands for Mother Brain, Madeline Bergman and Melissa Bergman.
- HeelFace Door-Slam: Madeline begs "Melissa" to forgive her and stop what she is doing, leading the AI to apparently surrender... only for Federation soldiers to appear out of the blue and shoot Madeline, prompting MB to shield her and go into a Roaring Rampageof Revenge. To prevent another massacre, Madeline is forced to incapacitate MB with a freezing blast, after which the GF troopers promptly gun MB to death.
- Hijacked by Ganon: While Mother Brain was killed in Super Metroid, it's revealed that her AI schematics became the basis for MB in order to control the cloned Metroids. Such schematics also include the capacity to think independently like Mother Brain, which leads her to rebel against her superiors.
- Hive Mind: She's the lynchpin, with every monster and robot on the BOTTLE SHIP under her mental dominion.
- Legacy Character: In universe, she's meant to replicate Mother Brain's control over various organisms.
- Names Given to Computers: Madeline came to see her as a daughter, and named her "Melissa Bergman" when she was given a humanoid body. Unfortunately, she no longer identifies with the name. See Et Tu, Brute? above.
- Post-Final Boss: She is technically the last enemy encounter in Other M, but the fight is short and easy, to the point where it was reported that many players won by accident. The clone of the Queen Metroid is the actual Final Boss of Other M.
- Ramming Always Works: She plans to ram the BOTTLE SHIP into the Galactic Federation headquarters.
- Ridiculously Human Robots: When Samus first encounters her, she mistakes MB for an ordinary human.
- Roaring Rampage of Revenge: Can be heard giggling as she commands the bioweapons aboard the Bottle Ship to slaughter her creators.
- Super-Powered Robot Meter Maids: She's stronger and more durable than a human.
- Telepathy: Presumably how her hive mind works.
- Tragic Villain: How Samus ultimately comes to view her. MB developed a soul after interacting with the Metroids, and this free will led to fears of her becoming a monster like Mother Brain. So instead of submiting to what was essentially a lobotomy, MB rebelled and sparked the entire plot of Other M.
- Turned Against Their Masters: Uses her control of the BOTTLE SHIP inhabitants to massacre the scientists onboard.
- The Unfought: You never get to fire at her in the entire game.
- Walking Spoiler: She's an enigmatic character who was only briefly and cryptically shown off in pre-release promotional materials and whose real identity and full backstory is not revealed until the climax of the game.
