The Federation needs you alive and on duty, Samus...
— Adam Malkovich
Samus Aran is an intergalactic Bounty Hunter and the main protagonist of the Metroid series. Her first appearance was in the original Metroid, released in 1986. Her birth planet is K-2L, an earth colony. Samus Aran is a bounty hunter of prestige fame, often employed by the Galactic Federation. Samus's history is somewhat mysterious and is often left with wide gaps. Her past is best described in the Metroid Manga, although Nintendo has never directly confirmed whether the manga is canon or non-canon; some images from the Manga appear in the Japanese Metroid: Zero Mission Gallery. Other than the Metroid Manga, primary sources for her history are Metroid Fusion and Metroid: Other M.
 Early Childhood
Samus began life as a young girl on the mining colony of K-2L with her parents, Rodney Aran and Virginia Aran. When she was three years old, her hometown was visited by the Chozo, a bird-like race. They were in need of Afloraltite, which was mined on K-2L by the Federation colonists there. They came in peace, and Samus immediately found a kindred spirit in a Chozo elder named Old Bird. He taught Samus that befriending and understanding others can be used to solve problems, demonstrating this philosophy by showing Samus how to befriend Pyonchi, a rabbit-like creature who remains Samus's companion for many years. Rodney Aran refused the Chozo the Afloraltite they sought, and the Chozo ship left K-2L empty-handed.
Unfortunately, a Space Pirate flagship was following the Chozo, hoping for a chance to steal any Afloraltite the Chozo might discover. It landed on the innocent colony and a raid ensued, led by none other than the dragon-like bioform Ridley. Samus, remembering what Old Bird had taught her, attempted to befriend Ridley in spite of his terrifying appearance. Ridley attempted to kill Samus, but Virginia got in the way of the strike, suffering a fatal blow. At the same time, Rodney infiltrated the Space Pirates' vessel and ignited the Afloraltiite the Space Pirates had stolen, thus sacrificing himself and destroying all of the Space Pirates. Ridley was severely wounded, but he survived. The only survivor of the attack was Samus.
Soon after the Chozo left, they received a distress signal from the colonists. Old Bird feared the worst, and ordered the ship to return to K-2L. Old Bird and Grey Voice discovered Samus and brought her to their home planet, Zebes. Mother Brain, a sentient organic robot created by the Chozo, predicted that Samus's frail body could not withstand harsh life in Zebes. The Chozo hoped to evade this problem by integrating Chozo DNA with hers and equipping her with the Power Suit, a bio-mechanical armor with the ability to assimilate many weapons and functions.
 Growing up on Zebes
Into her teenage years, Old Bird and Gray Voice trained her in the ways of the Power Suit. They taught her how to use it and that she must use her power to protect others for the good of the galaxy. After a particularly difficult training session, in which Samus failed to destroy the targets she had been asked to destroy because she was not focusing properly, Gray Voice reminded her that if she wanted to survive and protect others, then she must utilize her abilities to the max; second or third place will never do.
Samus ran off to calm down, and watched an Iono Feria absorb moisture and ionize it to fly. Samus fed the Iono Feria and picked some flowers in the valley where they were feeding. When Gray Voice came to check on her, she showed him the flowers, which were extremely poisonous Badger Clover. Gray Voice and Mother Brain realized that the Iono Feria carried the Badger Clover to Zebes, and Gray Voice ordered for the flowers and the Iono Feria to be burned. Samus objected to the needless shedding of blood, but Gray Voice insisted. The Iono Feria picked up weapons lying nearby and began to defend themselves. Samus took matters into her own hands and shot the weapons away from the Iono Feria. Samus managed to calm down the Iono Feria, and Mother Brain began damage control.
Samus went to a different room to calm down, and Old Bird came to talk to her. He told her that she was ready to leave Zebes and head out on her own. Samus was skeptical, but Old Bird silenced her doubts. Samus resolved then and there to live up to her predecessors' legacy and become the true "Protector of the Galaxy."
 With the Federation Police
At an unspecified point after Samus left the Chozo, she joined up with the Federation Police. While she was in the Police, she was assigned several recon missions, all of which were likely designed to keep tabs on Space Pirate activity in her area.
At one point, Samus was assigned to a reconnaissance mission of the planet Jigrad. She was monitoring Space Pirate activity in the area with her comrades Kreatz and Mauk. They ascertained that the Space Pirates had left a remnant of their forces on Jigrad and were forcing the natives of the planet to build a "gaudy building" for no apparent reason.
Kreatz had just suggested they all report back to headquarters and regroup with the other recon teams when Samus noticed that the Space Pirates had brought in a group of children to work on their construction project. The children were forced to pass through a sensor at a certain height; if a child failed to trigger the sensor, they were dispatched. The adults working on the building implored the Space Pirates to stop killing children to no avail. Samus was surprised by such a cruel act, even coming from the Space Pirates. The Space Pirate began to taunt the little girl he was preparing to kill, As the Space Pirates opened fire, Samus rushed down in her Power Suit and grabbed the girl, using her authority with the Federation Police to place the Space Pirates under arrest. The Space Pirate leader pointed out that Samus was alone and ordered his men to attack, beginning a firefight. Samus sent the civilians to safety, and continued fighting. Kreatz was worried about the consequences of disobeying orders, but he and Mauk joined the fight as well.
After the firefight, there was one Space Pirate left alive. When the Space Pirate happened to crawl underneath the sensor the girl had failed to trigger, Samus decided to kill the Space Pirate just as he had tried to kill the little girl. The Space Pirate begged for mercy, but Samus remembered the murders on K-2L and, in her anger, was going to shoot him anyway. Just then, Samus heard the cries of the little girl, who was immediately comforted by the women of the colony. Samus decided to not shed any more blood and placed the Space Pirate under arrest.
Afterwards, Chief Hardy, the commander in charge of Samus and her friends, reprimanded the three for disobeying orders. The little girl came to thank Samus for saving her, but Samus told the girl that she was the one who had saved her. Samus walked off hand in hand with the little girl, who told Samus her name was Damara.
 Documented Incidents
 First Mission to Zebes
Some time after the Space Pirates had established a power base on Zebes, the Galactic Federation hired Samus Aran to destroy Mother Brain and the Metroids the Pirates were amassing. After defeating Ridley and Kraid, Samus gains access to Tourian. There, she defeated the Metroids and Mother Brain which activated a self destruct sequence. She managed to escape from Tourian but was attacked by the Pirates in orbit around Zebes and her gunship was shot down. This left her without the protection of her Power Suit with only her emergency pistol for defense and with no choice but to infiltrate the Pirates' Mother Ship.
After evading the many Zebesians aboard the ship, Samus finds an ancient test left by the Chozo. After defeating it, Samus gains a more powerful suit that enables her the use of all items she had acquired on the planet. She then works her way to the top of the Mother Ship, where she battles a mechanical version of Ridley known as Mecha Ridley. After destroying the machine, the ship's self destruct is activated. Samus is forced to steal a small Pirate vessel and flee the ship before is destroyed.
 Tallon IV Incident
- Main article: Metroid Prime
After receiving a signal from an unidentified distress beacon, Samus tracks it back to a derelict vessel in orbit above Tallon IV and moves to intercept it. Upon her arrival, she discovers the abandoned Space Pirate Frigate Orpheon, where the Space Pirates performed various experiments on life forms using Phazon. Eventually, Samus comes upon the Reactor Core of the frigate, where a Parasite Queen lurks. Samus defeats it, but it falls down the core, setting off a series of explosions that destroys the frigate. As Samus escapes, she encounters Ridley, reborn as Meta Ridley, who escapes the frigate to the planet's surface. Samus pursues to the surface of Tallon IV.
As she explores, she comes upon the Chozo Ruins. While there, she learns that the planet is slowly being corrupted by the impact of a large Phazon-laden meteor, which has caused the destruction of the Chozo Civilization on the planet. Samus also discovers that the Space Pirates are mining the toxic Phazon and attempting to use it for their own purposes. She happens upon their research labs within Phendrana Drifts at the Glacier One outpost, where the Space Pirates managed to take some of the Metroids from Zebes and were experimenting on them. While in the outpost, she learns of Project Titan and is later forced to defeat its result, Thardus. She also interrupts their mining at the Phazon Mines, and eradicates the results of their Project Helix experiment, the Elite Pirates, Phazon Elite, and Omega Pirate.
Eventually, Samus learns that the source of the corruption was inside the Impact Crater. The crater had been sealed by twelve Chozo Artifacts at the Artifact Temple by the Chozo before their corruption. Amongst their lore, she reads that the Chozo not only foresaw the coming of a Worm, but of the Entrusted One - a prophecy that pointed to Samus herself.
Samus gathers the twelve Artifact and opens the Impact Crater, confronting and defeating Meta Ridley in the process. Inside the crater, she encounters the source of Phazon on the planet, Metroid Prime. As the creature is defeated, it grabs hold of Samus' Phazon Suit, but destabilizes. Samus departs Tallon IV, and leaves for another assignment. However, the Metroid Prime survived, as Dark Samus.
 Aether Incident
- Main article: Metroid Prime 2: Echoes
The disappearance of the G.F.S. Tyr prompts the Galactic Federation to send Samus Aran to investigate. Upon her arrival at the planet Aether, her ship is damaged by magnetic storms and she is stranded on the surface while the ship repairs itself. She discovers that the entire crew of the Tyr has been killed by hordes of creatures called Splinters, and that their bodies have become hosts for an unknown parasitic biomass. As she explores Aether, she happens upon the Great Temple and fights the Alpha Splinter there, acquiring the Energy Transfer Module after defeating it. Afterwards, she meets U-Mos, the Sentinel of Aether and the leader of the Luminoth, who was protecting the final Energy Controller in the Great Temple. He explains that the impact of a cosmic object on the planet caused a division, and that as a result, Aether exists in a state of Transdimensional Flux. He beseeches her to help the Luminoth stave off their enemy, created from that impact, the Ing, using the Energy Transfer Module that bonded with her suit. She accepts, and sets out to collect the planetary energy stolen by the Ing from the Agon, Torvus, and Sanctuary regions to save the Luminoth.
During her mission, she encounters her Phazon-powered doppelganger Dark Samus, Metroid Prime reborn using DNA from Samus and the structure of her Phazon suit, and engages her in combat multiple times. She also dismantles several Space Pirate operations on the planet. She finally makes her way to the top of the dark Sky Temple and kills the Emperor Ing, siphoning the last of the stolen planetary energy. This causes Dark Aether to collapse. As she escapes, she encounters Dark Samus again. She engages her in combat, presumably destroying her, and saves the planet. After the incident, the G.F.S. Anhur comes to the planet and helps the Luminoth rebuild. The crew of the Anhur finds Phazon left behind by the Space Pirates and brings it back with them.
 Phazon Subjugation
- Main article: Metroid Prime 3: Corruption
About six months after the events that occurred on the planet Aether, Samus Aran is again issued an assignment by the Galactic Federation: she is to travel to the G.F.S. Olympus, the flagship of the Galactic Federation, for a scheduled meeting with Fleet Admiral Castor Dane and three other hunters - Rundas, Ghor, and Gandrayda. The four hunters are briefed concerning a digital Phazon virus that had spread to several supercomputers dubbed Aurora Units. During the hunters' briefing, a Space Pirate raid on the Olympus is launched via several Space Pirate Boarding Pods. The Space Pirates then launch an attack on the planet being orbited by the Olymupus, Norion, which is one of the most important military planets in the entire Galactic Federation. Samus, Rundas, Ghor, Gandrayda, and the Galactic Federation give chase.
On the surface of Norion, the hunters and the Federation realize that the Space Pirates have disabled several power conduits that are needed for the digital interfaces to work properly. Aurora Unit 242 suddenly indicates that a Phazon-like meteor, later revealed to be a Leviathan, is about to crash into the planet and will infect Norion in its entirety with Phazon if it is not stopped. Samus and the hunters are dispatched to restore energy to the downed power conduits, which in turn will power an energy cannon that can be used to destroy the meteor. While Samus is engaged in this task, she encounters Meta Ridley, once again resurrected by the Space Pirates. She defeats him and restores power to all the generators.
Once the hunters arrive at the Energy Cannon's controls, they encounter the revived Dark Samus. Dark Samus utilizes her natural ability to generate Phazon and creates a Phazon blast that renders the four hunters unconscious. Samus, however, is able to remain awake long enough to fire the Energy Cannon, destroying the meteor.
 Phazon Enhancement Devices
One month later, Samus awakens and is informed by a trooper that the other three hunters woke up several weeks ago. The hunters were producing Phazon on their own as a result of Dark Samus' attack, but the Federation's medical team noticed no ill-effects, so they outfitted the hunters with Phazon Enhancement Devices. The three hunters had been sent to Bryyo, Elysia, and the Pirate Homeworld to destroy Leviathans that had impacted there, but communications with them were lost shortly thereafter, and so Samus is issued a PED Suit, similar in nature and appearance to those being worn by several squads of Federation Marines, and is issued a new assignment: find and destroy the Leviathans and, if possible, discover what happened to the other hunters.
During the mission, Samus discovers that the hunters show signs of Phazon Corruption due to using the PEDs. Each of the hunters attacks Samus when she encounters them, and Samus is forced to terminate them. While on the Pirate Homeworld, Samus learns that the hunters had been completely consumed by Phazon and were under the dominion of Dark Samus. Dark Samus had even placed them in command of the Space Pirate forces on each planet. As she destroys each Leviathan, Samus's body gradually becomes controlled by her natural Phazon, and it becomes increasingly difficult to maintain control while in Hypermode.
 Destruction of Phaaze
After Samus completes her mission, Aurora Unit 242 announces the discovery of a single planet that is the source of all Phazon, called Phaaze, and that Dark Samus has been controlling it using Aurora Unit 313, stolen from the GFS Valhalla. Samus explores the now-derelict Valhalla and discovers a means of travel to Phaaze: the Leviathans are capable of creating wormholes in order to reach their destinations, and the Space Pirates possess a Leviathan rigged to fly like a ship. While the Federation fleet distracts Space Pirate forces, Samus boards the Leviathan vessel and flies to Phaaze.
When Samus arrives at Phaaze and steps out of her gunship, the sheer amount of Phazon present in her body causes her Phazon corruption to rise to one-hundred percent. Her ship no longer recognizes her, so passage on the gunship is unavailable until she rids her body of the Phazon corruption. She is forced to vent her energy tanks and enter permanent Hypermode, becoming progressively saturated with Phazon the longer she stays on Phaaze.
Once Samus arrives at the Sanctum of the Phazon core, she encounters Dark Samus once again and engages her in battle. Dark Samus is forced to merge with the stolen Aurora Unit 313 as a last resort. With her Phazon levels ever rising, Samus destroys the corrupted supercomputer. Dark Samus emerges from the downed Aurora Unit and makes one last gesture towards Samus before vanishing into a gas of Phazon, never to be seen again.
Samus quickly flees the unstable planet. Her objective is completed, but at great cost; many Federation troopers and ships were lost, the lives of each of the other hunters, and great mental distress to Samus herself. With Phaaze eliminated, the threat of Phazon Corruption disappears. Samus flies off in search of a new mission, but she is followed by a mysterious ship.
 Metroid Homeworld
- Main article: Metroid II: Return of Samus
Some time after neutralizing the threat Phazon posed, Samus is ordered to eradicate the entire Metroid population on the planet of SR388. After battling through the numerous Metroids and other hostile creatures, she arrives in the Queen Metroid's lair and destroys the few remaining Metroids found in it. After a fierce battle with the Queen Metroid, Samus emerges victorious and completes her main objective. However, after heading towards her gunship to leave SR388, a Metroid, the last of its kind, hatches from an egg. Instead of terminating the infant Metroid, Samus takes it to the Ceres Space Colony for the Galactic Federation to conduct research on the specimen.
 Return to Zebes
- Main article: Super Metroid
Shortly after departing from the Ceres Space Colony, Samus receives a distress signal indicating that the colony had come under attack by Space Pirates. When she returns to the station, she finds the scientists dead and the Metroid missing. After further exploration into Ceres, Samus encounters Ridley, who is holding the Metroid. She is unable to defeat Ridley before he flees with the Metroid and activates the station's self-destruct. Samus follows the Pirates to a rebuilt Zebes to finish them off and retrieve the Hatchling.
On Zebes, Samus encounters several enemies she has encountered in the past, such as Kraid. New additions are also added to the Pirate forces. After defeating Kraid, Phantoon, Draygon, and Ridley, Samus gains access to a rebuilt and pulchritudinous Tourian where she discovers a host of Metroids. Deeper within the lair, she confronts the Metroid Hatchling, which has grown to a massive size; it appears to be in its adult stage. The Metroid feeds on Samus's Energy Tanks and leaves her with a single unit of energy before flying off.
Once she recovers, Samus works her way to Mother Brain. Though she manages to destroy Mother's containment vessel, Mother rises up from the ground with a mechanical body. Among her many attacks, Mother fires an energy beam that is powerful enough to immobilize Samus. However, before Mother is able to kill Samus, the Hatchling attacks, draining Mother Brain's energy. The Hatchling then begins replenishing Samus's energy, even as it is assaulted by Mother Brain. After her energy is restored, the Metroid again tries to attack Mother Brain, but it is killed in the process. Samus discovers that as a result of the Hatchling's restoration of her health, all of her beam weapons are replaced by the far more powerful Hyper Beam. She then uses her new-found power to destroy Mother Brain. Immediately after Mother Brain is defeated, a self-destruct sequence is activated. Samus escapes, and the entire planet is destroyed in the explosion.
 The Bottle Ship Incident
- Main article: Metroid: Other M
A few months after her return from Zebes, Samus, who is no longer under orders, receives a distress signal known as "Baby's Cry," which is emanating from a space station known as the Bottle Ship, and takes it upon herself to respond and investigate the facility. Shortly after landing, she comes into contact with the Galactic Federation 07th Platoon, led by her former commanding officer, Adam Malkovich. Although she is initially left in the dark about the Federation's motives (Anthony Higgs is the only person who treats her amicably), she cooperates with the platoon to take down the Brug Mass. Adam allows Samus to aid the Federation if she will accept his one condition: she must obey orders from him.
Her directives take her to three sectors, each with a different simulated environment. She faces many familiar enemies during her stay, along with a plethora of new and bizarre creations, including Nightmare and the RB176 Ferrocrusher. She eventually learns from Madeline Bergman that a rogue group of Federation agents has been, against Federation protocol, genetically modifying the life-forms aboard the ship for use as bioweapons. The group in charge also dispatched an assassin to eliminate anyone who learns this, and this assassin is in the platoon. Much to her surprise, Samus also learns that Mother Brain's AI was used to create an android that could control Metroids, long thought to have been extinguished, and that DNA from her Power Suit was even used to unwittingly clone Ridley.
Her desire to stop the rogue agent and resolve the crisis leads Samus to the Bioweapon Research Center, an off-shoot of the Biosphere, where she meets the real Madeline Bergman, and discovers that she and other scientists accidentally created a Queen Metroid. After a long and difficult battle (made worse with the knowledge that Adam sacrificed himself to destroy Sector Zero), Samus destroys the Queen, shuts down the rebellious android, and leaves the Bottle Ship, which has since been marked by the Federation for destruction. She returns before the Federation destroys the ship in order to retrieve Adam's helmet, but her task is hindered by the appearance of another enemy from her past, Phantoon. With the specter's defeat, a self-destruct sequence is activated. Samus races to and climbs into her Gunship, clad in her Zero Suit. As she places Adam's helmet in the seat beside her, Samus reflects on her experiences on the Bottle Ship and narrowly escapes her demise.
 The X Infestation
- Main article: Metroid Fusion
 Return to SR388
Some time after her return from the Bottle Ship, Samus is tasked with guarding a group of Biologic Space Labs research station employees who are studying the life-forms of SR388 now that the planet is devoid of Metroids. While exploring an underground cavern, Samus encounters and dispatches a Hornoad with a Missile before being infected by an unknown, amorphous organism known as an X Parasite. As Samus begins to return to the B.S.L Research Station, the X infects her central nervous system, causing her to lose consciousness and control of her ship, which crashes into a nearby asteroid belt after ejecting an escape pod with Samus inside. B.S.L. employees find the pod and transport it to Galactic Federation headquarters, during which time the X multiplies inside Samus's body, leaving her in critical condition. Infected organic portions of Samus's suit are surgically removed, dramatically altering her physical appearance, but ultimately the X were too deeply embedded in her nervous system to be removed and she was given a minimal chance of survival. Shortly thereafter, a vaccine is developed from the DNA of the Metroid Hatchling to rid Samus of the X inside her body, granting her the ability to absorb the X to regain health and weapons. She also inherits the Metroids' weakness to cold.
Once she recovers, Samus, clad in the Fusion Suit, is given a new ship with a built-in computer through which she receives orders, which she names after her former commanding officer, and is sent back to B.S.L. Research Station to investigate after it is marred by a large explosion.
 B.S.L. Research Station
Once Samus is on board the station, she is told to uplink to her ship's computer via a Navigation Room in order to receive her mission directives. She is sent to the Quarantine Bay, the station's holding area for the specimens brought from SR388, and discovers that the specimens are infected with X parasites. Samus is then ordered to find and exterminate the X on board the station so as to keep them out of its six simulated breeding environments, or sectors.
Samus travels through each Sector, defeating enemies and acquiring upgrades on the way, including an X-copy of herself, known as the SA-X. Because the SA-X reproduces asexually, like all X Parasites, no fewer than ten are on board the station by the time she defeats Yakuza. With this increase in danger, Samus's objective becomes escaping the station.
Her escape is hampered when she encounters a copy of the frozen corpse of Ridley, the second specimen taken from the Bottle Ship. Its eyes glow when Samus approaches, and she is forced into battle with an X version of her nemesis. After she emerges victorious, Samus learns from her ship's computer that the Federation is approaching the station, having taken an interest in the X. The computer explains that the Federation had been withholding upgrades from her to prevent her from attacking the SA-X, and when Samus and her computer argue over Samus's decision to detonate the station, she learns that the computer is in fact her former commanding officer, Adam Malkovich, who died on the Bottle Ship. Adam informs Samus that it is possible to redirect the station's orbit so that SR388 is destroyed with the station's detonation, and her final mission is to change the orbit and escape the station alive.
Before she reaches the Control Room, Samus is confronted by the SA-X. She manages to reduce it to its base X form, though it flees before she can absorb it. She reaches the docking bay, only to find her ship missing and an Omega Metroid waiting in its place. It attacks her, leaving her at the brink of death. Before it can kill her, however, the SA-X appears, assumes its Samus form, and attacks the Omega Metroid with its Ice Beam. The Omega Metroid damages it and permanently reduces it to its base form. Samus absorbs the SA-X, regains the Ice Beam, and brutally assaults the Omega Metroid with shots to its chest. It dies, Samus's ship returns, and she escapes the station just before it collides with SR388, obliterating both.
 Other Appearances
 Kirby's Dream Land 3
 Super Smash Bros. Series
Samus has appeared in all three games of the Super Smash Bros. series. Her basic special attack is her Charge Beam, which she begins charging when the B button is pressed. She will finish charging when the B button is pressed again, or the beam is fully charged. This can then be fired by pressing B once more. She can fire Missiles, which can either home in on opponents, but with weak attack power, or speed them up, at the expense of their homing capabilities. She also has the ability to switch to Morph Ball form temporarily in order to drop Bombs. Bombs can be used to perform 'bomb jumps' in a similar manner as the Prime series. She uses her Morph Ball form for another attack, Screw Attack, which attacks opponents while jumping highly. She also has a Grapple Beam, which can be used to grab opponents, or the edge of the stage, helping her chances of survival. In Super Smash Bros. Brawl, she also gains the ability to switch between Power Suit and Zero Suit form via her Final Smash. For her Power Suit Final Smash, Zero Laser, she fires a massive full-power beam, which will (almost all the time) KO anyone in it's path, the power of which is so great it shatters her Power Suit, leaving her in Zero Suit form. The broken remnants of the Power Suit can then be picked up and thrown at opponents to cause a small amount of damage. To regain the Power Suit, Zero Suit Samus must utilize her Final Smash again.
Samus also has a major role in Brawl's Subspace Emissary mode. She infiltrates the Research Facility in search of her Power Suit. During her search, she finds Pikachu being used as a power source, which appears to be physically painful. Samus rescues the Pokémon, which alerts the R.O.B.s stationed throughout the facility to her presence. She and Pikachu fight their way through the facility, eventually coming upon three Power Suit clones. They appear to be clad in the Gravity Suit and have glowing purple visors. The pair defeats the clones, and Samus regains her suit. Her victory is short-lived, however, as they soon encounter Ridley, who grabs Samus and scrapes her against the wall. Using its Thunder attack, Pikachu rescues the bounty hunter from the Pirate leader's clutches, and a battle ensues. After Ridley's defeat, Samus and Pikachu meet up with other heroes in the Subspace Bomb Factory, initiating the next part of the story. Samus is one of the characters who can travel through the Great Maze and fight Tabuu.

- Samus is nicknamed "Sammy" by the hunter Gandrayda.
- Samus made a brief appearance in the cartoon series MAD's episode Gaming's Next Top Princess. The series parodies many icons from pop culture and other recent modern events, with Gaming's Next Top Princess focusing on Nintendo females, parodying the television series America's Next Top Model. Samus, along with Princess Peach and Zelda were the three finalists in the America's Next Top Model challenge. Samus might have won, but they did not reveal it. The cameraman, a Lakitu from the Mario series, noted Samus looked stunning without her Power Suit. She was to have a modeling picture with Ridley but a few minutes later, she killed Ridley.

- "Time flies. You were so small, but without realizing it, you've grown so much. Even though we are called "Protectors of the Galaxy", because we leave everything including labor and meditation to Mother Brain, we are a declining species. There's no meaning in keeping a young person like yourself here. It may be time for you to become independent." —Metroid (manga), Old Bird, Vol 1 Ch 2 Pg(s) 30

- "We gave you "Power"! After that, all that's left is master is discipline and your "Heart". And you can only build that on your own.

- "...Yeah. The Space Pirates have been in control for two months. Their main forces have gone on to other planets but, those left behind have been hard at work building this gaudy building. Furthermore, they've gone so far as to forgo machines and force the natives to build it manually." —Metroid (manga), Samus Aran, Vol 1 Ch 3 Pg(s) 12
- "Alright, for now, let's report back to headquarters. In another hour, we'll meet up with the other recon teams and move in for the kill together... And that'll be mission accomplished! We were just here for reconnaissance this time so we had an easy time of that." —Metroid (manga), Kreatz, Vol 1 Ch 3 Pg(s) 13

- "Emergency Order Exterminate all Metroid organisms on Planet Zebes... And defeat the mechanical life form, Mother Brain." —Metroid: Zero Mission prelude (Metroid: Zero Mission)
- "The timing of my escape couldn't have been worse, I was attacked by Space Pirates and left nearly defenseless, stripped of my Power Suit. All I had for protection was my rather useless emergency pistol. Infiltrating the Space Pirate Mother Ship so armed may have been foolish, but I had no choice..." —Samus Aran (Metroid: Zero Mission)
- "Unidentified distress beacon has been tracked to a derelict space vessel in orbit above Tallon IV." —Introduction (Metroid Prime)
- "Unforeseen by sages, a meteor came as if from nowhere, casting a dark shadow of debris over the land with the violence of its impact. Its destructive force spent, the fallen star burned itself out rapidly, and the incident should have faded into memory...but the meteor brought with it corruption. A Great Poison burst forth into the land, a strange energy that clawed at natural life with a ferocity that seemed almost sentient. Bound by our ignorance of this phenomenon, we Chozo could only watch in horror as this dark force slowly began to spread across the surface of Tallon IV." —Chozo Lore "Meteor Strike" (Metroid Prime)
- "Zebes has fallen. All ground personnel are presumed dead, either killed by the Hunter clad in metal or in the subsequent destruction of the underground facilities. Our research frigates Orpheon, Siriacus and Vol Paragom were in orbit at zero hour and managed to retreat. Frigate Orpheon is now docked at Vortex Outpost. Orpheon's cargo appears to have a 100% survival rate; Metroids are healthy but on restricted feeding schedules due to uncertain supply status. We are ready to begin research on the Metroids and other promising life-forms. Security status remains at Code Blue; no signs of pursuit from the Hunter." —Space Pirate Data "Fall of Zebes" (Metroid Prime)
- "Initial transfer of Metroids to Tallon IV research facilities has been completed. Three were terminated in an incident at the landing site, but the others were pacified and transported safely. Initial Phazon infusion testing is under way. We are eager to observe the effects of Phazon on Metroids, especially their ability to absorb and process the energy give off by Phazon sources. Early research suggest a considerable growth in power and size. Whether the creatures will stay stable thereafter remains to be seen." —Space Pirate Data "Metroid Studies" (Metroid Prime)
- "None know if our temple, the Cradle, will prove powerful enough to contain this evil forever. For now, it wraps around that abomination, cutting it off from the world above. But how can we Chozo hope for the Cradle to remain intact when that which it guards writhes in the darkness, growing always stronger? The fate of this world rests with the gathering of Artifacts we call the Cipher, but even it is not all-powerful. It is strong, yes; an enchanted whole made of twelve links. Still, it is finite in its reach, and we who guard it are slowly succumbing. Will the Entrusted One arrive before our vigilance crumbles away? That time rapidly approaches..." —Chozo Lore "Cradle" (Metroid Prime)
- "Many Chozo are gifted with the distant sight, and even more begin to learn it as our harmonization with the universe becomes more and more complete. We peer forwards, seeing prophecy in the ripples of the water, hearing rumors of coming days on the breath of the wind. Though we celebrate the distant sight, many of these visions are dark - the worst of the prophecies, and the most common, tells of the coming of the Worm. Born from parasites, nurtured in a poisoned womb, the Worm grows, devouring from within, until the world begins to rot. Not all prophecies come to pass, of course, but we cannot help but fear this dark portent." —Chozo Lore "Worm" (Metroid Prime)
- "We believe that on some far-off day, a savior will come and continue what we have begun. For that savior, we will leave our ancient weapons and armor - the soul who can gather them will be the Entrusted One, the only being who can reverse the evil that grows here." —Chozo Lore "Entrusted One" (Metroid Prime)
- "--- Mission File 02543 --- 8 days ago, contact with Galatic Federation trooper squad Bravo was lost. --- Contract Agreement --- Locate Federation troopers and render assistance. --- Data Confirmation --- Last transmission received from a rogue planet located in the Dasha region called Aether." —Samus Mission File (Metroid Prime 2: Echoes)
- "The sarge says those "Splinters" remind him of some killer bug he saw on another planet once. All I know is the things are fast and take a lot to drop. Pretty soon we'll have to go to bayonets. Everyone's low on ammo...even Brode, and he's the stingiest grunt I know." —Trooper Logs "SPC F. Triplette" (Metroid Prime 2: Echoes)
- "Bioscans indicate terminated lifesigns in this trooper, and the presence of an unknown biomass with parasitic tendencies. Though the trooper's armor has been compromised, the bulk of it remains intact. Weapon systems remain online as well. Full parasitic fusion has yet to be obtained, resulting in low agility and response time." —Metroid Prime 2: Echoes Logbook "Dark Trooper" (Metroid Prime 2: Echoes)
- "System Alert. Unknown item acquired. Alien technology has bonded to armor systems. Threat scan complete. No negative impact on suit performance." —Acquisition Data (Metroid Prime 2: Echoes)
- "Long ago, a cosmic object fell to our planet, Aether, exploding with great force. A rift was torn in time and space, and a strange power flowed over the world. Where once there was once Aether, there were now two. One of light…and one of shadow, each existing in its own dimension." —U-Mos (Metroid Prime 2: Echoes)
- "It was the end of peace on Aether, for a new race was born that day on the dark world…one filled with hate and terrible power. They are the Ing. The Ing are creatures of shadow and darkness, knowing nothing of peace or mercy. For decades, we stood against them…yet we now lie on the verge of defeat. When Dark Aether was born, our planetary energy was divided. Half for our world, half for theirs. Should one world gain control of this energy, the other will perish. Before you arrived, the Ing had stolen a device from us…one that collects planetary energy. With it, they have weakened our planet to the verge of collapse. But fortune smiled upon us this day, for the Energy Transfer Module…is now bonded with you. With it, you can help us…help us restore our world. You’re our only hope, Samus. Should we fall, the Ing will look to the stars for new planets to ravage and conquer. Your species could be their next victims." —U-Mos (Metroid Prime 2: Echoes)
- "After the Aether incident, the Federation sent the G.F.S. Anhur back to Aether to deal with the pirate base. Upon arrival, the crew and marines of the Anhur assisted the native Luminoth in dismantling an abandoned Space Pirate mining facility. During the operation, the crew detected the presence of Phazon. The ship’s crew investigated and collected several kilograms of ore, which would later lead to the development of the PED." —Galactic Federation Data "Anhur Incident" (Metroid Prime 3: Corruption)
- "Though located on the fringe of the Federation, the planet Norion is of great importance. The military maintains a strong presence in this sector, and the base on Norion is often the first line of defense against enemies that operate outside of GF space." —Galactic Federation Data "Planet Norion" (Metroid Prime 3: Corruption)
- "Our attempts to intercept the Federation ship departing Aether were unsuccessful. With them went a collection of Phazon, the first to fall into Federation hands. They foolishly left most of the Phazon behind, allowing us to quickly collect what we could. But in our haste we took more than mere Phazon. 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." —Space Pirate Data "Stowaway" (Metroid Prime 3: Corruption)
- "The Phazon Enhancement Device is designed to harness the energy of Phazon minerals, originally discovered on Aether, for a new Federation weapon system. It is being tested on GF Marine battalion stationed in the Norion system. Marines can initiate an energy siphon from a supply of Phazon carried in a backpack into their armorsuits. This allows them to temporarily enhance the exoskeleton and weapon systems to their armorsuits. To date, no marines have displayed signs of “Phazon sickness." —Galactic Federation Data "Phazon Enhancement Device" (Metroid Prime 3: Corruption)
- "Command has received disturbing reports from Bryyo. Contact with our outpost there has been terminated. A coded bliptrans showing Commander Rundas falling in battle to Samus has arrived. Worst of all, the Bryyonian Seed has been demolished. The Hunter's might is great, and she is as efficient as ever when it comes to disrupting our operations. Our spies within the Federation tell us she travels to Elysia soon. We plan on having an appropriate welcoming party in place for her when she arrives. Commander Ghor is a very...accommodating host." —Space Pirate Data "Bryyo Falls" (Metroid Prime 3: Corruption)
- "The march of the Hunter continues, much to our dismay. She has smashed our line at Elysia, taking down Commander Ghor in the process. The accursed Elysian machines were no match for Aran's guns, and now the Federation has control of their spy station once again. It is only a matter of time before they find the location of the Phazon source and send their fleets to lay siege. Our great leader does not seem to mind these setbacks. If Samus comes to our Homeworld, she will find us ready." —Space Pirate Data "Disaster at Elysia" (Metroid Prime 3: Corruption)
- "Mistress Gandrayda is the last of our leader's field commanders. We hope that she will succeed where the others have not. We hope that she will slay the wretched Hunter! Gandrayda tests our mettle often. She moves among us in our form, watching us, looking for signs of weakness. Several unfaithful disciples have been ended...violently. Those who survive will be stronger, ready for the Hunter that comes for them from the void. Gandrayda has vowed to present Aran's bloody helmet to Dark Samus as tribute. We hope she fulfills that vow!" —Space Pirate Data "Mistress Gandrayda" (Metroid Prime 3: Corruption)
- "The vision of our leader is vast indeed. As we prepared for war with the hated Galactic Federation, she decided she required one of their great machines to better control her living planet. We then set out to bring an Aurora Unit to Dark Samus. Bribes led us to the location of our prize: the battleship Valhalla. Crewed with green recruits on a training mission, she was ours for the taking. One of the mightiest ships in the cosmos was no match for the Phazon-powered weapons of the Colossus. We rendered Valhalla helpless, then sent raider to claim our prize. The Aurora was ours! There was no mercy for the Federation dogs. At the command of Dark Samus, we jettisoned the crew into the frigid depths of space, leaving the wreck of Valhalla as a warning to the Federation. Let them tremble before our might!" —Space Pirate Data "Taking Valhalla" (Metroid Prime 3: Corruption)
- "Our leader provided us with great wisdom on many subjects, including the improvement of our mighty battleship, Colossus. We followed her teachings, and turned our vessel into a ship without peer. But more work remained! Dark Samus required a mighty flagship, one to strike terror in the hearts of her enemies. The might of Colossus was not enough. She demanded more! Her solution was unique and most excellent. We took her great star-beast and fitted it with cybernetic weapon systems. Crew quarters and command consoles were placed within the beast's skull. In time, we created a mighty dreadnought, and called it Leviathan. The great leader was pleased." —Space Pirate Data "The Leviathan" (Metroid Prime 3: Corruption)
- "Gunship no longer identifies you as Samus due to near total corruption. Access to ship is not permitted." —Scan Data (Metroid Prime 3: Corruption)
- "Due to critical levels of internal Phazon corruption, the emergency vent override has been triggered by the PED Suit. All acquired Energy Tanks have been vented to temporarily prevent total corruption. Hypermode weapons no longer require the extinguishing of an Energy Tank to use. You are now permanently in Hypermode." —On-screen Data (Metroid Prime 3: Corruption)
- "Unfortunately, this vent override can no longer be used. Damage, as well as exposure to Phaaze's atmosphere, will continue to raise your Phazon level. Your Phazon level is shown as a yellow bat at the top of the HUD. If your Phazon level fills completely, you will die." —On-screen Data (Metroid Prime 3: Corruption)
- "So, the Galactic Federation called its members to an urgent conference to find a way to overcome this menace. They quickly came to one conclusion, which was unanimous and simple...... Give Samus Aran the order to exterminate the Metroids!" Metroid II: Return of Samus Instruction Booklet, Pg 5
- "But, I had hardly gone beyond the asteroid belt when I picked up a distress signal! Ceres Station was under attack!" —Samus Aran (Super Metroid)
- "Just when it seemed peace and order had been restored, Samus received an emergency directive from the Galactic Federation: Emergency! Emergency! Return immediately to the Space Science Academy!" Super Metroid Instruction Booklet, Pg 5
- "When Samus made her way to the research facility, she found the building in ruins and the Metroid larva was nowhere to be found. Out of the darkness came a group of Zebesian space pirates and their leader, Ridley, who had the Metroid larva in tow. The pirates fled to a rebuilt planet Zebes and Samus followed them, resolving to finish them off and save the hatchling!" Super Metroid Instruction Booklet, Pg 5
- "Code name: 'Baby's Cry.' A common SOS with the urgency of a baby crying... The nickname comes from the fact that the purpose of the signal is to draw attention. The signal was coming from a remote part of space. I altered the course of my ship as if this detour had already been part of my flight plan. Baby's Cry... It was as though it was crying specifically for me..." Metroid: Other M Instruction Booklet, Pg 3
- "It's artificial intelligence. We developed an AI program that would reproduce Mother Brain's thought processes. We called it MB." —MB (Metroid: Other M)
- "Metroid remnants were attached to your suit when you returned from Zebes. They were reproduced by a piece of cell structure salvaged by the Federation, and they are in this facility." —MB (Metroid: Other M)
- "At first, no one thought that the creature was Ridley. They didn't think it had potential as a bioweapon at all. They raised it like a pet, calling it Little Birdie...until one day, when it attacked one of the researchers and got away. Ridley had played dead and lured the scientist into his cage. What was left...it was a horrible sight." —MB (Metroid: Other M)
- "What you met was MB. She's an android. She was created with the intellectual data of Mother Brain and consequently developed Mother Brain's consciousness as well." —Madeline Bergman (Metroid: Other M)
- "I'd been assigned to watch over Biologic's research team, so I once again found myself on the surface of SR388." —Samus Aran (Metroid Fusion)
- "It was there that I was attacked by a life-form I had never encountered before. It was only later that I learned the identity of my attacker: the parasitic organism we now know as X. Unaware of my condition, I was returning to the station when disaster struck." —Samus Aran (Metroid Fusion)
- "Once the X had infested my central nervous system, I lost consciousness and my ship drifted into an asteroid belt. The ship's emergency systems automatically ejected the escape pod before impact. Biologic's vessel recovered it and transported me to Galactic Federation HQ." —Samus Aran (Metroid Fusion)
- "However, during the journey, the X multiplied within me, corrupting large areas of my Power Suit." —Samus Aran (Metroid Fusion)
- "It then came to light that the organic components of my Power Suit had become so integrated with my system that it could not be removed while I was unconscious. Large portions of my suit had to be surgically removed, dramatically altering my physical appearance. However, the X in my central nervous system were too embedded to be removed safely. I was given a minimal chance of survival." —Samus Aran (Metroid Fusion)
- "Then, someone found a cure. They proposed using a Metroid cell to make an anti-X vaccine. It seems that the Federation had managed to preserve a cell culture from the last infant Metroid from SR388. The serum was prepared and injected without delay. The X parasites were immediately and completely destroyed. As for me, one life ended... yet I survived, reborn as something different. Pondering this fact, I realize... I owe the Metroid hatchling my life twice over." —Samus Aran (Metroid Fusion)
- "Don't be so surprised, Samus. you know that the X reproduce by asexual division. Because of this mechanism, there are now no fewer than 10 SA-X aboard the station." —Ship's Computer (Metroid Fusion)
- "The Federation has taken an interest in the X and SA-X. They believe this life-form had endless potential applications." —Ship's Computer (Metroid Fusion)
- "They knew you would try to destroy the SA-X... That's why they stopped sending you support data... The Plasma Beam modification was ready some time ago, but they withheld it to keep you from engaging the SA-X. Yet somehow you restored that function on your own... They also tried to withhold the Diffusion Missile upgrade because they didn't want you to grow too powerful. But they had already sent it, and you tracked it down... Bravo, Samus." —Ship's Computer (Metroid Fusion)
