Of course she's a bit like Ripley from Aliens (Sigourney Weaver), but a little more extravagant.

Yoshio Sakamoto on Samus Aran in Metroid[1]

Nintendo Power Super Metroid comic.

The Metroid series appears to have borrowed many elements and plots from the Alien film franchise. Yoshio Sakamoto has occasionally made comparisons[2] and Nintendo Power #58 claims that Samus Aran's physical appearance in the Super Metroid comic was partly based on Ellen Ripley (as well as Leia Organa from Star Wars). Below is a list of perceived similarities between the series.


I think the film Alien had a huge influence on the production of the first Metroid game. All of the team members were affected by HR Giger's design work, and I think they were aware that such designs would be a good match for the Metroid world we had already put in place.

Yoshio Sakamoto on Metroid[3]

I was inspired by the first spaceships drifting in the darkness of space. I wasn’t inspired by Alien’s music, but I was fascinated by the senses of urgency, tension and uneasiness that dominate the whole movie. I was affected by that mood of not knowing when something would happen.

Hirokazu Tanaka[4]

  • Both Metroid and Alien feature a female lead protagonist, Ellen Ripley in Alien, Samus Aran in Metroid.
  • The director of Alien is named Ridley Scott. A miniboss in Metroid (who became an antagonist in later games) is named Ridley.
  • Nostromo's ship computer is called "Mother". The antagonist of Metroid is Mother Brain.
  • Alien features eponymous creatures also called Xenomorphs, whose first stage of life latches on to the face. Metroid features eponymous creatures (specifically, the larval form) that latch onto the head (faces in the Metroid Prime series).
  • The end of the film shows Ripley barely escaping from the exploding Nostromo. The end of the game shows Samus barely escaping from the exploding Tourian facility. Both characters are the sole survivors of the explosion (apart from Ripley’s cat, Jones).
  • Ripley ends up scantily clad near the end of the film. Samus ends up scantily clad near the end of the game (if certain requirements are met).
  • Ridley's original design resembles a Xenomorph, most notably with his elongated head, comparatively small mouth, and long pointed tail.
  • The Xenomorph Aliens have a second mouth on their tongues which is round and has many teeth. The design of the Metroid larvae is similar to this.
  • The design of the Chozo Statues is possibly based on the fossilized Engineer found in Alien.
  • Parker constantly suggests to the rest of Nostromo's crew that they should "freeze" Kane, who has a Facehugger attached to him. This may have inspired the Metroids' weakness.
  • Samus's gender was either hidden or falsified in the manual, depending on the region the game was released. In the Alien script, Ripley's gender was not specified.
  • In the Japanese version of the game, the Title Screen has the font arranged in a similar manner to the title logo for Alien.

Metroid: Zebes Invasion Order[]

  • The game's second half possesses several elements from the first Alien movie. Most notably:
    • Metroid=Mutant stalking Samus aboard her gunship is reminiscent of the Xenomorph in the first movie stalking the Nostromo crew for most of the film, including Ripley.
    • In one possible scenario, Samus boards an escape pod and evacuates her compromised gunship just before it explodes, and she has a brief moment of respite where she believes the M=M was killed in the exploding ship. Upon discovering that the M=M has survived and made it inside her escape pod, Samus can open the airlock and knock the alien out into the vacuum of space. This sequence is incredibly similar to the climax of Alien.
    • Samus enters cryostasis after destroying the Pirate Ship, seemingly destroying M=M with it, similar to the ending of Alien where Ripley enters cryostasis.

Metroid II: Return of Samus[]

It's no secret that Nintendo was influenced by Ridley Scott's space horror masterpiece, Alien, when making Metroid.

Official Nintendo Magazine issue 59, page 68: "Homages to Alien"

  • In Aliens, Ripley travels to the source of the Alien species, LV-426. In Metroid II, Samus travels to the source of the Metroid species, SR388.
  • Both center around the female lead attempting to exterminate the eponymous species of their franchise.
  • Aliens go through a life cycle beginning with hatching out of an egg and then metamorphosing. Metroids also go through the process of metamorphosis.
  • Both the Metroids and Aliens molt and outgrow their shells as they mature.
  • The Zeta Metroids are known to spit a type of damaging fluid. The Xenomorph in Alien3 has been shown to spit acid as a form of attack.
    • The aforementioned Metroid also bears some resemblances to the Xenomorph species in terms of physical features, but the Omega Metroid, in particular, bears a close resemblance.
  • Aliens features a final battle with the Queen Alien, the very Alien producing the entire species. Metroid II features the Queen Metroid, similarly.
  • It is implied when entering Phase 9 that the Queen Metroid had not only promptly birthed 9 extra Metroid Larvae of her own will but also dispatched them throughout the area as a final line of defense. This is similar to how the Queen Alien was implied to command her eggs to hatch in the climax to Aliens. Similarly, the Queen was also implied by her attacking Samus and the discovery of the Metroid egg behind her to be extremely protective of her offspring, similar to the Alien Queen in the same movie.
  • Ripley saves and bonds with a surviving colonist, a young girl nicknamed Newt. Samus saves and bonds with a newly-hatched Metroid, nicknamed "Baby".
  • Once again, Ripley ends up scantily clad at the end of the film and Samus ends up scantily clad at the end of the game if certain requirements are met.
  • This game heavily implies that the Chozo were responsible for the Metroids creation, which was similar to the pre-Alien: Covenant theory that the Space-Jockeys were responsible for the creation of the titular Xenomorphs.

Super Metroid[]

  • In Alien3, Newt is killed. At the end of Super Metroid, the baby sacrifices itself. Ripley also sacrifices herself at the end of the film.
  • In the Super Metroid comic, Samus's appearance was partially inspired by Ripley, as well as Princess Leia from Star Wars.
    • On a similar note, Armstrong Houston may have been named after Captain Dallas from Alien, largely due to both surnames being derived from locations in Texas.
  • Kihunters have the ability to spit acid at Samus. The Alien in Alien3 spat acid in one instance at the face of the prison janitor.
  • The way Kraid can fire spiky projectiles out of his stomach is a possible reference to how the aliens in the Alien series burst out of people's stomach.
    • In addition, the cry that Mini-Kraid makes is similar to that of the titular Xenomorphs in the franchise.
  • Compared to his original design, Ridley's new design introduced in this game bears a much closer resemblance to the Xenomorphs, including his rather skeletal appearance and his long barbed tail used to impale his foes.
  • In the final countdown, Samus takes a detour to save the Dachora and Etecoons; in Alien, Ripley takes a detour to save Jones.

Metroid Fusion[]

  • In Alien Resurrection, Ripley is cloned and an Alien Queen embryo is surgically removed from her body. It leaves behind DNA that turns Ripley into an Alien/Human hybrid. Similarly, parts of Samus' Power Suit are surgically removed when she is at risk of death, and she is given a Metroid vaccine created from DNA cells of the Baby, turning her into a Metroid/Human hybrid.
  • The Genesis creatures pay homage to the locomotion of the Alien creatures in the films.
  • Serris has a clear plate on top of its head, making its brain visible. In the Alien franchise, some Xenomorphs are depicted with a transparent plate on top of their head, allowing one to see their brain.
  • The appearance and lunging attack of the Fune/Namihe may be a reference to the inner jaw of the Alien.
  • Weyland-Yutani clones the Aliens from Ripley's embryo for use as bio-weapons. The Galactic Federation uses the Baby's cells to also create the Restricted Lab that Samus later discovers and destroys.
    • Interestingly enough, the Federation already seems to possess a bio-organic weapon for military purposes, the Nightmare.
  • The Alien creatures do not attack Ripley due to them thinking that she is one of them. The Metroids do not attack Samus for the same reason, with the exception of the Omega Metroid.
  • The scene where Samus discovers the Restricted Lab may have been inspired by the scene in Resurrection where Ripley discovers the lab containing her seven predecessor clones, all of which are heavily deformed. Both laboratories are ultimately destroyed by the female protagonist (albeit indirectly in Samus's case).
    • Similarly, Samus ended up being indirectly responsible for the Baby clones' destruction due to the SA-X stalking her to the Restricted Lab, causing the lab to jettison into space and self-destruct, similar to how Ripley 8 in Alien Resurrection killed the "newborn" by using her acidic blood on a wall and forcibly shoving the "newborn" directly on the hole, having it undergo violent decompression as it was sucked into space through the tiny opening in the climax.
  • The Federation also wants to use the X Parasites (including the SA-X) for military purposes, similar to the intentions of the Weyland-Yutani company throughout the Alien films.
  • The escape sequence for Fusion is strikingly similar to that of Aliens. In both sequences, Ripley/Samus are left stranded with no means of escape, and the Queen Alien/Omega Metroid attacking them. At the last minute, their ship flies in and rescues them, and they escape the station.
  • The Auriga spaceship that the entire film took place on is set by the android Call to collide with Earth. The Biologic Space Laboratories research station is set by Samus to collide with SR388. Both are done to prevent the antagonistic organizations from getting their hands on the Aliens/X.
  • Samus distrusted her ship's computer but later came to accept and trust it after it was revealed to be Adam Malkovich. Similarly, Ripley distrusts Bishop 341-B, an android, due to experiences with another android in Alien, but he later redeems himself and earns Ripley's trust.
  • A corrosive green liquid is seen in Sector 1 (SRX). Aliens bleed corrosive green blood. This liquid is also present in Metroid: Zero Mission.
  • The X Parasites spread in a similar manner to the Xenomorphs in the Alien series. In this instance, Samus is infected and her infected suit parts are sent to the BSL, while in Alien Kane is brought on board the Nostromo with the Chestburster inside him. Both events set the respective plots in motion. In Aliens, Newt's father is infected and brought back to the colony, therefore starting the whole infestation and deaths of everyone except for the protagonists.
    • In addition, both lifeforms parasite their hosts from within their bodies and eventually kill them upon reaching a mature stage, with differences, since it's more graphic in Alien than it is in Metroid.
  • At the beginning of the game, the survivors are all but rumored to be dead. However, Etecoons and Dachoras somehow managed to survive the X infestation for unknown reasons. This is synonymous with Newt, who was the only survivor of the colony during the infestation in Aliens. Additionally, both eventually escape the colony in the end.
  • Each shoulder of the SA-X's final form resembles the head of a Xenomorph.

Metroid Prime[]

  • The body of the Baby Sheegoth creature somewhat resembles the head of the Alien.
  • Before detaching from its egg sac, the body of the Queen Xenomorph seems to be an obvious inspiration for the design of the titular Metroid Prime.
  • The opening sequence of Metroid Prime bears a big resemblance to the first movie’s opening. (Shot of the space, Planet Tallon IV in the background)
  • Frigate Orpheon is heavily influenced by the design of hallways in Aliens. Hallways are hexagonal shaped, just like in the second movie. Some creatures walk around the ventilation ducts just like Xenomorphs.
  • The Metroids' method of latching on to their prey in this game and to a certain extent other games in the Prime series had them latching directly on their prey's face rather than their heads, similar to the Facehugger stage of Xenomorphs in the Alien franchise.

Metroid manga[]

  • Pyonchi, Samus's Rabbit-Squirrel pet, serves the same role as Ripley's cat Jones, being the pet of the main character. Both Pyonchi and Jones survive life-changing events along with their owners and are left in the care of someone else as their owners go on different missions. What becomes of them afterward is also unknown.
  • Ridley crushing Chief Rodney Aran and Virginia Aran's heads with his hands in Samus's PTSD hallucination resembles how the Xenomorph killed some of the crew members in Alien. Likewise, Ridley's impaling Grey Voice with his tail resembles how the Queen Alien dispatched Bishop in Aliens.
  • Samus being the sole survivor of the Space Pirate raid on K-2L is similar to Newt's status as the sole survivor of the Xenomorph infestation on the colony in Aliens.

Samus & Joey[]

  • At one point, Samus saves herself from engulfment by Megaroids via thermal shock by using her Plasma Beam and Ice Beam in tandem. Similarly, near the end of Alien3, Ripley exposes the Dog alien to the heat of the factory's molten lead, and quickly turns on the sprinklers, causing its exoskeleton to rapidly shatter, also via thermal shock.

Metroid: Zero Mission[]

  • The scene where Samus is shot down and crash lands back on Zebes is similar to the opening scene of Alien3.

Metroid Prime 2: Echoes[]

  • Aether having a turbulent atmosphere that damages the protagonist's ship and leaves them stranded on the planet is a concept that also appears in Alien, where the Nostromo lands on LV-426 until repairs are complete.
  • The Splinter hive in the Federation Marine' Ops base and the discovery of the dead troopers caught in webs is similar to the discovery of the Alien hive and cocooned colonists in the colony complex in Aliens as well as in a deleted scene from Alien.
  • The scene revealing that the Splinters managed to kill off the entire task force is similar to the hive discovery scene in Aliens, which kill all Marines except for Corporal Hicks, Privates Hudson, and Vasquez and Lieutenant Gorman, who all later die.
  • The Ing themselves are similar to the Xenomorphs, being insectoid, highly aggressive alien creatures, black in coloration, and who use other races as hosts to expand their numbers, and have a Monarch hidden deep within the world guiding their actions, which is then killed in the climax.
  • The scene where Dark Samus aims at Samus during their first encounter is stated in the game's storyboard art to reference a scene in Aliens (specifically, the climax where Ripley uses her flame gun to finish off the Queen Alien).[5]
  • Dark Samus resembles the Alien creature slightly due to her black coloring, skeletal feet and clawed fingers.
  • The Chykka boss resembles the second stage of the Alien life cycle, the Chestburster.
  • The character PFC G. Haley is the weakest Marine emotionally, similar to Private Hudson in Aliens. They are both later killed.
  • The Ancient Chozo Robot in the game's early draft, Metroid 1.5, is an exoskeleton similar to the loader at the end of Aliens.
    • The Humetroid in that same draft may be a reference to the Newborn in Alien Resurrection: Both are a mix between a human and the titular monster.
  • Klaus Schneider, a character from Episode of Aether, slightly resembles Corporal Hicks.
  • Miguel Luis Garcia, also from Episode of Aether, suffers acid burns to his arm, which is another similarity to Hicks, who suffers burns to his chest and half of his face.
  • The Dark Grenchler bears certain physical traits that make it similar in appearance to the Alien.

Metroid Prime Hunters: First Hunt[]

  • The Survivor mode description mentions "Xenomorphs", referring to all the enemies in the mode and the Alien creatures.

Metroid Prime 3: Corruption[]

  • The scene where Samus awakes from a nightmare (in which Dark Samus is reborn and is released from an exploding Phazon canister) might have been inspired by another nightmare scene in Aliens (in which a Chestburster erupts out of Ripley while she is in the hospital).
  • One scene during the invasion of Norion depicts Ghor fighting a Berserker Knight in his armorsuit. This is similar to the climax of Aliens, where Ripley battles the Alien Queen with an exosuit cargo loader.
  • The Berserker Lord's head strongly resembles that of a Queen Alien.
    • Coincidentally, the first Berserker Lord's defeat, where it cornered Samus Aran at a docking bay, only to end up forced out into space by Samus, was similar to that of the Queen Alien in Aliens, where it cornered Ellen Ripley and eventually was knocked into space.
  • Later in the game, the other Hunters become corrupted by Phazon and Samus is forced to kill them. This is a recurring element in the Aliens series, in that the protagonists sometimes have to face the choice of killing their comrades because they have been impregnated with a Xenomorph embryo (Ripley killed herself in Alien3 and wanted to kill a surviving Xenomorph host in Alien Resurrection. This theme has also appeared in the spin-offs and crossovers of the franchise).
  • Samus is the last of the original group of four Bounty Hunters hired by the Federation. In the first and in the beginning of the third Aliens film, Ripley is the sole survivor while her comrades are killed.
  • In Aliens, Ripley seemingly destroyed the source of all the Xenomorphs in a nuclear explosion. Likewise, Samus destroys the source of all Phazon by causing the planet Phaaze to explode. Additionally, there are numerous Phazon Metroid hives and eggs on the planet. This is similar to the Xenomorph Hive in Aliens.
  • When out of his armorsuit, Ghor is a gentle person and very compassionate, but his armorsuit notably alters his personality to become more violent. This is similar to Ripley during her cloning in Alien Resurrection, whose enhanced strength also enhanced her violence.
  • The countdown to the destruction of the Spire Dock is similar to the countdown of the original Alien, in that the female protagonist willingly activates a self-destruct mechanism to accomplish an objective and goes to the escape pod, but is forced to make an unexpected detour before escaping.
  • Aliehs III, the planet where Samus's gunship in Corruption as well as the G.F.S. Olympus were created, is similar to Alien3.

Metroid: Other M[]

Ripley Samus comparison.png

  • The whole concept of Samus picking up a distress call from an abandoned colony, investigating it with a group of Marines, and every member of the Marines being slowly killed off with one soldier, Samus, a survivor of the BOTTLE SHIP and a remnant of another Marine surviving are all similar to the plot of Alien, wherein Ripley's crew is forced by contract to investigate a distress beacon, let a Facehugger on board to attempt and remove it, and eventually everyone except for Ripley is killed. It is also, to a lesser extent, similar to Aliens.
  • Adam Malkovich is hostile towards Samus for leaving the Federation Army due to "a certain incident". Similarly, in Alien3 the superintendent Harold Andrews believes Ripley to be incredibly disruptive to the status quo in the prison when she crash-lands there. Anthony Higgs in Other M and Leonard Dillon in Alien3 are the only two inhostile toward Samus and Ripley.
  • Anthony Higgs shares many similarities with Corporal Dwayne Hicks from Aliens. Both of them are the sole surviving soldier from their squad, and share a close bond with the protagonist.
    • There is a black man in every Alien movie, so Anthony Higgs might have been a reference to this trope.
  • The "Baby's Cry" coming from the BOTTLE SHIP is like the warning signal from the downed vessel on LV-426 in Alien.
  • The RB176 Ferrocrusher that Samus battles strongly resembles the loader that Ripley used at the end of Aliens. "Ferro" is also a character in Aliens.
  • MB's personality as a rogue android is likely inspired by that of Ash in Alien, both have a condescending view of humans.
  • One of the soldiers (The Deleter) is actually an assassin working for traitors in the Galactic Federation who want to use Metroids as bioweapons. The Deleter tries to kill the whole 07th Platoon, Samus and MB to erase all evidence of the traitors' involvement. This element occurs often in the Alien series; usually in every Alien film there is an individual working for the government in the group of survivors (like Ash in Alien and Carter Burke in Aliens) who intends to recover a Xenomorph and, usually, kill all the other survivors in the process to remove all evidence.
  • The scene where the Deleter kills K.G. Misawa by throwing him into Lava is similar to the scene of Ripley's death in Alien3.
  • Samus was used without her knowledge to create bioweapons, using clones of DNA samples extracted from her suit. This mirrors Alien Resurrection quite closely as Ripley was cloned for a similar purpose; for the extraction of a Queen Alien within her body which can reproduce Aliens. In Other M a Queen Metroid is also created, just like Alien Resurrection.
  • Little Birdie's husk, along with the Mystery Creature's, is similar to the way in which an Alien leaves its host, by breaking out of the rib cage. A character also discovers evidence of the creature's metamorphosis into a larger stage through discovery of shed skin in Alien.
  • The Mystery Creature itself has features that make it similar to the Alien. It has a skeletal, segmented tail and what appear to be vestigial wings similar to the Alien's dorsal fins. It also has green blood, along with Ridley. The fact that the creature is somewhere loose on the BOTTLE SHIP is also similar to the concept of the first film.
  • The moment where the Mystery Creature assaults a pinned down Samus with it's barbed tail almost exactly mirrors a shot where the Queen Alien uses it's tail to attack Ripley at the end of Aliens.
  • Samus returning to the BOTTLE SHIP before it is destroyed to recover something important (in her case, Adam's helmet) is similar to Ripley returning to the hive to rescue Newt in Aliens.
  • Samus escaping with Adam's helmet is also similar to Ripley escaping with Jones, her cat.
  • Samus has posttraumatic stress disorder, a result of Ridley. This is similar to Ripley being traumatized by the Alien in Aliens. However, both are able to overcome their fears and defeat their foes.
  • Before the Brug Mass battle, one of the soldiers says "They're coming out of the walls!" This is also a line from the hive scene in Aliens.
  • MB and Madeline Bergman flee from Samus out of fear, similar to Newt, another survivor.
  • Samus discovering Adam was the one credited as the creator of the report for Project Metroid Warriors is similar to Ripley discovering, in Aliens, that Burke ordered the colonists to investigate The Derelict without warning them.
  • The scene where the Queen Metroid emerges from blast doors is similar to another scene in Aliens, where the Queen Alien exits a lift after being able to operate it.
  • Samus when discovering the Queen Metroid and her offspring in the climax tilts her head with an annoyed expression in a similar manner to Ripley when she, while escaping with Newt, discovered both the Queen Xenomorph and that one of her eggs was hatching in the climax to Aliens.
  • The Queen Metroid seems to have strong empathetic emotions towards her babies, as she will stomp on the ground and send a harmless shockwave to break through the ice freezing them. She also screams in agony and anguish when six of them are killed. This is similar to the Alien Queen in Aliens, who was extremely protective of her offspring, to the extent that she screamed in rage when Ripley burned her offspring alive when hatching in the sequel.
  • Ridley has 3 stages in his life cycle, much like Aliens have a three-stage lifecycle excluding the queen: Facehugger, Chestburster and adult form.
  • The Holographic Generator technology creates an artificial environment. A similar technology is seen in a deleted scene in Aliens.
  • Sector Zero detaches from the BOTTLE SHIP by having clamps holding it release, before the sector floats off into space and explodes. The Narcissus escape shuttle also does this at the end of Alien.
  • Samus awakens in a hospital after having nightmares of Mother Brain annihilating the baby, and gives a report, before responding to a distress signal, similar to Ripley in Aliens.
  • James Pierce's death is similar to Burke's in Aliens.
  • The Lusitania is similar in design to the Nostromo, Ripley's ship in Alien. Both are smaller transport ships attached to a much larger drive unit.

Metroid: Samus Returns[]

  • The game's logo is formatted similarly to that of Aliens.
  • The Zeta Metroid's physical similarities to the Xenomorphs in the original game are further highlighted here, not only having a redesign that is even closer to Xenomorphs than before, but also having its introduction to Samus being taken directly from Alien, where it drools on Samus and then lowers its tail before dropping to the ground.
  • The Metroid Detector now makes a beeping sound when Samus is close to a Metroid, similar to the Motion Trackers used by characters in the Alien films. The beeping gets slower or faster depending on how close Samus is.
  • Near the end of Area 8, a cutscene occurs where Samus's Metroid Detector goes haywire. This also happens with the Motion Trackers when Alien characters are near the creatures' hives.
    • In addition, the earlier implication that the Queen Metroid was roaring in fury over the deaths of her offspring is reinforced in this game, where she emits a loud roar immediately after Samus kills the last Metroid larva (originally, her roars were heard only after entering the room immediately above her boss chambers), similar to how the Queen Alien is implied to be extremely protective of her offspring.
  • Samus Returns (a remake of Metroid II) adds an epilogue to the game, where Samus and the baby are ambushed by Proteus Ridley as they are returning to her Gunship. A battle ensues between Samus and Ridley as she defends her new "child", similar to the battle between Ripley and the Queen at the end of Aliens.
  • The Metroid webs in this game, as well as their altering the environment when a Metroid is nearby, is similar to another element in the Alien franchise, in particular the Xenomorphs' altering of LV-426 in Aliens.

Metroid Dread[]

  • Elements of the game's plot, including initial investigations into whether the X had survived only for it to become very apparent that they had, resembles the premise to Aliens regarding the Space Marines and Ripley's investigation of a space colony.
  • The E.M.M.I.'s proclivity for crawling through vents and along walls and ceilings to hunt their prey is evocative of the Xenomorphs. In addition the E.M.M.I. kill Samus by stabbing her with a weapon in their mechanical heads, much like a Xenomorph's nested mouth.
  • During the final battle Raven Beak reveals his plans to clone Samus to get his hands on Metroid DNA, mirroring the plot of Alien Resurrection when the Weyland-Yutani Corporation cloned Ripley in order to extract Xenomorph DNA.

Super Smash Bros. Ultimate[]

  • When announcing the Metroid Mania Spirit event, the tweet from Nintendo of Europe announcing the event says at one point "Check your Spirit Board, because #Metroid characters are coming out of the walls!",[6] referring to an event that occurred in Aliens.

A Piercing Screech[]

  • Ridley's methods of dispatching Mega Man and Mario were reminiscent of the Xenomorphs in the Alien franchise. In particular, Ridley's method of impaling Mega Man with his tail resembles how the Alien Queen tore apart the android Bishop in the climax of Aliens.
  • Additionally, Ridley looks much like a xenomorph, with the head shape, exoskeleton and tail spike shape strongly resembles a xenomorph, or even more the Covenant praetomorph.
