The Metroid universe (メトロイド, Metroid) refers to the Smash Bros. series' collection of characters, stages, and properties that hail from Nintendo's famous Metroid series of science-fiction adventure games. It is one of the company's most successful franchises. The series has had eleven official games released thus far, with most of them being near-universally praised by critics and gamers alike. The series also has a compilation (Metroid Prime Trilogy) and two enhanced remakes (New Play Control! Metroid Prime and New Play Control! Metroid Prime 2: Echoes). The series revolves around the space-faring bounty-hunting exploits of a woman named Samus Aran.

Franchise description

After the perfect success of Super Mario Bros. and The Legend of Zelda for the Famicom/NES, Nintendo began work on an action game inspired by Ridley Scott's 1979 horror film Alien, Metroid. Nintendo set the game in the labyrinthine, subterranean cave network of a science-fiction alien planet to help impress a feeling of desperation and solitude on the player, and attempted to set the game apart from other games by making it a nonlinear adventure-based game that required exploration and backtracking. Like Zelda, Metroid helped pioneer the concept of acquiring permanent tools during the quest that would open up the way forward once the player returned to earlier areas. Metroid was also one of the first games to contain multiple endings, which were awarded based on how fast the game was completed; this had a hand in popularizing the concept of the "speedrun". Finally, Metroid was one of the first video games to feature a female protagonist - and this was initially presented to the gaming public as a concealed secret until the game was beaten in a fast-enough time.

For all these reasons and more, the August 1987 release of Metroid for the NES was another revolutionary and enormously successful release for Nintendo. Metroid had a palpable effect on the future of the video game industry, integrating what was technically several styles of gameplay that had already revolutionized the industry on separate prior occasions into a new formula that was married with a foreboding atmosphere. The revelation that the player-character, Samus Aran - appearing as a suited, mechanized soldier that the instruction manual referred to with masculine pronouns - was a woman underneath the armor plating was lauded as innovative for blowing away established norms of females in video games (like the damsels in distress in Mario and Zelda). Many retrospectives, however, find faults with some of the original game's design and layout in comparison to modern action-adventure standards, and these shortcomings were only partially addressed in the first sequel, Metroid II: Return of Samus, released for Game Boy in November 1991.

But by far the most significant evolution of the Metroid formula was the seminal Super Metroid, released on the SNES in April 1994. With vastly refined combat, exploration mechanics, world design, and even dialogue-free storytelling, the game garnered universal acclaim and is often labeled by official publications as one of the best video games ever made. The greatest irony is that the American and PAL versions of Super Metroid sold well as a result of aggressive marketing by Nintendo that was spurred on by the game's poor sales in Japan. Analysts proclaim that the Japanese release of Super Metroid was poorly timed, not only because of more commercially successful games being released at the time like Donkey Kong Country, but because of the launches of the next-generation systems Sony Playstation and Sega Saturn. This was a big contributing factor to what became a now-legendary eight-year hiatus for the series, which remained dormant despite Samus' appearance in Super Smash Bros. on the Nintendo 64, and Nintendo mentioning the possibility of a N64 installment which had never entered production.

The rebirth of the Metroid franchise at the end of 2002 was arguably one of the most daring and ambitious for any video game series; two completely separate, high-profile Metroid titles were released on the same day in the Americas, on November 17, 2002. Metroid Fusion, for the Game Boy Advance, was an all-new adventure based on the familiar two-dimensional formula of Super Metroid, but more noteworthy by far was Metroid Prime for the GameCube, the series' inaugural transition into three dimensions, which was highly controversial prior to release. Not only was it being developed by a then-unknown company in the United States, the Texas-based Retro Studios, but its presentation as a first-person shooter led to accusations of being a complete departure from the Metroid fabric. The released product allayed these concerns, to say the least; Metroid Prime garnered extremely enthusiastic acclaim for managing the task of faithfully transplanting the classic formula into three dimensions and using the first-person perspective to its advantage, and became one of the GameCube's bestselling titles.

Samus's Zero Suit, worn beneath her Power Suit, was introduced in Zero Mission and replaced previous depictions of unsuited Samus. Trophy of Power Suit Samus from Brawl.

The Metroid franchise settled into a more regular release schedule following Prime and Fusion. Metroid: Zero Mission, for the Game Boy Advance in February 2004, was a retelling of the original Metroid in yet another new title structured in the design style introduced by Super Metroid. While the original title allowed Samus to be playable without her armor using a cheat code, Zero Mission established Samus' abilities when outside of the Power Suit, making Samus playable in the new "Zero Suit" as part of the narrative. Metroid Prime 2: Echoes, for the GameCube in November 2004, was a Prime follow-up that changed several concepts and was tuned to a much higher level of difficulty. Metroid Prime Hunters was an ambitious effort to present the graphically intensive Metroid Prime first-person formula on the restrictive hardware of the Nintendo DS in March 2006. The Metroid Prime subseries concluded temporarily with the August 2007 release of Metroid Prime 3: Corruption for the Wii. The final chapter in the trilogy, the game introduced immersive motion controls to the series for controlling Samus and aiming her weapons, which were carried over to the Wii rereleases of the first two Prime games (all three games were later bundled as the limited-edition Metroid Prime Trilogy compilation for Wii).

After the conclusion of the Prime trilogy, Metroid: Other M was introduced in August 2010 for the Wii, developed by Team Ninja of Ninja Gaiden fame. Its new third-person action-adventure gameplay aspects were generally well-received; however, some reviewers criticized its approach to characterizing Samus, the voice acting and dialogue (with the English dub directed by the non-English-speaking Sakamoto), and the game's methods of telling a cutscene-heavy story, with the aforementioned elements causing a high degree of fan controversy and backlash. Thus, Other M sold significantly less than most previous console entries in the series outside of Japan, and marked the beginning of a second hiatus for the franchise.

During the Nintendo Digital Event at E3 2015, a new game in the series, Metroid Prime: Federation Force, was announced for the Nintendo 3DS and is a spin-off of the Metroid Prime series, with a 2016 release. The game is a co-op first person shooter, where the player assumes the role of a Galactic Federation Marine, featuring gameplay elements similar to that of Metroid Prime Hunters. Much like Other M before it, the game was met with a highly polarized reception for its graphical style, heavily reduced focus on Samus, focus on FPS combat over exploration, and its overall departure from the series' general style. Further criticism was aimed at the fact that the first Metroid game announced after the franchise's 5-year hiatus was a spin-off title.

With the controversy surrounding both Other M and Federation Force, as well as the five-year hiatus between them, the early-to-mid 2010s marked a period of uncertainty surrounding the state of the Metroid series. However, two new Metroid games were announced during E3 2017 - Metroid Prime 4 for the Nintendo Switch, and Samus Returns, an enhanced remake of Return of Samus, for the 3DS. The reveal of these two games marked the true end of the main series' hiatus, and, together with a new sub-line of Metroid amiibo, signaled the return of Metroid as one of Nintendo's flagship franchises.

Overall, the Metroid series is often held up as one of Nintendo's greatest classic franchises and maintains a dedicated fanbase, particularly in the West. Super Metroid and the Metroid Prime trilogy in particular have garnered significant praise from fans and reviewers. Samus herself, while not achieving the same level of recognition as Mario or Link, is widely praised as one of Nintendo's most iconic heroines and a groundbreaking example of proactive female protagonists in gaming.

The Metroid series stars Samus Aran, a hardened, one-of-a-kind professional bounty hunter raised by a now-extinct race of bird-like humanoids named the Chozo and sporting a powered suit imbued with fantastic Chozo technology. With an arm-grafted cannon that can shoot a variety of projectiles seemingly without limit, and a suit function that affords Samus the seemingly superhuman ability to transform into a perfectly spherical metal ball that can self-navigate tight quarters, Samus is regularly called upon by the primary known sovereign government of the Metroid setting, the Galactic Federation, to go on infiltration missions into planets and compounds occupied by races of alien Space Pirates. The series' namesake is a floating, jellyfish-like lifeform called a Metroid, which has the seemingly supernatural ability to siphon life energy out of its victims; Space Pirates seek to breed and harness these creatures, so it is up to Samus, seemingly the only individual with the upgradeable weaponry capable of killing them, to explore Space Pirate-occupied worlds and destroy their operations down to the core. Each primary Metroid title adds to a chronology of canonical games, which is laid out below:

• Metroid / Metroid: Zero Mission: Samus' first mission is is to infiltrate the formerly Chozo-inhabited planet Zebes, since overtaken by Space Pirates, and destroy their standing forces and their stable of Metroids. Along the way, Samus battles the foremost "enforcers" of the Space Pirates - the colossal reptilian Kraid and the dragon-like Ridley (likely named after Alien director Ridley Scott) - and ends up battling the organic artificial intelligence helping dictate Pirate operations, Mother Brain. Immediately after a seemingly successful mission, however, Samus runs into some bad luck during her escape attempt, and is forced to find a way off the planet in just a body suit while equipped with a stun gun. After successfully escaping, Samus is able to harness the power of the ancient Legendary Power Suit (which more closely resembles her usual design) by proving herself at the Chozodia temple.

• Metroid Prime: Samus tracks remnants of the Space Pirates to another outpost on the planet Tallon IV, and she discovers that they are experimenting on augmenting their capacity for warfare with a mysterious mutagenic substance called Phazon, which was brought to the planet by an enigmatic meteor strike long ago. She destroys the Space Pirates' research and standing forces once again, but along the way inadvertently allows for the incidental birth of a dark opposite to herself, the sentient Phazon entity Dark Samus.

• Metroid Prime Hunters: When the Galactic Federation receives a mysterious telepathic message that the key to the "ultimate power" resides in the Alimbic star system, Samus is sent to investigate and possibly retrieve it, but six other rival bounty hunters from different alien species compete for the same goal.

• Metroid Prime 2: Echoes: The Galactic Federation loses contact with a federation marine vessel that engages a Space Pirate vessel near another Space Pirate outpost planet named Aether, and Samus is sent to investigate. She discovers the planet was struck by a similar Phazon meteor in its past, which has split the planet into light and dark dimensions. Samus must not only separately contend with the Space Pirates and Dark Samus itself, but even more threatening shadow creatures from the dark dimension, the Ing.

• Metroid Prime 3: Corruption: With the Space Pirates' Phazon-based operations now in disarray from Samus' meddling, the Space Pirates turn to Dark Samus for aid, and allow themselves to get indoctrinated by the entity. Dark Samus seeks to corrupt the galaxy with Phazon and has the Space Pirates launch simultaneous attacks on separate Federation planets, and Samus herself gets her suit corrupted during the struggle. Granted new technology that allows herself to harness her own suit's Phazon corruption, Samus goes on a planet-hopping quest to end the Phazon menace forever, even as her fellow bounty hunters become corrupted and turn against her. Along the way, Samus realizes the truth about the origin and nature of the Phazon-filled "living-meteors" called Leviathians.

• Metroid Prime: Federation Force: After Samus' elimination of the Phazon menace, the Space Pirates continue to serve as a threat in their own right. The Galactic Federation therefore initiates "Operation Golem" and deploys mech suits, controlled by elite Galactic Marines, in order to eliminate the Pirates. A significant Space Pirate presence is detected in the Bermuda System and the Marines are sent to eradicate them, with some assistance from Samus.

• Metroid II: Return of Samus / Metroid: Samus Returns: The Galactic Federation has deemed the Metroid species too great a threat to be allowed to live, and so tasks Samus to cull every individual specimen off the surface of the Metroid homeworld, SR388. Samus destroys Metroids that have matured into advanced, more monstrous forms, and squares off against the Metroid Queen itself, but at the end of her mission, she spares a lone hatchling and donates it to the Federation's research division.

• Super Metroid: However, a revived Ridley raids the research division and takes back the hatchling by force, and Samus returns to Zebes on another mission to thwart the Space Pirates' last efforts to preserve and harness the species. She infiltrates the Space Pirates' reconstructed subterranean base on Zebes, and discovers and once again battles each of her classic foes - Kraid, Ridley, and the Mother Brain - before detonating the entire planet and achieving the extinction of the Metroid species.

• Metroid: Other M: Samus follows a distress signal towards a "Bottle Ship" floating near a Federation vessel, and discovers some of her companions from her days in the Federation military, including commanding officer Adam Malkovich, on board in the middle of a mission he does not tell Samus about at first. After Adam begrudgingly allows her to cooperate with the platoon, they discover the first signs of a darker side to the Federation.

• Metroid Fusion: While leading scientists on a Federation-sanctioned survey across SR388, Samus is attacked by a native parasitic lifeform, the X Parasite, that was originally kept in check by its natural predator, the Metroids. Samus survives, but becomes permanently bound to a "fusion" form of her suit. The research station floating above the planet later becomes infested with X Parasites that mimic other organisms, and so Samus, whose new form is immune to the infestation, is sent on a mission by the Federation to fight and wipe out the creatures. Or at least, that is what Samus thinks her mission is strictly about...

In Super Smash Bros.

Despite there being no Metroid game on the Nintendo 64, the Metroid franchise is represented as one of several "standard universes" found in Super Smash Bros.. There is a total of one character and one stage representing Metroid, both which focus on the original Metroid, and the recent Super Metroid. This game makes Samus's only appearance on the Nintendo 64.

Character

• 
  Samus: A bounty hunter in a technologically advanced and flexible power suit, Samus Aran is an orphan from a Space Pirate attack. She was harbored by the benevolent Chozo race at a young age and infused with their heritage and technology, and she now serves the Galactic Federation as pretty much a one-woman army against the menace of the Space Pirates and their attempts to use the life-stealing Metroids to conquer the universe. In Smash 64, Samus appears as a starter playable character. Her neutral special is the Charge Shot, a chargeable ball of energy that Samus shoots out of her arm cannon. Her up special is the iconic Screw Attack first appearing in the original Metroid. Samus's down special is her Bomb from the original Metroid. This moves makes Samus turn into Morph Ball mode and lay a bomb, which will explode either after a set time period or upon contact with a character.

Stage

• 
  Planet Zebes: This stage is designed to resemble the general environment and hazards of the caverns of the titular planet that Metroid and Super Metroid take place in. It is a big platform with three platforms above it, and one on the right moving vertically. The stage features an ocean of acid that periodically rises up and submerges the lower portion of the stage. Touching the acid will damage a character and send them flying upward. Due to the acid, it is impossible, under normal conditions, to die by falling below the main platform.

Music

• 8: A remix of the Brinstar music from the original Metroid for NES. It is heard on Planet Zebes.
• 18: The victory fanfare of Samus is an orchestration of the music heard when Samus finds a new item or power-up in general Metroid games.

In Super Smash Bros. Melee

Much like the Smash 64, there was no new Metroid game released before Melee, so the majority of Metroid representation is still from the original Metroid and Super Metroid. This game features much more Metroid content than Smash 64, including one returning character, two new stages, and a handful of trophies. This game also introduces the first Metroid item.

Character

• 
  Samus: Samus returns as a starter character, and as the only Metroid character, probably because of the nature of Metroid games and how they do not seem to feature notable supporting characters. As with all returning characters, Samus gained a new side special, being her Missile attack from Super Metroid. She points her arm cannon in front of her, and shoots either a Homing Missile or a Super Missile depending on how the control stick is tapped. Samus is considered as the one of the two most buffed characters from Smash 64.

Stages

• 
  Planet Zebes: Brinstar: This stage is the spiritual successor to the original Planet Zebes stage, and it features a nearly identical layout; aside from the visuals, the only real difference to this stage is that parts of the stage can be damaged by players attacks, and destroying these can cause the elevated platforms to rise upwards to steep angles and the big lower platform to break apart into two. A large creature that is possibly the Mother Brain appears in the background, shaking whenever the lava comes up to it.
• 
  Planet Zebes: Brinstar Depths: This stage appears to be loosely based on Kraid's encounter in Super Metroid. A difficult stage to keep on top of, this is essentially a giant, craggy, circular mass of rock that floats above lava. The lava on the bottom of the screen does not damage the player like other Metroid stages, as it is merely a background effect symbolizing the blast line. The stage is routinely rotated by the gigantic alien monster Kraid in the background. It is impossible to grab onto any ledge in this stage.

Item

• Screw Attack: An upgrade that Samus can obtain ever since the original Metroid. It allows Samus to somersault into enemies in the, killing many instantly. In Melee, a character can pick up this item and perform the same action once they jump, similar to Samus's own up special. The character can also hurl it at an opponent and the opponent will automatically jump up whirling.

Music

• 7: Brinstar: A medley of three classic tunes from the original Metroid. First plays a techno remix of the first "Brinstar" area music. It is then followed by the short "game start" tune one hears whenever resuming a game file. Finally, a remix of the title screen plays before looping back into the first track. This is heard in the stage Brinstar, and acts as one of Samus's credits theme.
• 8: Brinstar Depths: A synth, techno remix of area music heard later on in the original Metroid, where Samus is particularly close to her encounter with Kraid. A bridge section consists of the short tune played in item rooms in the original Metroid. This is heard in the stage Brinstar Depths, and acts as one of Samus's credits theme.
• 41: Samus's Victory: The victory fanfare of Samus is an orchestration of the music heard when Samus finds a new item or power-up in general Metroid games.

• Samus Aran [Smash]

In Super Smash Bros. Brawl

A fairly-decent amount of content from the Metroid franchise appears in Super Smash Bros. Brawl.

Characters

• 
  Samus: Shown by trailers as a returning character for Brawl, Samus Aran has been visually touched up to look like her more detailed incarnation in the final sequence of Metroid: Zero Mission, but otherwise apparently retaining her gameplay. Her Final Smash, the Zero Laser, is a huge beam that literally blows off her own armor to become a pile of throwable Power Suit Pieces and renders her as a new playable character, Zero Suit Samus.
• 
  Zero Suit Samus: The suitless version of Samus from Metroid: Zero Mission is playable via Samus' Final Smash. She fights acrobatically and carries a projectile attack in the form of her handheld Paralyzer gun, which she also uses as the basis for her Plasma Whip and Plasma Wire special attacks, both of which can be used for tether recovery. Zero Suit Samus' Final Smash involves a huge, blinding ball of light forming around her, returning her to status with the power suit.

On the final character select screen (after all characters are unlocked), Samus shares the fourth column with fellow Famicom/NES-originated characters Ice Climbers, R.O.B., and Pit.

Bosses

• 
  Ridley: Samus's arch enemy Ridley makes an appearance in the Subspace Emissary as a boss that Samus and Pikachu encounter in a facility on the Island of Ancients shortly after Samus regains her Power Suit. It would seem he is working for the Subspace Army, but no information really exists on his storyline importance.
• 
  Meta Ridley: Later in the game, when a slew of characters are escaping from the self-destructing Subspace Bomb Factory on Captain Falcon's Falcon Flyer, a rebuilt Ridley in the form as seen in Metroid Prime appears. While he is canonically just a modified Ridley, the fight plays out nothing like the previous Ridley fight. It is worth noting that Metroid is the only represented franchise to feature more than one boss fight.

Assist Trophy

• Metroid: A Metroid latches its body on a character's head and starts draining their health, increasing the character's damage percentage in the process.

Stage

• 
  Norfair: A new stage set in the fiery depths of Zebes, this stage, like previous Metroid stages, features rising lava. In addition to this, lava can come from the sides of the screens too, as well as in an enormous wave from the background that forces players to fight to stay inside a temporary safe zone to avoid damage.
• 
  Frigate Orpheon: Set in the opening area of the first Metroid Prime, which contains the Parasite Queen, this stage has an interesting twist. When the warning siren sounds, the stage flips, and what was once above the players becomes the new platforms to fight on.
• 
  Melee Stages: Brinstar: One of the few stages to return from the previous game, it is mostly unchanged from Melee.

Music

See List of SSBB Music (Metroid series).

• Main Theme (Metroid) - A rock styled remix of the Brinstar theme from the first Metroid title. Aside from the vocals at the beginning of the track, this is taken almost directly from Metroid Prime Pinball, with the insertion of some extra instruments and the addition of the original Brinstar NES-like remix. It is used on the Norfair stage.
• Ending (Metroid) - An orchestrated version of the credits theme used in both the original Metroid and its remake, Metroid Zero Mission. It is used on the Norfair stage. This song is also played during both Samus and Zero Suit Samus' Classic Mode credits.
• Norfair - A quirky remix of the lesser-known Norfair theme from the original Metroid game. It is the theme of the Norfair stage.
• Theme of Samus Aran, Space Warrior - An orchestration of the credits theme of the SNES hit, Super Metroid. It is used on the Norfair stage.
• Vs. Ridley - A completely redone version of Ridley's theme that is featured in several Metroid games and originated in Super Metroid. It is used on the Frigate Orpheon stage.
• Vs. Parasite Queen - Taken directly from Metroid Prime, this was the track that played when Samus fought the Parasite Queen during the opening section of the game. It is used on the Frigate Orpheon stage.
• Opening/Menu (Metroid Prime) - A medley of two tracks from Metroid Prime--the title screen and the credits theme (which itself was an extension of the menu theme). With the exception of the vocals at the beginning, the title screen theme is taken directly from the game, while the credits theme is arranged. It is the theme of the Frigate Orpheon stage.
• Sector 1 - An orchestrated version of the background music of the first mission in Sector 1 in Metroid Fusion. It is used on the Frigate Orpheon stage.
• Vs. Meta Ridley - Taken directly from Metroid Prime, this was the background music that played during the fight against Meta Ridley. This same, unaltered track was also used in Metroid Prime 3: Corruption. It is used on the Frigate Orpheon stage.
• Multiplayer (Metroid Prime 2) - A track taken directly from the multiplayer mode of Metroid Prime 2: Echoes, which itself was a techno remix of the Brinstar background music from Super Metroid. It is used on the Frigate Orpheon stage.
• Brinstar (Melee) - Taken directly from Melee. It is used on the Brinstar stage.
• Brinstar Depths (Melee) - Taken directly from Melee. It is used on the Brinstar stage.
• Samus' victory theme - The "got item" fanfare featured in every single Metroid game to date, except Metroid: Other M.

Games with elements in Smash Bros. games

Metroid

Main character and Bounty Hunter Samus Aran is playable in all four Super Smash Bros. games and the main enemies from this game, Metroids, appear as Assist Trophies in Super Smash Bros. Brawl. Planet Zebes is a stage in Super Smash Bros., and its sub-areas Brinstar, and Brinstar Depths are stages in Super Smash Bros. Melee and Super Smash Bros. 4. The final boss, Mother Brain, appears as an Assist Trophy in SSB4. Norfair appears as a stage in Brawl with the returning Brinstar, although Brinstar Depths is absent. The boss Ridley is featured as a background character in Super Smash Bros., a trophy in both Melee and Brawl, is present in Melee 's introduction, and is a boss in Brawl. A Waver enemy is also in Zebes' background. Kraid also originates from Metroid as a trophy and stage element in Melee. Samus' Screw Attack, Missile and Bombs originate from this game. As for her normal moveset, her dash attack comes from the Speed Boost power-up acquired in most of her side-scrolling games.

Super Metroid

Samus and Ridley take their Super Smash Bros. appearances from this game, with Ridley's appearance in the background of Planet Zebes in Super Smash Bros. being based on his sprites from this game. Samus emerges from a Super Metroid-style Save Station when entering battle. A clip of the introduction features Samus and Ridley fighting in a 3-D re-enactment of their fight on Ceres at the beginning of Super Metroid, with Ridley holding the baby in its talons. A Chozo Statue that stands up and walks around in the background of the Brinstar stage is based on the Torizo enemies from Super. Kraid also takes his Super appearance in Melee. The Brinstar Escape Shaft is modeled remarkably after Super, particularly resembling the platform-filled shaft Samus had to escape through in Super and the original Metroid, going from a cave-inspired scenery to a mechanical elevator room.

Metroid Fusion

One of Samus' alternate costumes in Brawl and SSB4 is a palette swap based on the Fusion Suit. Additionally, the Fusion Suit appears as a trophy in Brawl.

Metroid Prime

The first location the player visits in the game, Frigate Orpheon, is a stage in Super Smash Bros. Brawl. Also, the Parasite Queen, a boss from the game, appears as a background character.

Meta Ridley, the cybernetic version of Ridley in the Subspace Emissary, first appeared in this game.

The credits/main menu theme is an available song in the Frigate Orpheon stage. The Meta Ridley battle theme is also available on the same stage.

Trophies from the game include the Sheegoth, and the creature and final boss of the game, the Metroid Prime, with its exoskeleton and core forms being made into separate trophies.

Metroid: Zero Mission

Zero Suit Samus' appearances in Brawl and SSB4 originate from this game; after defeating Mother Brain, Samus loses her Power Suit, and escape while fending off Space Pirates while wearing a body suit, now known as her "Zero Suit", and stunning them with her emergency pistol, now known as the "Paralyzer."

Metroid Prime 2: Echoes

One of Samus' alternate costumes in Brawl and SSB4 is a palette swap based on the Dark Suit. Additionally, the Dark Suit appears as a trophy in Brawl and SSB4. One of Samus' alternate costumes in SSB4 is a palette swap based on the Light Suit.

Metroid Prime 3: Corruption

Dark Samus's design comes from this game. Her moves as an Assist trophy are based on her boss fight.

Metroid Prime Hunters

All bounty hunters from this game appear as trophies in Brawl. The song "Psycho Bits" which plays when battling enemies of the same name appears on the Pyrosphere stage

Metroid: Other M

Samus and Zero Suit Samus' designs in SSB4 are heavily derived from this game, and the Pyrosphere appears as a stage along with the Ridley clone in Super Smash Bros. for Wii U. FG II-Grahams, Joulions, and Zeros appear as enemies on the Pyrosphere stage.
