Boxing Ring Title: Leader of Star Fox

Theme Song: Main Theme – Star Fox

Fox McCloud is the main protagonist of the Star Fox series, and is the leader of a band of mercenaries called Team Star Fox.

In the original "Star Fox" game released for SNES, Fox and his team - consisting of his best friend Slippy, the hotheaded Falco, and the experienced pilot Peppy - were given a mission from General Pepper to stop the evil ambitious of a rogue scientist named Andross. Fox was eager to answer the call, especially since Andross was responsible for the disappearance of his father. To help them get to Andross's base, which was located on the planet Venom, General Pepper gave Fox and his team experimental flying vehicles called Arwings to assist them in their mission.

Their missions would see them travel to various planets, tackling Andross's forces as they tried to make it to the planet Venom. Upon arriving, Fox would fly in to face Andross alone, where he discovered that Andross had uploaded his mind into a cube, which would go into a weird robotic mask looking thing. Upon taking enough damage, the face would reconstruct itself to resemble a bull, and would constantly attack Fox. Despite the constant projectile fire, Fox manages to defeat Andross, though his defeat triggers his base's self destruction. Luckily, Fox manages to escape back to his teammates. They then head back to Corneria to collect their reward.

The game's story would be followed up in "Star Fox 2", though it would take about 22 years for it to be officially released. Notably, Fox would add two new members to his team - Miyu the Lynx and Fay the Dog - who have only ever appeared in this game.

Andross has survived his previous defeat, and has rebuilt his army, even hiring the notorious Star Wolf to assist him. Along with his new stronghold called Astropolis, Andross launches an all-out assault to conquer the Lylat System. General Pepper once again hires Star Fox to not only stop Andross's schemes, but to also defend Corneria.

The series would get its first reboot with "Star Fox 64." While some elements from the SNES game were kept, others were changed, such as Fox going from 25 years old to 18. The game would also get a remake for the Nintendo 3DS called "Star Fox 64 3D".

As told in the game's intro, Fox's father James McCloud was the head of the original Team Star Fox. The members consisted of him, Peppy Hare, and Pigma Dengar. James and his team were constantly out on missions while Fox was attending a pilot academy. One day, James and his team were sent out to deal with Andross, an insane scientist who was slowly rising in power. Unbeknownst to everyone, Pigma had betrayed James's team and helped Andross set up an ambush on Star Fox. The only survivor of this disaster was Peppy Hare, who was given the heavy burden of informing Fox of what happened.

Now being tasked to take on the burden of leadership, Fox would form a new Star Fox team. Along with himself as leader, he would recruit his friend Slippy as his mechanic, the hotheaded flying ace Falco, the wise and experienced Peppy Hare, and a friendly AI called ROB 64. And with that, they take off as a mercenary-for-hire group, working to improve the safety of Corneria.

When the mad scientist, Andross, began his assault and conquered planet after planet, General Pepper called in Star Fox to not only stop Andross's invasion of Corneria, but also free the other captured planets and stop Andross once and for all. Fox eagerly agreed to do so, and thus his adventure begins.

They are many paths Fox can take throughout the adventure, which leads into different planets and scenarios. For example, Fox can potentially meet up with an old friend of his, Bill Grey, who is fighting off Andross's forces at Planet Katina. If Fox is success in helping him, Bill will show up at Sector X to repay Fox. Fox can also potentially encounter Team Star Wolf on three of the planets in the story. Star Wolf is a mercenary group hired by Andross to fight off the Corneria army, and they serve as personal enemies to Team Star Fox. Star Wolf's leader, Wolf O'Donnel, serves as Fox's main enemy.

Arriving at Venom after dealing with the crisis at Area 6, Star Fox manage to arrive at Andross's front door without him even knowing! Before they begin their assault, Star Wolf ambushes them in their brand new Wolfen II space ships in a last ditch effort to stop them. Star Fox manages to defeat them, after which Fox decides to face Andross alone.

Flying deep into Venom's base, Fox confronts the mad scientist, who is now a giant floating head with arms. Fox begins to fire away at Andross's face and arms while trying to avoid Andross's attacks. Fox manages to emerge victorious as Andross explodes...

Which reveals his true form: a brain with two eyes! Switching to All-Range Mode, Fox flies around the battle arena, targeting Andross's eyes. Once they're taken care of, Fox focuses on attacking the medulla of Andross's brain. Once Andross has taken enough blows, he decides to blow up the entire base, taking Fox with him. Just as hope seems lost, Fox's father suddenly shows up to lead Fox to safety.

As Fox emerges from Andross's exploding base, he's greeted by the rest of his team, happy to see that he's alive! However, Fox is somewhat solemn, wondering if that was truly his father he saw, or some hallucination. Regardless, he and the team head back to Corneria to collect their reward from General Pepper. Pepper offers them a position to join the Corneria military, but Fox refuses and heads off to new adventures with his team.

4 years later, Falco would leave Star Fox after he and Fox had an argument, which was explored in the manga "Star Fox: Farewell Beloved Falco".

In "Star Fox Adventures", which takes place another 4 years after Farewell Beloved Falco, Star Fox was looking to earn some money to repair the Great Fox. As they began to approach Dinosaur Planet, General Pepper contacted them, telling them that chunks of the planet are drafting apart, and if this continues, Dinosaur Planet could explode and devastate the Lylat System. If Fox could stop it, he would forward him a huge sum of money. Fox agrees, and heads down to the planet to try and save it.

As Fox heads to the Thorntail tribe - during which he finds a staff that belongs to a blue fox girl named Krystal - he finds out that the Queen's son, Tricky the triceratops, had been captured by the Snowhorn Tribe. Upon rescuing him, Fox would then save Tricky's mom by finding some White GrubTub to cure her of her poisoning. Queen Earthwalker then explains that the reason the planet is falling apart is because of General Scales, ruler of the Sharpclaw tribe. He's always wanted to rule Dinosaur Planet, and has tried to invade the Karzao Palace for some time. Normally, the Thorntail tribe has always been able to stop him, but thanks to new powers he's obtained, he managed to defeat them and enter the palace.Scales then broke the seals of the Force Point Temples to obtain the four Spellstones. Without the Spellstones, the planet will break apart, due to a massive amount of magical energy contained within it.

Fox is then tasked with retrieving the stones with the help of Prince Tricky, who's breath would be able to reactivate the Spellstones, Thus, the adventure truly begins, which takes Fox and Tricky to various areas on the planet. Some time after they obtained the first Spellstone, Fox meets the Krazoa God, who informs Fox that another girl named Krystal had attempted his trials before getting captured by General Scales, and that the only way to save her was to complete the trials in her steed to collect the other 5 Krazoa Spirits and take them to the Krazoa Palace, where Krystal was being held.

At the end of the game, Fox and Tricky manage to retrieve the four Spellstones and obtain the five other Krazoa Spirits. Arriving back at the Krazoa Palace, General Scales ambushed Fox, though the battle was short-lived as a mysterious voice ordered Scales to release his Krazoa Spirit to Fox. As Fox collects the final Krazoa Spirit, he notices that the mysterious voice sounds familiar, but can't place it. Regardless, he returns the final Krazoa Spirit and frees Krystal from her prison.

Just then, the head of a giant stone statue of the Krazoa God emerges, claiming that all must serve him now that he's reborn. Fox jumps into his Arwing to chase after it as it flies into space, where he finds out that the "Krazoa God" is nothing more than Andross, who wanted to use the Krazoa Spirits to revive himself! Getting into a massive battle, Fox would receive some unexpected assistance from Falco, and together they manage to defeat Andross once more.

With Andross gone, the Krazoa Spirits return to the Dinosaur Planet to keep its magic under control. Fox flies back to the planet and sees that the SharpClaw tribe are even celebrating Fox's victory over both Andross and their fallen Commander, Scales. Back on the ship, General Pepper gives Fox his full payment, and says that Tricky and his parents are grateful for Fox's assistant. Falco decides he wants to rejoin the team, and Krystal arrives as well to personally thank Fox, as well as join his team as a new member.

Taking place at least one year after the events of Star Fox Adventures, "Star Fox Assault" occurs. Fox and his team are initially called in to stop Andrew Oikonny, Andross's nephew, who was kicked out of Star Wolf 8 years ago. Andrew had begun to rebuild his uncle's empire, and was planning to launch an assault on the Lylat System once more. Team Star Fox had him on the run, only for a mysterious moth-like creature to arrive and destroy not only Andrew's ship, but also Andrew himself. At first Fox thought that maybe the mysterious alien was on their side, but that thought didn't last long when it turned to attack them! Fox and his team manage to defeat it and obtain its memory core before retreating back to the base.

Back at the base, Slippy's father, Beltino, told them that the mysterious alien was called an "Aparoid." The Cornerian Fleet encountered one of them 17 years ago, and it managed to wipe out the entire fleet by itself before going down. While they're trying to find out how to stop it from the memory core Fox obtained, research would go quicker if they could find an undamaged one. General Pepper than receives a distress signal located at Planet Katina, and Star Fox is sent out to investigate.

Once there, they find out that Pigma Dengar, a member of Star Wolf, was the one who sent the signal. After being saved, he "thanked" Fox by stealing the Memory Core Fox was about to grab. Fox and his team head off to Pigma's last known location, Sargasso Space Zone - an illegal hideout for criminals - to get the Memory Core back. After a fight with Star Wolf, Fox and his team learn that Wolf kicked Pigma out of the team some time ago. However, Panther - a new member to Star Wolf - revealed where he last heard Pigma went, and Star Fox heads off.

At Fichina, Slippy learns that the Aparoids are able to assimilate machinery. They also manage to find Pigma, only for him to escape and leave Star Fox to deal with the Aparoids. After which, they would chase Pigma down to the Meteor Belt, where they learn that the Memory Core Pigma stole has assimilated him, turning him into an Aparoid monstrosity! After defeating him, they learn from Krystal that the Aparoids have invaded Dinosaur Planet, and head there to stop it.

Once they take care of that, they learn from General Pepper that the Aparoids have invaded Corneria! As Fox heads alone to deal with the situation, he gets some unexpected help from Star Wolf. After that, it turns out that the Aparoids have infected General Pepper's flagship. Pepper begs Fox to kill him before the Aparoids assimilate him. Before Pepper was about to die, Peppy managed to rescue him by stabilizing his crash through the use of his own Arwing. With Corneria in ruins and Pepper in medical care, Beltino took over as commanding officer and revealed to Star Fox that his team had managed to discover the Aparoid Homeworld. Beltino was also working on making an anti-Aparoid device that, if fired on the Queen Aparoid, would wipe out the entire race!

Unfortunately, the Aparoids managed to learn of the Cornerian Army's plan and launched an assault on their temporary base, the Orbital Gate. Fox and his team, along with Star Wolf, would head off to deal with the Aparoids, even managing to stopping a missile assault that the Aparoids used as a desperation measure. With the Anti-Aparoid device complete, Star Fox heads off to the Aparoid Homeworld.

Just before Star Fox could enter the planet, a self-defense barrier activated, preventing entry. The Great Fox came under heavy attack. As a last ditch effort, Peppy and ROB 64 decide to sacrifice themselves by steering the Great Fox into the barrier, allowing Star Fox and Star Wolf to enter. Inside, they are ambushed by various Aparoids. To ensure the mission would go well, Star Wolf decide to hold them off while Fox and his team head off to the location of the Queen Aparoid.

When they discover the queen, she tries to tempt Fox into joining her by taking on the false identities of his closest ally General Pepper, and his father James McCloud. (oh, and Pigma too.) Although Fox is about to surrender, he remembers some words Wolf gave him earlier and regains his resolve. After a tough fight, they manage to fire the anti-Aparoid device into the Queen! However, she seems to be resisting it, and tries to run away so she can create a vaccine! Star Fox chase after her, and with a couple of blasts, manage to activate the anti-Aparoid device and wipe the entire Aparoid race from existence!

As Fox and his team fly through space, they manage to find Peppy and ROB 64 in an escape pod. Assuming that General Pepper and Star Wolf also managed to survive the ordeal, they all head for home.

In "Star Fox Command" Team Star Fox had disbanded. Fox and ROB 64 were the only members left. Krystal stayed with him the longest as they promised to be together forever, but Fox eventually pushed her away as he didn't want to see her get hurt in this dangerous line of work. Fox spent most of his time flying through space, pondering his life choices while tying up loose ends.

However, one day an evil group called the Anglar Armada arrived from the depths of Planet Venom's toxic ocean and began to terrorize Corneria. Fox decides to tackle the threat head on. Throughout the course of the game, the player can make choices that could result in Fox getting the team back together, or only some of them. All of this leads into 9 different endings.

In the ending "The Anglar Emperor" - which players will obtain on their first playthrough - Fox reunites his team and they manage to defeat the Anglars. However, Fox is still troubled by complicated feelings, resulting in Krystal leaving him to join with Star Wolf, leaving Fox alone and unloved.

In the ending "Fox & Krystal", things are similar to the previous ending, except that Fox has come to value friendship and love, which causes him to apologize to Krystal and strengthen their bond. Slippy's fiancee, Amanda, also decides to join the team. Looks like Team Star Fox is back, baby!

In "Good-bye Fox", after defeating the Anglers, Fox and the rest of the team vote to retire and disband Star Fox. After which Fox decides to settle down with Krystal. They have a son named Marcus, who follows in father's footsteps by leading the next generation of Team Star Fox. This new team consists of Marcus as the leader, Slippy's son, Peppy's granddaughter, and returning member Falco Lombardi as their experienced mentor.

In "The Curse of Pigma," Fox becomes depressed from Star Wolf stealing both the fame and Krystal from him. He's left in massive slump until Falco suggest that the two retire from being pilots and join the G-Zero Grand Prix, which gives Fox a new lease on life.

After which, the series would receive another reboot in "Star Fox Zero". It mostly follows the same story beats as "Star Fox 64" - James McCloud was the original leader of Star Fox, betrayed by Pigma, Peppy informs Fox who takes up the leader role - though some of the scenarios they take to stop Andross are a bit different.

Personality-wise, throughout the series Fox McCloud is characterized as a strong-minded and responsible leader, usually always seen with either a stoic look or a cocky expression. Though he tends to be a bit overconfident at times and tends to disregards rules and regulations, he is ultimately pure of heart, though he will occasionally fret and complain if he feels he isn't getting payed well enough.

In Super Smash Bros., Fox is deceptively quick and can quickly rack up damage on his foes! Even during the bleakest moments of a fight, never give up and trust your instincts! 

Special Moves 

Neutral Special: Blaster 

Fox pulls out his gun and fires a laser beam. By constantly pressing the Special button, Fox can rapid-fire the beams! However, the laser beams are incapable of making his opponent flinch, so Fox shouldn’t rely on it if they're close to him.

Inspired by the laser gun he wields in the multiplayer mode of “Star Fox 64”. The name for it, Blaster, was not used until “Star Fox Adventures”. 

Side Special: Fox Illusion

Fox stands still for half-a-second before boosting forward at incredible speeds! The move isn’t very strong, but those that get hit get sent flying upwards.

If Fox is on the ground and uses the move near a ledge, he'll halt his forward momentum so he won't fall off of it.

This move is original to Super Smash Bros., though it may be inspired by the Arwing's capability of flying at high speeds when using a warp in "Star Fox 64".  

Up Special: Fire Fox

Fox surrounds himself in flames. Anyone standing close to him will take damage from the flames. After a second, Fox fires himself off, engulfed in flames and flinging anyone away from him. Depending on which direction you’re holding will depend on where he fires himself, though the default is straight upwards if nothing is held.

This move is original to Super Smash Bros., though it’s possible that it's inspired by the scene of the Arwings entering a planet's atmosphere in "Star Fox 64". It could also be inspired by the pyrokinetic abilities of the Japanese myth, the Kitsune, a fox-like creature.

Much later in the series, “Star Fox 64 3D” would introduce a powerup in its multiplayer mode called the Firebird. When the player grabs the Firebird powerup, the pilot’s Arwing would surround itself in flames, allowing the user to ram into anyone and instantly defeat them. It may be a reference to the Fire Fox move. 

Down Special: Reflector 

Fox brings out his reflector, which surrounds him a hexagon energy shield. Any projectile tossed his way gets reflected back at the offender! Additionally, when you activate the move near a foe, the reflector will do some damage to the foe and fling them away.

This move is original to Super Smash Bros., though it may be inspired by how the Arwings can deflect enemy fire by doing a Barrel Roll.

According to Snake’s Codec Conversation in “Super Smash Bros. Brawl”, Fox’s friend Slippy is responsible for making the Reflector. The Reflector would make its first appearance in a Star Fox game in “Star Fox Zero”, though since all of the action takes place in the Arwings, it doesn’t see any use. 

Final Smash: Team Star Fox 

Fox shouts “It’s go time!” as a targeting reticle appears in front of him. Three Arwings – assumingly being flown by Falco, Slippy, and Peppy – fly towards it. Anyone that gets hit by the Arwings gets flung into space, where Fox, now in his own Arwing, joins up with the others. Fox then leads the charge while shouting “Star Fox-fire at will!!” as they blast away at the helpless foe(s).

If Wolf is part of the battle and the Arwings happen to hit him, Fox will shout “This is the end for you, Wolf!” instead.

Inspired by the main gameplay style in most of the Star Fox games, first introduced in "Star Fox" for the SNES. In those games, the player, who’s controlling Fox, flies the Arwing around various planets. They can also use the Arwing’s laser beams to fire at any obstacles and enemies that get in the way.

Additional Notes 

On the Corneria, Venom, and the Lylat Cruise stages, Fox can perform a special “Smash Taunt” by quickly tapping the “Down Taunt” button. Upon activating it, Fox will enter a crouch-like pose, during which he must not get attacked for a few seconds or else the it'll get cancelled.
After a few second pass, Fox will rise up and strike a pose, signaling the Smash Taunt was a success! Fox’s friends – Slippy (all stages), Falco (all stages), Peppy (all stages), and Krystal (Lylat Cruise only) – will then start commenting on the battle or the stage, or even something unrelated to what’s happening. Some members of Team Star Wolf will chime in during the Lylat Cruise “Smash Taunts” as well.
Fox can only perform a Smash Taunt once per battle, and only if Falco, Wolf, or another Fox haven't done one.

If Falco is present during a battle and Fox is the winner, Fox may say “Better luck next time, Falco.” instead of “This is Fox. Returning to base.” during this victory pose.

Out of all the characters, Fox is the one who has received entirely new voice clips in every installment throughout the Super Smash Bros. series.

Boxing Ring Title: Phazon Incarnate

Theme Song: Vs. Parasite Queen (Ultimate Remix)

Dark Samus is a major antagonist in three of the mainline installments of the Metroid Prime series. Sharing the physical appearance of Samus's Power Suit, Dark Samus is capable of performing Samus's abilities, in addition to her own unique skills. However, before she took on her iconic form, Dark Samus was originally a heavily mutated Metroid called "Metroid Prime."

Before the events of the game Metroid Prime, a Leviathan from the planet Phaaze landed on the planet Tallon IV, where it began to spread a highly toxic and mutagenic ooze called Phazon everywhere. However, the Leviathan didn't have long to live, so for protection, it managed to find a Metroid who happened to be on the planet through unknown means. The Metroid would feast on its core, causing it to slowly mutate into Metroid Prime. The Chozo who lived on Tallon IV prophesied that it would destroy the planet, and thus they built the Artifact Temple around the Impact Crater to imprison it, though they knew the temple wouldn't be able to contain it forever.

Some years later, the Space Pirates discover the planet and its Phazon, and begin to collect it to see how they could weaponize it. Samus herself would eventually arrive on the planet when she answered a distress signal and found out it was the Space Pirates who sent it. During her journey to see what the Space Pirates where up to, she manages to learn about Metroid Prime through various Space Pirate Logs she can scan. At the end of the game, she manages to gain entrance to the Artifact Temple and explores deep into its depths, where she discovers the mutated Metroid in its Exoskeleton form!

Metroid Prime utilizes its various abilities to try and defeat Samus, as well as constantly switch between four colors - yellow, purple, white, and red - which signify which of Samus's beam weapons will be effective against it. Samus manages to overpower it, shattering its exoskeleton and exposing its core! At this point, Metroid Prime begins to summon various Metroids to attack Samus, as well as dropping pools of Phazon and turning invisible. Samus, thanks to her thermal and visor modes, as well as her Phazon Suit, would use the pools of Phazon and begin to blast away at Metroid Prime, defeating it!

However, in a last desperate attempt, Metroid Prime would lash out on Samus and steal her Phazon Suit upgrade before completely collapsing in a pool of Phazon. Afterwards, if the player has managed to obtain 100%, a hand from the pool of Phazon emerges, suggesting that Metroid Prime lives on...

And as Metroid Prime 2: Echoes would reveal, it did! Having absorbed the Phazon Suit, Metroid Prime has been reborn as Dark Samus! She has gained all of Samus’s abilities, and even some human-level cognition, though Dark Samus is completely obsessed with absorbing Phazon. She sets off on her quest and lands on the planet Aether, where the Space Pirates are mining Phazon in secret. Due to her similar appearance to Samus, the Space Pirates initially mistaken her for the Bounty Hunter and assume she's trying to steal the Phazon for her own agenda. During Dark Samus's raid for Phazon, she manages to break some Metroids out of containment.

Samus eventually arrives at Aether to investigate a missing team of Galactic Federation Marines who had landed on the planet to pursue the Space Pirates. Dark Samus would first meet Samus at the Marine base, where she was feasting on some Phazon. Once she realized Samus had arrived, she blasted the crystal near the Bounty Hunter before fleeing, leaving the mysterious yet malicious Ing to deal with her. This made Samus wonder if the two groups were working together.

Dark Samus would then see Samus again at Agon Wastes, located within the Space Pirates base. Dark Samus was absorbing some more of the Phazon the Space Pirates obtained there, and upon seeing Samus again, decided to battle her. Their fight would end with Dark Samus destabilizing and unleashing a massive explosion before collapsing, after which she disintegrated into various Phazon particles in the air.

At Torvus Bog, those particles would fuse together again. Turning her attention to Samus, she laughed maniacally before leaving. Near the entrance to Sanctuary Fortress, Dark Samus would show up again and destroy the bridge to the area, forcing Samus to find another way to get there.

Inside of the Sanctuary Fortress, Samus witnessed Dark Samus fighting some of the Dark Pirate Troopers, who were possessed by the Ing. This made Samus realize the that the Ing viewed Dark Samus as an enemy as well. Finishing the Dark Pirate Troopers off, Dark Samus absorbed several canisters of Phazon that they were guarding and left. Samus would then chase her down and confront her at a giant elevator called Aerie, where they have their second battle. Dark Samus is once again defeated and starts to lose her stability, and thus she decides to deliberately throw herself off of the building as a hasty retreat.

Much later in the game at the Sky Temple, Samus manages to defeat the Emperor Ing. However, his death means that Dark Aether is going to blow up in about 8 minutes, so Samus has to hurry and get back to Aether! However, just before Samus could get out, Dark Samus shows up and blocks the exit. Notably, due to all of the Phazon she absorbed, her suit had become transparent, revealing her various alien organs. Regardless, Dark Samus decided to use this opportunity to have a final duel with the Bounty Hunter. After a grueling battle, Dark Samus is once again defeated. Just like when she was Metroid Prime, Dark Samus tries to reach out to Samus in an attempt to steal her Light Suit upgrade, but disintegrates into Phazon particles before she can do so.

With peace restored to Aether, Samus left for parts unknown. However, if one managed to obtain 100%, a bonus scene would play after the credits showing that Dark Samus had managed to survive, if just barely.

In Metroid Prime 3: Corruption, the Space Pirates unknowingly scoop up some of her remains into their ship, the Colossus, when they were obtaining the Phazon that the Galactic Federation left behind on Aether. Absorbing the Phazon that the Space Pirates had collected to restore herself, Dark Samus had regained her physical armored look and full human-level cognition. She then proceeded to wipe out a third of the Space Pirate forces on the ship. After that, she used her Phazon to brainwash the rest of the Space Pirates aboard, forcing them to worship and follow her as "The Dark One", with promises of riches and power.

With the Space Pirates now following her orders, she manages to get to them to turn their ship into a Phazon-fueled craft, before heading off to locate the planet Phaaze: the source of all Phazon. Thanks to a Leviathan she happened to encounter, Dark Samus manages to bring her followers to the planet and announces her plans to conquer the galaxy by spreading Phazon everywhere. Though no one knows how to do that exactly, their answer comes around when they learn of the Galactic Federation's Aurora Units.

Raiding the G.F.S. Valhalla, killing its crew and ejecting the survivors out into the cold depths of space, Dark Samus and the Space Pirates manage to steal the ship's Aurora Unit 313, allowing Dark Samus to finally put her plans into motion. She corrupts the Aurora Unit with Phazon and then installs it in the center of the planet Phaaze, allowing her to control the planet and the Leviathans. She sends the first one to the Space Pirate Homeworld. Some of Space Pirates who weren't brainwashed try to fight back, but fail. She then presumably corrupts Aurora Units 242 and 217 during this.

Dark Samus would then send three more Leviathans to planets that were considered important to the Galactic Federation: Norion, which contained the important Base Sector Zero; Bryvo, the Federations primary source of Fuel Gel; and Elysia, which contained a vital research facility. While the Leviathans manage to successfully land on Bryvo and Elysia with no trouble, the one that was headed to Norion encounters opposition from Samus and three other bounty hunters: Rundas, Ghor, and Gandrayda. Just before any of the four can activate the cannon to stop the Leviathan, Dark Samus barges in through a window and repels their attacks with a Phazon Shield. She then overpowers them and proceeds to corrupt them with Phazon. Believing that she had stopped their attempts, Dark Samus leaves, unaware that Samus used the last of her strength to get to the cannon and fire it, destroying the Leviathan.

Regardless, Dark Samus chooses to mostly stay on planet Phaaze to continue her plans. Samus and the other bounty hunters manage to survive and head off to stop Dark Samus's plans. However, thanks to Dark Samus marking them with Phazon, all but Samus end up getting fully corrupted and possessed by Dark Samus. One by one, Samus is forced to kill them, after which Dark Samus arrives to absorb them to obtain their powers before leaving.

At the end of the game, Samus would head off to confront Dark Samus at her home planet, Phaaze, where they would have their final showdown. Dark Samus ends up taking considerable damage, and thus, as a last resort, merges with the Aurora Unit 313 to try and defeat Samus. After a grueling battle, the Aurora Unit was destroyed, and since it was directly linked to Phaaze's core, its defeat results in a chain reaction that causes the planet to blow up! Dark Samus is then ejected from the Aurora Unit as she dissipates into Phazon Dust, all while screaming out in agonized pain as she, her planet, and the Phazon get wiped from existence.

Personality-wise, Dark Samus is characterized as being utterly merciless and cruel, showing no regard to anyone who gets in her way. Despite that, she seems to hold some compassion to Metroids, most likely due to her previously being the heavily mutated Metroid Prime.

Back when she was Metroid Prime, she behaved on mostly animalistic instinct. Once she turned into Dark Samus, her personality shifted. In Metroid Prime 2: Echoes, she was mostly consumed with her single-minded goal to absorb Phazon, and would kill anyone who refused to give her it. Additionally, her mental state was pretty unstable, as she tended to laugh like a maniac and her battle tactics were unpredictable. By Metroid Prime 3: Corruption, Dark Samus's mental state has become more stable, making her calm and allowing her to calculate her plans more thoroughly.

In Super Smash Bros., Dark Samus is an Echo Fighter of Samus, sharing all of her moves. However, she does have a few differences to Samus, such as hovering above the ground when idling, walking, and running. If you’re good at playing as Samus, you should have no problems with Dark Samus!

Special Moves 

Neutral Special: Charge Shot

Dark Samus begins charging up a giant ball of energy. Pressing the Special Button again will have her fire it. The longer you charge, the faster it is and the more damage and knockback it delivers!

Inspired by Samus's Charge Shot upgrade that debuted in “Super Metroid.” Along with doing more damage, performing a somersault jump with the charge would allow Samus to deliver damage to a foe on contact, though this isn't portrayed in Super Smash Bros.

Side Special: Missile

Dark

Samus fires a missile. It’ll slowly fly towards the nearest target. Its not very strong, but its good for keeping foes away. You could also use it as you approach them.

 

If you input the move like a smash attack, Dark Samus fires a Super Missile! Its stronger and faster then a regular missile, but it doesn’t home in on the target. It also takes it a second before it reaches max speed.

Inspired by Dark Samus’s boss fight in “Metroid Prime 2: Echoes”. In that game, Dark Samus could fire either missle at Samus.

Up Special: Screw Attack

Dark Samus somersaults up into the air while electrical energy surrounds her. Anyone nearby gets dragged up with her before getting flung away.

Inspired by Samus's Screw Attack upgrade that debuted in “Metroid.” Whenever Samus performed a somersault jump - which is performed by jumping while Samus is moving - she'd form an electric barrier around her that would damage nearly any enemy she comes into contact with.

Down Special: Bomb

Dark Samus curls up into Morph Ball mode and drops a bomb. The bomb will detonate 2 seconds later, or if it comes into contact with an opponent.

If Dark Samus happens to be near the explosion of her bomb, she’ll curl back up into Morph Ball mode and get slightly flung into the air.

Every time Dark Samus drops a bomb, she’ll do a very small hop, even if she's in the air. One can use this to spend some extra time in the air..

In "Metroid Prime 2: Echoes", Dark Samus would use Morph Ball mode to use Boost Ball, a move that would send her speeding around the arena where she and Samus are fighting. However Dark Samus never uses bombs during any of her fights.

The bombs are inspired by Samus's Bomb upgrade in "Metroid". Samus could only use bombs in Morph Ball mode. The bombs aren’t the strongest weapons she has, and are usually reserved for blasting open walls or as a “last resort” type of weapon. The bombs explosions can also fling her slightly upward in the air, and using it can allow one to “Bomb Jump,” though its a very difficult technique to utilize throughout the series.

Final Smash: Phazon Laser

Dark

Samus readies her arm cannon in front of her, and fires a huge stream of Phazon in front of her! She can slightly angle the Phazone beam upwards or downwards. Anyone caught will get pushed away from Dark Samus, and will have difficulty escaping the beam. At the end of the move, she fires an even stronger blast that flings her trapped opponents away from her!

Inspired by Dark Samus's final boss fight in “Metroid Prime 2: Echoes”. In that game, she uses it not only as a powerful attack, but to also discharges excess amounts of Phazon energy to maintain stability.

Additional Notes 

If Dark Samus uses her grab move in the air, she’ll fire out her Grapple Beam, which does minor damage to an opponent. It can be used to mix things up, or as an attempt to hit someone from afar.

 

Dark

Samus can also use the Grapple Beam to grab the edge of a stage from afar, making it an alternative way of getting back up into the fight.

Before joining the battle in “Super Smash Bros. Ultimate”, Dark Samus was previously both an Assist Trophy and an alternate costume for Samus Aran in “Super Smash Bros. for Nintendo 3DS & Wii U.”

A similar Samus doppelgänger called SA-X - short for Samus Aran-X  - appears in Metroid Fusion. Unlike Dark Samus, who was initially a mutated Metroid, SA-X were created from an X-Parasite who attached itself to Samus's Power Suit and infected it. After the infected parts of the suit were removed and shipped off to the

Biologic Space Laboratories Research Station, they soon evolved into SA-X, with all of Samus's abilities, but without the knowledge on how to best use them... yet. Amusingly, Metroids are the natural prey of X-Parasites, so no doubt Dark Samus and SA-X would not get along.
