The intergalactic bounty hunter named Samus Aran. Orphaned at an early age, she was taken in and raised by the alien race known as the Chozo. The Power Suit she wears is a product of their technology. Her unique combat skills combined with her athleticism and Arm Cannon have seen her through countless missions.
Samus's Final Smash. The beam emerging from her Arm Cannon is dreadfully powerful and causes great damage to enemies. The beam travels slowly but can be swept up and down. The recoil of the beam is so great that it tears off her Power Suit, revealing Zero Suit Samus. The pieces of her armor can be picked up and thrown as weapons.
Zero Suit Samus
Samus Aran without her mighty Power Suit. In this condition, she does not have the firepower she's famed for but is in full possession of the agility and athleticism she gained through her childhood training with the Chozo. Without the armor, she's also much, much faster. The weapon she carries is a self-protection device known as a Paralyzer that stops enemies cold.
Power Suit Samus
Zero Suit Samus's Final Smash. Samus loses her Power Suit when she fires the Zero Laser, but she can restore it--that is, she can return from her Zero Suit form to her familiar armored form. That being said, Zero Suit Samus is very quick with great reach, so there are tactical reasons to fight as is. If that's your preference, don't pick up any Smash Balls.
Samus (Fusion Suit)
During exploration of SR388, Samus is infected by an X parasite and nearly dies. A vaccine created from Metroid cells saves her, but her suit turns blue and loses most of its abilities and weapons. This new Samus must regather her special abilities and fight to neutralize the threat of the X parasites in the space station run by Biologic Space Laboratories.
Samus (Power Suit)
Samus in the basic version of the legendary Power Suit, made for her by the Chozo race. Samus is most often seen at the beginning of each game in this suit. The normal Power Suit has the lowest level of protective power and features no additional functions. She can use the cannon on her right arm for power shots and build up her arsenal through item pickups.
Samus (Varia Suit)
A suit with a higher level of protection than the Power Suit. It eliminates damage caused by very hot or cold areas. It is also more resilient to enemy attacks than the Power Suit and greatly differs in shoulder design. Recent visual depictions of Samus often show her wearing the Varia Suit.
Samus (Gravity Suit)
A Power Suit that provides even more damage protection than the Varia Suit. This Gravity Suit also allows Samus to move without water resistance when underwater. In most games in the series, this suit also blocks lava damage and friction. In addition, it allows Samus to use item bonuses like the High Jump, Space Jump, and Speed Booster, even when underwater or in lava.
Samus (Dark Suit)
A Power Suit that reduces damage taken from the atmosphere of Dark Aether. It is obtained after defeating Amorbis in the Dark Torvus Temple. With its increased protection, it greatly widens the range of exploration available in the toxic atmosphere. This suit was developed by the Luminoth, the native race of Aether.
A bioengineered life-form found on planet SR388. Metroids attach to organisms and drain life energy. The Galactic Federation commissions Samus to eliminate them, but Space Pirates try to harness their power. One of the few ways Samus can kill Metroids is by shooting them with the Ice Beam and then shattering them with missiles. The Metroid's cry is chilling and indescribable.
The leader of the Space Pirates. He looks like a pterosaur but has high intelligence and a brutal nature. He plans to steal the baby Metroid from Samus for his own use. Ridley utilizes wings for a full range of flight and attacks with fireballs from his mouth and whips of his tail. As the culprit behind the murder of Samus's parents, the connections with Samus run deep.
The meta form of Ridley, revived using the Space Pirates' genetic engineering and cybernetic technologies. His thin chest plate--and weak point--is protected by a highly resistant membrane. Meta Ridley is highly mobile and features a multimissile system, a bomb launcher, and powerful wings. Ice attacks are particularly effective in dealing damage to him.
An enemy of Samus. They land on Tallon IV and use the energy they find there--called Phazon--for brutal experiments on the planet's life-forms. Samus makes for Tallon IV to destroy the experiment facilities. In Metroid Prime 2: Echoes, the pirates go to Aether to find Phazon. A war is being waged there, and a race of dark beasts, the Ing, make research difficult.
Space Pirates performed many experiments using Phazon as a means to artificially enhance physical strength. The Parasite Queens are the result of these experiments on one small life-form. This Parasite Queen lived in a nuclear power reactor and fired destructive beams at Samus from its mouth. The barrier that spun around the queen reflected its and Samus's attacks.
Metroid Prime (Exo)
The form of the Metroid Prime that Samus first encounters. It can become invulnerable to all but one of Samus's weapons at a time. The body color alternates between yellow, purple, white, and red, with the color indicating the weapon that can deal damage. After taking a certain amount of damage, the Metroid Prime exoskeleton reveals its core essence.
Metroid Prime (Core)
The core form of Metroid Prime after losing its exoskeleton. It can make itself invisible for a set time, which requires Samus to make a visor change. Normal hits do not have any effect on it--the Metroid Prime can eventually be defeated by using the Phazon Beam while standing in a Phazon puddle.
A twin image of Samus, encountered near the beginning of Metroid Prime 2: Echoes. Dark Samus is identical to Samus in every way but color-- she even uses similar attacks. There are many theories on the origin of Dark Samus, but none are proven. Dark Samus uses Phazon for energy and can absorb it to heal damage. Samus encounters Dark Samus a number of times.
A creature of the native race of the planet Aether. The Luminoth develop facilities to draw the dwindling energy from the core of their planet. However, they lose that energy when the planet is hit by a Phazon meteor and they are attacked by a race of dark creatures, the Ing. A war over Aether's energy then rages between the Luminoth and Ing races.
A bounty hunter seeking the ultimate power--the secrets of the Alimbics--on a savage planet in a far corner of space. Kanden is the result of a failed lab experiment meant to create invisible soldiers. He seeks the ultimate power to prove himself as the greatest hunter ever. Kanden's weapon is the electrically charged Volt Driver.
Another hunter seeking the ultimate power, and the last of the silicon- based Diamont race. By finding the secrets of the Alimbics, he hopes to uncover the secret of why his race went extinct. Spire uses the Magmaul, a weapon passed down through Diamont generations, to launch burning magma at opponents.
A cyborg Space Pirate and member of a special-forces unit. Weavel was once left for dead in a fight with Samus. Like other hunters, he also seeks the ultimate power. His weapon of choice is the rapid-fire, heavy-duty Battlehammer. Weavel can transform into the Halfturret, where his upper and lower body split and can attack separately.
A bounty hunter and member of the elite Vhozon race. He seeks the ultimate power if only to ensure that no one else possesses it. Noxus uses the Judicator, an ice- beam weapon which, in addition to its offensive ice blasts, features a protective field that freezes opponents.
A bounty hunter and member of the Kriken Empire, which is despised for ruthless invasions of planets. He seeks the ultimate power in order to further empower his people and gain fame and strength for himself. Trace has stealth capabilities and can make himself invisible. His weapon is the Imperialist, a sniping laser.
A skilled marksman and bounty hunter experienced in espionage skills such as scouting and tracking. While much of his background remains a mystery, it is clear that he hates Samus and the Federation. Sylux uses the Shock Coil, an experimental Federation-made weapon that continually drains energy from enemies and refills his own.
A boss guarding the Wave Beam in the icy Chapel of Elders. It appears after Samus defeats four Baby Sheegoths. The crystals on its back will absorb any shots, so the trick is to shoot it in the head with missiles when its mouth is wide open. The Plasma Beam deals severe damage to this creature.
A badge you can wear to turn your jumps into Samus's signature Screw Attacks. In Super Smash Bros. Melee, it was an item you carried, but this time around it's a badge you wear--which means you can use it and another item at the same time. There's a good chance you'll be able to string together Screw Attacks and midair strikes for powerful combos.
The ship that Samus pilots. Entering the gunship allows Samus to restore energy and save. Samus has been on numerous voyages in the gunship, but after being attacked by an X parasite in Metroid Fusion, she crashes into an asteroid belt and destroys the craft. After that, the Galactic Federation provides her with a new starship.
