Biography of Dark Samus

Dark Samus was a being of Phazon created after the dying Metroid Prime absorbed Samus' Phazon Suit and her DNA. It had many battles with Samus during it's search for Phazon on the planet Aether and later returned as the mastermind of the Space Pirate invasion until it's defeat and demise on Phaaze. Below was a full account of it's history.

Death and Rebirth

The birth of Dark Samus

After Samus defeated Metroid Prime on Tallon IV by overloading it with the Phazon Beam, the creature began to destabilize and in a desperate move, it absorbed her Phazon Suit and subsequently exploded. Little did Samus know that as she left the planet, a new enemy was born from her DNA and the remains of Metroid Prime. The Phazon Suit was a necessary piece of this fusion as Metroid Prime destabilized and no longer had a body. With it's acquired human DNA as well as the Phazon Suit as a body to construct itself into, it formed itself into a new enemy which was the creature known as Dark Samus.

Search on Aether

Dark Samus, now with a new form based on Samus' Power Suit and instincts that commanded it to absorb and spread Phazon managed to leave Tallon IV in search of it in Samus' stolen Phazon Suit, though now black and dark blue in color with skeletal features and Phazon markings. Dark Samus eventually discovered the planet called Aether which was rich with Phazon. A Leviathan from Phaaze landed on the planet fifty years prior, ripping a second, darker dimension called Dark Aether open. Dark Samus explored Aether and absorbed any Phazon that it could find on the planet.

Pirate Raids

The Space Pirates, prior to Dark Samus' arrival established a base on Aether. Once Dark Samus arrived, they initially thought that she was Samus Aran, but are perplexed to it's strange dark suit and it's actions. It only raided their base to obtain Phazon, killing any who denied it. Some of their Metroid specimens are also reported stolen and the Pirates, having spotted it at one time near the containment tanks attempting to breach them believed that this "Dark Hunter" was to blame for the theft. Dark Samus also destroyed their stealth generator in one of it's raids, causing disastrous results for the Pirates.

Encounters with Samus

Samus Aran eventually landed on Aether to investigate a missing team of Galactic Federation Marines who landed on the planet in pursuit of a Space Pirate starship. Samus first encountered Dark Samus in the marine base where Samus followed it into a portal to Dark Aether. There, she found Dark Samus absorbing Phazon with several shadowy creatures above which Samus would soon learn are the Ing. Dark Samus fired a shot at the Light Crystal that protected her from Dark Aether's poisonous atmosphere. With the crystal broken, the Ing stole most of Samus' abilities while Dark Samus fled. Samus escaped through the portal with only a few pieces of equipment intact. It was at first unclear if this meant that Dark Samus was working directly for/with the Ing Horde though it was only due to the Ing choosing to attack Samus over the far less vulnerable Dark Samus as she could not resist Dark Aether's atmosphere. A Pirate scout witnessed this encounter and believed that they are not allies, but foes. The Pirates considered employing Dark Samus to kill the real Samus with precious Phazon as a reward, though unfortunately they did not have time to put this plan into action.

Dark Samus engages Samus in the Agon Wastes.

The next encounter took place in the Agon Wastes within the Pirate base. Dark Samus appeared in front of Samus behind a locked gate and left. Unable to bypass the gate, Samus explored the rest of the base and reached a room full of Phazon collected by the Pirates. There, Samus had her first battle with Dark Samus. Once Dark Samus was defeated, it began to destabilize and unleashed a massive Phazon explosion before collapsing and disintegrating into Phazon particles in the air.

The particles that Dark Samus transformed into managed to reach Torvus Bog. Samus saw the cloud transform into Dark Samus, though it did not fight Samus. Instead, it merely laughed maniacally and disappeared. Samus later saw the same cloud in the Sanctuary Fortress and it once again transformed into Dark Samus. She destroyed the bridge to the Sanctuary Fortress and left, forcing Samus to find an alternative route across the chasm.

Samus later saw Dark Samus in the Fortress firing at several Dark Pirate Troopers. This confirmed that the Ing regarded her as an enemy and not an ally as they thought at the beginning. She disposed of them and began absorbing several canisters of Phazon (Showing just what happened if Dark Samus was denied Phazon). Samus pursued her foe, cornering Dark Samus within an elevator and battling it once more. Samus defeated it once again and the doppelganger, losing stability in it's body allowed itself to fall off the top of the tower as a hasty retreat before Samus attempted to stop it.

Dark Samus and Samus face off as Dark Aether collapses around them.

Final Battle

Once Samus defeated the Emperor Ing and absorbed the remaining planetary energy, Dark Aether became unstable and began to collapse. Samus, having only eight minutes to escape hurried out of the Sky Temple and began moving toward the exit. However, her hopes of escape are crushed when Dark Samus appeared, blocking the exit with a Phazon wall. Due to the huge amount of Phazon that it absorbed, Dark Samus began to deteriorate, causing it's suit to become transparent and revealing it's organs along with a humanoid skull with three yellow eyes inside it's helmet. The eye on the back of her hand featured on the arm that reached out of the pool at the end of the first game was also rendered visible (Though with a smaller pupil and yellow rather than blue).

Both Samus and Dark Samus engaged in a grueling battle, though Samus managed to defeat it once again by taking advantage of her foe's sole weakness: An overload of Phazon. Samus absorbed Dark Samus' Phazon into her Charge Beam and shot it back. The attack penetrated Dark Samus' Phazon shield and caused Dark Samus to destabilize, just as it had as the Metroid Prime and it collapsed, defeated once again by it's own attacks. In it's dying moments, it painstakingly reached out in an attempt to touch Samus (Possibly trying to absorb the Light Suit like she did to the Phazon Suit), but de-materialized into a cloud of Phazon particles at the last second. Samus escaped from Dark Aether and brought peace to the Luminoth on the planet and it seemed that Dark Samus perished along with Dark Aether.

Yet, even though Dark Samus lacked a corporeal form, it still existed and as shown in the 100% ending of Echoes which the Phazon particles again reformed into Dark Samus's body, it would be only a small amount of time before it would return.

Return

Dark Samus at the beginning of Corruption.

Sometime between the events of Metroid Prime 2: Echoes and Metroid Prime 3: Corruption, the Galactic Federation, seeing great use for the mutagenic substance took some of the Phazon from Aether. However, they left most of it behind and the Space Pirate crew of the battleship called the Colossus soon collected the remaining Phazon. However, they would soon find out to their horror that they unknowingly took the particles of Dark Samus as well. Using the Phazon collected by the Space Pirates, Dark Samus regained it's physical form (Now with a more armored look as opposed to it's previously organic appearance) and wiped a third of the Space Pirates out aboard the ship. It used it's Phazon energy to brainwash the rest into accepting it as their new leader with the promises of incredible riches and power.

The Seeds of Scheming

With the Pirates so suckered into it's schemes, a quasi-religious cult began to form around it and they followed it's every whim. It taught the crew to turn the Colossus into a mighty Phazon-fueled craft. It left them for several months to locate the source of all Phazon which was the planet called Phaaze. During it's absence, it's followers maintained order by executing those who doubted that it would return. During it's journey, it encountered a Leviathan and used it's energy to take control of it which led it to Phaaze. For Dark Samus, the chance to control the source of all Phazon was a chance to control the universe. Dark Samus absorbed a tremendous amount of Phazon, increasing it's power to new heights. It returned to the Pirates with the Leviathan and commanded them to follow it through the wormhole to Phaaze. She revealed it's plan to take control of the planet and to speed the Leviathan production up, spreading Phazon strategically across the universe. How to do this was a dilemma, but a solution soon presented itself in the form of the Federation's Aurora Units.

Raid on the Valhalla

Under it's orders, the Space Pirates attacked the G.F.S. Valhalla and stole the ship's Aurora Unit, 313. If the survivors of the raid expected mercy, they did not receive any. Under Dark Samus' orders, the Pirates jettisoned the survivors into the cold depths of space. The Aurora Unit was corrupted with Phazon and implanted into Phaaze, allowing Dark Samus to directly control the planet and all of it's assets including the Leviathans. The first Leviathan that it controlled was sent to the Space Pirate Homeworld. According to the Space Pirate Data, the Space Pirates on the homeworld that are not brought under Dark Samus' control fought back against the Leviathan, but failed. All of the remaining Pirates are brainwashed. Dark Samus presumably also used 313 to infect the other Aurora Units (In particular, Aurora Unit 242 of the GFS Olympus and Aurora Unit 217 of Skytown respectively.) with the Corruption virus.

The Invasion of Norion

Next, Dark Samus sent three more Leviathans to the planets that are important to the Galactic Federation. One to Norion, containing the important Base Sector Zero; one to Bryyo, the Federation's primary source of Fuel Gel and the last to Elysia, containing SkyTown, a vital research facility. Presumably, it also proceeded to cause an anomaly to Samus' cryostasis while she was on her way to Norion. While the Bryyo and Elysia Seeds collided without any trouble, Dark Samus encountered opposition on Norion - specifically, in the form of Samus Aran and the three other Bounty Hunters: Rundas, Ghor and Gandrayda. Just before they activated the cannon to destroy the oncoming Leviathan, Dark Samus confronted them, crashing through a window and repelling the Hunters' attacks with a Phazon shield. Despite the Hunters' efforts, she overpowered them and corrupted them with Phazon. Believing it's work to be done, Dark Samus flew off, but Samus, using the last of her strength managed to activate the cannon and destroy the Leviathan before falling unconscious.

After this, Dark Samus herself stayed on Phaaze and did not appear to the bounty hunters, busy performing their duties of destroying the Leviathans. However, due to it's "mark of corruption" that it left on all four of the bounty hunters, all, but Samus succumbed to the Phazon Corruption and became completely possessed by Dark Samus (This was most evident in the cutscene just prior to the battle with Rundas). Over the course of the game, Samus was forced to kill all three of them. Each time that one of them died, a shadowy apparition of Dark Samus appeared before them, absorbing their bodies and their powers. This form was a black collection of smoke that had what may be tentacles acting as "wings". After each absorption, Dark Samus swooped down and flew away. This form depicted Dark Samus' visor.

The Final Confrontation

Dark Samus was confronted for the final time in it's Sanctum on Phaaze where it challenged Samus to a grand final battle. However, after being injured considerably, Dark Samus called the stolen Aurora Unit 313 forth and merged with it in a last-ditch effort to defeat Samus. After a grueling two-part battle, the Aurora Unit was destroyed and because it was directly linked to Phaaze's core, it began a chain reaction that culminated in Phaaze exploding. As a result, Dark Samus was ejected from the Aurora Unit and exploding into Phazon dust with agonized cries was destroyed for good.
