Extremely toxic mutagen

Phazon, referred to as the Great Poison by the Chozo, is an extremely radioactive and dangerous organic substance that can take on many forms. The mutagen is highly poisonous and corrosive, and contact with Phazon will result in immediate death or mutation in seconds.[1] Phazon spreads throughout the galaxy and manipulates organisms with Phazon Corruption. The toxic substance can destroy environments and entire planets. Phazon was first detected on planet Tallon IV, although it has been spreading across the galaxy long before the Corruption of Tallon IV from its planet of origin, Phaaze.[1] The plot of the Metroid Prime series revolves around Phazon and its destructive influence.

Phazon in Dark Aether

Not much is known regarding the true nature of Phazon as a material substance. It is highly radioactive, corrosive, and biologically toxic. Phazon has even demonstrated low-level sentience, as evidenced by creatures such as Phazon Grubs and Liquid Phazon, which are entirely Phazon-based.

Phazon has been used extensively by the Space Pirates for its effective mutagenic properties, which they have used to mutate their own genetic structure to produce more powerful and monstrous versions of themselves, as well as the genetic structure of other species. These beneficial mutations are limited by a notable decrease in the target bioform's life span, as it deteriorates cellular structure in addition to changing the genetic code. During the course of Samus's visit to Phaaze, the Phazon inside of her even affected her genetic structure to the point where her ship's bio-scanners could not recognize her.

Metroid Prime[edit | edit source]

Some 50 years prior to the events of Metroid Prime, a meteor infected with Phazon struck the planet Tallon IV, causing great devastation and forcing the Chozo colonists who survived to flee.[2] Before abandoning the planet, the Chozo attempted to contain the spread of Phazon on the planet at the impact site by means of a Cradle and Cipher.

At the heart of the impact site was a Metroid specimen whose exposure to raw Phazon radically mutated it. It became the subject known as Metroid Prime. After its defeat by Samus Aran, Metroid Prime ensnares her Phazon Suit and uses it and parts of Samus's own DNA to eventually become the organism known as Dark Samus.

Space Pirate crates leaking Phazon

Around this same time, Space Pirates discovered Phazon and began mining operations of high-yield sites and experimention with its biomutagenic properties. Samus first encounters Space Pirates using Phazon in this way on the Frigate Orpheon, where mutations of native Parasites resulted in Parasite Queens. Initial experiments were made on Tallon Metroids in the Glacier One outpost in Phendrana Drifts, which the Space Pirates planned to use as weapons and power sources. Tests yielded such results as Hunter Metroids and Fission Metroids. Later experiments, such as Project Titan, which focused on the mutation and animation of inanimate objects,[3] resulted in the specimen Thardus before it was completely shut down.[4] Project Helix, which aimed to mutate Space Pirate DNA with Phazon,[5] finally succeeded when the Phazon Strain Vertigo was discovered by Research Team Sclera and several specimens, including Elite Pirates, a Phazon Elite, and the Omega Pirate, survived to maturity.[6]

Metroid Prime 2: Echoes[edit | edit source]

Dark Samus absorbing Phazon energy

Phazon was first introduced to the planet Aether at the beginning of the Luminoth Dark Age. A Leviathan impacted the planet, sending it into a state of Transdimensional Flux that ultimately resulted in the creation of Dark Aether and the Ing.[7][8] Space Pirate Science Teams detected the presence of Phazon in the Dasha System seven cycles prior to Samus's arrival and established a base on the planet.[9] Expeditions through a dimensional rift revealed that Dark Aether contained vastly superior deposits of Phazon than its light counterpart and extraction missions were soon conducted regularly.[10][11] Metroid Prime, reborn as Dark Samus and mistaken for Samus Aran by the Space Pirates, soon began raiding their base and stealing Phazon for her own purposes.[12] Dark Samus eventually absorbs so much Phazon energy that she becomes a being of pure yet unstable Phazon.[13]

Following the destruction of Dark Aether and the Ing, a Galactic Federation vessel, the G.F.S. Anhur, returned to Aether to assist the Luminoth in dismantling the Space Pirate mining facility. Several kilograms of Phazon ore recovered during this time later led to the development of the Phazon Enhancement Device.[8]

Dark Samus, reformed in the Phazon storage of the Space Pirate vessel Colossus, took control of the Space Pirate crew and then ventured alone to Phaaze.[14][15] From there, she sent a Leviathan seed to the Pirate Homeworld, which was gradually corrupted.[16] Afterwards, she sent Leviathans hurtling towards the Federation planets Bryyo, Elysia, and Norion.[17]

This crate appears to be the same type of container found on the Space Pirate research frigate. The material seeping out from the ruptured metal is highly toxic. Analysis indicates this may be the 'Phazon' compound the Space Pirates were using in their biological experiments.[21]

Logbook Entries[edit | edit source]

Logbook entry from Metroid Prime 2: Echoes: Phazon
Volatile ore with biomutagenic properties. Origin point of Phazon unknown. First detection of element on planet Tallon IV. Used by Space Pirates to produce vast levels of energy. Bioforms exposed to Phazon without proper shielding will eventually undergo radical mutation.[1]

  2. "Planet Tallon IV, formerly a Chozo colony, was struck by a stellar object 50 years ago. Object was later determined to contain large quantities of Phazon. The Chozo were able to stave off the spread of Phazon, at the cost of many Chozo lives. The survivors abandoned the planet, fleeing to an unknown location." —Galactic Federation Data "Tallon IV Incident" (Metroid Prime 3: Corruption)
  3. "Research on Tallon IV is expanding into new areas. Pending stabilization of the Thardus venture, we will expand Inanimation research to include other native Tallon IV materials." —Scan Data (Metroid Prime)
  4. "Project Titan is suspended indefinitely. Security breaches resulting in massive casualties have occurred. Access is strictly prohibited until further notice." —Scan Data (Metroid Prime)
  5. "Confidence is high regarding Phazon applications. We know enough about Phazon now to begin combining it with Space Pirate DNA. The code name for this venture will be 'Project Helix'. Preliminary studies indicate that Phazon infusion could produce radical new Pirate genomes. Benevolent mutation levels are high in current test subjects. Phazon madness is a concern, but refinements in the infusion process should reduce or neutralize the odds of mental degeneration." —Pirate Data "Phazon Infusion" (Metroid Prime)
  6. "Initial Project Helix experiments with Space Pirate embryos were disastrous. The Phazon-infusion process degenerated brain tissue even as it augmented muscle mass. None of what we have termed 'Elite Pirates' lived to maturity; the few that survived their infanthood suffered severe psychotic breakdowns as juveniles, killing anything within their zone of perception. Research team Sclera made a recent breakthrough, in which parasite studies with a Phazon strain code-named 'Vertigo' were highly successful. Since then, we have fused Vertigo Phazon with Space Pirate DNA with great success. The latest batch of Elite Pirates have reached maturity successfully and are ready for field testing and training." —Pirate Data "Elite Pirates" (Metroid Prime)
  7. "The starborne terror burnt through the heavens and struck Aether with and untold might. We all expected the world to shatter...but Aether held. There was great devastation, however. The green plains of Agon were scorched forever, and the forest of Torvus was engulfed and wracked by the sea. The skies burned for days, casting darkness over the land." —Metroid Prime 2: Echoes Logbook "Cataclysm" (Metroid Prime 2: Echoes)
  8. 8.0 8.1 "Planet Aether, home of the Luminoth, was struck by a “Phazon Meteor” five decades ago. The impact had catastrophic effects on the already unstable planet, creating a “dark twin” of the planet and a fierce race known as the Ing. A brutal war between the twin planets took place, with the Ing gaining the upper hand. The G.F.S. Tyr went to the sector to investigate pirate activity, but were forced to make an emergency landing on Aether. Shortly after, the entire crew of Tyr was attacked and annihilated by the Ing. Hunter Samus Aran was sent to investigate, and wound up entangled in the local conflict. Aran fought against both Space Pirates and Ing, and arose victorious. Aether’s “dark twin” vanished, taking with it the Ing horde, and the planet’s peace was finally restored.
    After the Aether incident, the Federation sent the G.F.S. Anhur back to Aether to deal with the pirate base. Upon arrival, the crew and marines of the Anhur assisted the native Luminoth in dismantling an abandoned Space Pirate mining facility. During the operation, the crew detected the presence of Phazon. The ship’s crew investigated and collected several kilograms of ore, which would later lead to the development of the PED.

  9. "Science teams have discovered the presence of Phazon in the Dasha system four cycles ago. High command authorized the deployment of our team shortly thereafter. Our orders are to establish a base on planet Aether and evaluate local Phazon resources. Because this world lies on the periphery of Galactic Federation territory, we are following stealth protocols at the highest level. A cadre of elite commandos has been dispatched to provide security for our force as well. This operation is now under way." —Metroid Prime 2: Echoes Logbook "Log 04.468.1 (Phazon Operations)" (Metroid Prime 2: Echoes)
  10. "The Rift Portal has been opened. The artifact weapon, dubbed the "Dark Beam" by science team, provides energy needed to open the portal, although for a limited time. We've sent expeditions through the portal, and they have returned with incredible news. The portal leads to a parallel version of Aether. This "Dark Aether" has suffered a global calamity, turning it into a toxic wasteland. It is the homeworld of the shadowy creature who have been raiding our base for the last cycle. Most importantly, it is the prime location of Phazon in this sector. Extraction plans are being prepared. We will not be denied!" —Metroid Prime 2: Echoes Logbook "Log 05.422.1 (Rift Portal)" (Metroid Prime 2: Echoes)
  11. "Phazon extraction raids are under way on Dark Aether. The toxicity of the atmosphere has taken a toll on our workforce, as have the hostile natives of that world. Science Team is preparing survival gear to protect our work teams, and we have increased our security presence in extraction areas. Fortunately, High Command is sending more troops and supplies. Our troops and resources are spread dangerously thin, and this mission cannot fail." —Metroid Prime 2: Echoes Logbook "Log 06.221.7 (Phazon Raids)" (Metroid Prime 2: Echoes)
  12. "Samus Aran, the accursed Hunter, has arrived. The sudden arrival of the Hunter is strange enough, but her actions are stranger still. She does not seek our destruction, but our Phazon. With each raid, she steals Phazon ore, only killing those who attempt to deny her. What she needs it for we do not know - though Science Team suspects she requires it to power her new armorsuit. Dark in color, it is equipped with strange new weapons. The troops now call her the "Dark Hunter." It is a fitting title." —Metroid Prime 2: Echoes Logbook "Log 06.362.2 (The Hunter)" (Metroid Prime 2: Echoes)
  13. "Dark Samus has temporarily become a being of pure yet unstable Phazon energy. She can generate a shield that is invulnerable to all attacks, save one - blasts of Phazon energy itself. Use your Charge Beam to collect Phazon energy that she expels, then fire it back at her. Direct hits will overload and disrupt her essence." —Metroid Prime 2: Echoes Logbook "Dark Samus 4" (Metroid Prime 2: Echoes)
  14. "Our attempts to intercept the Federation ship departing Aether were unsuccessful. With them went a collection of Phazon, the first to fall into Federation hands. They foolishly left most of the Phazon behind, allowing us to quickly collect what we could. But in our haste we took more than mere Phazon. Our scanners have detected the remains of Dark Samus, who has revived herself within our Phazon storage. Surely, we are cursed. The fiendish shrew consumed all of the Phazon, then wiped out a third of the crew in a matter of minutes. Now she moves at will through the halls of Colossus, using her witchery to beguile the minds of the crew. We are unable to call for aid, and only a few of us remain to stand against her. All is lost." —Metroid Prime 3: Corruption Logbook "Stowaway" (Metroid Prime 3: Corruption)
  15. "After our liberation, she left us adrift. We thought this a test of our loyalty, and so we endured. Some said she abandoned us. They were promptly shot. Disciples do not doubt their leader. When she returned, it was on the back of a titanic starborne beast! As we groveled in awe, she ordered us to follow the beast through a rift in space, a wormhole. Some refused to follow, afraid of the unknown. They too were shot. Disciples must be fearless. Once through the rift, we saw a singular wonder...Phaaze, the source of all Phazon in the cosmos. Phaaze, the home of our glorious leader!" —Metroid Prime 3: Corruption Logbook "The Source Discovered" (Metroid Prime 3: Corruption)
  16. "Our great leader, with the aid of our captured Aurora Unit, has discovered many of Phaaze's secrets. Dark Samus can now command the living world to send forth Phazon Seeds! She was eager to test this new power. When we heard the first world to receive this blessing was our Homeworld, we rejoiced. The Seed was sent into the void, and quickly made its way to our Homeworld. Our brethren foolishly tried to repel it, but their efforts were in vain. To think, once we were as pathetic as them! Now the deed is done, and slowly, our Homeworld becomes like Phaaze. Soon, there will be two living planets, two Phazon sources for our great leader to use as she sees fit. Soon, there will be thousands of new disciples for her to command." —Metroid Prime 3: Corruption Logbook "Purification" (Metroid Prime 3: Corruption)
  17. "The time has come, our leader commands. We go to war at last! Three worlds will be attacked, each important to the Federation. We shall destroy the spy base at Elysia, the fuel production of Bryyo, and the naval station at Norion. Each of those wretched worlds will become as Phaaze...each a foothold into the territory of the hated Federation. From those worlds, our vanguard will go forth. At long last, our enemies will be humbled, then enslaved. Three Phazon Seeds will be sent, and an armada will accompany each of them. Dark Samus herself will lead the attack on Norion. Victory is ours for the taking!" —Metroid Prime 3: Corruption Logbook "Vanguard" (Metroid Prime 3: Corruption)
