Phazon

Phazon is a highly raidoactive mineral. Its origin is unknown. First encounter with phazon was on Planet Tallon IV, chozo lore states that phazon came in a meteorite with the unholy worm (metroid prime), two kinds of phazon were encountered there, red and blue. Red phazon, 86% more radioactive than blue phazon, was only encountered on the impact crater, but never on prime´s chambers. After prime was defeated by Samus Aran, it absorved samus´ phazon suit, and evolved into Dark Samus. Second encounter.
