The Phazon Enhancement Device Suit is a Phazon Enhancement Device designed for Samus Aran. After Dark Samus corrupted her, Ghor, Rundas, and Gandrayda, their bodies began producing Phazon. The Galactic Federation rebuilt Samus' suit with their PED technology so that she may safely harness Phazon. Phazon Units replace the usual Energy Units, and exposure to some forms of Phazon will restore Samus' energy. The PED is similar to the Fusion Suit in that it melds Samus' Power Suit with GF technology. The PED is also described as a 'fusion' between GF and Chozo technology in its description.
