The Luminoth M-Dhe was one of the ten Keybearers sent to collect the Sky Temple Keys and is called "fearless" by A-Kul. Though successful in finding a key, M-Dhe's armor was breached and the Keybearer succumbed to Dark Aether's poisonous atmosphere. M-Dhe fell in the Landing Site of the Temple Grounds. Samus later recovers the key in the Defiled Shrine of the Sky Temple Grounds.
- "Fearless M-Dhe. The one who shall move the pillar of holy ground will see your soulless body." —Metroid Prime 2: Echoes Logbook "M-Dhe's Key" (Metroid Prime 2: Echoes)
- "The last hit breached my armor. The poison spreads. Though I have found the key, it is too late for me. Soon my light will fail. They know I am here. They will come to this site to plunder the key. My last stand shall be at the edge of the temple grounds. I only hope I have the strength to fight when they arrive." —Metroid Prime 2: Echoes Logbook "M-Dhe's Testament" (Metroid Prime 2: Echoes)
