M-Dhe was one of the 10 Luminoth Keybearers featured in Metroid Prime 2: Echoes. This individual was one of the few to successfully collect a Sky Temple Key but failed to take it to the Sky Temple. The Luminoth warrior died in the Landing Site room in the Temple Grounds of Aether, either of exhaustion, wounds received in battle, or fighting with the Ing. A-Kul refers to the Luminoth as fearless in one of her clues, but no other details are mentioned in the game, including M-Dhe's sex.
