In Metroid Prime 2: Echoes, the Keybearers were ten Luminoth warriors organized to find and use the ten Ing Sky Temple Keys to infiltrate the Sky Temple. They were divided into two Cadres of five warriors each. Each warrior managed to find a key; however, all were subsequently hunted down and killed by the Ing before they could return it to the Temple. The sole exception was A-Kul, who left only nine Keys for Samus Aran to find. Parallels can be drawn between the Luminoth Cadres and two Forces of GFMC Task Force Herakles.
