Appearing in Metroid Prime 2: Echoes, J-Fme was a Luminoth Keybearer who had to collect one of ten Sky Temple Keys and deliver it to a gate in order to destroy the Ing. J-Fme died in the Industrial Site of the Temple Grounds, most likely in combat with Darklings or rogue Luminoth robots. Little about the warrior is known, except that A-Kul referred to J-Fme as being mighty.
