PFC O. Grippe

Private First Class O. Grippe was a tech part of GFMC Task Force Herakles who, like the rest of the troopers, was killed when the Splinters attacked. He was most likely turned into a Dark Trooper.

Grippe has an unused Logbook entry that names him as T. Ivey, and reveals that he detected a Gunship flying onto Aether. It was determined not to be with the Galactic Federation or Space Pirates, so it is possible that he detected Samus's Gunship.
