Devon III is a planet briefly referred to in Metroid Prime 2: Echoes. Though it goes unnamed in the final game, its name is given in a Trooper Logs entry of SPC B. Campbell. SGT E. Monz is said in an unused Logbook entry to have been stationed on Devon III when he was a green private, where an infestation of insectoid creatures similar to Splinters occurred, and it took two cycles to exterminate them.
