In Metroid Prime 2: Echoes, the Green Kralee is a species of Kralee that, due to a genetic defect, lacks the ability to phase. The Green Kralee is not an aggressive species and will only attack if something is directly in its path. Green Kralees are a minimal threat, dealing very low amounts of damage.
- "The cousin to the dimensional-shifting Kralee, the Green Kralee spends its days roaming in search of food. A genetic defect prevents its back crystal from harnessing energy and opening warp portals. It is doubtful the Green Kralee misses this ability." — Logbook "Green Kralee" (Metroid Prime 2: Echoes)
