Harmony Class Drone
Harmony Class Drones are Luminoth built mechanoids found in the Great Temple and Sanctuary Fortress on Aether. They are similar to the Pulse Bombus on Tallon IV. They were originally designed to be used as cleaning units, but became aggressive and now attack all living creatures. They attack by firing focused beams of electricity and pulses. Unlike a Diligence Class Drone, Harmony units are vulnerable to a variety of weaponry.
- "The Luminoth designed the Harmony units to be free-roaming, independent units. They use focused electrical beams and kinetic pulses to perform their duties. Unfortunately, they now consider all living things as filth that must be cleansed from the world." — Logbook "Harmony Class Drones" (Metroid Prime 2: Echoes)
