In Metroid Prime 2: Echoes, the Harmony-Class Drone is a light cleaning and service drone that functions using focused energy beams and small pulses of electricity that are "dropped" by the mechanoid onto surfaces beneath it. It was designed by the Luminoth to clean organic matter from their corridors and homes. However, a programming fault causes all of them to treat any living matter as filth, which leads them to attack organisms that enter their designated cleaning area. However, their cleaning apparati are only a small threat to sentients.

Harmony-Class Drones are only found in two rooms: Transport C Access and Minigyro Chamber.

Logbook entry

The Luminoth designed the Harmony units to be free-roaming, independent cleaning units. They use focused energy beams and kinetic pulses to perform their duties. Unfortunately, they now consider all living things as filth that must be cleansed from the world.

Associations[edit | edit source]

The Harmony-Class Drone is identical in form and function to both the Pulse Bombus of Tallon IV and the Atomics. They may have been created to emulate either. The Harmony-Class Drone was preceded in construction by the Diligence Class Drone, which operates in smaller, tighter areas.
