A close-up of an Airthorn.

An Airthorn is an aerial enemy from Metroid Prime 2: Echoes. A flock of Airthorns is observed in one room only, the Dark Transit Station, and cannot be scanned in normal gameplay for the reason being that Samus is moving through a tunnel in Morph Ball and cannot access her Scan Visor when they pass by. When accessing a Secret World in the same room, however, Samus, now in her bipedal form, can scan the flying mechanoids and read their information. Airthorns are not stored in her logbook since they are not meant to be scanned, though the well-detailed information suggests they were originally planned to be.

These mechanisms were created by the Luminoth during the war against the Ing to patrol airspace before they went rogue to work for the latter. They seem to possess some sort of Dark Energy-based shield, given the fact they fly through the atmosphere of Dark Aether unhindered. Airthorns were originally programmed to inform their creators of any possible danger, much like the Sentinel Crystals and Dark Sentinel Crystals, though the latter two were designed to watch over ground terrain and still serve their only active Luminoth master, U-Mos.

Logbook entry

The Luminoth made the Airthorn to patrol local airspace. The small, speedy machines were a boon to the war effort until their programming failed. Now rogue, they serve the Ing as fiercely as they served their creators.
