Atomics are beings composed entirely of energy, which are likely related to the Pulse Bombus which exist on the planet Tallon IV and the basis used for the Harmony Class Drones that were created by the Luminoth of the planet Aether. Samus happened across these organisms in the Space Pirate Mother Ship and the ancient Wrecked Ship on the planet Zebes as well as in the GFS Valhalla and on the planet Bryyo.
