When you first arrive in the Wrecked Ship, you can spot Atomics trapped within the glass casings, spinning wildly. After the ship is activated, they will break free. However, there is one room in the ship where the Atomic is still functioning properly within its glass case.
In Metroid Zero Mission, Atomics could shoot beams of electricity. Atomics also appeared in Metroid Prime 3 on Bryyo and in G.F.S. Valhalla. Atomics also resemble the Pulse Bombu from Metroid Prime.
