The Pulse Bombu is a creature in Metroid Prime comprised entirely of raw electricity. Resembling three yellow-green spheres attached to a cyan nucleus, it glows as it floats through the air. It periodically releases explosive segments from its body and lacks any intelligence other than an instinctive attraction to charged energy sources.[2]

Samus encounters Pulse Bombus in the Chozo Ruins, Phendrana Drifts and the Phazon Mines on Tallon IV. While they don’t actively attack, the explosive segments they shed pose a hazard. Additionally, they are attracted to sources of charged energy and will instinctively fly toward Samus if she uses her Charge Beam, harming her on contact. Their energy-based nature makes them immune to all weaponry except the electricity of the Wave Beam, but this also means that they will be instantly destroyed if they touch water.

There is a variant known as Scatter Bombu, that lurks inside of tunnels. Invisible Pulse Bombus that can only be seen with the X-Ray Visor also exist.

A robot created by the Luminoth appears in Metroid Prime 2: Echoes, known as the Harmony Class Drone. It behaves and is similar in appearance to the Pulse Bombus.

Atomics, creatures very similar to Pulse Bombus, appear in Super Metroid, Metroid: Zero Mission and Metroid Prime 3: Corruption.
