Galvanic Accelerator Cannon

The Galvanic Accelerator Cannon is the weapon used by Space Pirates in all of their appearances. The appearance of the shot has varied throughout the series, and always appears differently.

Super Metroid featured a shot with the same sprite as the Plasma Beam, but colored yellow. Metroid Fusion and Metroid: Zero Mission had a long shot of green plasma. Metroid Prime and Metroid Prime 2: Echoes had a small yellow shot while Metroid Prime 3: Corruption had a shot similar to a Phazon Unit.

The Galvanic Accelerator Cannon is absent in Metroid Prime Pinball; instead, the Pirates use Missiles.
