Space Pirate Fighter

From Wikitroid, the Metroid wiki

The Space Pirate Fighter is a small fighter ship used by the Space Pirates. It first appeared in Metroid: Zero Mission as a green ship shaped similarly to a tadpole. In the game two of these ships manage to shoot down Samus' Gunship, though Samus herself managed to survive the encounter and then board the Space Pirate Mothership, where she eventually initiated the self-destruct and escape via a fighter in the hangar.

The true name of this fighter is unknown, as it is never stated in the game.

A Space Pirate Frigate with a design nearly identical to a larger pirate fighter appears in Metroid Prime 2: Echoes.

A different kind of pirate fighter appears in Metroid Prime 3: Corruption, where it appears a long, needle-like vessel with a secondary pod attached to the side. The Pirate piloting the ship has tubes sticking from his head and chest into the control consoles, possibly to aid in piloting the vessels.

Corruption also features Pirate Destroyers, which are massive three-pronged ships with Phazon blotches along the main hull. They carry Space Pirate ATCs, and can fire an energy beam capable of damaging Olympus-class capital ships.

In the Metroid e-Manga, fighters resembling rays are used by the Space Pirates to attack Planetary Colony K-2L.
