Zebesian Pirate Ship

The Space Pirate Fighter is a small fighter ship used by the Space Pirates. It appeared in Metroid: Zero Mission as being green and shaped similarily 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.
