Space Pirate Boarding Pod

From Wikitroid, the Metroid wiki

Boarding Pods are crude starships (even by their standards) used by the Space Pirates to board enemy ships. They consist of a propulsion drive, cockpit, and a nose cone packed with heavy explosives. The pilot attempts to ram the enemy and detonate the explosives, trying to create a breach which the crew of the pod can enter through. However, the pod and crew are considered expendable, and they are not well protected. This is backed up by a scan in Metroid Prime 3: Corruption, which says that the Boarding Pods' Space Pirate nickname of "Space Coffin" is well earned. Samus find them while the G.F.S. Olympus is under attack. The ship appears to be partially organic. They also appear floating outside the G.F.S. Valhalla, and one holds the Leviathan Command Codes in the depths of the ship.
