A Scythe is a forearm-mounted weapon used by the Space Pirates in the Prime Series, as a close-quarters combat weapon. The Pirates can readily use them in most circumstances, but some Pirates instead deploy the scythe from a wrist-mounted gauntlet. The Pirates in Metroid Prime 3: Corruption also favour the use of the deployable scythe, in conjunction with the Dash Jet system. These scythes are double-bladed, resembling a classic Zebesian's claws. This allows them to sweep the battlefield with the weapon. The scythes are used by many types of Pirate, including Pirate Troopers, Grenadiers and Militia. The Flaahgra, while not having any relation to the Pirates, also has scythes on its arms.
Weavel the Space Pirate also uses the scythe as an addition to the Battlehammer. In his Alt-Form, the Halfturret, his upper half utilises the scythe as its primary attack. Noxus, another Bounty Hunter, has an Alt-Form named Vhoscythe, which allows him to curl up and deploy a scythe-like appendage.
The Phazon Elite is described in scans as wielding energy bayonets or scythes, though these manifest ingame as glowing extensions of its natural claws.
