In the sequel trilogy (2015–2019), the upgraded stormtroopers serve the First Order under the leadership of Supreme Leader Snoke and his commanders, most notably Kylo Ren, General Hux, and Captain Phasma. Despite this, later stormtroopers are established as recruits at the time of the original trilogy, only a few stormtroopers are clones, with the only known legion to still contain a significant number of clones being the 501st Legion, aka 'Vader's Fist'. The prequel trilogy (1999–2005) establishes their origin as the Galactic Republic's clone troopers, clones of the bounty hunter Jango Fett, used by Supreme Chancellor Palpatine to 'win' the Clone Wars and later to take over the government and exterminate the Jedi. Introduced in Star Wars (1977), the stormtroopers are the elite shock troops/ space marines of the Galactic Empire, under the leadership of Emperor Palpatine and his commanders, most notably Darth Vader and Grand Moff Tarkin, during the original film trilogy (1977–1983). A stormtrooper is a fictional soldier in the Star Wars franchise created by George Lucas.
