501st Legion/Legends

The 501st Legion (a.k.a. Vader's Fist), was a legion of elite soldiers created by then Chancellor Palpatine. During the Clone Wars, the 501st Legion accompanied Anakin Skywalker to the Jedi Temple to begin the Great Jedi Purge as commanded by Order 66. After the fall of the Republic and the rise of the Empire, the legion's memebers were replaced by the best of the stormtroopers. Due to their early work with Anakin/Vader, the legion became known as Vader's Fist. The mere metion of the "Fighting 501st" put fear into the hearts of all, especially those hated by the Emperor. Even after the fall of the Empire, the 501st continued operation, working side-by-side with Luke Skywalker and Mara Jade Skywalker on the remains of Outbound Flight.
