As the Jedi hero Anakin Skywalker, he fought alongside his master Obi-Wan Kenobi during the galaxy-wide Clone Wars, but was slowly seduced to the dark side by Darth Sidious. After helping Sidious kill Jedi Master Mace Windu, he swore allegiance to the Sith and was given the name Darth Vader before setting out to destroy all Jedi left on Coruscant. After being sent by Sidious to assassinate the Separatist council members on Mustafar, Vader was badly injured in a duel with Kenobi, resulting in the loss of his remaining organic arm, both legs and severe burn injuries. He was saved by Sidious, and encased in a black suit of armor with extensive cybernetics which kept him alive. As the Galactic Empire was established and continued to grow, Vader became the Emperor\'s immensely feared second-in-command and was given the task of finding surviving Jedi and the Rebel Alliance\'s base. After the destruction of the First Death Star, Vader was charged with tracking down the Rebel Alliance and destroying their headquarters.
