Darth Vader

Darth Vader is a Sith Lord and apprentice of Darth Sidious, aka Palpatie, or the Emperor. He used to be a Jedi called Anakin Skywalker but he turned evil when he realised its cooler. His master used to be Obi-Wan Kenobi, but he later kills him onboard the Death Star. Darth Vader used to look normal but in his first duel with his former master he was badly burned and lost all his limbs, so he became a cyborg to stay alive.
