Maul

Maul, formerly Darth Maul, was a Force-sensitive Zabrak male from Dathomir. He served as the apprentice of Darth Sidious before he was thought to be killed when he was cut in half by the Jedi Obi-Wan Kenobi. However, Maul survived and hid on a junkyard planet for many years before he was found by Savage Opress and given new legs. He set out on a mission to destroy Obi-Wan. He was killed for good by Obi-Wan Kenobi decades later.
