Maul

Maul, formerly known as Darth Maul, was the formerly Sith Apprentice of Dark Lord of the Sith Darth Sidious. In the Battle of Naboo, he killed the Jedi Qui-Gon Jinn, but he was struck down by Jedi Padawan Obi-Wan Kenobi. He was believed dead for almost 11 years. However, he was alive, hidden in Lotho Minor, but later, his brother Savage Opress rescued him. He took Opress as an apprentice and established himself as a crime lord, controlling the Pikes, Black Sun, and the Hutt clan.

At the end of the Clone Wars, he was overthrown by the Galactic Republic and Ahsoka Tano, capturing him alive. However, he witnessed the Order 66 with his own eyes, after Tano's clones tried to kill her. He escaped, and formed the Crimson Dawn. Later, his desire for revenge was his death. He tracked down the Jedi Kenobi to Tatooine, where the Jedi was exiled, and was killed by him.
