"Where are my pork rinds??!?!?!"
Maul was a ZabrakSith Lord, and the first apprentice of Darth Sidious. He was able to kill a couple of Jedi before the blockade of Naboo, but it was during that crisis that he revealed to the Jedi that the Sith had returned.What actually had happened was the Sith had been dormant for over a thousand years, never truly wiped out as the Jedi had though. They'd remained unseen (except of course for Darth Meeen'sHappy Bunny Sith Apprentice Competition) by the Galaxy until Qui-Gon Jinn was attacked by Maul on Tatooine. Sidious had pushed the Trade Federation into invading the planet Naboo, but two Jedi ambassadors Sidious pretended to not have expected showed up and rescued the Queen before she could sign a treaty legitimizing their occupation. After several other snooze-inspiring events, Maul came to Tatooine searching for her and aching to whoop some Jedi butt. He engaged Qui-Gon in the desert, but the Jedi escaped.
Maul showed up next on Naboo, sneering at the Trade Federation and anticipating the return of the Jedi. When they did show up, he made the best entrance in any Star Wars film, and entered a playful duel with Qui-Gon and his apprentice, Obi-Wan Kenobi. Maul's boots had some words with Kenobi's face, and Maul was able to seperate the pair long enough to run Jinn through with his double bladed Lightsaber. After puffing his chest up through a laser shield, Kenobi was able to charge in and take Maul on by himself, ultimately doing a flip move and halfing Maul's height.
Maul never came back. At all. Ever. Not as a cyborg and not as a clone. He was dead, and it was surprising for him. He was succeeded by Darth Tyrannus.
