Darth Maul was a Dathomirian Zabrak Sith lord, the first known apprentice of Darth Sidious and Obi-Wan Kenobi's archenemy. Maul was taken by Sidious from his home and separated from his two brothers, Savage Opress and Feral, and trained to be a weapon fueled by the dark side of the Force. Before the Clone Wars, he was bisected by Obi-Wan Kenobi during the Trade Federation invasion of Naboo and presumed dead after killing Obi-Wan's master, Qui-Gon Jinn.
However, despite his bisection, Maul had survived his encounter with Kenobi and escaped to Lotho Minor, where he remained for the next ten years in exile, losing his memories as he was slowly driven mad. Years later, his brother would come to locate him, and together they caused havoc across the galaxy.
