The Grand Inquisitor, introduced simply as The Inquisitor and also known as the Master of the Inquisitorius, is a fictional character in the Star Wars franchise. Voiced by Jason Isaacs, he is featured as the main antagonist of the first season of the animated series Star Wars Rebels (2014–2018), after being introduced as a Pau'an Temple Guard in Star Wars: The Clone Wars (2008–2014; 2020), who defects from the order during Order 66 and is tasked to hunt down all remaining Jedi by Darth Sidious in its aftermath. Following his suicide, the Grand Inquisitor's redeemed spirit — The Sentinel — aids Kanan Jarrus against the Inquisitorius, knighting him as a Jedi, before being enslaved by the Sith as a Temple Guard once more.
