General Grevious (voiced by Mathew Wood) is the cyborg Supreme Commander of the Droid Armies and is a villain in the Jaden's Adventures of Star Wars saga. Grevious captured Palpatine as part of a secret plot. Anakin, Obi-Wan, Jaden and his friends were sent on a mission to rescue the Chancellor, and stop Grevious and Dooku. They managed to kill Dooku, but Grevious got away, making him the Republic's top priority. Jaden and Obi-Wan both took the job of destroying Grevious, and challenged him to a duel. He was trained in the Jedi arts, but was defeated in the end. In Legend, General Grevious was able to take on his own Five Jedi, and not get hurt.
