2003 General Grievous

2003 General Grievous was a villain in Star Wars. He first revealed himself to the Republic in the Battle of Hypori. During the battle, even the Jedi that were stationed there were overwhelmed by the tactics of the new unknown General controlling the droid forces and were pinned down in a Republic cruiser crash site. When the Jedi were completely surrounded by a droid army, Grievous, who still had not been seen, offered the Jedi two options, surrender and die or face him. When the Jedi did not reveal themselves Grievous proceeded to battle them. In the end, three of the seven Jedi were rescued by a team of ARC Troopers led by Captain Fordo, the rest were killed by Grievous leaving a major impression on the Republic.
