The plan continued apace for the remainder of the war, although the Jedi High Council had grown increasingly wary of the Chancellor's motives. Fives told what he knew to his Jedi superior Anakin Skywalker, but before the clone could prove it, he was killed by clone shock troopers of the Coruscant Guard. Furthermore, he discovered to an extent Supreme Chancellor Sheev Palpatine's involvement in the conspiracy and attempted to assassinate him. On the galactic capital Coruscant, however, he learned that the chips conditioned the clones to become hostile against the Jedi. The incident led ARC trooper CT-5555 'Fives' to conduct his own investigation into the matter, believing the incident to be a Separatist plot against the Republic. In secret, Order 66 was the means by which the Sith intended to bring about the long-awaited fall of the Jedi Order.ĭuring the Clone Wars, the Sith agenda was progressing relatively unnoticed until a premature activation of Order 66 resulted in the death of General Tiplar at the hands of CT-5385 'Tup,' a defective clone whose malfunctioning chip caused him to turn against his Jedi officer. The Kaminoan scientists who designed the clone troopers believed it was only to be used as a contingency protocol against renegade Jedi. The order was programmed into the Grand Army clone troopers through behavioral modification biochips implanted in their brains, making it almost impossible for the clones to disobey the command to turn against their Jedi Generals.

Order 66, also known as Clone Protocol 66, or simply ' the Order,' was a top-secret order identifying all Jedi as traitors to the Galactic Republic and, therefore, subject to summary execution by the Grand Army of the Republic. ' Execute Order 66.' ―Darth Sidious - Listen ( file info)
