Clone Troopers are cloned soldiers originating from the Star Wars prequel trilogy. They were created in secret on Kamino, and discovered by Obi-Wan Kenobi when he followed a clue to a murder. These clones, being genetically engineered for battle, with accelerated growth, were all cloned from Jango Fett, a well-known and feared bounty hunter.
Clones served in the GAR, the Grand Army of the Republic, alongside the Jedi. When Darth Sidious commenced Order 66, the control chips within the troopers activated and the clones fired upon and killed the Jedi.
The Clone Troopers are loyal and obedient, and they usually follow orders without question from high-ranking officials such as Anakin Skywalker and Obi-Wan Kenobi. Despite this, most clones, like Rex, have individual traits and personalities, and do not always follow orders without question.
Unlike the Stormtroopers, the Clone Troopers are skillful soldiers, being very good at aiming for their targets and have been trained in hand-to-hand combat.
Due to them having inhibitor chips implanted into their brains during their growth cycle, the moment the Clone Troopers hear the words; "Order 66", their individual identities will be completely overridden and they will unwillingly turn against their Jedi comrades and kill them, having no control of their actions.
Attack of the Clones
The Clones were an army being made on Kamino for the Galactic Republic. Jedi Obi-Wan Kenobi found them while looking for a bounty hunter, who was their genetic template named Jango Fett. Later on the army were collected by Jedi Master Yoda, who brought them to Geonosis to assist the Jedi in a rescue attempt. They fought the Battle of Geonosis, in which they won, and the Clone Wars began.
Revenge of the Sith
Near the end of the Clone Wars, the Clones were assisting all Jedi on different planets. After Anakin Skywalker's turn to the Dark side and the death of Mace Windu, Palpatine ordered them via hologram to execute Order 66: kill all Jedi. Most Jedi were wiped out successfully and the Clones became Stormtroopers under the newly formed Galactic Empire.
The Clone troopers played a major part in the series, appearing in nearly every episode. The two most main Clones in the show were Captain Rex and Commander Cody. Other clones were also introduced such as Fives, Echo, Heavy, Bly, Fil, Jessie, Waxer, and Boil. The Clones were known to be killed a lot such as Heavy, who sacrificed himself in an explosion, and Fives, who was executed after finding out about Order 66.
All of the clone troopers are voiced by Dee Bradley Baker, with the exception of a young Boba Fett, who are all voiced by Daniel Logan instead. In the prequel films, they were all played by Temuera Morrison.
