"We modified their genetic structure to make them less independent than the original host."
"And who was the original host?"
"A bounty hunter called Jango Fett."
―Lama Su and Obi-Wan Kenobi[src]

A clone template, also referred to as a Prime Clone or an original host, was the genetic source upon which a clone was created. During the late era of the Galactic Republic, the human bounty hunter Jango Fett became the template of an army of clone troopers secretly built on the planet Kamino. Darth Sidious, the Dark Lord of the Sith and Emperor of the Galactic Empire, engineered a clone of himself to serve as a vessel for his essence, thereby allowing him to survive his own death.


"The sample doesn't match anything found in the Jango Fett genotype. Furthermore, it is not even completely organic. It is foreign to the body. Someone implanted it there."

Cloning was the process of using a living organism's genetic code as a template in order to create a clone of the original source. Without alterations to the template, the clone would be an exact duplicate of its progenitor. By manipulating the genetic structure of the template, a clone's genotype could be modified for various purposes such as growth acceleration and greater docility.[3]


"I have successfully made contact with the Prime Minister of Kamino. They are using a bounty hunter named Jango Fett to create a clone army."
Obi-Wan Kenobi, reporting to Mace Windu and Yoda[src]

Prior to the Clone Wars, Obi-Wan Kenobi discovered that the bounty hunter Jango Fett was the template of an entire clone army.

During the final years of the Galactic Republic, the Sith Lord Darth Tyranus recruited Jango Fett—a human bounty hunter—as the genetic template of a secret clone army. Fett would come to live on the planet Kamino where the Kaminoans, a species of skilled cloners, extracted samples of his DNA in order to create the first generation of clone soldiers for the Republic. In addition to the mercenary's financial compensation, Fett requested the creation of an unaltered clone of himself. The result was Boba Fett,[3] a clone whom Jango regarded as a son.[4]


Clone troopers were genetically identical, having been engineered from a single template.

The Kaminoan scientists modified Jango Fett's genotype for the purpose of producing loyal clones at an accelerated rate. With the exception of Boba, who was grown through pure genetic replication, the rest of Jango's clones were designed to age at twice the speed of birth-born humans.[3] To ensure loyalty and obedience in the clones, the Kaminoans installed an inhibitor chip within the brain of every Fett clone.[5] The chip's official purpose was to diminish the aggressive traits of the clone template so that the clones would be more compliant with orders.[6] Although the Kaminoans believed that the chip was actually meant to serve as a contingency against rogue Jedi,[7] the true nature of its design would compel the clones to execute Order 66—a secret protocol conceived by the Sith in their plot to destroy the Jedi Order.[8]

Following the death of Jango Fett at the First Battle of Geonosis in 22 BBY,[3] the Kaminoans were forced to conserve their remaining samples of the Fett genome in order to grow more clones for the newly-formed Grand Army of the Republic. Prime Minister Lama Su believed that younger clones were less efficient because of Fett's untimely demise. As such, he recommended that the Jedi procure another template for the creation of new clones.[9]


Darth Sidious survived death by transferring his soul to a clone of his original body.

Shortly after the discovery of the Zillo Beast on Malastare, the Republic Military transferred the creature to the galactic capital of Coruscant for scientific study. In the aftermath of the beast's escape and subsequent death, Supreme Chancellor Sheev Palpatine ordered Doctor Sionver Boll to utilize its corpse as a clone template.[10]

Darth Sidious—Dark Lord of the Sith and Emperor of the Galactic Empire—was the template for multiple genetically engineered clones created on Exegol by the Sith Eternal. After his death in the Battle of Endor, his spirit was thrust into an imperfect clone of his, making the subject quickly decay. After this, his Sith cultists produced even more clones, among them his "son" who fathered a daughter, Rey. The decayed clone body he possessed was destroyed by Rey, along with the other clones when the Sith Citadel collapsed, in the battle of Exegol, killing Sidious indefinitely.[2]
