A clone template, also referred to as a donor, an original host, or the Prime Clone, 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. Sidious was also the template of his cloned son, a failed strandcast who was engineered by the Sith Eternal cult on Exegol.
