In the Star Wars universe, the Clone Wars is a series of conflicts between the Galactic Republic and a Separatist movement; the name comes from the Republic's army, which consists of clone troopers created from the genetic material of bounty hunter Jango Fett. Clone Force 99, also known as "The Bad Batch", is a unique squad of clones with genetic mutations that were introduced in the series Star Wars: The Clone Wars. These mutations allow most of the Bad Batch to resist Order 66, which brings the Clone Wars to an end by triggering secret programming in the clones that forces them to execute the Jedi and become obedient to Emperor Palpatine and the new Galactic Empire. Star Wars: The Bad Batch follows the titular team as they become mercenaries on the run in the early days of the Empire. They are joined by Omega, a young female clone of Jango Fett. The series also tells the stories of other clones following the end of the Clone Wars, including how some begin to question Order 66, how the Empire phases out the clone army in favor of conscripted Stormtroopers, and how Imperial cloning resources are re-directed to "Project Necromancer"—a secret project to clone Palpatine that helps explain that character's return from death in the film Star Wars: The Rise of Skywalker
