Silla

An ancient creature accidentally unearthed on Malastare during an intense battle of the Clone Wars, the zillo beast was a monster of legend. The enormous animal proved to be nearly invulnerable to Republic weaponry, prompting intense interest from then-Chancellor Palpatine. At his order, the creature was incapacitated and transported to a secure research facility on Coruscant, before it broke free and terrorized the capital. In the era of the Empire, Emperor Palpatine's scientists continue to work on harnessing the species' natural gifts, with disastrous consequences. On one occasion, an Imperial craft carrying a modified version of the creature crash-landed on the world of Silla, leaving the modified zillo to blindly hunt for power sources, gulping at energy conduits to propel its rapid growth, and feasting on one of the planet's solar farms.

Royce Hemlock once served the Galactic Republic, but his penchant for experimentation eschewed the ideals of that democracy. After the rise of the Empire, Doctor Hemlock enjoys a new title as head of the Advanced Science Division wielding the power to control secret medical trials in cloning technology at the Mount Tantiss facility on Wayland. Working on secret projects of great interest to the Emperor himself, Hemlock has amassed a veritable army of clone prisoners, unwilling subjects for his invasive procedures.

Dr. Emerie Karr blends into the crowd of Imperial medical professionals working inside the secret labs at Mount Tantiss on the world of Wayland. A diligent worker who seems to have compassion for the clone prisoners on her exam table, Dr. Karr believes that resisting the Empire's experimentation is futile. But she has more empathy for her test subjects than some, owing to the fact she is also the result of Kaminoan cloning technology, a sister to Omega and the other clones.

Once the lanky Prime Minister of the remote world of Kamino, Lama Su oversaw the creation of the Galactic Republic's first clone armies. That effort gave his storm-swept homeworld influence in the Republic, but also made it a target of the Separatist military. At the dawn of the new Empire, Lama Su remained in power until the Imperial bombardment destroyed Tipoca City. Imprisoned at Mount Tantiss, Lama Su continued to cooperate with his Imperial captors, exposing Omega as the key to controlling the scientist Nala Se.

Hunter is a strong and stoic soldier with a special set of skills. As the leader of the Bad Batch,—technically known as Clone Force 99, a group formed as the result of Kaminoan experiments to create a specialist unit of clone commandos—Hunter has extraordinarily keen senses that give him an edge when tracking down his targets. But his allegiance has been tested in the aftermath of Order 66, and his duty is now to Clone Force 99 alone, including the newest member, young Omega.
