Ke Le Division
From Tardis Wiki, the free Doctor Who reference
The Ke Le Divisions were originally political prisoners of China before being brainwashed into zombie-like soldiers by the use of alien parasites. These were developed by the Chinese government on a parallel Earth with the help of the Unbound Master, who was exiled to Earth. The division was named after "Ke Le", an alias of the Master.
After they'd been freed of the influence of the parasites, the Ke Le divisions looked for revenge against the Master for what he'd done. (AUDIO: Sympathy for the Devil)
