History
Reminiscent of the Cybermen created by John Lumic on the Earth known as Pete's World, the Cyber-Slitheen were created when Lumic Slitheen upgraded his entire family. Though their emotions were removed, the Cyber-Slitheen retained their goal to make lots of money. However, since their upgrade they refused to deal in gold. (NOTVALID: Time Warped!)
