Sylven

Sylven was a robot of the Fatkat Corporation, programmed to protect Pholonius Ginn. It appeared on Earth when the Tenth Doctor cornered Ginn, who was attempting to sell off a collection of the Seven Wonders of the World and again when Pholonius Ginn was exposed as the power behind the Fatkat Corporation, having deposed the director Trongus Squum.(COMIC: Minus Seven Wonders)
