Graske
The Graske of Griffoth is a humanoid creature from the planet Griffoth. The Graske is small compared to Humans and has pebbly brown skin and three tentacle-like feature on his head.
The Graske is a conquerer, though unlike other species he does not take a planet by force. Instead, the Graske replaces the inhabitants of the planet with changelings. This process is quick, with the Graske replacing the individual with the changeling in seconds. The originals are then stored on Griffoth in stasis chambers in order to maintain the copy. The changeling can be identified by its glowing green eyes.
The Graske attempted an invasion of Earth, stealing people from various Christmases from across time, which was stopped by the Doctor and one of his companions. (DW: Attack of the Graske)
The Graske was then hired by The Trickster to capture Maria Jackson. The Graske suceeded, but later she managed to escaped. The Graske recptured her again, but then got sent to capture Alan Jackson. Alan fought the Graske and beat it, forcing it to tell him where his daughter went. The Graske later escaped by wriggiling its way out of its bonds. (SJA: Whatever Happened to Sarah Jane?)
