Changeling

Changelings were individuals controlled by the Graske that mimicked a lifeform and sent the real one to Griffoth. They looked almost exactly like the originals, but their eyes flashed a greeny-gold colour occasionally, hinting at their true disposition. The Graske needed to keep the originals alive in order to sustain the changelings. A Graske created Changelings for a Slitheen, a street Urchin, a Mum and a Dad before they were returned home from Griffoth. (GAME: Attack of the Graske)
