K'rokk

Professor K'rokk was the Mobox president of Cornucopia's Assassins Alliance. When a rad-storm shut down Cornucopia's spaceport, K'rokk helped Granny Solasta take over. With the unwilling help of the Eleventh Doctor, the criminal leaders broke into the Ziggurat of Cornucopia, but the Doctor manipulated their greed into making them fight. He was killed by Granny, who sealed his mouth shut with quick-dry cement, making him explode, as he was a Mobox. (COMIC: The Cornucopia Caper)
