The Chess Queen minifigure was a giant chess piece part of Professor McGonagall's transfigured chessboard. It was the fourth task to get by that was guarding the Philosopher's/Sorcerer's Stone, and was part of the white chess team. Instead of a regular minifigure head, it has a cylindrical piece and, instead of normal minifigure legs, a slope piece for her legs. She wields a white staff and a Belville crown. She is the chess figure that nearly killed Ron.
