American McGee's Alice. He is ruler of the Red Chess pieces in the Pale Kingdom.
He captures the White Queen and has her decapitated, so it is easier to destroy the remaining White Pieces (the only force willing to rebel in Wonderland) and enforce the Red Queen's rule. Alice confronts and fights the Red King at the center of the Red Castle and defeats him. The Red King's strongest weakness seems to be the Ice Wand, which can be used to slow down his movement. After the king's defeat, Alice uses a White Pawn she brought with her to revive the White Queen.
