The Game Plan Class of the Titans : Season 2 Episode 18

As the Christmas holiday draws near, Zeus is captured and challenged by Cronus to a chess game. The stakes are high though as Zeus' chess pieces are actually of the seven heroes. The horrible thing is that, if one of the heroes get check mated on the board, they get check mated in real life too! As the heroes race around to find a Cornicopia that grants wishes so they can get Zeus back, Zeus is playing for their lives.
