Gargoyles & Pack Chess Set
The Gargoyles & Pack Chess Set is a chess board with custom-made pieces. The white pieces resembled the Manhattan Clan and the black pieces resemble the Pack. David Xanatos and Fox played a game of chess against each other where they manipulated and maneuvered their pieces against each other. But while the physical chess set did exist, the true pieces were the actual Manhattan Clan and Pack. Fox guided the Manhattan Clan to victory while Xanatos manipulated the Pack until he was checkmated.
But Xanatos wasn't unhappy to lose the game, it cemented his belief that in Fox he had found a true equal. ("Upgrade")
