The origin of Duel Monsters is revealed! Using the magic of the Millennium Necklace, Egyptian historian Ishizu Ishtar shows Kaiba how Duel Monsters was played millennia ago in the form of Shadow Games! The ancient games have been resurrected in modern times, along with three almighty beasts of devastation – the Egyptian Gods, whose powers are far more powerful than Exodia! Now they are duel monster cards and when Ishizu gives Kaiba Obelisk The Tormentor, his greed for power overwhelms him and he is determined to get the legendary God Cards, even if it means destroying Yugi.
