Yugi Mutou completes the Millennium Puzzle, a 3,000-year-old Egyptian artifact. The spirit within the puzzle — an ancient pharaoh with no memory of his name — merges with Yugi and activates Shadow Games against those who harm the innocent.
Yugi faces Maximillion Pegasus in the Duelist Kingdom final. Pegasus reads minds with his Millennium Eye. Yugi and the Pharaoh use a mind-shuffle technique — swapping control mid-duel — to deny Pegasus's advantage. The duel defines the series' psychological dimension.

Yugi battles the evil persona of Marik Ishtar in the Battle City final. The Shadow Game kills every life point lost by eliminating part of the loser's real soul. Yugi wins by sacrificing his own life points strategically, forcing Marik to choose between losing and letting his good self die.
The Pharaoh's true name is recovered, his memories restored, and he faces Yugi in a final duel to determine if he is ready to move on to the afterlife. Yugi defeats his partner and best friend. The Pharaoh thanks him and passes on. Every character that mattered watches him go.
