In Yu-Gi-Oh! Yugi Mutou is the titular main
protagonist of the story. In the manga's first chapter, he tries to complete the , one of the seven Millennium Items and an ancient Egyptian artifact, in hopes it will grant his wish of obtaining friends. However, he is bullied by two classmates, Katsuya Jonouchi and Hiroto Honda (Tristan Taylor in the English anime), with the former stealing a piece of the puzzle. When the school's hall monitor Ushio beats them up, Yugi comes to the bullies' defense and is beaten up by Ushio in the process. This causes Jonouchi to return the stolen piece to Yugi's grandfather Sugoroku, who later gives Yugi the piece. Yugi is able to complete the Millennium Puzzle, causing him to become possessed by another person. According to the book of the dead, whoever solves the Millennium puzzle inherits the Dark Games and becomes the guardian of right who passes judgement on evil. The second personality inhabiting Yugi's body, who is referred to as Dark Yugi and, in the manga, is known by epithets such as the , helps Yugi when he is in trouble. He challenges bullies and criminals to
occult judgment games called and enforces to enact justice against evil—the default powers of a Millennium Item wielder. After Dark Yugi defeats Ushio in a game, Yugi becomes friends with Jonouchi. Across the following chapters, he also forms bonds with other characters, most notably his crush, Anzu Mazaki (Téa Gardner in the English anime), who develops a crush on Yugi's alter-ego, and Honda. He also meets
Seto Kaiba, who is obsessed with the card game Duel Monsters. He takes the Blue Eyes White-Dragon from Yugi while at school—the card actually belonging to Yugi's grandfather, Sugoroku Mutou (Solomon Muto in the English dub), who got it from a friend— and swaps it for a fake. After Kaiba destroys the card and psychologically tortures Sugoroku, Yugi and his friends enter Kaiba's Death-T challenge to stop him. Yugi and Kaiba duel, and after Yugi defeats him it results in a rivalry, as Kaiba seeks to have a rematch against both Yugi and Dark Yugi. Shortly after Kaiba's defeat, Yugi receives an invitation to the Duel Monsters tournaments, held by Maximillion J. Pegasus (Pegasus J. Crawford in Japanese versions). To lure him out, Pegasus steals Sugoroku's soul using his Millennium Eye. Yugi and Jonouchi go to the tournament, with the latter seeking to use the prize money to use it for an operation to restore his sister's eyesight. Along with Anzu and Honda, Yugi and Jonouchi defeat multiple duelists, but Yugi is forced to let himself be defeated by Kaiba; the soul of Mokuba Kaiba, Kaiba's brother, had also been stolen. With the help of a former rival, Mai Kujaku (Mai Valentine in the English anime), Yugi manages to reach Pegasus' mansion. Following the tournament, Yugi and Dark Yugi defeat Pegasus. While Pegasus restores the stolen souls, Yugi gives Jonouchi the prize money for the medical treatment of his sister, Shizuka Kawai (Serenity Wheeler in the English anime). Some time after Pegasus' tournament, Dark Yugi learns from Ishizu Ishtar that he was once a Pharaoh, but his memory was erased during a conflict. Shortly after this, Kaiba announces his own tournament – Battle City – where the losers must give the winner their most valuable card. A group of hunters led by Ishizu's corrupted younger brother, Marik, are set to challenge Yugi, having a vendetta against the Pharaoh. In one duel, Yugi is faced by Slifer, the Sky Dragon (Osiris in Japanese versions): one of the three Egyptian God Cards which are recognized as the three strongest cards. Yugi defeats Marik's hunter and earns Slifer, which he later uses to defeat Yami Bakura and confront Kaiba in a rematch, who uses the second God Card: Obelisk the Tormentor. Yugi ultimately defeats Kaiba and obtains Obelisk. In the finale, Yugi faces Marik's own darker alter-ego, who possesses the third God Card: The Winged Dragon of Ra. Using a card Kaiba had given him, Yugi defeats Marik, obtains Ra, and becomes the tournament's champion. During the final story arc of the manga, Dark Yugi uses the three God Cards to learn of his past, and is transported to an alternate version of his life where he lived as a pharaoh. During this time, the Pharaoh clashes with Yami Bakura while Yugi and his friends search for a way to aid him. At the end of the manga, it is revealed that his name as Pharaoh was , who sealed his soul into the Puzzle along with the Great God of Evil, Zorc Necrophades. The group is able to defeat Zorc and his avatar, Dark Bakura. After this, Yugi engages Atem in a final duel to help him move on to the afterlife.
