is the protagonist of the manga and anime series Yu-Gi-Oh!, and is featured in almost every chapter and episode of the series. He is a young boy whose body becomes inhabited by the spirit of an Ancient Egyptian pharaoh named when he completes the Millenium Puzzle.
His usual outfit consists of the standard male Domino High School uniform, although he wears a closed buckled leather collar. Unlike the other characters, he almost always wears this and is only occasionally seen wearing a different outfit. During his duels in the Battle City arc, he (under the influence of Atem, who was then called "The Pharaoh," as his name was unknown at the time) would wear his jacket like a makeshift cape. His extremely extravagant hair consists of multiple layers; while his fringe is made up of long, crooked blond locks, the main body features seven large, black spikes with magenta-rimmed edges. He wears the Millennium Puzzle on a chain around his neck. In the first series anime, the chain is replaced with a rope. Yugi himself is wide-eyed and boyish, sporting large eyes and cartoonish features. Upon becoming the Pharaoh, his features become accented and "serious-looking." In the manga (post Volume 7) and in the second series anime, he often wears a KaibaCorp Duel Disk on his left arm.
After being given the pieces of the ancient Egypt artifact called the Millennium Puzzle by his grandfather, Yugi spent eight years attempting to solve the puzzle. When he eventually succeeded, he unknowingly undid a binding spell created by the ancient Egyptian pharaoh Atem, who had sealed the magic of the Shadow Game in the Puzzle and the other Millennium Items thousands of years ago in order to stop the victory of the evil demon Zorc Necrophades. The Pharaoh had bound the spell with his own name and sealed his own soul within the puzzle; when Yugi solved the puzzle, both the magic of the Shadow Games and Atem's soul were released, and Yugi's body became host to the spirit of Atem.
At first, Yugi has no awareness of the presence of this second personality within himself, which emerges in times of stress, takes control of his body, and punishes evildoers that threaten Yugi and his friends, leaving Yugi himself with no memory of the events. At the time, this personality - the true nature of which had not yet been divulged to the characters in the story - is referred to in Japan as , in reference to the particularly sinister mannerisms of the pharaoh at the time, and the vicious punishments he meted out, including turning losing or cheating opponents insane. With the introduction of the Duel Monsters card game as the main fixture of the Yu-Gi-Oh! storyline, the "Dark Yugi" moniker no longer seemed appropriate, as the character ceased to be the sinister, vengeful figure of earlier installments. Now, he would emerge from the Millennium Puzzle to take control of Yugi's body for the purposes of dueling others in the card game; rather than entirely supplanting Yugi's personality, as he had before, there was a degree of interplay between the two, wherein Yugi was aware of his surroundings and the events of the duel, but unaware of the presence of the pharaoh guiding his hand.
