Dark Yugi Fanclub

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 Dark Yugi, 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.
