'''Atem''' is an ancient Egyptian pharaoh who had sealed his own spirit/soul within the mystical [[Millennium Puzzle]]. His spirit then took on the identity of [[Yami Yugi]], which resided in the body of [[Yugi Muto]], after Yugi solved the [[Millennium Puzzle]]. He is the center piece of the ''Yu-Gi-Oh!'' series, and is the reason for ''allmost'' of the events that transpired during the series. With the exception of the KC Grand Prix.
