YUGI MUTOU
First Appearance: Episode 1 - The Heart of the Cards Favorite Card: Dark Magician
Yugi Mutou is a spikey-haired kid who attends Domino High School. He likes all kinds of board games and his grandfather, Sugoroku Mutou, owns a game shop. Yugi knows how to play many of the games in his grandpa’s store. In persona, Yugi is shy and lacks confidence to communicate with others. This makes him a frequent target to a countless number of bullies, gangsters, thieves, and other bad guys. His grandfather gave him a long lost Egyptian puzzle knowing that the magic within the puzzle may help Yugi out. This 3-D pyramid-shaped puzzle called “The Millennium Puzzle” is an ancient artifact from Egypt that gives special powers to whomever wears it. This puzzle is a part of the “Seven Sennen Sets”. After Yugi completes it, his life changes. Although Yugi is weak in his normal stage, he does have many friends that stand by his side and protect him. Tea Gardner, Tristan Taylor, Mai Valentine, and Ryou Bakura are the names of some his friends and classmates. Joey Wheeler, who is possibly Yugi’s best friend, always fights for Yugi.

As a reward for the game, Seto and Mokuba became his adopted sons. Seto’s entire life is obsessed with finding one special card called the Blue Eyes White Dragon. This is one of the strongest monster cards in the game. When Seto finds out that Yugi’s grandpa has a BEWD card, he offers his entire collection in exchange for it. Grandpa refuses and Seto tries to take the card from Yugi. Later on, Yu-Gi-Oh beats Kaiba at a game and takes back the card for Yugi.
