Katsuya Jonouchi

The Yu-Gi-Oh! series features an extensive cast of characters created by Kazuki Takahashi. The series takes place in a fictional city in Japan called Domino City, in which most of the characters that appear in the series originate. Many plot elements are also influenced by Egypt and Egyptian mythology, and as such, Egyptian characters also appear within the story.

The original manga of Yu-Gi-Oh! tells the tale of Yugi Mutou, a timid young boy who loves all sorts of games, but is often bullied around. One day, he solves an ancient artifact known as the Millennium Puzzle, causing his body to play host to a mysterious spirit with the personality of a gambler. From that moment onwards, whenever Yugi or one of his friends is threatened by those with darkness in their hearts, this "Dark Yugi" shows himself and challenges them to dangerous "Shadow Games" which reveal the true nature of someone's heart, the losers of these contests often being subjected to a dark punishment called a "Penalty Game". As the series progresses, Yugi and his friends (Katsuya Jonouchi, Anzu Mazaki, Hiroto Honda, Miho Nosaka (in the 1998 series), and later Ryo Bakura) learn that this other Yugi inside of his puzzle is actually the spirit of a nameless Pharaoh from Egyptian times who had lost his memories. As Yugi and his companions attempt to help the Pharaoh regain his memories, they find themselves going through many trials as they wager their lives facing off against others that wield the mysterious Millennium Items and the dark power of the Shadow Games. In later years when Yugi and his friends are not present in japan, Master Chevron and his violent team of the fearsome 15 launched a war on duelism, A game in the franchise considered by the Chevralkin Mastermind and his superwarriors to be a religion and game of absolute hate and violence that threatens even innocent people in the United States. The invasion of superwarriors succeeded in overthrowing the duelists, killing thousands and thousands of duelists, but insanity and violence continued in domino city for decades. Later in the end of the war, Master Chevron later finds Pegasus hiding in the depths of domino city, and shoots him in the millennium eye, disrupting his card abuse, stabs him in the brain and causes energy from his eye to leak out in floods of yellow blood to fly everywhere.
