Katsuya Jonouchi is a fictional character in the manga and anime series Yu-Gi-Oh! He is known as Joseph "Joey" Wheeler in the English-language anime and video games.
In the first seven volumes of the original manga, Jonouchi's hairstyle changes drastically. Originally featuring two large fringes in front of his ears, the hairstyle changes to a sporadically arranged and unrealistic hairstyle. Jonouchi's first color appearance depicts him with medium brown hair and black eyes. Subsequent appearances lighten the hair color to dirty blond and blond. His eyes are portrayed as brown or hazel.
In the first series anime, Jonouchi's hairstyle does not change, and the sporadic hairstyle colored in a bright blond style is used. His eyes are brown.
In the second series anime he has dirty blond hair in the sporadic hairstyle and dark brown eyes. His usual outfit from the second series anime consists of a long green open jacket with a raised collar, a white T-shirt underneath and blue jeans. He often carries a KaibaCorp Duel Disk on his left hand.
16-year old Jonouchi, who is in class 1-B at Domino High School, is a hothead and his mouth gets him in trouble often. Jonouchi starts out as a street thug and hangs in Hirutani's gang for long periods of time when he is in middle school. He also used to be a bully for young Yugi. He becomes best friends with Yugi Mutou, who melts his tough-guy exterior to reveal his true nature. Jonouchi's friendship with Yugi is a key element of the series as a whole and Yugi has credited his friendship with Jonouchi as one of the main factors that allowed Yugi to become stronger throughout the series. His other two good friends are Hiroto Honda (Tristan Taylor) and Anzu Mazaki (Téa Gardner). In the first series anime, Miho Nosaka is also one of Jonouchi's friends.
Jonouchi from the first series anime
In the manga, Jonouchi is poor, due to his father's gambling addictions and alcoholism. Jonouchi goes to great lengths to repay his father's debts, such as working at multiple jobs (he was the "lone paperboy" in middle school, meaning that he was one of the few that were permitted to work while going to school) and going on the "Get the Million" game show. Many of his Duel Monsters cards contain a gambling theme, and on occasion, his strong luck helps him win in the end.
Jonouchi's skill at Duel Monsters is somewhat near as good as that of Yugi's, but he still duels as part of a tag team on occasions and he strives to improve his skill. This is a frequent subplot throughout the series, although it was muted somewhat in the English anime, and also he uses many warrior type monsters.
Jonouchi (Joey) in the second series anime
Jonouchi has a sister named Shizuka Kawai (Serenity Wheeler in the English anime; Shizuka Jonouchi in the first series Yu-Gi-Oh! anime). In the Japanese versions of Yu-Gi-Oh!, Shizuka's surname is her mother's maiden name while Jonouchi's is his father's surname. Their parents divorced when Jonouchi was 10. Shizuka was brought away by her mother while Jonouchi lived with his father. In the manga and the Duel Monsters anime, Shizuka started to go blind, so Jonouchi entered the Duelist Kingdom tournament to finance her eye surgery. Jonouchi would come second to Yugi in the event, although Yugi gives him the money to finance the surgery. In the first series anime, Shizuka is chronically ill and in the hospital. Therefore Jonouchi ensures that she gets the best care in the hospital.
Jonouchi never appears in Yu-Gi-Oh! GX, although he has been mentioned: in the first season he is seen in flashbacks to Battle City, and early in the third season Maximillion Pegasus says to Aster Phoenix that Jonouchi is the third best duelist in the world, the first being Yugi Mutou and the second being Seto Kaiba.
In episode 179, he is seen in a poster with Yugi, Anzu, and Honda.
Throughout the majority of the series, Jonouchi's deck is mainly composed of Warrior-type monsters. At first it is composed solely of monsters, but after he trains with Sugoroku Mutou, he adds more cards to it. His signature monsters are associated with fire, such as Red-Eyes Black Dragon, and Flame Swordsman. During Battle City his Time Wizard becomes central to his deck that evolves to become slightly more luck based with cards like Skull Dice (a Trap Card that takes away an opponent's monster's ATK points) and Graceful Dice (A Spell Card that increases one of Joey's monster's ATK points). Such cards help in balancing his lack of access to stronger cards, quite possibly owing to not having much spending money due to his debt-paying commitments as well as being a relative newcomer to Duel Monsters. After Battle City, Jonouchi maintains his Warrior strategy, powering them up with a variety of Spell and Trap cards, which can be quite useful when Kaiba uses his Crush Card against him. His Jinzo becomes another of his signature cards, as does Scapegoat (a Spell card that protects Joey's Life Points from direct attack) and Kunai with Chain. Other notable cards in his deck include Gearfried the Iron Knight, Legendary Fisherman, and Insect Queen. In addition, his Jinzo has a special ability that automatically destroys every Trap Card on the field.
