Joey Wheeler or A.K.A. Katsuya Jonouchi in the manga and Japanese version of the Yu-Gi-Oh! anime is a friend to Yugi, Tristan and Tea.
Joey was originally a bully who picked on Yugi with Tristan Taylor but soon they became his best friends. Joey is an enthusiastic duelist who learned Duel Monsters from Yugi and his grandpa. He cares deeply for his sister Serenity and his reason for dueling is to help the people you love.
Joey is often used for comic relief but is still an essential character. Over the course of the series Joey becomes a better person and a more experienced duelist. He is often mocked for being an amateur despite his accomplishments, and he has the unfortunate luck of dueling people who try to cheat. Joey's favorite Duel Monsters card is Red-Eyes Black Dragon.
In the English dub version of the anime by 4Kids Entertainment, Joey Wheeler was voiced by Wayne Grayson.
In a lesser known English dub by Odex Ltd Joey Wheeler was voiced by Dwayne Tan.
