Bandit Keith is the former U.S. Duel Monsters Champion. In the manga, he was first referenced by Seto Kaiba as a Card Professor, one of many famous Duelists who were known for winning the prizes in large Dueling tournaments. He was so successful in this profession, that his reputation earned him the nickname "Bandit Keith". In the English manga, many of his dialogues have been modified to contain many censored profanity, to indicate his lack of respect for others.
