Jack Atlas is a friend of Yusei Fudo as well as his rival. Jack Atlas debuts in Season 20 of Super Smash Bros. Crossover as the second best Turbo Duelist at the Duel Dome of Smash City, falling behind Yusei. After dueling Yusei and losing (although he did reduce Yusei's life points to 100), Yusei introduces Jack to Naruto Uzumaki, Pikachu, and Pichu. Jack states its an honor to meet one of the Heroes of Legend, referring to Naruto, and gives Pichu and Pikachu his autograph and tells them they make a pretty good team.
Jack's appearance is based off his main appearance in Yu-Gi-Oh! 5Ds.
Jack enjoys Turbo Duels, as his Duel record states he rarely duels normally. Jack also respects the Heroes of Legend, which is shown when he first meets Naruto. If Jack happens to ignore someone, he will immediately do something to make up for it, as he gave Pikachu and Pichu his autograph to apologize for ignoring them.
