Jack Atlas appears as a major protagonist and as a rival to Yusei Fudo in Yu-Gi-Oh! 5Ds. His voice is highly reminiscent to that of Barney Gumble from "The Simpsons". Upon meeting Yusei in a video declaring there will be a new abridged series, he received the message "Card games on motorcycles!" from him, prompting him to repeat the phrase to every major and minor protagonist and antagonist throughout the Yu-Gi-Oh! franchise, but not limited to them. In the conclusion of the rap battle between Yami Yugi and Jaden Yuki, Jack made a cameo appearance after Yusei accidentally ran over Jaden with his Duel Runner, exclaiming the phrase "On motorcycles!" after Yusei explained his reason for arriving on the scene was "to play a card game".
As seen in the Yu-Gi-Oh 5Ds One Shot Parody Special, Jack believes that he has a great singing voice, but in reality, his singing is terrible. In the aforementioned special, Jack's singing voice is the cause of several explosions, including the Zero Reverse. Strangely, his voice also causes explosions even when Jack himself isn't physically present; when Jack did a mic check on Yusei's TV, the TV exploded, with Yusei saying that his friends owed him a new TV.
Jack is shown to be rather dumb, gullible and somewhat childish. He always yells simple words when talking, and spawned the meme "CARD GAMES ON MOTORCYCLES!" This allows Leichter to blow him up with his anti-meme powers in episode 52.
In "Yu-Gi-Oh! Bonds Beyond Time Abridged" he states that the movie Top Gun isn't gay. When first seeing Paradox, he says his hair is beautiful. When Yusei finds Paradox in a picture, he thinks it's Waldo who stole Yusei's Stardust Dragon. And then when reality is disintegrating, Jack thinks it snowing and there's no school today. When Yusei travels back in time, Jack shouts after him, "DON'T EAT THE YELLOW SNOW, IT'S PEE!!!"
