During a Turbo Duel with Jack Atlas and Crow Hogan, Yusei Fudo’s Stardust Dragon is captured by Paradox, a mysterious Turbo Duelist from the future, and transformed into a Sin Monster. With the help of the Crimson Dragon, Yusei pursues Paradox as the duel triggers a time slip, sending them back to the past. In that era, Paradox duels Jaden Yuki, who still wields the powers of Yubel and the Supreme King. Paradox has also captured Cyber End Dragon and Rainbow Dragon, giving him overwhelming advantage. Yusei and the Crimson Dragon rescue Jaden, and he reveals Paradox’s true plan: to steal monsters from different timelines, darken them, and ultimately defeat Maximillion Pegasus.
