Paradox is the main antagonist in Yu-Gi-Oh! The Movie: Super Fusion! Bonds That Transcend Time.
A formidable enemy who travels through time and space to change his destroyed future by fighting Yugi Muto, Jaden Yuki and Yusei Fudo. He wears a mask and his true identity is draped in mystery. In the movie he will steal Yusei's Stardust Dragon and will use it against him. He apparently can steal cards in a duel by using a giant string of unrevealed cards when the card is activated or on the field, and he automatically corrupts them into a Sin monster when he does so. He plans to eliminate the creator of Duel Monsters, Pegasus, and destroy the three historic duelists, attempting to save the future from ruin. He interrupts a Turbo Duel between Crow, Jack Atlas, and Yusei Fudo, in order to steal the third dragon.
