Paradox, Yu-Gi-Oh! Wiki

Paradox is the main antagonist in Yu-Gi-Oh! 3D Bonds Beyond Time who is able to travel through time and space to change his destroyed future by killing Maximillion Pegasus to prevent Duel Monsters from being created. He was one of mankind's last four survivors in an apocalyptic future, along with Z-one, Aporia and Antinomy. Unlike his fellow survivors, not much of his backstory prior to meeting the other survivors is shown. His name is derived from the concept of "paradox" in the theory of time.
