Paradox 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 Duel ing Yugi Muto , Jaden Yuki and Yusei Fudo . 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 . According to it , a paradox is created if the past is altered which then changes the future entirely . This references his mission of changing history by destroying the game of " Duel Monsters " to prevent his own terrible future from happening , which would have caused catastrophic and drastic changes to the future had he succeeded He is the only one of Z - one ' s comrades to not guard a Planetary Particle as he was defeated before then . Sherry LeBlanc replaces him as the third guard of a Planetary Particle . Biography . Yu - Gi - Oh ! 5D ' s . Paradox was one of the survivors of the " Meklord Emperor " genocide along with Z - one and Antinomy , who eventually discover a fourth survivor , Aporia . Together , the four of them had conducted many experiments in order to prevent the genocide , succeeding in granting Z - one eternal life thanks to a life support system they created . However , Paradox alongside Antinomy and Aporia eventually died from natural causes and were placed in capsules , leaving Z - one the only survivor . Yu - Gi - Oh ! 3D : Bonds Beyond Time . A robotic copy of Paradox ' s younger self was created by Z - one , and programmed with his original self ' s hatred of " Duel Monsters " for bringing about the end of the world . Paradox was charged with killing the game ' s creator , Maximillion Pegasus , and given a Duel Runner capable of traveling into the past to assassinate him . If Pegasus was killed before recreating the Shadow Games as " Duel Monsters " , this would effectively rewrite the future ; thus the Meklord Emperor Genocide that destroyed Paradox ' s world would never have occurred However , Paradox decided to go about this in a different manner ; rather than simply kill Pegasus , he decided to kill him a large public " Duel Monsters " event , to scare the populace into thinking the game was the cause and make it ' s popularity drop . If successful , this would cause a domino effect on the timeline , wiping " Duel Monsters " ' influence from history . Paradox was aware there may be negative consequences , but believed it was necessary as many great evils that threatened the world by using " Duel Monsters " . Paradox traveled to the New Domino City , during Yusei Fudo ' s time . He interrupted a Turbo Duel between Yusei , Crow Hogan and Jack Atlas . Yusei has just Summoned " Stardust Dragon " , but Paradox absorbed it into a blank card . He showed Yusei the corrupt card , when confronted , before vanishing through time again . He traveled further back in time to Venice , during Jaden Yuki ' s time . Causing massive destruction , Paradox attacked Jaden with " Cyber End Dragon " and " Rainbow Dragon " . Elemental Hero Neos protected Jaden , so Paradox Summoned " Stardust Dragon " to fight off " Neos " . However , Yusei who has traveled back in time with help from the Crimson Dragon arrived and saved Jaden . Though unsure of how Yusei followed him back into the past , Paradox decides to let the alterations to the timeline finish him and Jaden off . Paradox proceeded to visit an event where Pegasus was giving cards to young children , in Yugi Muto ' s time , where he used " Cyber End Dragon , " " Rainbow Dragon " and " Stardust Dragon " to attack the area . Obsessed with the utter destruction of the " plague " that destroyed his home time , Paradox cared little for the other people in the area , killing them along with Pegasus and Solomon Muto with a falling building . Paradox witnessed the aftermath of his attack and claimed that with this the world had been saved . Yusei and Jaden arrived in this time and recruited Yugi , who was the lone survivor of Paradox ' s attack , to fight Paradox . Yusei , Jaden and Yugi traveled back in time to exactly thirty minutes before Pegasus ' event , scaring off the patrons to keep them alive . Paradox ( from before his attack in the alternate timeline ) arrived to stop them from interfering . He explained what his goals are and how despite their efforts , Yugi , Jaden , Yusei would be unable to prevent the world ' s eventual destruction . Enraged , the three challenged Paradox to a 3 - on - 1 Duel . Paradox accepted and transformed his Duel Runner into a hovercraft . Paradox used " Malefic World " and his corrupt " Malefic " counterparts of existing monsters . Yusei , Jaden and Yugi managed to retrieve " Stardust Dragon " from him , but Paradox retaliated with " Malefic Truth Dragon " and pushed them into a corner . As he was about to win , Paradox taunted Yusei . However , with Jaden and Yugi ' s help , Paradox ' s final attack failed and the three overpowered " Malefic Truth Dragon " and won the Duel , which destroyed Paradox in the process . Right before dying , Paradox wondered if his experiment was wrong . Z - one later mentioned Paradox when explaining his plans to Team 5D ' s , and Yusei recognizes his name and remembers his encounter with him . Z - one revealed that it was him who had sent Paradox to the past . Before he died , Z - one said that by remembering Paradox , Antinomy and Aporia ' s bond he was able to find the strength to fight by himself , and that he considered the three to be his family . Abilities . Paradox possesses a Duel Runner that bears similarities to the one used by Aporia . The Duel Runner is shown to travel through time and change between modes . Like Yusei ' s Duel Runner , Paradox possesses a hybrid model . < tabber > < / tabber > Although not explicit in the movie , Paradox is an android much like Aporia and Antinomy . He is capable of creating corrupted versions of the signature card s of other " Yu - Gi - Oh ! " characters in the franchise . Paradox is capable of merging with his ace monster , " Malefic Truth Dragon " . Paradox has also demonstrated the ability to steal Duel Monsters right out of their cards ( such as with " Stardust Dragon " during his Turbo Duel with Yusei ) using a blank card , and the ability to bring them to life ( he demonstrated this ability with " Cyber End Dragon " , " Rainbow Dragon " and " Stardust Dragon " during his attack on Venice , and his attack on the Domino Duel Tournament ) . Deck . Paradox plays a " Malefic " Deck , made of up of an archetype of DARK - Attribute Dragon - Type monsters ( with the exception of " Malefic Cyber End Dragon " and " Malefic Parallel Gear " , both of which are Machine - Type ) which are corrupt versions of the trump cards of other " Yu - Gi - Oh ! " characters , which he traveled through time to steal . Paradox ' s preferred Field Spell is " Malefic World " , which gives him the option of skipping his Draw Phase each turn , and instead adding a " Malefic " monster to his hand from his Deck . His monsters are supported by several Spell and Trap Card s that include the word " Malefic " in their names .
