Besides his physical differences , the fake Jack also features subtle alterations to his voice in each adaptation . In the Japanese version , the Fake ' s voice has a robotic echo added . The dub has Fake Jack ' s voice slightly more high - pitched than the original , making him appear to snarl in almost of all of his sentences . Personality . Fake Jack behaves much like Jack was before becoming friends with Yusei again , such as being obsessed as the King of Duelists and claiming the " King ' s Dueling must be for entertainment " . He also performs the same Synchro chant as Jack for " Red Dragon Archfiend " . Biography . Pre - World Racing Grand Prix . Jack was arrested by Sector Security , suspected for a streak of destruction in New Domino , running Duel Runner s off the road and injuring their riders . It is later revealed that it was the work of an impostor and Jack rushes to find them . When he locates the impostor , " Enemy " Jack tries to run him off the road , before challenging him to a Turbo Duel . As the Duel is about to commence , an Infinity symbol appears , with Jack wondering what is causing the light surrounding them . During the Duel , the impostor constantly taunted Jack , by repetitively referring to himself as " King " , much to Jack ' s shock and disgust . When Jack draws " Trust Guardian " , he chooses to use " Dread Dragon " instead because he believed " Trust Guardian " won ' t fit his style of Dueling . This however allows the impostor to defeat Jack easily and run Jack off the highway and into the sea , using the real damage caused by " Red Dragon Archfiend " . Yusei and Crow arrive on the scene and the impostor distracts them with " Red Dragon Archfiend " to escape . Yusei and Crow believe Jack has gone mad . The impostor was later pursued by Kaz , Yusei and Crow and rammed their Duel Runners while taunting at them just before the real Jack Atlas reappears for a rematch . This time , Jack decides to use " Trust Guardian " for this Duel , knowing that his pride was what caused him to lose in their previous Duel . This allows the real Jack to turn the beginning of the Duel in his favor , as he is able to not only destroy the robot ' s copy of " Red Dragon Archfiend " , but also inflict major damage to its Life Points . However , the impostor makes a comeback in trying to winning the Duel by Summon ing two more copies of " Red Dragon Archfiend " and reviving the copy that Jack destroyed . Both copies , along with the third one he had Special Summon ed from the Graveyard , are able to decrease Jack ' s Life Points dramatically . The impostor tells Jack that he won ' t be able to win , given that he isn ' t the same person as he was before . However , Jack disproves this with the power of his friends and the Crimson Dragon . He Summon s " Majestic Red Dragon " and uses it to win the Duel . At the end , the overwhelming attack destroys the robot and its Deck completely ( in the dub only his helmet , Deck and Duel Runner are shown being destroyed and the robot is seemingly vaporized by the explosion ) . Despite the robot ' s destruction and the loss of the copied cards , the Nobles don ' t consider it a total loss as Jack ' s power gives them another piece of the Circuit . World Racing Grand Prix . He was later seen in a flashback after Team 5D ' s defeated Team Unicorn and had a party where the group remembered the times that they Dueled strange opponents who inflicted real damage . Deck . Fake Jack uses a Jack Atlas Deck , primarily focused on Synchro Summon ing 3 " Red Dragon Archfiend s " , of which all were different colors than the original ; purple , yellow , and green . He also utilizes a large amount of Trap Card s to support it such as " Lineage of Destruction " and " Crimson Fire " . This Deck was constructed by Lester as " Red Dragon Archfiend " is a unique card , therefore no other authentic copies of it existed .
