They often form alliances with individuals that can give them more power , as they go from working for Gozaburo Kaiba , to Seto Kaiba , to Maximillion Pegasus , and finally , to Noah Kaiba . History . KaibaCorp . At some point they were hired by Gozaburo Kaiba to work for KaibaCorp , a military arms company . When Gozaburo ' s stepson Seto decides to make his play for power , he convinces the Big Five he ' ll restore them to their former power and claims that Gozaburo does not give them the respect or power they deserve . The Big Five agree , and thus buy 49 % of KaibaCorp . Combined with 2 % that Gozaburo had previously given to Seto for a test to prove his business skill , the Big Five vote out Gozaburo and vote in Seto as the president of the company . However , Seto quickly backs out on their deal , stripping them of their power and leaving the Big Five little more than figureheads and consultants . KaibaCorp would soon be converted into a video game software company where he had Nezbitt destroy his weapon labs and rejected Crump ' s idea for a penguin theme park as part of a KaibaCorp project . Duelist Kingdom . Furious over their betrayal , the Big Five strike a deal with Maximillion Pegasus , similar to their previous deal with Seto : if Pegasus defeats Seto and Yugi Muto in Duels , then they will vote Pegasus into power of the company by kidnapping Seto ' s brother Mokuba , who has been entrusted with the card that contains the information the Big Five need to take over the company ( In the dub , they need a Kaiba family member to make any control legal ) Although shadowed during this time , the Big Five are first unshadowed when they watch Maximillion Pegasus ' Duel against Yugi Muto on their monitor . However , the plan fails when Yugi defeats Pegasus in a Duel . In the manga , the Big Five are fired by Seto and never seen again . Legendary Heroes ( anime only ) . In the anime , when Seto learns of their betrayal he threatens to fire them . The Big Five offer Seto the opportunity to test his complete Virtual Reality game as a peace offering . In reality , they plan to trap Seto in the game so they can take control of KaibaCorp . When Yugi Muto and Joey Wheeler enter the Virtual World with Mokuba to rescue Seto , the Big Five send Kemo and two other operatives to unplug their pods , which would trap them all . While Téa Gardner and Tristan Taylor stall the thugs , the Big Five enter the game and Summon " Mythic Dragon " . The dragon is defeated and the heroes return to the real world . After their defeat , the Big Five somehow become trapped in virtual reality . Virtual World ( anime only ) . For some time , the Big Five wander KaibaCorp ' s computer banks until they are found by Gozaburo ' s biological son Noah . Noah also desires to take control of Kaiba Corporation from Seto , and strikes a deal with them . Noah lures Seto Kaiba , Yugi , and his friends to an underground military base , and there forces them to enter his version of the Virtual World . The Big Five greet them and reveal the deal they have made with Noah : after being trapped in the Virtual World , they have lost their connection to their real - world bodies and thus need new ones . In exchange for being allowed access to the bodies of Seto , Yugi , and his friends , the Big Five will defeat each of them in a Duel . Taking the physical appearance of their respective Deck Masters in their Duels , one by one the Big Five fail to defeat their chosen opponents , each underestimating the gangs ' natural feel for the game as opposed to the Big Five ' s more calculated business - like strategies ( although the inexperienced Téa needed some help from Yugi to win her Duel against Crump ) . However , Nezbitt was able to defeat Tristan in a three - one - one Duel ( which also included Duke Devlin and Serenity Wheeler ) when Tristan sacrificed his remaining life - points to save the struggling Serenity . Although Nezbitt still lost the Duel overall , he took over Tristan ' s body despite his promise to return it . In Tristan ' s body , Nezbitt kidnaps Mokuba and hands him over to Noah and shortly afterwards the remaining Big Five attempt to steal the remaining gangs ' bodies by force . Although Noah is furious at their losses and rule - breaking in their attempted body stealing , he offers the Big Five a last ditch effort to all use the body of Tristan and Duel Yugi and Joey in a two - on - one match . With the Big Five initially rotating control of Tristan ' s body while communicating with each other in his mind , they were able to combine their Deck Masters into one monster , but they once again failed to defeat them and are summoned back to Noah ' s headquarters after trying to take the gang ' s bodies by force a second time , which infuriates Noah . Despite their pleas , Noah refuses to give them a third chance . In the original Japanese version , Noah deletes the Big Five . In the dub , he imprisons each of the Big Five in an isolated portion of the Virtual World , and they are eventually " deleted " when the Virtual World destructs . Deck . When they faced Yugi and Joey , the Big Five Dueled as one in the body of Tristan Taylor , rotating their Deck Master s in turn , as well as which member of The Big Five had control . In this Duel they use a Deck of their combined powers , highlighted by " Mythic Dragon " , the monster they attempted to use to trap Seto in the Virtual World before he fired them . They were nevertheless defeated when Yugi and Joey combined their Deck Masters ( " Dark Magician " and " Flame Swordsman " ) to form " Dark Flare Knight " , subsequently using its effect to Summon " Mirage Knight " to destroy " Mythic Dragon " , before destroying their " Berserk Dragon " by transforming " Dark Magician " into " Dark Magician Knight " and transferring most of the ATK of " Flame Swordsman " to him , thus giving him the strength to defeat " Berserk Dragon " .
