Gozaburo Kaiba Gozaburo Kaiba was Seto and Mokuba Kaiba ' s adoptive father and the former CEO of KaibaCorp . He was the final antagonist in the Virtual World arc , after his biological son , Noah Kaiba failed and was defeated by Yami Yugi . Biography . History . Gozaburo was the original founder and CEO of KaibaCorp , which , at that time , was a successful arms manufacturer . Because of the nature of his business , Gozaburo became involved in a war where he financed tanks and weapons to one faction , who easily overcame their enemies . Dartz , disguised as Gozaburo , lent weapons from KaibaCorp to the opposing faction as well , and made many people believe that he was only interested in making money through war . At one point in his life , Gozaburo had a son , Noah , of whom he intended to raise as the KaibaCorp heir . Gozaburo looked for the best teachers and education for his son . Gozaburo also spent time with Noah , and took him out to the sea at one point . Gozaburo became a famous chess champion , who won the World Championship and donated the prize of $ 100 , 000 to the orphanage where Seto and Mokuba lived . The brothers heard of him on TV , so Seto developed a plan to be adopted , studied everything that he could about chess and Gozaburo , and learned his way of thinking and strategies . When Gozaburo visited the orphanage , he gave toys to the kids , and on his way out , Seto challenged him to a game of chess , and told Gozaburo that if he refused , he would tell the press that he was scared of a little kid . Confident that he would not be beaten by a child , Gozaburo agreed to a single game with Seto , and stated the stipulation that if he won , Gozaburo would agree to adopt him along with his brother . Seto had spent time studying Gozaburo ' s strategies and how to overcome them , and thus defeated him . Gozaburo had to keep his end of the bargain . After he was defeated by Seto , Gozaburo met with Noah . He showed his son a picture of Seto , told him he would be his adoptive brother , that both would compete to inherit KaibaCorp and would become rivals . After that talk , Noah was crushed by a car . Noah was transported to the Kaiba Hospital , but the doctors couldn ' t do anything to save him . Gozaburo wanted to save his son at any cost . After he found a way to do it through technology , Gozaburo digitized Noah ' s mind and transferred it into a KaibaCorp computer . Noah was then given a funeral . A woman , possibly Gozaburo ' s wife , wondered how could the events have happened . Gozaburo told her not to worry since there was nothing that he could not do . Noah awoke in the Virtual World and saw Gozaburo on a screen , where he explained what happened . Gozaburo slowly expanded the Virtual World , and even programmed a space trip for his son . At first , Noah thought that Gozaburo would bring Seto to compete against him , which meant that if Noah won , the Virtual World would overcome reality and he could rule KaibaCorp . Gozaburo ' s true intentions were actually to use Seto ' s body as Noah ' s recipient , while making his adopted son think that he was being bred as his heir . However , Gozaburo soon understood that Noah could not inherit KaibaCorp because of his lack of contact with society , and because the virtual could not rule humans . Because of that , Gozaburo ' s visits to Noah became less frequent and he wasn ' t amused by his deeds . On Noah ' s birthday , Gozaburo was told by his son that with KaibaCorp ' s military weapons , 97 % of the human population could be destroyed in 30 days . After he heard that , Gozaburo started to develop a plan to leave only the Virtual World , so he began the construction of a missile satellite to destroy the major cities across the world . That day , Seto and Mokuba arrived at the Kaiba Mansion . Gozaburo was a cruel father to Seto , who forced him to spend all his time studying and forgoing any of the joy or fun that was usually associated with childhood . He put the condition that if Seto didn ' t study as intended , he would be returned to the orphanage , and drove his adopted son to strict educational regiment for the gifted . One day , Gozaburo asked Seto what would he do if he inherited the company , and was disappointed when Seto answered that he would create Kaiba Land . Gozaburo confiscated all the games that Seto owned because of that , and made every day like constant torture . But Gozaburo didn ' t realize that he was turning his successor into his greatest enemy . Gozaburo threw a party in which he invited Mr . Schroeder to discuss a deal . They were accompanied by Seto , Mokuba , and Zigfried von Schroeder . Mr . Schroeder first praised Gozaburo because of his fine successor and added that his son was also a genius . The lights from the party started to flicker on and off , and Kemo informed Gozaburo about a computer virus . Gozaburo was astonished as their computers were well protected and he couldn ' t imagine who could have done that . Four years later , Seto developed a virtual simulation system that was to be used in games , but Gozaburo planned to use it for warfare . One day , Seto insisted to Gozaburo that it had to be used in games , and made him angry . He told his adopted son that the objective of the Kaiba Family was the world domination with military weapons , and Kemo and other guard took Seto out of the office . After that , Seto stopped calling Gozaburo " father " . One year later , Seto concluded his studies . Gozaburo made the fatal mistake when he gave Seto 2 % of KaibaCorp shares as his birthday present . He put Seto on a mission to earn 100 times ( 10 times in the English Version ) that amount through investments within a year in order to test if he was capable of inheriting KaibaCorp , or else he would return to the orphanage . Seto overcame the expectations of Gozaburo by easily accomplishing his mission . However , Seto set in motion his own plan , he , along with the KaibaCorp Board of Directors ( later known as The Big Five ) , started buying shares of KaibaCorp until they reached 49 % of the company . Gozaburo , also with 49 % , realized Seto ' s plan . Because of that , Seto hurt Mokuba to force him to spend more time with Gozaburo than with him . This was actually a ruse to deceive Gozaburo into thinking that Mokuba would support him instead of his brother . He was proven wrong when Mokuba , remaining loyal to his brother , transferred his 2 % of the company to Seto . First Series Anime . In Episode 20 , Gozaburo returned . He questioned Seto on why he created Kaiba Land and finished it even though it was over budget . After he angrily denounced Seto for the way that he ran the company , Seto announced that he was in control and the board members went to his side , which showed Gozaburo that he was in control . Gozaburo looked at the street below the board office , and then collapsed in shock . Death . Gozaburo , Seto , the Big Five , and other high ranking employees attended a meeting . There , Gozaburo , confident that he owned 51 % of the company , revealed his plan to defeat Seto which consisted in transferring his shares to a subsidiary , but was ousted from power when Mokuba decided to betray him and give his 2 % of the company to his brother . That weakened Gozaburo ' s mind and lead to him committing suicide ( in the dub , he ran away and disappeared forever ) . Virtual World . It was revealed that , while Gozaburo ' s body died , he had previously digitized his mind like he did Noah ' s , and hid inside the KaibaCorp computer banks . Because of Seto ' s treachery , his plans were shattered , so he changed them . Instead of using Seto ' s body as the recipient of Noah , it would become the recipient of KaibaCorp . Although Seto would rule it for a time , Gozaburo had planned on taking his body later on . When Noah lured Seto and others , including Yugi Muto , into the Virtual World , Noah had the Big Five try and defeat Yugi , Seto , and company . When they failed one by one , Gozaburo revealed himself as the mastermind of the capture to everyone and Noah . He was disappointed by Noah ' s defeat as he could not take Seto ' s body , but had managed to hack into KaibaCorp ' s network . Through it , he accessed his secret missile satellite . No longer needing Seto ' s body , he unveiled the final stage of his plan : Launching missiles against the human leaders , hack into every computer system in the world , and rule humanity through the Virtual World ( in the English version , he wanted to digitize the entire world and reign as King of the Virtual World ) . Gozaburo then closed all the exits that he knew of the Virtual World . Noah then pretended to lead the group to a secret exit , but instead split them up , and left most of them wandering a Virtual Domino City while Noah , after he realized that his father was only using him , used Mokuba ' s body to escape , changed the trajectory of the missiles to the fortress , and intended to destroy everyone inside while he escaped . While Yugi and the others tried to escape , Seto went to confront his adoptive father . Gozaburo , who was still bitter over his loss to Seto in chess years ago and because Seto " stole " KaibaCorp , challenged him to a duel to give him the same type defeat that he delivered to him . As a further insult , Gozaburo used the monster " Exodia Necross " ( a ghostly dark version of " Exodia the Forbidden One " , the monster who handed Seto his first Duel Monsters defeat ) . Exodia Necross gained 1000 ATK during every one of his Standby Phases , could not be destroyed by Spells , Traps , and Monster Effects , and could be destroyed in battle . However , its special abilities depended on having all 5 Exodia parts in the Graveyard . During the Duel , Gozaburo and Seto were informed that the fortress would be hit by a missile and the Virtual World would be destroyed . Gozaburo was astonished because of the betrayal of his own son and for his plans getting ruined again . After he knew that he would die , Gozaburo tried to take Seto ' s body , but Seto stopped him by offering that the winner of the duel would escape to the real world . Seto used " Soul Demolition " to Remove the Exodia parts from play , and neutralized " Exodia Necross " . Now stripped of its powers , " Exodia Necross " was destroyed by Seto ' s " Blue - Eyes White Dragon " . Gozaburo lost the Duel and his chance to escape the Virtual World . With the fortress about to be destroyed , Gozaburo attempted to take Kaiba ' s body by force by transforming into a red creature . Yugi entered and helped Kaiba escape to the real world . Noah , having had a change of heart , appeared on Gozaburo ' s back , immobilized him as well as prevented him from downloading himself to another network . As Seto and Yugi emerged on the airship and escaped , the fortress exploded , and deleted Noah . Gozaburo lived for a few moments , somehow became ' real ' as a beast of flame , and erupted from the ruins of the fortress . As Gozaburo attempted to destroy the airship , Seto activated the airship ' s thrusters , jetted out of his grasp for good , and left him to sink into the waves . Legacy . Although that was Gozaburo ' s first and final appearance in person , he appeared in flashbacks before and after the Virtual World . Kaiba ' s goal to defeat Yugi Muto at Alcatraz ( Battle City ) was not only a mission to defeat Yugi , but to overcome Gozaburo ' s legacy and put it behind him . Kaiba felt that only when he was crowned Duel King atop the Duel Tower , amidst the rubble of the military factories that Gozaburo had built there , that only then could he forget his past and step out of Gozaburo ' s shadow . Alister of Dartz ' s group , Doma , also harbored a grudge toward Seto , and believed that Gozaburo had funded a military attack on his town , although he later realized that the attack was instead ordered by Dartz who was disguised as Gozaburo , and thus ended his rage against Seto . Personality . Gozaburo was a strict and persistent man . He was considered evil by many because he constantly manipulated people , including his own son , to achieve his goals . At first , Gozaburo appeared to be a caring father , training his son to succeed him as CEO of KaibaCorp . He never really cared for Noah , and rather just saw him as a tool for KaibaCorp to take over the world with . His plan was to make Noah ' s mindset identical to his to accomplish his goal . After Noah ' s accident , he only wanted to save him at any cost , but by doing so , he discovered a plan to destroy the real world and rule the virtual world instead . However , Gozaburo saw Noah ' s death as having a wrench thrown into his plans and did not really care about him . Originally , Gozaburo planned to have Seto become a host to replace Noah ' s dead body because of the limitations of the virtual world . In the English dub , Seto proved himself more capable than Noah , so he ultimately scrapped the plan . In the original , that never occurred because Noah ' s lack of interactions with real people inhibited his maturity . Upon hearing that , Yami Yugi , despite his difference with Seto , understood why he hated Gozaburo so much . He usually didn ' t recognize the hard work of the Big Five . He was very strict with Seto , though he was nicer ( or at least not as openly cruel ) to Mokuba . Meanwhile , Gozaburo used Noah to set his ambition into motion . Design . Appearance . Gozaburo ' s appearance was that of a tall man , with gray hair and a mustache . In the manga , his facial expressions showed evil and madness when he committed suicide , while in the anime , he seemed like a calm and deceitful man . He usually wore a red business suit , a black tie , and a white inner long - sleeved dress shirt . Gozaburo had brown eyes and was fair skinned . Decks . Anime . Gozaburo played an Exodia Necross Deck . His strategy revolved around Summon ing " Exodia Necross " by quickly sending the pieces of " Exodia " to the Graveyard through " Painful Choice " . He then relied entirely on the immunity and ATK raising abilities of " Exodia Necross " , which provided decent offense and defense , but whose weaknesses proved to be his undoing . Before his Duel with Seto , Gozaburo Summon ed a number of monsters with a chess theme against Yugi and company , using their respective chess pieces - " Cosmo Queen " ( Queen ) , " Skull Knight " ( Bishop ) , " Command Knight " ( Knight ) , " Rock Ogre Grotto 1 " ( Rook ) , and " Lizard Soldier " ( Pawn ) .
