Dark Yugi and Seto Kaiba ' s Battle City Duel ( manga ) Dark Yugi and Seto Kaiba faced each other in a game of " Duel Monsters " in the second Battle City semifinal , in the " Yu - Gi - Oh ! " manga . Events . Prior . After Death - T , Yugi had hoped to face Kaiba in a fair Duel . At the conclusion of the Duelist Kingdom tournament , Kaiba shared a similar sentiment , declaring his battle with Dark Yugi to be unfinished until he defeated Dark Yugi in a fair Duel . With Dark Yugi as the only Duelist that Kaiba recognized as a rival , Dueling him became one of Kaiba ' s goals in the Battle City tournament . Having seen the Tablet of Memory depicting himself battling Priest Seto , Dark Yugi wondered if the tablet had predicted his present - day conflict with Kaiba and believed they were fated to battle . Yugi entered Battle City , hoping it would give him the chance for the fair Duel with Kaiba . After translating the effects of Dark Marik ' s God card , " The Sun Dragon Ra " , Kaiba calculated the odds of his Deck defeating it as being 13 % . Among the factors to improve his chances , he figured he would need to win " Slifer the Sky Dragon " from Dark Yugi and see " Ra " used in battle again . For these reasons , he decided he would need to face Dark Yugi in one semifinal and have Katsuya Jonouchi face Dark Marik in the other . His actions in the pairing - organizing battle royal , contributed to achieving these match - ups . Kaiba regarded his semifinal with Yugi to be a Duel to determine the ultimate Duelist . As such he prepared a befitting setting , the " Sky Duel Coliseum " , a Solid Vision virtual reality stage . Following Jonouchi and Dark Marik ' s Duel , Jonouchi was left unconscious and not breathing . He was considered dead by Dark Marik . With one hour until the next semifinal , Kaiba instructed Dark Yugi to overcome his friend ' s death and return in time for their Duel . Dark Yugi began to lose the will to continue fighting , until the Millennium Tauk showed him a vision of him and Jonouchi Dueling in the future . Dark Yugi returned to the top of the Duel Tower to face Kaiba . Kaiba had been worried that Dark Yugi ' s anguish would make the Duel a walkover , but was soon relieved to see that he still had his fighting spirit . Duel . Kaiba announced that the site was too drab and unworthy of their Duel . He got the pillars at the top of the Duel Tower to fold back and activate their Solid Vision projectors , setting up the Sky Duel Coliseum . He declared that they would fight their decisive battle like Roman gladiators and prompted Dark Yugi to draw his sword from his Deck . Turn 1 : Dark Yugi As he drew , Dark Yugi viewed his right hand as holding his sword , his card , his pride and his left hand as holding his shield , his Deck , his soul . Dark Yugi Summoned " Queen ' s Knight " in Defense Mode and Set " Lightforce Sword " . Turn 2 : Kaiba Kaiba drew " The God of the Obelisk " and smiled , thinking that the god of victory smiled upon him . He began to focus on a way of putting three Sacrifices onto the field . Dark Yugi wondered what kind of strategy Kaiba would use . He considered that it could be the Deck - destruction strategy he used against Ishizu Ishtar in this Duel . But with Dark Yugi already accustomed to the ins and outs of that tactic , he suspected Kaiba would employ a yet unseen strategy . Kaiba made plans for an instant - kill combo . He began by Summoning " X - Head Cannon " and Setting " Enemy Controller " . He ended his turn , thinking he would finish Dark Yugi next turn . Turn 3 : Dark Yugi Dark Yugi noted how Kaiba neglected to attack , despite having the stronger monster and wondered if Kaiba was cautious of his face - down card , but considered that there may be more to it . Dark Yugi Summoned " Kuriboh " in Defense Mode . Kaiba was unimpressed and thought he would teach Dark Yugi how foolish it is to play low - Level monsters against him . Turn 4 : Kaiba Kaiba activated " Soul Exchange " , taking Dark Yugi ' s " Queen ' s Knight " and " Kuriboh " , allowing him to Sacrifice them , but also relinquishing his sacrificial privileges of his own monsters to Dark Yugi . As soon as " X - Head Cannon " went to Dark Yugi ' s side , Kaiba activated his face - down " Enemy Controller " , allowing him to control " X - Head Cannon " . By paying 1000 Life Points ( Kaiba : 4000 → 3000 Life Points ) and entering the command " ⬅ ➡ Ⓐ Ⓑ " , he was able to Sacrifice " X - Head Cannon " . With three Sacrifices ready , Kaiba was able to Summon " The God of the Obelisk " . As he announced what he was doing and put his fingers on the " Obelisk " card , Dark Yugi activated " Lightforce Sword " , taking it out of Kaiba ' s hand for 3 turns . He taunted Kaiba , telling him not to get too hasty , as the game had only just begun . Kaiba smiled and thought the same was true for the countdown to Dark Yugi ' s defeat . With the Summoning of " Obelisk " canceled , the Sacrifices remained on the field and the effect of " Soul Exchange " ended . Although Kaiba was unable to use " Obelisk " for another three turns , he was not bothered too much , since he still had a plan to Summon a God , making use of " Voice of the Heavens " . Turn 5 : Dark Yugi With two monsters on the field , Dark Yugi was one away from having enough Sacrifices for " Slifer the Sky Dragon " , but was concerned since he had not yet drawn " Slifer " . Neither of his monsters were capable of defeating " X - Head Cannon " , so he Set " Exchange " and ended his turn . Kaiba noted that if he keeps running like that , the three turns will be over in an instant . Dark Marik arrived at the stage , keen on seeing the battle between " Obelisk " and " Slifer " . He examined the situation , observing that " Obelisk " had been pinned and Dark Yugi could not attack . He wondered who would Summon their God card first and who would win , when he believed that the victor would suffer death at his hands . Regardless of who was to win , he maintained that he would be killing Dark Yugi either way . Turn 6 : Kaiba Kaiba Summoned " Y - Dragon Head " and Dark Yugi noted its similar naming syntax to " X - Head Cannon " . He wondered if they were magnet monsters with the ability to fuse . From the fear in Dark Yugi ' s eyes , Kaiba saw that he had figured it out and fused his monsters to form " XY - Dragon Cannon " . He warned Dark Yugi that with the final part , " Z " , he would achieve their ultimate fusion . Kaiba ' s fused monsters would be too strong for Dark Yugi ' s to overcome and after two turns would provide sufficient Sacrifice for " Obelisk " . Dark Yugi realized that Kaiba had planned this from the beginning and thought it was a perfect strategy for Summoning God . " XY - Dragon Cannon " attacked and destroyed " Kuriboh " . Although Dark Yugi was losing no Life Points in having his Defense Mode monsters destroyed , he worried that it would not matter , since " Obelisk " was capable of killing him in one shot with its 4000 ATK . Kaiba asked if it scared Dark Yugi , knowing that his God card would be freed in three turns and what if he were to say that he did not have to wait . He declared that the God cards always wind up in the hands of the ultimate Duelist . Dark Marik agreed , but claimed that he was said " ultimate Duelist " , rather than Kaiba . Kaiba then activated " Voice of the Heavens " , paying 1000 Life Points ( Kaiba : 3000 → 2000 Life Points ) to declare " Slifer the Sky Dragon " , allowing him to take that from Dark Yugi ' s Deck . " Slifer " was near the bottom of Dark Yugi ' s Deck , with " Dark Magician Girl " , being at the very bottom . Being that far down , Kaiba reckoned Dark Yugi would not have drawn it this Duel . He laughed and asked if Dark Yugi now understood that the God cards only obey him . However Dark Yugi smiled and replied " We ' ll see about that . " He gestured to his face - down , " Exchange " , and said that he had planned on activating it the moment that " Obelisk " went free . Dark Yugi reflected on the Duel against Jonouchi , who was brainwashed by Marik Ishtar and how " Exchange " was used then to win back Jonouchi ' s friendship . He activated " Exchange " , while thinking that he inherited a part of Jonouchi ' s Duelist spirit that day , and took back " Slifer the Sky Dragon " . Kaiba , being able to a card from Dark Yugi ' s hand , took " Life Shaver " . Although Dark Yugi had gotten his God card into his hand , Kaiba was confident he could stop him Summoning it , by using his " XY - Dragon Cannon " to destroy Dark Yugi ' s monsters before he could gather three Sacrifices . Dark Yugi worried that even with " Slifer " , the " Life Shaver " he had given Kaiba could render " Slifer " almost powerless . Turn 7 : Dark Yugi Dark Yugi Summoned " Big Shield Guardna " in Defense Mode and Set " Soul Rope " . Turn 8 : Kaiba Dark Marik thought that Dark Yugi would have no chance of winning if Kaiba manages to Summon " Obelisk " . He hoped that Dark Yugi would not disappoint him , since he would get no fun out of crushing someone who is already half - dead . Kaiba Set " Interdimensional Matter Transporter " , which Dark Yugi suspected was " Life Shaver " . He Summoned his third magnet monster , " Z - Metal Tank " . With " X " , " Y " and " Z " on the field , Kaiba fused the three to form " XYZ - Dragon Cannon " . " XYZ " attacked and destroyed " Big Shield Gardna " , which Dark Yugi had hoped for . He knew that Kaiba loved an easy target and would not be able to resist killing " Big Shield Guardna " . Since one of his monsters was just destroyed , Dark Yugi was able to activate " Soul Rope " , which he used to Summon " King ' s Knight " . Having both the king and queen on the field , he got to Summon " Jack ' s Knight " . Like Kaiba ' s magnet monsters , Dark Yugi remarked that his Deck also contained monsters to help him Summon God cards . Turn 9 : Dark Yugi Dark Yugi sacrificed " Jack " , " Queen " and " King ' s Knight " to Summon " Slifer the Sky Dragon " . Kaiba was annoyed that Dark Yugi managed to Summon a God card before him and the virtual spectators began booing . Kaiba pointed out that with three cards in Dark Yugi ' s hand , " Slifer " only had 3000 ATK . Dark Yugi replied that it was enough to top the 2800 that " XYZ - Dragon Cannon " had , allowing him to destroy it and Kaiba ' s plan to Summon " Obelisk " . Kaiba urged him to go ahead and try . Dark Yugi was made reluctant by this confidence and reconsidered that Kaiba ' s face - down card might not be " Life Shaver " . Having not been face - down for a single full turn , " Life Shaver " would not make Dark Yugi discard anything and hence have no effect on " Slifer " . Dark Marik wondered if Kaiba was bluffing and silently commended him for holding off a God card with a single face - down card . By not attacking , Dark Yugi would allow Kaiba to Summon " Obelisk " next turn , so he decided he could not back down and gambled on the chance that Kaiba ' s face - down was " Life Shaver " . " Slifer " attacked " XYZ - Dragon Cannon " , and Kaiba activated his face - down , " Interdimensional Matter Transporter " , causing " XYZ " to disappear from the attack destination , causing " Slifer " to miss , and promptly reappear . Dark Yugi Set " Pot of Greed " , which surprised Kaiba , since it lowered the number of cards in his hand , and therefore the ATK of " Slifer " ( " Slifer " : 3000 → 2000 ATK , 3000 → 2000 DEF ) . Turn 10 : Kaiba Dark Yugi mentioned that now " XYZ - Dragon Cannon " might even be strong enough to defeat " Slifer " , without Kaiba Summoning his God card . Like how Kaiba tested him last turn , he said that it was now his turn to test Kaiba ' s will . The effect of " Lightforce Sword " ended and " Obelisk " returned to Kaiba ' s hand . " XYZ - Dragon Cannon " , having a composition of three magnet monsters , could be used as three Sacrifices , so Kaiba offered it to Summon " The God of the Obelisk " . Dark Yugi could sense immense power inside of " Obelisk " and found himself shaking in fear , like he never felt before . Kaiba announced that the clash of the titans had come , that all of the God cards were to become his and he would become the King of Duelists . In the Battle Ship , parked outside the Duel Tower , Ishizu , from Rishid ' s bedside , observed that the battle of the Gods had finally begun . In the ship ' s infirmary , Honda alerted Anzu , Shizuka and Ryuji when he saw " Obelisk " and " Slifer " Summoned on top of the Duel Tower . He made a plea for Jonouchi , who was still unconscious from his Duel with Dark Marik , to wake up and cheer for Dark Yugi . Against the doctor ' s orders , he lifted Jonouchi out of the bed and brought him over to the window . The doctor then noted a slight improvement on Jonouchi ' s heart rate monitor . Since Kaiba Summoned a monster , the " Summon Lightning Shot " effect of " Slifer " was activated , reducing the ATK of " Obelisk " by 2000 ( " Obelisk " : 4000 → 2000 ATK ) . Kaiba noted that the God cards now had the same ATK , but on the next turn " Obelisk " would return to 4000 , while " Slifer " would rise to 3000 . He thought that the outcome of the Duel would depend on the next turn and Set " Life Shaver " . Turn 11 : Dark Yugi Dark Yugi drew a card , raising the number of cards in his hand to three . ( " Slifer " : 2000 → 3000 ATK , 2000 → 3000 DEF ) . The stat - reduction effect wore off of " Obelisk " ( " Obelisk " : 2000 → 4000 ATK ) . Dark Yugi was conscious about playing more cards , since it would lower the ATK of " Slifer " , so he ended his turn . Turn 12 : Kaiba " Obelisk " attacked " Slifer " , but Dark Yugi activated " Pot of Greed " , drawing two cards ( " Slifer " : 3000 → 5000 ATK , 3000 → 5000 DEF ) . Kaiba responded with " Life Shaver " , causing Dark Yugi to discard " Dark Magician " ( " Slifer " : 5000 → 4000 ATK ) , leaving the two God cards with the same ATK . As " Obelisk " and " Slifer " destroyed each other , a brilliant white light was emitted , forming a sphere , which engulfed Dark Yugi and Kaiba . The spectators in the Battle Ship saw the light and wondered if the Duel Tower was after exploding . The Millennium Rod began to glow ; a phenomenon Dark Marik equated to its behavior during Kaiba and Ishizu ' s Duel , leaving him conclude that another of Kaiba ' s memories was about to manifest . The Millennium Puzzle reacted similarly and Dark Yugi and Kaiba consciously found themselves floating min - air at the ruins of the pharaoh ' s palace , in ancient Egypt , where they witnessed some of the battle between Priest Seto and Pharaoh Atem . Seto and Atem , stood at opposite sides of an arena . Seto declared that the High Priest of Darkness had conquered Heaven and Earth with his evil power and that Atem ' s divine right and Millennium Items were worthless against the power of darkness . He professed himself an enemy to Atem , with one wish to defeat him with his own hands . The two began to battle . Using their Millennium Items , Seto and Atem erected stone slabs and Summoned The White Dragon and Dark Magician , respectively . Dark Yugi and Kaiba recognized the scene as the one depicted on the Tablet of Memory . Kaiba and Dark Yugi returned to reality , where their God cards had both been destroyed . Dark Yugi and Kaiba were both certain that had seen themselves fighting each other in that vision . Dark Yugi was confident the scene was from his memories . They accepted that the Duel was fate and that they would not need the God cards to finish it . Trying to think of a logical explanation for what happened , Kaiba thought it must have been a realistic illusion . However the presence of the king , facing the priest and the immense fighting spirit from the two convinced him otherwise . Regardless of what he had seen , he affirmed that his goal was to defeat Dark Yugi and become the King of Duelists . Kaiba Set " Clone Reproduction " and thought to himself that the only thing that can beat Dark Yugi is a card that surpasses the Gods , " Blue - Eyes White Dragon " , which he had in his hand . Turn 13 : Dark Yugi With no monsters on Kaiba ' s side of the field , Dark Yugi wondered if he could make a successful attack and Summoned " Baphomet " . Kaiba then activated " Clone Reproduction " , Summoning a copy of " Baphomet " to his side and reminded Dark Yugi that a battle would result in the destruction of both monsters . Dark Yugi switched " Baphomet " to Defense Mode and Set " Magic Formula " . Kaiba commented that it was a wise move , but that he was going to Sacrifice the clone . Turn 14 : Kaiba With the God cards in the Graveyard , Dark Yugi deduced that Kaiba ' s next play would be " Blue - Eyes White Dragon " . Since he we need an extra monster to perform the Sacrifice Summon , Dark Yugi figured he would not be able to play it this turn and wondered if he would be able to draw his own key card , " Monster Reborn " , before then . However Kaiba activated " Cost Down " , lowering the Level of " Blue - Eyes White Dragon " by two , allowing him to Summon it with a single Sacrifice , and used the clone monster to do so . He warned Dark Yugi that the ancient illusion was over and that this was reality , where Dark Yugi was to be defeated . " Blue - Eyes White Dragon " attacked and destroyed " Baphomet " . Turn 15 : Dark Yugi Dark Yugi drew " Monster Reborn " . He reminded Kaiba of the tablet depicting the battle they witnessed . Pharaoh or priest , he said it did not matter who the people were , what was carved was their spirit as Duelists and that spirit has been passed on to him and Kaiba . He then activated " Monster Reborn " to revive " Dark Magician " , which Kaiba realized must have been the card discarded for " Life Shaver " . The field now echoed the scene from the tablet . Dark Yugi noted that the tablet did not say what happened next and that it was time for them to settle it . Dark Yugi Set " Spellbinding Circle " . Turn 16 : Kaiba Kaiba rationalized that the vision was an illusion created by subliminal suggestion ; when they saw the carving of the king and the priest , that image was carved into their brains and released during the stress of the battle . He laughed at the notion of Dark Yugi being a king from 3000 years earlier and declared Dark Yugi to be a prisoner , bound by a chain of the past . Kaiba activated " Card of Demise " , raising the number of cards in his hand to five and Set " Magical Trick Mirror " . Having Dueled Dark Yugi three times before , Kaiba considered himself to be thoroughly familiar with his strategies and capable of seeing through his Deck . He examined Dark Yugi ' s face - down cards and suspected that they must consist of something to raise the ATK of " Dark Magician " and a Trap Card , triggered by " Blue - Eyes " attacking , which he figured would be " Spellbinding Circle " . He Summoned " Lord of D . " , making his Dragon s immune to magic , including " Spellbinding Circle " . Turn 17 : Dark Yugi Dark Yugi Summoned " Beta the Magnet Warrior " , in Defense Mode . Since " Lord of D . " had thrown off his plan , he attacked it with " Dark Magician " ; a move which Kaiba had predicted . Kaiba activated " Magical Trick Mirror " , allowing him to play " Monster Reborn " from Dark Yugi ' s Graveyard , which he used to revive " The God of the Obelisk " in Defense Mode . " Obelisk " , acted as a shield , becoming the target of the attack . Having a higher DEF than the ATK of " Dark Magician " , Dark Yugi took the difference as damage ( Dark Yugi : 4000 → 1500 Life Points ) . Dark Yugi Set " Magic Cylinder " . Since " Monster Reborn " can only affect a God card for a single turn , " Obelisk " returned to Kaiba ' s Graveyard at the end of the turn . Turn 18 : Kaiba Kaiba vowed to crush Dark Yugi this turn , along with the visions of his own past in his heart . Dark Yugi considered that Kaiba might be correct about him wallowing in the past , but even so thought he could not move forward without what his lost memories were . Kaiba declared this to be the final turn and activated " The Flute of Summoning Dragon " to Summon his other two " Blue - Eyes White Dragons " . With only two monsters , both weaker than " Blue - Eyes White Dragon " , Dark Yugi worried that he was unable to defend himself and wondered if it was all over . Kaiba warned Dark Yugi to brace himself and carve Kaiba ' s name into his memories as the name of the true winner . He declared a triple attack with the three Dragons . Dark Yugi briefly shut his eyes in anticipation of defeat , but opened them upon hearing Jonouchi ' s voice , telling him not to lose . An apparition of Jonouchi appeared next to him and reiterated that Dark Yugi had always thought him that there is always a chance while you still have cards in your hand and that a true Duelist never gives up . Dark Yugi looked at his hand , which contained the " Red - Eyes Black Dragon " card , which had belonged to Jonouchi . The sound of " The Flute of Summoning Dragons " affects Dragons in both players hands , so Dark Yugi Special Summoned " Red - Eyes Black Dragon " . Kaiba remembered Yugi using that card when Jonouchi was brainwashed and had not realized it had been in his hand . Kaiba continued his triple attack . The first " Blue - Eyes White Dragon " attacked " Dark Magician " and Dark Yugi responded with " Magic Cylinder " , redirecting the attack . With " Lord of D . " on the field , Kaiba pointed out that the move was useless against his Dragons . However Dark Yugi was aware and selected " Lord of D . " as the target of the redirected attack . The second " Blue - Eyes White Dragon " attacked " Red - Eyes Black Dragon " and Dark Yugi activated " Spellbinding Circle " . With the absence of " Lord of D . " , he was free to target the attacking " Blue - Eyes White Dragon " ( " Blue - Eyes White Dragon " : 3000 → 2300 ATK ) , weakening it enough for " Red - Eyes Black Dragon " to destroy it ( Kaiba : 2000 → 1900 Life Points ) . The thought of his " Blue - Eyes " losing to a mere ghost irritated Kaiba . Dark Yugi thanked the apparition of Jonouchi for giving him strength . The apparition reciprocated some more encouragement before leaving . Just then the real Jonouchi regained his consciousness . The third " Blue - Eyes White Dragon " attacked and destroyed " Beta the Magnet Warrior " . Although the emergence of " Red - Eyes Black Dragon " interfered with his plan , Kaiba remained confident he would win . He suspected Dark Yugi would try to outlast him by playing in Defense Mode and in preparation Set " Final Attack Orders " and " Polymerization " . Upon familiarizing himself with the recent happenings , Jonouchi insisted that he and his friends go to the Duel Tower to support Dark Yugi . Turn 19 : Dark Yugi Dark Yugi drew " Double Spell " and Set it along with " De - Fusion Dark Yugi switched " Red - Eyes Black Dragon " to Defense Mode , but Kaiba activated " Final Attack Orders " , forcing all monsters into Attack Mode . Its other effect caused each player to send all but three cards of their choosing to their Graveyards . Kaiba affirmed that he did not need three turns to win , but Dark Yugi could place his futile hope in the cards he choose . " Monster Reborn " was among the cards chosen by Kaiba . Wondering what cards Kaiba choose , Dark Yugi noted that he had not played " Monster Reborn " yet and worried that he could have it and " Polymerization " . Turn 20 : Kaiba Kaiba confirmed Dark Yugi ' s suspicions and used " Monster Reborn " to revive the destroyed " Blue - Eyes White Dragon " and used his face - down " Polymerization " to fuse it with the other two , forming " Blue - Eyes Ultimate Dragon " . Dark Marik believed that this meant Kaiba would win . He had not expected that outcome before , but resigned that it did not matter , since he planned on killing both players , regardless of who won . Kaiba claimed that he was about to defeat Dark Yugi and achieve something great , which was not something as simple as revenge . He said that had fought through Battle City to find out why he was fixated on defeating Dark Yugi and had finally found the answer . Unlike Dark Yugi , who was in pursuit of the past , Kaiba ' s stated that his past was filled with hatred and anger , which continued to exist even after he got revenge on his adoptive father , Gozaburo . In order to pave his future future , he planned on stamping out the past , including Dark Yugi , whom he considered to be a creature of the past . Mokuba worried that if Kaiba forgot about the past , he might forget the smile he showed him long ago . Dark Yugi replied that Kaiba was one of the few people he recognized as a Duelist , but he was a bit disappointed in him . Regardless of how much hatred or anger Kaiba had , he claimed that those things are not enough to beat him . He explained that like the Duel Tower standing on the rubble , Kaiba could pile hate on top of hate to reach the top , but will never find true victory this way ; he will only wander forever seeking the next thing to hate . Dark Yugi activated " Double Spell " , allowing him to use the Spell Card s used by Kaiba this turn . He used " Monster Reborn " to revive " Buster Blader " and " Polymerization " to fuse it with " Dark Magican " , forming " Dark Paladin " , which gained 500 ATK for each Dragon on the field ( " Dark Paladin " : 2900 → 3900 ATK ) . Since Fusion Monster s could not attack the turn they are Summoned , Kaiba ended his turn without attacking . Turn 21 : Dark Yugi Even with his face - down " Magic Formula " , " Dark Paladin " would not be strong enough to defeat " Blue - Eyes Ultimate Dragon " , so Dark Yugi placed his chances on the next card he drew . Turn 22 : Kaiba Kaiba drew " Absorb Spell " and Set it . Kaiba warned Dark Yugi to brace himself threatened to bury Dark Yugi , him with his own detestable past . He vowed to surpass everything and rise to a higher plain , repeating that he alone will be the King of Duelists . Dark Yugi restated his stance that with that motivation , Kaiba would only find himself in an endless chain of hatred , but Kaiba affirmed that hatred and anger have always given him to power to dominate everything . Dark Yugi urged him to attack with all that hatred , if he thought he could win with it . Seeing Kaiba as both a rival and a friend , Dark Yugi still hoped to exorcise his madness . " Blue - Eyes Ultimate Dragon " attacked , using its ability to attack three enemies at once . Dark Yugi activated " Magic Formula " to increase the ATK of " Dark Paladin " and Kaiba responded with " Absorb Spell " , transferring the power boost to " Blue - Eyes Ultimate Dragon " ( " Blue - Eyes Ultimate Dragon " : 4500 → 5000 ATK ) . Dark Yugi then activated " De - Fusion " , splitting the " Ultimate Dragon " back into three " Blue - Eyes White Dragons " . This increased the number of Dragons on the field to four , further increasing the ATK of " Dark Paladin " ( " Dark Paladin " : 3900 → 4900 ATK ) . Turn 23 : Dark Yugi Dark Yugi activated " Diffusion Wave - Motion " , paying 1000 Life Points ( Dark Yugi : 1500 → 500 Life Points ) to convert the attack from " Dark Paladin " into a wave , making it hit all enemy monsters . " Dark Paladin " attacked and destroyed all three " Blue - Eyes " ( Kaiba : 1900 → 0 Life Points ) , winning the Duel for Dark Yugi , who declared hatred to be a dead end . Aftermath . Kaiba was stunned and reflected on his goals ; rising above hatred for Gozaburo , defeating Dark Yugi and claiming the title of King of Duelists , as he watched the Solid Vision projections of his destroyed " Blue - Eyes White Dragon s " fade away . When the reality of his loss hit him , he briefly re - evaluated his strategy and saw no flaws in his Deck , combos or tactics . Dark Yugi professed that although one of them lost and the other won , there was no difference in their abilities , but Kaiba was insulted , as he interpreted this as pity . Dark Yugi acknowledged Kaiba ' s talent as a Duelist and accredited his defeat to the demon , " hatred " . He explained that by having sadness , hatred and anger in his heart , Kaiba was also fighting his own inner enemies and once all of them are defeated , Kaiba would open himself to the road of true Duelists . Dark Yugi drew attention to the fact that he would have lost the Duel , without " Red - Eyes Black Dragon " , a card he safe kept for a friend , and concluded that the power of friendship brought him victory . But Kaiba considered that to be nonsense and saw friendship as an abstract concept , meaningless in achieving victory . Regarding the winner as the only one with the right to talk , Kaiba said he would keep quiet . Per the ante rule , he threw the card , " The God of the Obelisk " over to Dark Yugi . Having been defeated by Dark Yugi , he refused to allow Dark Yugi to lose the next Duel . Cards used . The following cards were used in this Duel :
