Yugi Mutou and Brainwashed Jonouchi ' s Duel ( manga ) Yugi Mutou faced Katsuya Jonouchi in a game of " Duel Monsters " , during the Battle City tournament , in the " Yu - Gi - Oh ! " manga . Jonouchi was controlled by Marik Ishtar for most of the Duel , and initially fought against Dark Yugi . After a few turns , Yugi , believing himself to be capable of returning Jonouchi to his former self , took over from Dark Yugi . The Duel was set in such a way that the losing player would be dragged to the bottom of the sea . It was intended , by Marik , as a means of defeating and killing Dark Yugi . However Yugi ' s restoration of Jonouchi ' s mentality and the resulting DRAW led to the survival of both participants . Events . Prior . Marik Ishtar got his Rare Hunter underlings to keep an eye on Yugi and Dark Yugi ' s friends , Katsuya Jonouchi , Anzu Mazaki , Ryo Bakura and Sugoroku Mutou , during the preliminary stages of the Battle City tournament . He first alerted Dark Yugi of this after he Dueled him through the Doll and warned him that he had better find them before something bad happened . Using his satellites , Seto Kaiba helped Dark Yugi locate Jonouchi , rationalizing that he did it to locate the Rare Hunters , rather than help Yugi . Marik traveled to Domino City Aquarium , where he hoped to subject Jonouchi to his Millennium Rod ' s mind control powers . However he was interrupted by Dark Bakura , who agreed to help Marik defeat Yugi , in exchange for the Millennium Rod . Dark Bakura injured his host , Ryo Bakura , who then received aid from Marik , under the alias " Namu " , allowing Marik to earn the trust of Jonouchi and Anzu . Shortly afterwards , Marik , brought them into contact with the Millennium Rod , allowing him to brainwash them . He implanted his own hatred in Jonouchi , making Jonouchi completely loyal to him and living to kill Dark Yugi . Following the Explosive Tag Team Match of Death , Marik possessed Mask of Light to inform Dark Yugi that he had his friends ready for the next phase of his plan , where Dark Yugi was to Duel Jonouchi on the Stage of Death . Kaiba was interested in seeing how Dark Yugi , who had strong philosophies in unity , would cope when forced to battle a friend . When Kaiba was collected on his helicopter , he brought Dark Yugi with him to Jonouchi ' s then location , Domino Pier . At the pier , Marik instructed two of his Rare Hunters to improve Jonouchi ' s Deck , by loading it with illegal direct damage cards . Capable of controlling his " dolls " with the Millennium Rod from a distance , Marik departed to the location of the tournament finals , leaving Jonouchi and Anzu under the supervision of his Rare Hunters . When Dark Yugi arrived , he discovered that Jonouchi had been brainwashed . He made unsuccessful attempts to snap Jonouchi out of it , but Jonouchi challenged him to a life or death Duel . As Jonouchi led Dark Yugi to the stage for their Duel , Marik spoke through Anzu and advised Dark Yugi to cooperate or he would force Anzu to swallow a suicide capsule . Dark Yugi and Jonouchi were handcuffed to a 300 kg ( about 660 lbs ) anchor hanging from two cranes above their stage . A bomb , set to detonate 15 seconds after a player ' s Life Points dropped to to 0 or 40 minutes after the beginning of the Duel , was attached to the anchor . Once detonated , the bomb would release the anchor , dragging anyone cuffed to it to the bottom of the sea . In order to survive , a player would have to defeat their opponent , which would unlock a box containing a key to their handcuff . They could then use the 15 seconds to free themself . Kaiba was disgusted by the nature of the Duel and planned to intervene , but one of the Rare Hunters took Mokuba Kaiba at knife point and warned Kaiba to stay put . As Marik did not want the " Slifer the Sky Dragon " card to be pulled into the water , Jonouchi ordered Dark Yugi to take it out of his Deck . The card was in a box attached to his belt , rather than his Deck . As he removed the belt , he took the " Red - Eyes Black Dragon " card , which had previously belonged to Jonouchi , from the box and added it to his Deck . Duel . 1st turn : Dark Yugi Dark Yugi worried about how he could fight , knowing it could result in one of them dying . Jonouchi urged him to hurry up and he Summoned " Baphomet " in Defense Mode . 2nd turn : Jonouchi Jonouchi activated " Raigeki " , destroying " Baphomet " and surprising Dark Yugi and Kaiba , who both recognized that card as being banned . Jonouchi Summoned " Alligator Sword " and used it to attack Dark Yugi directly ( Dark Yugi : 4000 → 2500 Life Points ) . 3rd turn : Dark Yugi Dark Yugi Summoned " Big Shield Guardna " in Defense Mode . 4th turn : Jonouchi Jonouchi commented on Dark Yugi playing a " wall " monster , noting that while the shield may be big , it would not stop a fireball . He activated " Hinotama " , another banned card , directly inflicting 600 damage to Dark Yugi ( Dark Yugi : 2500 → 1900 Life Points ) . As Jonouchi laughed , Dark Yugi promised himself to not give up and to win Jonouchi ' s heart back . 5th turn : Dark Yugi Dark Yugi drew " Spellbinding Circle " . He Set it and Summoned " Kuriboh " in Attack Mode . 6th turn : Jonouchi Jonouchi thought that playing " Kuriboh " in Attack Mode was suicide and guessed that Dark Yugi had decided to die in order to save him . However Dark Yugi insisted that he would not die and would not let Jonouchi die either . " Alligator Sword " attacked " Kuriboh " , but Dark Yugi activated " Spellbinding Circle " , immobilizing " Alligator Sword " and reducing its ATK ( " Alligator Sword " : 1500 → 800 ATK ) . Jonouchi was not too off put , as he stated that he was fighting Dark Yugi not his monsters . He then activated another " Hinotama " ( Dark Yugi : 1900 → 1300 Life Points ) . Dark Yugi asked if Jonouchi could not feel pain in his Duelist ' s heart . Jonouchi had no idea what he was talking about . Dark Yugi explained that the pain he was feeling was not from being burned by Jonouchi ' s cards , but from seeing him lose his heart as a Duelist . Yugi began to speak with Dark Yugi . He said that he had never felt Dark Yugi hurt so much before and offered to halve the pain , by asking if he could Duel Jonouchi instead . Explaining that Jonouchi had always helped him before , even by risking his life , Yugi wanted to take his turn to help Jonouchi . Dark Yugi objected that the Duel was too difficult and was more like fighting Marik than Jonouchi . Yugi understood and reminded Dark Yugi that he had once said that Yugi ' s wish for friends had been fulfilled by his own endeavor not by the Millennium Puzzle . He wanted to prove that in this battle , by getting back Jonouchi ' s heart . Dark Yugi accepted but said that he would take over if Yugi ' s life got to be in serious danger . 7th turn : Yugi Yugi introduced himself as Jonouchi ' s new opponent , much to Marik ' s displeasure . Marik wished to kill the pharaoh and would not be satisfied with simply killing the " vessel " . He had Jonouchi order Yugi to bring Dark Yugi back , but Yugi said " too bad " and began his turn . Dark Yugi notified Yugi that there was one card in their Deck that could rescue Jonouchi ' s heart . Yugi was aware and managed to draw it , the " Red - Eyes Black Dragon " . Yugi ' s hand contained " Red - Eyes Black Dragon " , " Card Destruction " , " Exchange " and " De - Spell " . Before Summoning " Red - Eyes Black Dragon " , Yugi wanted to make sure that Jonouchi ' s true self remained . He asked Dark Yugi to remain quiet while he made his next move . Yugi activated " Exchange " , so both players were to show each other their hands and take a card from their opponent . Jonouchi suspected Yugi ' s hand must only contain junk , but was surprised to see " Red - Eyes Black Dragon " . Marik had been under the impression that Yugi was inexperienced and now thought he was even more foolish than he had suspected , as he was giving away a rare card , so easily . Marik commanded Jonouchi to take " Red - Eyes Black Dragon " . However Jonouchi hesitated and following some internal struggling , took " Card Destruction " instead . He insisted that he did not need any Monster Card s and that " Card Destruction " was sufficient to crush Yugi . Yugi took " Magic Arm Shield " from Jonouchi . Yugi declared that he knew for sure that Jonouchi had not lost his heart as a Duelist . He reasoned that Jonouchi had promised to not use " Red - Eyes Black Dragon " , until his Duel with Dark Yugi and that was why he could not take it . Jonouchi claimed that was nonsense and told him to shut up . Yugi Sacrificed " Kuriboh " and " Big Shield Guardna " to Summon " Red - Eyes Black Dragon " . He asked if Jonouchi could see that the dragon ' s eyes had been stained with the color of sadness . He announced that he and " Red - Eyes " both wanted Jonouchi to by himself again and would fight if necessary . " Red - Eyes " attacked and destroy ed " Alligator Sword " ( Jonouchi : 4000 → 3100 Life Points ) , but Jonouchi was unphazed by the damage . 8th turn : Jonouchi Jonouchi declared that he would keep using illegal Spell Card s , until Yugi was dead . Dark Yugi grew concerned and wanted to take over , but Yugi took off the Millennium Puzzle , removing Dark Yugi ' s ability to take control . Despite having learned courage from Dark Yugi , Yugi still felt cowardly at times and needed to handle this himself in order to overcome that . Dark Yugi objected that Yugi could die and that the situation required incredible skill . Yugi agreed , but trusted Jonouchi and thought that if he did not become stronger by himself , Dark Yugi would never be able to leave him . Jonouchi activated another " Hinotama " ( Yugi : 1300 → 700 Life Points ) . Concerned by the threat " Red - Eyes Black Dragon " posed , Jonouchi Summoned " Rocket Warrior " . He used its power to transform itself into a rocket and deal 1500 damage to " Red - Eyes " via an attack ( " Red - Eyes Black Dragon " : 2400 → 900 ATK ) . Marik laughed that it was now just a dying dragon with 900 ATK and nothing to fear . Yugi made his way across the stage and gave Jonouchi the Millennium Puzzle . He did not want it to sink to the bottom of the bay and asked that Jonouchi hold on to it when the time comes . Marik thought that it was foolish of Yugi to hand over his most precious possession and figured it was evidence that he had given up . Marik ordered Jonouchi to take the puzzle apart and throw the pieces into the sea , fulfilling his revenge for 3000 years of slavery in his clan in the name of the pharaoh . Jonouchi removed a piece and prepared to throw it away . However this reminded him of a similar scenario , where he had thrown a piece of the puzzle away before , in the events leading up to him becoming friends with Yugi . Jonouchi struggled with conflicting feelings and eventually put the piece back on the puzzle . When Marik asked how he could disobey him , Jonouchi replied that he is a Duelist , that he had no interest in revenge or what happened 3000 years ago and that he was going to settle this in a Duel . Vexed by the defiance , Marik decided to not let Jonouchi live , after winning the Duel . 9th turn : Yugi With Marik ' s brainwashing gradually wearing off , Yugi felt his plan was going to work . With 14 minutes left before the bomb was due to detonate , he began his turn . Thinking he knew what Dark Yugi would do , Yugi Set " De - Spell " and " Magic Arm Shield " and Summoned " Beta the Magnet Warrior " . 10th turn : Jonouchi Marik thought that Yugi had made a foolish mistake , by leaving the weakened " Red - Eyes Black Dragon " in Attack Mode . Jonouchi drew " Panther Warrior " and Marik thought this was perfect , because if " Panther Warrior " could defeat " Red - Eyes " they would win . Jonouchi Summoned " Panther Warrior " and " Rocket Warrior " switched to its rocket form . Marik ordered Jonouchi to eliminate " Red - Eyes " . " Panther Warrior " began to attack , but Jonouchi had it target " Beta " instead . Yugi activated " Magic Arm Shield " , the card he had taken from Jonouchi with " Exchange " . " Beta " held onto the shield , whose magic arm gripped onto " Rocket Warrior " , making it the new target of the attack . " Rocket Warrior " was not destroyed and dealt 1500 damage to " Panther Warrior " ( " Panther Warrior " : 2000 → 500 ATK ) . 11th turn : Yugi Yugi Sacrificed " Beta the Magnet Warrior " to Summon " Archfiend of Gilfer " and used " Archfiend of Gilfer " to attack and destroy " Rocket Warrior " ( Jonouchi : 3100 → 2400 Life Points ) . Jonouchi still remained under Marik ' s influence . Yugi thought that " Red - Eyes " was the only monster capable of doing anything about it , but it was too injured to even stand up . As there was only 10 minutes left , Kaiba grew anxious and decided he must take a risk and intervene . 12th turn : Jonouchi Jonouchi ' s hand contained " Graceful Dice " , " Card Destruction " , " Time Wizard " and the " Skull Dice " , he just drew . Marik instructed him to just keep quiet and wait for the Duel to end . Yugi asked Jonouchi reminded Jonouchi of the promise he made after Duelist Kingdom , wherein to makeup for taking the prize money , Jonouchi would owe Dark Yugi one until the day he beats Dark Yugi . This caused Jonouchi to have flashbacks from the time of Shizuka Kawai ' s eye operation , which had been funded by the money and the time he promised to Duel Dark Yugi . Jonouchi forsook Marik ' s order again and continued to Duel , Setting " Skull Dice " and " Graceful Dice " . 13th turn : Yugi Yugi drew " Mystical Rift Panel " and Set it . " Archfiend of Gilfer " attacked " Panther Warrior " , which Jonouchi had left in Attack Mode to lure Yugi into attacking . Jonouchi activated " Skull " and " Graceful Dice " , targeting " Archfiend of Gilfer " and " Panther Warrior " , respectively . Yugi used " De - Spell " , negating the effect of " Graceful Dice " . A 1 was rolled for " Skull Dice " , so it had no effect . " Archfiend of Gilfer " destroyed " Panther Warrior " in battle ( Jonouchi : 2400 → 700 Life Points ) . With both players on equal Life Points , Yugi considered the possibility of them both escaping if their Life Points went to 0 at the same time . With 3 minutes and 49 seconds left , Kaiba decided to take action . He drew the top card from his Deck , hoping it would be a common card , but got " Blue - Eyes White Dragon " , which he immediately flung at the Rare Hunter holding Mokuba . The card became lodged in the Ghoul ' s hand , causing him to drop his knife in pain . Mokuba broke free and Kaiba attacked the two Rare Hunters , took back his card and forced both hunters into the water . He then ran towards the stage . 14th turn : Jonouchi Jonouchi drew " Meteor of Destruction " , another direct damage card , capable of expunging the remainder of Yugi ' s Life Points . Marik told him if he wanted to beat Yugi bad enough , he could play the card and spare his own life . He urged him to play the card , step out of Yugi ' s shadow by killing him and then have the Duel branded into his memories . Struggling with his inner conflicts , Jonouchi finally told Marik to shut up and that he did not want to have that in his memories . Slightly taken aback , Marik said to do nothing in that case and die happily together with Yugi , when the time runs out . Yugi called out to Marik and declared him the true loser of the Duel . While Marik could implant evil thoughts in Jonouchi ' s mind , Yugi believed that Jonouchi would not give in . He remained convinced that he could turn Jonouchi back to normal in the one remaining minute . He exclaimed that when he achieves that , even if he and Jonouchi both die , Marik will have the fact that he lost burned into his memories forever . With little time left , he urged Marik to give him his best shot . Marik reciprocated , issuing another command to Jonouchi to play " Meteor of Destruction " . Jonouchi resisted , but Marik pushed all his vengeance into the card , forcing Jonouchi to play it . Jonouchi then snapped free and yelled at Yugi to not die . Yugi smiled and replied that he would not . He activated his " Mystical Rift Panel " , allowing him to choose the target of " Meteor of Destruction " . Marik became enraged , thinking Yugi was about to win . Jonouchi back to his former self , asked why they were fighting . Yugi removed his Duel Disk and happy to see Jonouchi back , informed him that the Duel was just over and that they were not really fighting each other . Yugi clarified that Jonouchi had been fighting Marik ' s influence , while he had to fight himself to ensure he remained friends with Jonouchi . With 12 seconds left , he admitted to playing " Mystical Rift Panel " to buy the time needed to thank Jonouchi for teaching him courage and that he was not alone and to say that Jonouchi was his best friend and he loved him . In the final second , Yugi choose himself as the meteor ' s target , reducing his Life Points to 0 , giving Jonouchi access to his key . Before falling unconscious , Yugi told Jonouchi to use the next 15 seconds to unlock himself . However Jonouchi refused to leave Yugi and run . He noticed " Red - Eyes Black Dragon " and asked it to attack him . " Red - Eyes " complied and Jonouchi ' s Life Points also dropped to 0 , opening the box containing Yugi ' s key . Aftermath . With 2 seconds before the anchor dropped , Jonouchi took off the Millennium Puzzle and his Duel Disk . With no time to get his own key , he swung from the chain attaching him to the anchor over to Yugi ' s side of the stage and grabbed Yugi ' s key , just as the bomb released the anchor . While both players were pulled underwater , Jonouchi used the key to unlock Yugi ' s cuff and let him float to the surface . He apologized to Yugi and called him a real friend . Seeing that the key would not fit his own handcuff , Jonouchi suspected he had reached the end of his life . On the surface , Mokuba pulled Yugi out of the water and reported that he was unconscious , but alive . Kaiba then picked up the other key and laughing that Jonouchi must now be at his limit , dropped it into the water for Jonouchi . Thinking he was about to die , Jonouchi spotted the key and freed himself . Yugi woke up shortly before Jonouchi surfaced . Kaiba admitted to saving Jonouchi only because he admired his stupidity in forgetting to take his key , while in haste to remove his Duel Disk . He silently thought to himself that Jonouchi was finally a decent Duelist . Jonouchi was annoyed to have been saved by him , but said that he owed Kaiba one . Jonouchi apologized for what happened , but Yugi told him not to blame himself , as he had succeeded in protecting what was important to them . Anzu dropped the suicide capsule and Marik released control of her for the time being . She was unsure what she had been doing , but was greeted by Yugi and Jonouchi who were happy to see that she was okay . Cards used . The following cards appeared in this Duel :
