Despite Haga fixing the Duel , by having the card " Parasite Paracide " slipped into Jonouchi ' s Deck , Jonouchi managed to win . Events . Prior . Haga arranged for a boy to steal Jonouchi ' s Duel Disk and sneak two " Parasite Paracide " cards into his Deck . When Jonouchi caught the boy , he lied about being a tournament Duelist , whose own Deck and Duel Disk had been stolen . Jonouchi bought the story and offered to Duel the alleged thief , so the boy left in order to fetch Haga . Sugoroku Mutou , who had been skeptical of the boy ' s story , suggested that Jonouchi check his Deck to make sure he had not stolen anything . Jonouchi felt that he was being too cynical and that people need to have more faith . The boy returned to Haga and reported that everything had gone according to plan . Instead of giving the boy a rare card , as he had promised , Haga gave him a common " Pillroach " and sprayed him in the face with bug killer when he protested . Haga advanced to face Jonouchi , hoping that defeating him would attract the attention of his friend , Yugi Mutou , whom Haga hoped to subsequently defeat in revenge for Duelist Kingdom . Remembering what Haga did to Yugi ' s " Exodia " cards one the way to Duelist Kingdom , Anzu Mazaki tried to talk Jonouchi out of accepting the Duel , saying that Haga did not deserve the honor . However Jonouchi felt it was necessary for him to defeat Haga to serve karma for stealing the boy ' s Deck . Anzu was uncomfortable by the way Haga was laughing and warned Jonouchi that he could be up to something . Jonouchi insisted that only cowards run and that in this Duel he would be fighting for courage to give to his sister , Shizuka Kawai . Each player wagered two Puzzle Cards and one rare card . Jonouchi and Haga ' s respective rare cards being " Time Wizard " and " Insect Queen " . The Duel . 1st turn : Jonouchi Jonouchi Summoned " Panther Warrior " and ended his turn . 2nd turn : Haga Haga Set " Insect Barrier " and Summon ed " Skull - Mark Ladybug " in Defense Mode . 3rd turn : Jonouchi Jonouchi Summoned " Little Winguard " . " Panther Warrior " attacked and destroyed " Skull - Mark Ladybug " , whose effect caused Haga to gain 500 Life Points ( Haga : 4000 → 4500 Life Points ) . 4th turn : Haga Haga Summoned " Pinch Hopper " in Defense Mode . 5th turn : Jonouchi Jonouchi planned on sacrificing his two monsters to Summon " Jinzo " . However in his Draw Phase , he drew " Parasite Paracide " , a card the boy had slipped into his Deck . Jonouchi was forced to Summon " Parasite Paracide " due to its own effect . His monsters , " Panther Warrior " and " Little Winguard " became its hosts , causing them to become part - Insect . As Jonouchi and his friends realized that Haga had gotten the boy to interfere with Jonouchi ' s Deck , Haga stated that a brilliant tactician starts his strategy before the battle begins . Jonouchi tried to continue with his original plan to Summon " Jinzo " , but Haga explained that infected monsters cannot be sacrificed . Instead Jonouchi tried attacking with his monsters , but Haga activate d his face - down " Insect Barrier " . With all his monsters treated as Insects , Jonouchi was left with no way of attacking . 6th turn : Haga Haga activated " Insecticide " , destroy ing his own " Pinch Hopper " . This activated its effect , allowing him to Summon " Insect Queen " from his hand . The queen gained 400 ATK for every other Insect on the field ( " Insect Queen " : 2200 → 3400 ATK ) . " Insect Queen " attacked and destroyed " Little Winguard " ( Jonouchi : 4000 → 2000 Life Points ) . As she destroyed a monster , she laid an egg , an " Insect Larva " ( " Insect Queen " : 3400 → 2900 → 3400 ATK ) . 7th turn : Jonouchi Since his monsters would be unable to attack and would make " Insect Queen " stronger , Jonouchi did not Summon anything and Set " Magic Arm Shield " . As Jonouchi ended his turn , Sugoroku reminded him that he forgot to switch his current monsters to Defense Mode , but Haga said it was too late , as he had already declared the end of his turn . Jonouchi had done this on purpose , but acted as though he had made a mistake , in order to lead Haga on . 8th turn : Haga Sugoroku calculated that if Haga attacked " Parasite Paracide " with " Insect Queen " , Jonouchi would lose . Haga on the other hand , opted to attack " Panther Warrior " with " Insect Queen " and then attack the parasite with " Insect Larva " , which would also result in Jonouchi losing , if successful . " Insect Queen " attacked " Panther Warrior " , which Jonouchi had predicted , knowing Haga would leave his own card , the parasite until last . He explained that he had set the Trap " Magic Arm Shield " on " Panther Warrior " for that purpose and then activated it , causing " Insect Queen " to attack " Insect Larva " instead , destroying it ( Haga : 4500 → 2300 Life Points , Insect Queen : 3400 → 2900 ATK ) . 9th turn : Jonouchi Jonouchi still had the dilemma of " Parasite Paracide " making anything he could Summon unable to attack and causing them to strengthen " Insect Queen " . Haga remarked that the parasite could infect almost anything humanoid or animal , which should accommodate for the monsters in Jonouchi ' s Deck . Sugoroku was aware of at least one Warrior monster which could not be affected and wondered if it was in Jonouchi ' s Deck . Jonouchi switched his monsters to Defense Mode and ended his turn . 10th turn : Haga Haga Summoned " Soldier Ari " in Defense Mode ( " Insect Queen " : 2900 → 3400 ATK ) . " Insect Queen " attacked and destroyed " Panther Warrior " and laid another " Insect Larva " ( " Insect Queen " : 3400 → 2900 → 3400 ATK ) . 11th turn : Jonouchi Jonouchi drew " Gearfried the Iron Knight " and said that he had found a weakness in Haga ' s Insect combo . He played " Graverobber " face - down and Summoned " Gearfried " . " Parasite Paracide " tried to infect " Gearfried " , but could not penetrate its iron . Uninfected " Gearfried " was not an Insect and therefore unaffected by " Insect Barrier " . Haga ' s Larva were born in Attack Mode , incapable of defending . " Insect Barrier " had been used to shield them . Having overcome the shield , Jonouchi used " Gearfried " to attack and destroy an " Insect Larva " to pick away at Haga ' s Life Points ( Haga : 2300 → 1700 Life Points , " Insect Queen " : 3400 → 2900 ATK ) . 12th turn : Haga Haga asked if Jonouchi was prepared to pay the price for angering the queen and said that he would now show him the Deck ' s deadliest move , the " Queen Impact " . He switched " Soldier Ari " to Attack Mode and activated " Multiplication of Ants " , Summoning nine " Army Ant s " ( " Insect Queen " : 2900 → 6600 ATK ) . " Insect Queen " attacked " Gearfried " , but Jonouchi activated " Graverobber " , taking " Insecticide " from Haga ' s Graveyard and using it to destroy " Insect Queen " . 13th turn : Jonouchi Jonouchi attacked Haga directly with " Gearfried " ( Haga : 1700 → 0 Life Points ) . Aftermath . Haga asked how he could lose to an amateur like Jonouchi . Jonouchi replied that it is not that he is strong , but that Haga is just too weak .
