Yu - Gi - Oh ! - Episode 063 " Playing with a Parasite , Part 1 " , known as " The Trap of Revenge - Rampage ! Paraside " in the Japanese version , is the sixty - third episode of the " Yu - Gi - Oh ! " anime . It aired in Japan on July 10 , 2001 , and in the United States on February 15 , 2003 . Summary . Joey Wheeler is standing around when he is addressed by a kid who wants his autograph . As he signs it , the kid notices his Duel Disk , the symbol of being such a strong and noteworthy Duelist , and asks if he can hold it . Flattered , Joey complies , but not until he stops bragging does he look up and notice that the kid is running away with his disk . He chases him , but the kid is collared by Tristan , who was with Tea and Solomon Moto and had noticed the chase . The four of them question the kid , and he confesses he wanted to become a strong Duelist , but all of his cards were stolen . When pressed for a description of the thief , he describes Weevil Underwood , and Joey immediately runs off to find Weevil for a little payback . Once everyone is gone , the kid smirks and sneaks off to an alley . Weevil is waiting there , and when the kid reports that he did everything as planned , Weevil rewards him with a card . It turns out to not be a rare or valuable card ( merely a " Gokibore " ) , but the kid ' s protests are cut off by a shot from a slime gun Weevil is carrying . Weevil then walks away smiling . Still searching , Joey catches sight of Weevil and challenges him . Both of them have two locator cards , and each they wager both of them on the Duel . It becomes clear right away that Weevil hasn ' t lost his taste for Insect - swarming strategies , but Joey brings out his latest prize , " Jinzo " . Unfazed , Weevil uses multiple defensive cards to increase his Life Points , and his score rises to 5700 before Joey breaks the combo . It is only now that Weevil announces that his plan goes beyond his cards so far ; a parasite is already waiting to ruin Joey ' s monsters . After getting out " Larvae Moth " and equipping it with " Cocoon of Evolution " , Weevil activates " Reckless Parasite " to Special Summon " Parasite Paracide " from Joey ' s Deck , and this is met with disgust and consternation from Joey and the others , as Joey doesn ' t keep any Insect - Type monsters in his deck . They quickly realize that the kid from earlier put the parasite card in Joey ' s Deck under Weevil ' s orders when he briefly took Joey ' s Duel Disk . The situation gets worse when Weevil makes it clear that he is planning to Summon an ace monster to surpass the " Great Moth " he Summoned in Duelist Kingdom . He soon follows up his combo with " Insect Barrier " to seal off all of Joey ' s attacks and " Leghul " to inflict Battle Damage through direct attacks whenever he wants . Joey can do nothing but buckle down in preparation , and all too soon , the cocoon opens , and Weevil Summons the " Perfectly Ultimate Great Moth " . With nothing but low - level monsters and no ability to attack , Joey is in a tight spot , and Weevil only plans to make it worse . Featured Duel : Joey Wheeler vs . Weevil Underwood , Part 1 .
