Yu - Gi - Oh ! Duelist - Duel 008 " The Ultimate Great Moth " , known as " Ultimate Perfect Form ! ! " in the Japanese version , is the eight chapter of " Yu - Gi - Oh ! Duelist " in the English version and sixty - seventh chapter of " Yu - Gi - Oh ! " in the Japanese version . This chapter was originally printed in the " Weekly Shōnen Jump " magazine in Japanese . It has been reprinted in in volume 1 of " Yu - Gi - Oh ! Duelist " and volume 5 of the bunkoban . Summary . Jonouchi , Honda , Bakura and Anzu celebrate Dark Yugi countering Haga ' s last move and destroying his monsters . Mai Kujaku , who only just arrived , admits it was a smooth move , but says " Yugi - chan ' s only taken a small lead " . Honda and Jonouchi are both enticed by Mai , who explains that in " Duel Monsters " a game can go from victory to defeat in a turn , so it ' s too early to get cocky . Anzu is irritated by Mai ' s interjection and tells Mai off for using the " chan " to refer to Dark Yugi . Mai explains that Haga is the Japanese champion and Anzu argues that Dark Yugi is a master planner with several winning strategies . Much to Anzu ' s annoyance , Jonouchi and Honda agree with Mai . Although Jonouchi is certain that Dark Yugi is going to win , he doesn ' t think he should let his guard down . Anzu looks over at Mai , thinking that Yugi ' s going to Duel her sometime . At the same time , Mai watches the Duel , hoping for Dark Yugi to show her all his tricks . Dark Yugi and Haga have 1350 and 450 Life Points respectively . Haga says that Dark Yugi will regret this and that he ' s made him mad . Dark Yugi replies that talk is cheap and encourages Haga to channel his frustration at him through his cards . Haga thinks to himself that Dark Yugi is the one talking big , but he still has his ultimate weapon in his Deck and when he plays it victory will be his and Dark Yugi will not escape death . Dark Yugi teases Haga saying his side of the field looks a bit empty and maybe he should Summon a monster . Angrily Haga plays " Larvae Moth " in Defense Mode . Dark Yugi notes how weak the card is and suspects Haga is planning a combo attack . Determined not to fall for it , he suspects Haga ' s face - down Trap Card is part of it . He thinks if he attacks , he runs the risk of all his monsters being destroyed . Instead he plays " Monster Recovery " , returning " Dark Magician " , " Saiga " and an unnamed monster and his hand to his Deck and draw ing 5 new cards . From his new cards , he Summons the weakest one , " Kuriboh " and attack s with it . Haga ' s Trap Card automatically activates , destroy ing " Kuriboh " , at no great cost to Dark Yugi , whose Life Points drop to 1050 . Finally Dark Yugi plays " Beaver Warrior " in Defense Mode and ends his turn . Haga laughs that Dark Yugi has done exactly what he wanted him to do . He then plays " Cocoon of Evolution " equip ping it to " Larvae Moth " , which becomes surrounded in a giant cocoon . Haga excitedly explains that over the next five turns , " Larvae Moth " will gradually evolve into " Ultimate Perfect Great Moth " , which will be invulnerable . The cocoon has 2000 DEF , which becomes 2600 due to the Forest . Dark Yugi realizes he must destroy the cocoon before it hatches in five turns . He Summons " Gaia the Fierce Knight " , which has 2300 ATK and has it attack the cocoon with " spiral Saber " . ( In the English version , the ATK of " Gaia " is misprinted as 2000 . ) The attack just bounces back and Dark Yugi ' s Life Points drop to 750 . Jonouchi and Anzu start to worry , while Mai thinks nobody has ever beaten the " Cocoon of Evolution " combo and wonders what Dark Yugi will do . Dark Yugi thinks that none of his cards are good in the Forest and any multiple card combo with the cards in his current hand can ' t surpass the cocoon ' s DEF . Haga is unable to Summon more monsters while the cocoon is in play , so he passes his turn , leaving just two more turns until the " Ultimate Perfect Great Moth " hatches . Dark Yugi worries that he still hasn ' t found a solution . However Jonouchi leans against the Battle Box and reminds Dark Yugi that they came to the island to win the Honors of the Duelist King . He says that Dark Yugi can ' t lose and should burn down the Forest if necessary to take out the cocoon . Mai calls Dark Yugi ' s friends amateurs . She exclaims that once a Duelist sits down for a game the only person they can believe in is themself and a real Duelist wouldn ' t pay attention to them cheering for him . Anzu disagrees that Yugi will listen , hear their feelings and win . Mai is unconvinced , but notices how confident Dark Yugi suddenly looks . Dark Yugi Summons " Curse of Dragon " , combos it with " Burning Land " and attacks with " Flames of Hell " . Haga yells that it is no good , " Curse of Dragon " has 600 less ATK than the DEF of " Cocoon of Evolution " . However Dark Yugi laughs and explains that he was not attacking the cocoon and his true target was the forest , which has now been burnt away . Without its Field Power Source , the cocoon ' s DEF returns to normal . Dark Yugi then attacks the cocoon with " Gaia " , cutting it open . Jonouchi and Honda celebrate the destruction of the cocoon , but Bakura notices something still alive in it . The evolution stage four , " Great Moth " , with 2600 ATK and 2500 DEF , comes out of the cocoon . Haga laughs that it didn ' t make it to ultimate perfect form , but it ' s still strong . Dark Yugi smirks and exclaims that when he sees a tough monster , he gets excited . Haga Summons " Larvae Moth " in Defense Mode in the Forest ( DEF : 400 → 520 ) . Dark Yugi plays " Monster Recovery " returning , " Dark Magician " , " Saiga " , an unnamed monster and his hand to his Deck and drawing 5 new cards . Featured Duels . Insector Haga VS Dark Yugi .
