Yu - Gi - Oh ! - Episode 010 " Give up the Ghost " , known as " Blue - Eyes White Dragon ' s Counterattack " in the Japanese version , is the tenth episode of the " Yu - Gi - Oh ! " second series anime . It first aired in Japan on June 20 , 2000 and in the United States on December 1 , 2001 . Summary . Yugi manages to destroy Ghost Kaiba ' s " Blue - Eyes White Dragon " . Ghost Kaiba promptly plays another " Blue - Eyes White Dragon " . He laughs , reminding Yugi that there are only three " Blue - Eyes White Dragon " cards in existence and they ' re all in his Deck . Yugi ' s Grandpa had the fourth , but Ghost Kaiba says that he ripped it up . Ghost Kaiba claims his knowledge of this event proves his identity as Kaiba . He relates the events of that match , claiming that without " Exodia " , Yugi can ' t win . Meanwhile , the real Kaiba is still in his secret underground computer room . His computer tells him it ' s rerouting the data from Arena 146 so they can confirm whether Yugi is dueling there , though Kaiba is already sure he is . The computer finds Yugi at the arena and points out Yugi ' s opponent : " Seto Kaiba . " Kaiba can ' t believe it , but the computer assures him it ' s true , and the opponent is using Kaiba ' s Deck . Kaiba realizes that Pegasus must have taken his Deck when he escaped . The computer goes on to tell him that the duelists are tied , but the impostor has his second " Blue - Eyes White Dragon " on the field , after Yugi destroyed the first one with " Dark Magician " and " Spellbinding Circle " . Yugi currently has no cards in play , and it ' s his move . Kaiba echoes his impostor ' s claim , that without " Exodia " , Yugi can ' t win against the " Blue - Eyes White Dragons " . He has no other cards in his Deck strong enough to stand up against " Blue - Eyes White Dragon " , let alone two of them . Yugi will lose on his next turn unless Kaiba can decrease the " Blue - Eyes ' s " power from there ( in the original Japanese version , Kaiba is astonished that Yugi managed to destroy even one of the " Blue - Eyes White Dragons " without " Exodia " , but nonetheless recognizes Yugi ' s current dilemma ) . He plans to upload a virus into the arena ' s holocomputer to weaken the Blue - Eyes . The computer suggests they wait to see Yugi ' s next move , but Kaiba says they can ' t afford to risk Yugi losing the Duel , and orders the viral injection upload . Back at the arena , Yugi realizes he doesn ' t have any monsters that can stand up to the Blue - Eyes White Dragon and that he might lose . Ghost Kaiba tells him this Duel is over . He still has " Defense Paralysis " active , so whatever monster Yugi plays won ' t be able to defend itself . Yugi plays " Feral Imp " in Attack Position . The real Kaiba , watching the Duel on screen , wishes Yugi had waited a few more seconds before making his move . He asks the computer if it can ' t get that virus uploaded any faster . The computer tells him they ' re already halfway there and that its current speed is as fast as it goes . The viral implant is sixty percent completed , but it doesn ' t seem to be working , the " Blue - Eyes White Dragon ' s " ATK is still at 3000 . Kaiba worries that something is wrong . Ghost Kaiba orders the " Blue - Eyes White Dragon " to attack , but the dragon doesn ' t move . The virus has finally started to take effect . Kaiba watches the ATK of " Blue - Eyes White Dragon " drain away , down to 2900 , then to 2800 , but it ' s still too strong . It has to get weaker , or it will still beat Yugi . Yugi and Ghost Kaiba also watch the " Blue - Eyes ' s " ATK go down , wondering what ' s going on . The dragon begins to melt , its hologram breaking up . Kemo contacts Pegasus on his radio to tell him about the problem . ( In the Japanese version , Saruwatari just wonders what ' s going on . ) Pegasus is in his dining hall , watching the duel on the computer screen . Croquet asks how Yugi did that , but Pegasus says it wasn ' t Yugi , it was Seto Kaiba . " It seems , " he says , " that the real Seto Kaiba is still very much alive . " Kaiba tells his computer to get ready to implant the virus on the third " Blue - Eyes " , but just then , his screen starts to break up . The computer says they ' ve been locked out by a remote terminal . A cartoon rabbit appears on the screen , saying , " Hey , Kaiba . " Kaiba realizes it ' s Pegasus . Back at Pegasus ' s castle , Pegasus chuckles and drinks from his glass , while his goons move in on Kaiba ' s mansion , breaking in the front door . The " Blue - Eyes White Dragon ' s " attack strength holds at 2000 . Kaiba protests that this should have worked , as the computer tells him that it ' s launching its attack . Ghost Kaiba tells his dragon it ' s time to obliterate them , and the gang all watch in horror . Kaiba , unwilling to let Yugi lose to an imposter of him , calls out Yugi ' s name , and Yugi hears him . The attack stops , and the dragon disintegrates . The " Blue - Eyes " has heard its real master ' s call , and destroyed itself . Kaiba ' s computer tells him that the dragon is destroyed , but the virus wasn ' t responsible . " Then how ? " Kaiba asks . " Did Yugi somehow do this ? The computer asks , " How could he ? It ' s your Deck . " Then Kaiba says , " It ' s the Heart of the Cards . Yugi was right . " Then he notices his door lock being activated . Pegasus ' s henchmen are about to break in . Ghost Kaiba panics . Yugi tells him that Kaiba ' s still alive and he stopped the impostor . Ghost Kaiba continues to insist that he ' s Kaiba , while Mokuba celebrates that his brother is alive . Téa asks what ' s going on , and Mokuba explains that the last time they Dueled , Yugi showed his brother the Heart of the Cards . He explains that the impostor may have taken his Deck , but the real Seto Kaiba is alive and well . ( In the Japanese , Mokuba says that his brother is the only one who can stop the Blue - Eyes White Dragon . That was his brother . His brother isn ' t dead . ) Yugi tells Ghost Kaiba that the real Seto Kaiba destroyed that monster . Yugi knows because he sensed Kaiba calling out to him when it happened . ( Japanese , Yugi says it proves that Kaiba is alive . Now he can concentrate on the Duel . Then he tells the Ghost that he should reveal himself . Yugi doesn ' t want to continue dueling with him as he is . ) Ghost Kaiba reveals his true form ( Ghost Kaiba was known as Mimic of Doom in the English anime and is called the Death Imitator in the Japanese version ) , as a monstrous clown , and tells them he is the evil part of Kaiba that was banished to the Shadow Realm by Yugi , brought back by Pegasus ( in the Japanese version , the Death Imitator says he prefers looking like this . He was sent by Industrial Illusions to take on the identity of a dead person . Then he asks Yugi to Duel with him . The flashback of Yugi Mind Crushing Kaiba from their first Duel is added in the dub ) . Pegasus ' s henchmen storm into Kaiba ' s computer room , but Kaiba already left ( their guns are removed from the dub ) . Croquet orders them to search the grounds , while Pegasus , looking on from his castle , muses that this is one twist even he didn ' t foresee ( in the Japanese version , Pegasus says he can ' t believe the " Blue - Eyes White Dragon " would be dismissed . Good for Yugi , luck is part of his ability ) . Croquet then reports the bad news to Pegasus that they ' ve lost the real Kaiba again , and Pegasus mutters that that ' s two escapes , must he lock Croquet away ? Again ? ( Japanese Pegasus , however , is pretty blasé about the whole thing , just saying , " No problem , " and that they should just watch the rest of the Duel . ) He tells Croquet to get Kemo on the radio . Mokuba taunts the clown , telling him he ' d better start worrying about what his brother ' s going to do to him when he catches up with him . ( Japanese , Mokuba tells the clown that those cards are his brother ' s , and no one else can use them . ) Kemo gets a message from Pegasus telling him that Kaiba ' s gotten away , and not to lose the little one , no matter what . ( Japanese , Kemo doesn ' t get any message . He thinks , Yugi survived that obstacle , but Kaiba still has one more Blue - Eyes White Dragon . ) Yugi says to the impostor , " I don ' t know what to call you now . I was thinking of ' monster ' , but I don ' t want to insult the cards . " Then he tells his opponent it ' s his move . He ' s got a whole Deck to go through , and only one " Blue - Eyes " left . ( Japanese , Yugi tells the clown he hasn ' t got any monsters on the field . Go ahead and summon one . The clown thinks he still has another Blue - Eyes . Yugi won ' t get another miracle . ) They continue to Duel ( in the Japanese , the Imitator suddenly appears as Pegasus , telling Yugi he ' s going to get it now ) . The impostor tells Yugi it will soon be all over . Yugi ' s friends taunt the impostor . Finally , the impostor draws the third Blue - Eyes White Dragon . Mokuba assures Yugi that Kaiba will help him again , but Kemo knows Kaiba ' s no longer at his computer , pointing out that Blue - Eyes has its full 3000 ATK . He says they found Kaiba ' s hiding place and caused him to run , eliminating the possibility of more outside help . Yugi plays " Reborn the Monster " on " Blue - Eyes White Dragon " . The Mimic says that won ' t do Yugi any good , the two Blue - Eyes are evenly matched . But Yugi says their powers are not the same . He still has " Mystical Elf " on the field , chanting a spell that allows her to transfer her ATK to any monster he chooses . Yugi says this move was inspired by Seto Kaiba himself , who showed him that you can alter the power of a " Blue - Eyes White Dragon " . But he ' s raising his to 4100 rather than lowering it , as Kaiba did to the impostor ' s . " Consider this a message from the real Seto Kaiba , " Yugi says . " You lose ! " Yugi ' s " Blue - Eyes " destroys the Ghost ' s " Blue - Eyes " , winning the Duel . Then Yugi uses his Mind Crush on the Ghost , sending it back to the Shadow Realm . Yugi issues a warning to Pegasus , who he knows is watching . " Nothing will stop me , " he says . " I ' m coming for you , Pegasus ! " Pegasus ' s wine glass shatters in his hand . Pegasus chuckles grimly , saying that Yugi has developed his Shadow powers quite a bit in such a short time , but when they finally Duel , Yugi ' s Millennium Puzzle will be his . Yugi retrieves Kaiba ' s Deck from the impostor ' s side of the arena . They notice Mokuba is missing , wondering where he is . Kemo left with him . Featured Duel : Yami Yugi vs .
