ZEXAL " anime . It first aired in Japan on December 5 , 2011 and in the United States on October 20 , 2012 . Summary . Shark confronts Quattro , saying that he finally found him . Quattro responds that he forgot Shark really is the biggest fan he has . Shark asks to repay the debt he owes Quattro . Quattro asks how Shark ' s " precious " sister is doing . Yuma looks perplexed as he didn ' t know Shark has a younger sister . Shark thinks back to the National Duel Circuit , when Quattro set Shark up to see his Deck in the waiting room , leading to his disqualification . Shark blames himself for not being able to help his sister . Shark says he ' ll exact his revenge here and now and Yuma seems worried that Shark would Duel for revenge . Quattro agrees , responding that he really likes people like Shark . Before either can act , Trey deploys a Duel Anchor , snaring Shark ' s wrist . Trey explains that Shark won ' t be able to escape without finishing a Duel with Trey . Quattro tells Trey that Shark is his prey and to get lost . Trey says that Shark ' s Deck has no " Number s " , so there is no reason for Quattro to Duel him . He adds that Vetrix ' s orders are absolute . Quattro sighs and says that his " fanservice " is over . Quattro begins to walk off and Shark tells him to wait , asking if he ' s running away . Quattro shows a full Heart Piece , saying he ' s already done collecting them as his crest glows . He tells Shark he ' ll wait for him in the finals and vanishes in a swirl of dust , cackling . Shark screams Quattro ' s name and Trey tells him to calm down , saying his brother is quite busy and they have their own Duel to conduct now . Astral wonders just who these people are , thinking that that Duel Anchor is just like the one Kite uses . He speculates that these people are collecting " Numbers " using the same technical powers as Kite . Bronk and Tori help Caswell to his feet . They tell Yuma they ' ll take him to the hospital and urge him to stay and watch the Duel . Yuma begins to object , but Astral says he agrees . Shark arms his D - Pad , saying he ' ll crush Trey first just as he wishes . Trey says " Duel Mode , Change ! " and a gauntlet appears on his left arm . He throws a device out , which spins back at him and lands on the gauntlet in a wing - like formation - his D - Pad . Shark arms his D - Gazer and an orange D - Gazer tattoo appears around Trey ' s left eye . The two yell " Duel ! " and Trey says he ' ll go first . Trey activate s a Field Spell Card - " Sunken Kingdom " . A field of underwater ruins is manifested , complete with fish swimming through it as Trey explains that all WATER monster s will gain 300 ATK . Yuma takes a huge breath and believes he ' s drowning , asking where his oxygen tank is . Astral reminds him that this is Augmented Reality . Trey Normal Summon s " Chronomaly Mayan Machine " , Set s a card and ends his turn ( the Japanese name of the " Chronomaly " archetype is " OOPArts " ) . Yuma asks what are and Astral explains that they are works made by ancient civilizations who shouldn ' t have had the technology necessary to build them . He says their existence is still wrapped in mystery as images of " Crystal Skull " , " Cabrera Stone " , " Stonehenge " and " Ashoka Pillar " float by . Shark begins his turn , Normal Summoning " Hammer Shark " , whose ATK increases to 2000 due to " Sunken Kingdom " . Shark muses that Trey must not have been aware that Shark plays a Water Deck . Trey explains that " Sunken Kingdom " has an additional effect - " Chronomaly " monsters cannot be attack ed by Level 4 or lower monsters . Shark asks if that ' s his insurance and activates " Falling Current " , decreasing the Level of " Hammer Shark " to 3 . Trey says that Shark Duels strangely and asks what he ' s planning by lowering its Level . Shark Special Summon s " Big Jaws " from his hand in Attack Position via its own effect as he activated a Normal Spell Card this turn . Its ATK increases to 2100 via " Sunken Kingdom " . Trey says there are two Level 3 monsters . Shark overlays them to Xyz Summon " Black Ray Lancer " in Attack Position . Shark explains that Xyz Monster s have no Levels , so " Black Ray Lancer " can attack . Yuma complements Shark and " Black Ray Lancer " attacks and destroy s " Mayan Machine " with " Black Spear " , dropping Trey to 3400 LP . Trey activates his face - down " Stonehenge Methods " , causing to rise from the sea . He explains that when a " Chronomaly " monster is destroyed , he can Special Summon a Level 4 or lower Rock - Type " Chronomaly " monster from his Deck in Defense Position . He Special Summons " Chronomaly Colossal Head " . Shark Sets a card to end his turn . Trey draws and Normal Summons " Chronomaly Golden Jet " . He activates the " Orichalcum Chain " Continuous Spell Card . He explains that when this card is face - up when he performs and Xyz Summon , he can use one less Overlay Unit than usually required . Shark is shocked and Trey comments that the card has risks too - should " Orichalcum Chain " be destroyed , control of the Summoned Xyz Monster will shift to Shark . Shark is surprised he ' d take such a risk in order to Xyz Summon . Trey overlays his two Level 4 monsters , using one less Overlay Unit via " Orichalcum Chain " to Xyz Summon " " in Attack Position . Yuma says " Numbers " and Astral says that it is indeed . The ATK of " Shark Drake " rises to 3100 via the effect of " Sunken Kingdom " . " Shark Drake " attacks and destroys " Black Ray Lancer " with " Depth Bite " , dropping Shark to 3000 LP . Trey activates the effect of " Shark Drake " detach ing an Overlay Unit to to Special Summon the destroyed monster back to Shark ' s field in Attack Position , with its ATK decreased by 1000 . " Black Ray Lancer " appears with 1100 ATK . He explains that " Shark Drake " can then attack it again , and Yuma is surprised to see a " Number " that can do that . Astral says its more than just " attack twice " and calls it a very overpowered effect . Trey says " Shark Drake " will bite until its target has no bones left . " Shark Drake " attacks and destroys " Black Ray Lancer " again , reducing Shark to 1000 LP . Shark is thrown through the air by the attack , landing on his back . Yuma yells to him , asking if he ' s alright . Shark tells Yuma to shut up and asks if he honestly thinks he ' ll be defeated like this . Trey Sets a card and tells Shark that if he can ' t find a way to counter " Shark Drake " , he won ' t escape . Yuma says he ' s right and Astral states that there is a way to bring about a reversal in these circumstances . Shark mutters that he needs to take that " Number " from Trey . Shark begins his turn , Normal Summoning " Skull Kraken " , who bursts from the ground . Its effect activates , letting him destroy one face - up Spell or Trap Card . Black ink flows from the mouth of " Skull Kraken " , obliterating " Orichalcum Chain " . " Shark Drake " roars and moves to Shark ' s side of the field . Trey smirks , thinking its going as planned . That ' s the only thing Shark could do to survive . A purple aura appears around Shark as the " Number " begins to exert its influence over him and 32 appears on his hand . In his mind ' s eye , Shark faces " Shark Drake " , who tells him to accept him . It plunges one of its talons through Shark ' s chest and he screams in pain ( In the dub , Shark Drake just pokes him on the chest ) . The " Number " instructs him to accept it and release the darkness inside his heart . Shark remembers the times that Yuma reached out to him and when he expressed that there is nothing wrong with having a fear of losing . Shark yells that he ' s not the same as he used to be and the talon vanishes from his chest ( the wound left by the talon is changed from blood - red to light green in the dub ) . He tells " Shark Drake " he ' ll never be controlled by the likes of it . " Shark Drake " roars and vanishes from his mind . Back at the Duel , " Shark Drake " remains on his field . Shark yells that he is who he is and Astral says that Shark managed to suppress the power of the " Number " . Yuma is excited and Trey appears pleased that Shark wasn ' t possessed . " Shark Drake " attacks Trey directly , with Yuma saying he ' ll hit for massive damage if he connects . Trey says he won ' t let that happen and activates his face - down " Antikythira Gear " . He explains that it can be activated when his opponent controls two or more monsters and attacks directly . Trey can take control of one of the opponent ' s monsters , switch it to Defense Position and make it the new attack target . The gears rush towards " Skull Kraken " , but Shark activates his face - down " Extreme Pressure Power " , send ing " Skull Kraken " to the Graveyard and drawing a card . " Antikythira Gear " cannot take control of the monster that is attacking , so it resolve s with no effect as Shark says his trap is useless . The attack continues and Trey is reduced to 300 LP and thrown onto his back . Shark Sets two cards . Trey rises to his feet and complements Shark while thinking that his mission was to give Shark the " Number " . He thinks back , remembering that Vetrix told him he could lose purposely once the mission was accomplished . He urges Shark not to get overconfident and draws . He activates " Chronomaly Technology " , banish ing the " Mayan Machine " in his Graveyard to draw two cards and send the " Chronomaly Crystal Skull " in his hand to the Graveyard . He Special Summons " Chronomaly Crystal Bones " in Attack Position via its own effect as he controls no monsters while Shark does . Its effect activates , Special Summoning the " Chronomaly Crystal Skull " from his Graveyard in Attack Position . Trey overlays his two Level 3 monsters to Xyz Summon " Chronomaly Crystal Chrononaut " in Attack Position . Trey explains that by detaching an Overlay Unit , " Crystal Chrononaut " cannot be destroyed by battle this turn and any Battle Damage from battles involving it will be inflicted to his opponent . Trey smirks , saying the difference in ATK between " Shark Drake " and " Crystal Chrononaut " is 1000 - exactly the amount of LP Shark has left . " Crystal Chrononaut " attacks " Shark Drake " with " Reflect Flash " . Yuma is worried and Trey tells Shark that ' s it over . Shark activates his face - down " Plate Salvage " , causing the ruins of " Sunken City " to start floating upwards . He explains that it will negate the effect of Field Spell Cards for two cards . Now they are in the ruins , but on land . Yuma thinks its awesome that they ' re above sea level again . Since the effects of " Sunken Kingdom " are negated , the ATK of " Shark Drake " returns to 2800 and the attack continues , letting Shark survive with 300 LP . Astral thinks that was an amazing play . Yuma says they both only have 300 LP left and Astral muses that the next blow will decide the outcome . Trey is shocked that Shark survived " Reflect Flash " , but determines that he will use the effect of " Shark Drake " during his next turn - and that is when the Duel will be decided . Trey Sets a card and ends his turn . Shark immediately declares an attack with " Shark Drake " . Yuma says its Shark ' s win and Trey tells them not yet . He activates the effect of the " Colossal Head " in his Graveyard , banishing it to change " Crystal Chrononaut " to Defense Position . " Crystal Chrononaut " is destroyed . Yuma says that ' s not good - no damage was inflicted . Astral tells him no and Shark activates the effect of " Shark Drake " , detaching an Overlay Unit to Special Summon " Crystal Chrononaut " back to Trey ' s field with 1100 ATK . Shark asks if Trey thought he would forget the effect of " Shark Drake " . Shark attacks with " Shark Drake " again and Trey tells him that fortunately , he hasn ' t underestimated Shark at all . He says he knew Shark would be able to control the " Number " and activates his face - down " Chronomaly Ley Line Power " , switching the ATK of the battling monsters . Trey says he wins and Shark smirks , saying he expected that . He claims he ' s the fortunate one - he didn ' t ' underestimate Trey either . Shark says he knew that Trey would expect him to use the effect of " Shark Drake " . He activates his face - down " Sea King ' s Verdict " , negating " Chronomaly Ley Line Power " as it was activated during the Battle Phase . Trey asks how that could be and curses . Shark tells " Shark Drake " to resume its attack . " Crystal Chrononaut " is destroyed and Trey ' s LP fall to 0 . The Field Spell fades and Yuma is happy that Shark won . Astral calls the Duel a breathtaking display of offense and defense . Trey says he understands that Shark is quite good and that he lost - for today , at least . He tosses Shark a Heart Piece and holds up a full container of his own . He says it won ' t be easy for Shark if they meet again in the finals . Yuma is surprised Trey has already qualified too . Trey tells Shark to keep the " Number " and consider it a reward for winning the Duel . Trey ' s crest glows and he vanishes in a green light . Yuma ' s D - Gazer rings and he answers . Its Tori , who tells him they ' re at the hospital now and Caswell is holding up fine . Yuma says he ' ll be right over and then hears the engine of Shark ' s motorcycle roar . Shark tells Yuma not to get involved with him anymore and rides off . Yuma is worried about Shark Dueling for revenge . Astral observes that Yuma and Shark will Duel again eventually , since Shark has another " Number " now . At Vetrix ' s headquarters , Trey approaches Vetrix , who tells him he did a good job . He complements him , saying he always completes the tasks Vetrix assigns . Trey says he just does everything he can for Vetrix and Vetrix comments that modesty is one of Trey ' s virtues as well . Trey informs him that Shark wasn ' t possessed by the " Number " . Vetrix says that ' s not the case - the darkness that sleeps in a person ' s heart can come out as long as there is even the tiniest opening . It will slowly expand with their realization .
