ZEXAL " anime . It first aired in Japan on May 28 , 2012 , and in the United States on April 13 , 2013 . Summary . Mr . Heartland urges the crowd to congratulate Kite on his victory . He says that along with Vetrix , Kite has reached the semifinals . Their names are shown on the Duel Coaster Stadium screen and Heartland continues that there are only two slots left , while the other finalists are shown - Quattro , Yuma , Shark and Nistro . He wonders who will survive and says that he ' s sure Duel fans around the world are excited for the conclusion and tells them all to yell " Heart Burning ! " . Yuma is back on his Duel Coaster and yells that he ' ll go all the way to defeat Vetrix and Dr . Faker . He says he won ' t forgive them for using their children as tools of revenge . Astral says he feels a strong pulse coming from the left side - the same one given off by the crest s of Trey and Quinton . Yuma asks if that means Vetrix is there and Astral says that could be it and Yuma speeds off in that direction . Heartland displays the Duel Field , " Magma Field " , on the monitor and wonders who will arrive at that battlefield . Shark steps onto the field . Summer is excited , saying Shark is so cool . Cathy pops up in front of her and says she doesn ' t care if it ' s not Yuma Duel ing . Shark faces Quattro , saying he finally caught him and he won ' t let him escape this time . Quattro says that ' s bothersome and insists he didn ' t run away - he lured him here . He says that in this world of fire and heat , Shark will be at a disadvantage . Since Shark ' s Deck is full of WATER - Attribute monsters , he won ' t be able to survive here . Now Jen is excited , urging Quattro to give them his fanservice today . Bronk realizes they don ' t know of Quattro ' s true persona and Caswell says his true identity is that of a devil . The Duel begins , with Shark taking the first turn . Shark tells Quattro not to underestimate him and activate s " Plate Salvage " , which will negate the effect s of face - up Field Spell Card s until the end of Quattro ' s next turn . Ice covers the volcanoes and lava pools , with Shark smirking . Yuma , Tori and Astral arrive at the field ; Shark seems surprised to see Yuma , but Quattro does not . Tori asks if this is really the Magma Field and Yuma says its not hot at all . Yuma sneezes and Astral says that ' s expected of Shark - he must have negated the effects with a Spell Card . Vetrix appears in the form of what seems to be a hologram , saying its finally begun . He declares that its an important fight for both of them and urges them to fight their hardest as he watches . His crest ' s power radiates outward . Shark Normal Summon s " Tripod Fish " and announces that since he control s a face - up Fish - Type monster , he can Special Summon " Shark Stickers " from his hand via its own effect . Yuma says there are two Level 3 monsters and Astral says " Xyz Summon " . Shark overlays his monsters to Xyz Summon " Submersible Carrier Aero Shark " in Attack Position . He activates its effect , detach ing an Overlay Unit to inflict damage to Quattro equal to the number of cards in his hand times 400 . " Aero Shark " fires three missiles , which hit Quattro , knocking him onto his back and dropping his Life Points to 2800 . Yuma says Shark is so cool , inflicting effect damage on his first turn . Bronk and Caswell cheer and Shark Set s two cards , ending his turn . Quattro chuckles , saying they ' ve only just started and he ' s already Xyz Summoned . He compliments Shark , but says it gives him the urge to break him . As Shark controls an Xyz Monster and Quattro controls no monsters , he is able to Special Summon " Gimmick Puppet Magnet Doll " from his hand via its own effect . He Normal Summons " Gimmick Puppet Gear Changer " , explaining he can make it have the same Level as another " Gimmick Puppet " he controls . He says its time for a gear change and " Gear Changer " becomes Level 8 . Tori says that now Quattro has two monsters of the same Level as well . Yuma says he ' s coming and Quattro overlays his two monsters to Xyz Summon " " in Attack Position . Yuma says its appeared - the " Number " that devastated Bronk and Caswell . Quattro announces that if Shark is coming at him all the way , he must do the same . He says he ' ll give Shark the ultimate fanservice . Summer wonders what that monster is and Jen doesn ' t appear to know either . Suddenly , the feed is cut and Heartland wonders what happened . He says its unfortunate that complications occurred again in such an important Duel . However , this time he is being sincere and he wonders if it was " their " work . Vetrix appears at the field again , giggling and saying he felt that the rest of the Duel shouldn ' t be shown , so he broke the cameras . He tells Quattro to send Shark all the way into the darkness . Quattro activates the effect of " Giant Grinder " , destroying " Aero Shark " since it is an Xyz Monster . Its devoured by the hole in the chest of " Giant Grinder " . A cannon then emerges from the hole , firing , knocking Shark off his feet and dropping his Life Points to 2100 . ( cut from the dub is " Aero Shark " being absorbed and grinded by " Giant Grinder " . The cannon - like object of " Giant Grinder " is also made less realistic ) . Yuma yells Shark ' s name and Quattro declares a direct attack . " Giant Grinder " attacks with its whip , but Shark activates his face - down " Bubble Bringer " , negating the attack . Yuma says Shark is safe , but Quattro says it doesn ' t matter - the effects of " Magma Field " will return now , adding that it will be a scorching hell . He ends his turn and the volcanoes erupt , melting the ice . Yuma says its really hot and Tori says it really is a scorching hell . Shark tells Quattro to save the bravado for the when the Duel is over . He Normal Summons " Hammer Shark " and activates another effect of " Bubble Bringer " , send ing it to the Graveyard to Special Summon " Tripod Fish " from the Graveyard . The effect of " Tripod Fish " activates as it was Special Summoned , so its Level increases by 1 , to 4 . Quattro calls Shark an idiot , explaining that " Magma Field " will destroy all WATER - Attribute monsters when they are Summoned . He says Shark ' s monsters cannot live in this environment . Two " Solar Flare Dragon s " spring from the lava and jump at Shark ' s monsters , but an energy shield is suddenly erected in front of Shark . Quattro and Yuma are confused and Astral says its a Trap Card . Shark has activated a Continuous Trap , " Adapt to Adversity " . He explains that it prevents monsters from being destroyed by effects that activate upon their Summoning . He says that now his monsters can survive the scorching hell . Yuma cheers and Astral again says that ' s to be expected of Shark - you cannot underestimate him . Shark remembers falling into Quattro ' s trap at the National Duel Circuit and knows that Quattro hurt his sister , who had nothing to do with that match . He says he won ' t forgive him and no matter what , he will defeat him . Shark reveals that the monster Summoned with " Bubble Bringer " can be treated as two Overlay Units for an Xyz Summon . Shark overlays his now - three Level 4 monsters to Xyz Summon " " in Attack Position . Yuma remembers that card and Vetrix says that ' s right - its the card Trey gave to Shark , by Vetrix ' s command , that is . Vetrix says he was waiting for this moment , which would increase the darkness in Shark ' s heart . Quattro is shocked , saying that card was Trey ' s . Quattro says he knew Quinton and Vetrix were planning something , but he never imagined they ' d use Trey to give Shark a " Number " . Vetrix appears behind him and says there ' s a reason he didn ' t tell him . Quattro asks what that is and Vetrix responds that Quattro would have ruined the plan with his loose tongue . Vetrix ' s hologram begins to randomly teleport around and he says that everyone has their own role . Quinton had his and Trey had his . Quattro asks what his role is and Vetrix responds that it is to send Shark ' s heart into darkness . He adds that its gone according to plan so far and that Quattro has done well . Quattro didn ' t know all of it was part of Vetrix ' s plan and Vetrix says it should have been obvious . He adds that Quattro won ' t get away safely if he underestimates Shark but says he should know the powers of both Shark and " Shark Drake " well . Shark orders " Shark Drake " to attack " Giant Grinder " , who explodes as Quattro ' s Life Points drop to 1500 . Shark declares the effect of " Shark Drake " , detaching an Overlay Unit to Special Summon the destroyed " Giant Grinder " with 1000 less ATK . Tori asks why ' s he reviving his opponent ' s monster and Astral says that " Shark Drake " can now attack it again . Yuma realizes Quattro has only 1500 Life Points left , so Shark has won . " Giant Grinder " rises from the lava with 500 ATK , but Quattro says he won ' t let Shark do that . He activates the effect of the " Gimmick Puppet Twilight Joker " in his hand , banish ing " Giant Grinder " from his Graveyard to Special Summon itself . " Twilight Joker " appears and cuts the strings of " Giant Grinder " , who falls back into the lava . Vetrix says Shark made a strong move , but Quattro did counter it - with that Quattro can continue fighting and push Shark even more . Shark says he narrowly escaped and ends his turn . Vetrix says Quattro must fight harder - Shark is still alive and kicking . Quattro turns and yells that he knows that . No one but Quattro can see Vetrix , so they wonder what ' s going on . Quattro says he understands - his role is to push Shark into the darkness . In order to fulfill that , he had hurt his younger sister and set a trap at the Duel Circuit . He yells he did it all for Vetrix , by Vetrix ' s command . Tori asks what that means and Shark tells Vetrix to come out if he ' s here . He appears before Shark , who rushes at him , but the hologram just flickers and reappears elsewhere . Yuma asks if Vetrix is here and Astral says they must be able to see him through some strange power . Vetrix says that ' s correct and he expected that of Astral . Astral asks what Vetrix ' s end goal is - what is the point of all this ? Vetrix says there ' s no use in hiding it from anyone here . Three holograms of Vetrix appear , one each in front of Yuma , Tori and Astral . They say the reason that Shark must be pushed into darkness is for Vetrix to control him - as an assassin to defeat Dr . Faker . Shark says he has no reason to do anything like that , while Vetrix insists he ' ll have no choice - he will become his puppet . Quattro says he and his brothers fought hard for Vetrix - why were they not chosen ? He says he won ' t accept it and Vetrix again responds that everyone has their own role - and Shark fits the role of assassin better than Quattro . Enraged , Quattro says he will be the one to take down Faker . First , he will prove he ' s stronger than Shark . Quattro begins his turn , playing " Gimmick Puppet Ritual " . He explains it will Special Summon a " Gimmick Puppet " from his Graveyard , put it may not attack this turn . He tells " Magnet Doll " to return and overlays it with " Twilight Joker " to Xyz Summon " " in Attack Position . He equip s it with " String of Destiny " , which augments its sword . He explains that it sends the top card of his Deck to the Graveyard and if its a monster , " Gimmick Puppet of Strings " will be able to attack a number of times equal to that monster ' s Level , but the attacked monster will not be destroyed by battle . The card is " Gimmick Puppet Dreary Doll , so Quattro may now attack " Shark Drake " eight times . He orders his first attack with " Heaven ' s Blade " , dropping Shark to 1900 Life Points . Astral says that with " String of Destiny " , the damage will pile up quickly . Quattro tells " Gimmick Puppet of Strings " to make Shark suffer more and it attacks again . It attacks a third time , with Tori looking away in horror and Yuma telling Quattro to stop , insisting that this isn ' t Dueling . He says Dueling isn ' t for anger and revenge . Vetrix reappears in front of him , saying he won ' t allow him to interfere . His crest activates and Yuma is tied in chains , now unable to move . Vetrix says this is the climax and tells Yuma to watch quietly . Shark ' s Life Points are now 1300 . Tori yells for Quattro to stop and Yuma says that Dueling is to make people happy , not make them suffer . Quattro tells Shark to suffer more and then land in hell , ordering his sixth attack . Yuma continues to rant , saying that those who Duel become friends - it shouldn ' t be used to hurt people . Vetrix appears to Yuma again , saying he really is just like Kazuma . Vetrix says Kazuma always talked of Yuma , of bonds and of making people happy . He says it was Vetrix that involved Kazuma and Vetrix responds that the one who took Yuma ' s father from him is Dr . Faker . If Yuma must hate someone , it should be Faker . Vetrix continues that if that happens , darkness will be born from Yuma ' s heart and then spread . Vetrix says he did promise Yuma he would eat his heart next time . Yuma tells to shut up and says he won ' t forgive him for hurting Dextra like that and used his own sons for revenge . Vetrix says that ' s very good - darkness is being born in his heart from his anger . Vetrix urges Yuma to hate both him and Faker . He yells for Vetrix to shut up and Quattro declares his last attack , dropping Shark to 500 Life Points . Quattro continues that its not the end and activates the effect of " Gimmick Puppet of Strings " , detaching an Overlay Unit to place a String Counter on " Shark Drake " . It is ensnared in crimson strings , and Quattro says that at Shark ' s End Phase , " Shark Drake " will be destroyed and Shark will take damage equal to its ATK . Quattro ends his turn and Yuma yells to Shark , telling him to speak . Shark does not respond . Featured Duel : Shark vs . Quattro . This Duel takes place at a Duel Field , " Magma Field " .
