Yu - Gi - Oh ! ZEXAL - Episode 115 " Tentacles of Terror , Part 2 " , known as " Shark and IV ' s World - Shaking Mayhem ! ! Hell - Shark Tag Team " in the Japanese version , is the one hundredth and fifteenth episode of the " Yu - Gi - Oh ! ZEXAL " anime . It first aired in Japan on August 4 , 2013 and aired online on Hulu on July 21 , 2014 . Summary . Quattro is confused about how two new monsters split from the " " he just destroy ed . Yuma is confused as well , and Chironex explains the effect of " Stealth Kragen " . When it is destroyed , it Special Summon s a number of " Kragen Spawn " or " Stealth Kragen " from the Extra Deck or Graveyard equal to the number of Overlay Units that " Stealth Kragen " had , with one Overlay Unit each . Since " Stealth Kragen " had two Overlay Units , Chironex Special Summons two copies of " Kragen Spawn " in Attack Position . Chironex adds that " Kragen Spawn " shares the same effect as " Stealth Kragen " and continues that among some jellyfish , there is a high - ranking one capable of dividing in two , regenerating from the original . When a high class grows too old , they can become young again . Chironex tells Shark and Quattro not to be surprised ; jellyfish lack hearts or brains . Quattro calls Chironex not for boasting about not having a brain . Chironex is offended at the remark and repeats his question , " Who do you think you are ? ! " while calling Quattro a " little punk " ( Chironex lecturing Shark and Quattro about the jellyfish is cut from the dub ) . Quattro reminds himself about the devastating effects Chironex ' s monsters have ; if he does not deplete his opponent ' s LP fast enough , he will lose . Quattro activates the effect of " " , with his palm releasing a burst of energy . He detaches an Overlay Unit to destroy all other Xyz Monster s on the field and inflict their combined ATK as damage to their controllers . Quattro yells at Chironex to break apart as " Giant Grinder " pulls the " Kragen Spawn " into its chest cavity and grinds them up . He declares , " Destruction Cannon ! " and " Giant Grinder " fires a blast of crimson energy from its cannon at Chironex , reducing him to 2300 LP . Quattro is satisfied that he inflicted this much damage to Chironex . Trey congratulates his brother on a job well done . Chironex activates the effects of the two destroyed " Kragen Spawn " , Special Summoning " Stealth Kragen " from the Graveyard and a third " Kragen Spawn " from his Extra Deck . He boasts that he will fill the entire world with jellyfish ( in the dub , Chironex asks if his opponents like jellyfish ; they will be there until they are through ) . Quattro Set s a card and ends his turn . Trey says no matter how many times Quattro and Shark destroy Chironex ' s monsters , they will keep coming back . Yuma wonders what they will do next . Shark shakes from the poison ' s effects and thinks he cannot lose the Duel ; he must save Rio . At the hospital , Rio continues to suffer from the effects of the poison . While doctors check up on Rio , Tori stands outside of her room and contacts Yuma through her Duel Gazer . She informs Yuma that Rio ' s condition is worsening ; the doctors are saying there is nothing they can do and urges him and the others to cure Rio and Shark . Back at the Kastle ' s mansion , Yuma says this is bad ; Shark and Quattro are in trouble even before they finish the match . Upon seeing Shark continuing to suffer from the poison , Yuma calls Chironex out for a low tactic such as this and yells at him to fight fair and square . The aquatic Barian laughs in response ( this is cut from the dub ) . Quattro tells Shark that while he may be worn out , his sister is about to die ; this is something they cannot change and they must win ( in the dub , Quattro urges Shark to stay strong . Since Chironex will not give up , Shark must save being sick for another day ) . Shark replies that he does not need anyone to tell him that ; he is confident that he will not lose . Yuma mutters Shark ' s name . Shark mentally admits that Chironex is a formidable opponent ( in the dub , Shark still thinks he can talk tough ) , and there is no telling how long his body can hold out . Shark ' s vision starts to blur and he remembers that Chironex ' s monsters will keep coming back if they are destroyed . If Shark does not defeat Chironex fast enough , he will die from the poison . Suddenly , Shark remembers the " Number " he got from the undersea ruins , " " . If he Summons it , he may have a chance . Shark starts his turn , draw s " Skull Kraken " and Sets it . Quattro chides Shark for lacking his usual vigor ; he can attack Chironex this turn . Even if Chironex keeps on reviving his monsters , Quattro will smash him with his fist ( in the dub , Quattro advises Shark to go on the offensive when he still has the strength and to show Chironex what it takes to beat him ) . Chironex chuckles at the sight of Quattro and Shark bickering and calls it unsightly . He activates the Continuous Trap Card , " Receding Tide " . This allows Chironex to flip a monster Shark Set this turn into face - up Defense Position , while preventing any Flip effects from activating . He takes notice of the DARK Attribute of " Skull Kraken " and wonders if Shark gave up on the WATER Attribute because he is afraid of the effect of " Stealth Kragen " . Addressing Shark as " junior " , Chironex calls him simple - minded ( in the dub , Chironex calls Shark a " scaredy - shark " ) . Quattro reluctantly admits that Chironex is right and chides Shark for his strategy ( in the dub , Quattro expresses more concern for Shark ; he does not care about Shark ' s condition , since he must save Rio ) . Shark yells at Quattro to shut up and ends his turn . As the poison continues to take hold , Shark thinks he is losing his vision , but he must endure the poison until he gets a chance to defeat Chironex . Chironex disdainfully says Shark does not know when to die . After drawing , he states that he will put Shark out of his misery . He activates " Jelly Rain " , which lets him change the Attributes of all monsters currently on the field to WATER . It starts to rain , changing the Attributes of " Giant Grinder " and " Skull Kraken " from DARK to WATER . Chironex chuckles and says he will finish both Shark and Quattro off , starting with Quattro . He activates the effect of " Stealth Kragen " and targets " Giant Grinder " . " Stealth Kragen " stabs " Giant Grinder " on the chest with its tentacles and destroys it , while inflicting 1500 damage to Quattro . " Stealth Kragen " then fires a beam from its core at Quattro , reducing him to 500 LP . Chironex goes for Shark next , this time using the effect of " Kragen Spawn " to destroy " Skull Kraken " and inflict its 600 ATK as damage . Trey says this isn ' t good ; Shark only has 400 LP left . Yuma exclaims that Shark will lose if the effect goes through . " Kragen Spawn " extends its tentacles to destroy Shark ' s monster , but Quattro musters enough strength to activate his face - down " Shade of Strings " . This prevents " Skull Kraken " from being destroyed by card effects this turn . Red strings bind the tentacles of " Kragen Spawn " together and destroy them . Shark is surprised that Quattro saved him . A frustrated Chironex decides to attack Shark instead ( in the dub , Chironex says Quattro is delaying the inevitable ; his opponents will go down anyway ) . He commands " Stealth Kragen " to attack " Skull Kraken " with " Tentacle Surge " . " Stealth Kragen " glows purple , then attacks " Skull Kraken " with devastating whips from its tentacles , destroying it . Quattro says this isn ' t good ; Shark ' s field is empty . Chironex orders " Kragen Spawn " to attack directly . " Kragen Spawn " charges at Shark , while Quattro yells his name . Shark activates his Set " Deep Current " to negate the attack and end the Battle Phase ; a tornado of water blocks the attack . Disappointed , Chironex calls Shark persistent , Sets two cards and ends his turn . Shark feels a surge of pain and falls on his back . Quattro and Yuma yells his name . Back at the hospital , Rio is in the same predicament . Tori informs Yuma that Rio ' s condition is getting even worse ; there is no time . After hearing the message , Yuma encourages Shark to save his sister . However , Shark continues to lay on his back , thinking his body will not listen to him . He doubts that he can save Rio now . Quattro calls Shark pathetic and yells at Chironex that he will get a better taste of his " fanservice " this time . He begins his turn and activates " Puppet Ritual " , since he has less than 2000 LP . He Special Summons " Giant Grinder " . Red strings descend from the sky and pull " Giant Grinder " out of a Graveyard portal . Chironex says " Giant Grinder " is not strong enough to defeat any of his monsters . Quattro tells him not to get ahead of himself and Tribute s " Giant Grinder " to Special Summon " Gimmick Puppet Nightmare " . He adds that if " Nightmare " was Summoned this way , it can be treated as two Overlay Units for an Xyz Summon ( the actual monster is cut from the dub ) . Trey cheers Quattro on , while Shark mutters , " Quattro . . . " Quattro overlays his " Nightmare " to Xyz Summon " " . Trey exclaims that Quattro can win the Duel with its effect . Chironex disagrees and activates his Set " Jelly Bind " , as he controls a WATER monster . It prevents " Strings " from attacking or using its effects . Tentacles splash out from beneath " Strings " and bind it . Chironex proceeds to call " Strings " a truly useless puppet . Discontented with the current situation , Quattro Sets a card and ends his turn . Chironex reminds Shark that it is his turn , then asks him what ' s wrong and laughs . He remembers that his poison has now taken full effect on Shark ' s body ; Shark may not be able to stand up . Shark struggles to rise , but falls down again . Quattro yells Shark ' s name . Chironex laughs triumphantly ; the jellyfish has beaten the shark . Quattro berates Shark for his current state ; he isn ' t even a man . He calls him a useless brother for not being able to save his sister and orders him to get up harshly . Yuma is disgusted by Quattro ' s attitude ; how can Quattro say how he knows how Shark feels about Rio ? Quattro replies that he ' s aware of that . He understands now , since he is Shark ' s number 1 fan . He was the one who opposed Shark and hurt Rio . Because of that , he had to carry the scar on his face for the rest of his life . Shark fights caring more about his sister than about himself . Quattro also thanks Yuma and Astral for intervening ; because of that , he was able to get his family back together ( Quattro does not mention his family in the dub ) . He yells at Shark to rise again because he fought for his family all this time . The real Shark would never give up on his sister . Quattro screams at Shark to stand up for a third time . Shark finally gathers enough strength to get up , to the relief of his friends . He calls Quattro a nosy person . Chironex cries , " Impossible ! " in disbelief ( " You ' re getting up ? ! " in the dub ) . Shark says he is not ready to lie around just yet ; Chironex curses at Shark . Quattro says if this is the case , he and Shark must finish the Duel so Shark can take a nap . Shark replies that he will take up the offer and mentally promises to save Rio . Shark finally begins his turn and draws " Big Jaws " . He activates " Sea Lord ' s Amulet " , which prevents WATER monsters he controls from being targeted by card effects this turn . Shark says a shark never lets its prey escape once it ' s caught until it chews it . He then activates " Edict of Atlantis " , which lets Shark increase the Levels of any WATER monsters he Summoned this turn by 2 . Since he activated a Normal Spell Card , Shark Special Summons " Big Jaws " from his hand in Attack Position . He increases its Level by 2 , to 5 , using the effect of " Edict of Atlantis " . Shark follows up by Normal Summon ing " Panther Shark " without Tributing , as Chironex controls two or more monsters . Yuma exclaims that Shark has two Level 5 monsters , while Quattro is pleased that the old Shark is back . Shark overlays his two Level 5 monsters to Xyz Summon " Number 73 : Abyss Splash " . Chironex trembles at the sight of Shark ' s newly Summoned monster . Shark reiterates the monster ' s name and recounts that he received the card from the underwater ruins . It contains his memories , but Shark quickly brushes the thought off and declares his name ( Shark does not tell Chironex this story in the dub ) . He vows to save Rio as she sheds a tear back at the hospital . Shark turns to Quattro and affirms his vow to win . Quattro agrees . Chironex is disgusted seeing his opponents , juniors , getting so excited . He activates his Set " Jelly Hole " , as a WATER Xyz Monster was Special Summoned . It negates the effects of all face - up cards his opponents control this turn . Tentacles bind " Abyss Splash " and " Edict of Atlantis " , negating their effects . Chironex activates the effect of " Stealth Kragen " to destroy " Abyss Splash " . Shark counters by activating the Quick - Play Spell Card , " Cascade Barrier " to protect " Abyss Splash " from being destroyed by card effects once . A waterfall appears in front of " Abyss Splash " and blocks the tentacles launched by " Stealth Kragen " . Shark continues that the ATK of " Abyss Splash " will be reduced to 0 this turn . Chironex activates the effect of " Kragen Spawn " to destroy " Abyss Splash " . He says that while Shark will take no damage , he will lose the only monster he has . The tentacles of " Kragen Spawn " stab " Abyss Splash " on the chest and destroy it . Shark and Quattro smile at each other . The latter activates his Set " Celestial Strings " , since he controls a " Gimmick Puppet " Xyz Monster . This lets him Special Summon an Xyz Monster from the Graveyard . " Gimmick Puppet of Strings " breaks free of its bindings , launches strings from its hand and pulls " Abyss Splash " out of a Graveyard portal . Trey and Yuma comment that Quattro and Shark are amazing . Quattro adds that " Celestial Strings " will attach " Gimmick Puppet of Strings " and its Overlay Unit to " Abyss Splash " ( in the dub , no mention of " Celestial Strings " itself becoming an Overlay Unit is made , though it still does become one ) . Shark activates the effect of " Abyss Splash " twice , detaching an Overlay Unit to double its ATK for each Overlay Unit detached until the End Phase . Chironex exclaims that " Abyss Splash " has 9600 ATK . Shark and Quattro command " Abyss Splash " to attack " Stealth Kragen " with " Final Fall " . " Abyss Splash " releases a wave of purple energy from its trident at " Stealth Kragen " , destroying it and knocking Chironex back . As his LP hit 0 , he reverts to his human form . Chironex ' s " Number " card appears and floats to Quattro , who takes it . He glances to Shark , who has shaken off the poison . At a hospital , a nurse reports that Rio ' s heart rate and blood pressure have returned to normal . A doctor says he cannot believe how the poison was counteracted . Tori brings the good news to Yuma , who nods in agreement and tells Shark that Rio is fine . Quattro says that Shark made him work hard during the Duel , but he got sloppy ( in the dub , Quattro tells Shark that Rio should be grateful for whoever saved her . He also tells Shark that he hoped that he took notes on how a Duel should be played ) . Shark is upset at Quattro for butting in without permission . Quattro responds that this is the same old Shark ; he is not charming and will not die . Trey wonders if the two are on good terms ( in the dub , Trey tells Yuma that Shark and Quattro argue more often than him and Astral ) . He turns to Yuma , who is saddened that Astral is not here . He recalls some of the times when Astral stood by his side and encouraged him during their Duels . Trey is worried over Yuma . Chironex rises and curses to himself that he lost to Shark . When Shark gives him a cold stare , Chironex gasps in surprise . Years ago , Chironex was being chased by the police after messing up a crime . Upon seeing a fleet of police cars up ahead , he panicked , drove off the bridge and landed on the one below it . Chironex remembers that Shark was in the car he crashed into . He mutters that Shark cannot be the same kid who died in the accident ; if Shark really died , he wouldn ' t be standing in front of him right now . Shark asks what Chironex means . Chironex says he remembers the name " Reginald Kastle " now . After the accident , he learned that the entire Kastle family was killed and Shark should be dead ( Chironex does not mention the Kastle family ' s deaths in the dub ) . Shark yells at Chironex to stop screwing around . The Barian falls to his knees , in utter disbelief that Shark is still alive before disappearing . Shark yells at Chironex to wait , but the Barian is gone before he can reach him . Shark wonders what Chironex really meant . He notices the fountain in front of him and tears off some of the vines covering it . Shark is shocked to see a familiar emblem in front of him . That emblem was the coat of arms he saw in his past life . Quattro asks Shark what ' s wrong . Shark thinks that the king ' s emblem and his family ' s emblem are the same . Yuma and Trey wonder what ' s wrong with Shark as well and Shark falls to his knees , thinking he could be a Barian . Featured Duel : Chironex vs . Shark and Quattro .
