"Shark Bait", known as "Determined Revenge - Tragic Duelist, Shark" in the Japanese version, is the thirty-fourth episode of the Yu-Gi-Oh! ZEXAL anime. It first aired in Japan on December 5, 2011 and in the United States on October 20, 2012.
Shark is determined to have his revenge on Quattro, but Quattro's younger brother Trey snares Shark with a Duel Anchor and allows Quattro to leave. Trey's mission from Vetrix and Quinton is to give a "Number" to Shark, which he accomplishes. Shark is able to resist completely being controlled by the "Number" and defeats Trey.
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 "Numbers", 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 activates a Field Spell Card - "Sunken Kingdom". A field of underwater ruins is manifested, complete with fish swimming through it as Trey explains that all WATERmonsters 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 Summons "Chronomaly Mayan Machine", Sets a card and ends his turn (the Japanese name of the "Chronomaly" archetype is "OOPArts"). Yuma asks what Chronomaly 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 attacked 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 Summons "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 Monsters have no Levels, so "Black Ray Lancer" can attack. Yuma complements Shark and "Black Ray Lancer" attacks and destroys "Mayan Machine" with "Black Spear", dropping Trey to 3400 LP. Trey activates his face-down "Stonehenge Methods", causing Stonehenge 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 "Number 32: Shark Drake" 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" detaching 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", sending "Skull Kraken" to the Graveyard and drawing a card. "Antikythira Gear" cannot take control of the monster that is attacking, so it resolves 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", banishing 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.
Trey draws and Normal Summons "Chronomaly Golden Jet" (1300/1400). He then activates the Continuous Spell Card, "Orichalcum Chain". The next time he Xyz Summons, he may use one less Overlay Unit. However, if "Orichalcum Chain" is destroyed, Shark will gain control of the Xyz Monster. Trey overlays his two Level 4 monsters treated as three to Xyz Summon "Number 32: Shark Drake" (2800 → 3100/2100) in Attack Position. "Shark Drake" attacks and destroys "Black Ray Lancer" (Shark 4000 → 3000). As it destroyed a monster by battle, Trey activates the effect of "Shark Drake", detaching an Overlay Unit ("Shark Drake" ORU 2 → 1) to Special Summon the destroyed monster from his opponent's Graveyard in Attack Position with its ATK reduced by 1000 and allowing "Shark Drake" to attack it again. "Black Ray Lancer" (1100/600) is Special Summoned. "Shark Drake" attacks and destroys "Black Ray Lancer" (Shark 3000 → 1000). Trey Sets a card.
Turn 4: Shark
Shark Normal Summons "Skull Kraken" (600/1600), with its effect activating, letting him destroy a face-upSpell or Trap Card his opponent controls. He destroys "Orichalcum Chain", thus shifting control of "Shark Drake" to Shark. "Shark Drake" attacks directly, but Trey activates his face-down "Antikythira Gear" as his opponent controls two or more monsters and declared a direct attack. This would let him take control of one of the monsters that isn't attacking and switch it to Defense Position. Shark activates his face-down "Extreme Pressure Power", letting him target and destroy a monster he controls to draw a card. He destroys "Skull Kraken", so "Antikythira Gear" resolves with no effect. The direct attack continues (Trey 3400 → 300). Shark Sets two cards.
Turn 5: Trey
Trey activates "Chronomaly Technology", letting him banish a "Chronomaly" monster from his Graveyard to draw two cards, then send a card from his hand to the Graveyard. He banishes "Mayan Machine", draws two cards and sends "Chronomaly Crystal Skull" to the Graveyard. As Shark controls monsters and Trey does not, Trey Special Summons "Chronomaly Crystal Bones" (1300/400) from his hand in Attack Position via its own effect. Its other effect activates, Special Summoning "Chronomaly Crystal Skull" from his Graveyard (900/600) in Attack Position. Trey overlays his two Level 3 monsters to Xyz Summon "Chronomaly Crystal Chrononaut" (2100/1000) in Attack Position. Trey activates the effect of "Crystal Chrononaut", detaching an Overlay Unit ("Crystal Chrononaut" ORU 2 → 1) to prevent it from being destroyed by battle this turn. Any Battle Damage from battles involving it will be inflicted to Shark instead. "Crystal Chrononaut" attacks "Shark Drake", but Shark activates his face-down "Plate Salvage", which will negate the effects of all face-up Field Spell Cards for two turns ("Shark Drake" 3100 → 2800). The attack continues (Shark 1000 → 300). Trey Sets a card.
Turn 6: Shark
"Shark Drake" attacks "Crystal Chrononaut", but Trey activates the effect of the "Chronomaly Colossal Head" in his Graveyard, banishing it change a monster he controls to Defense Position. "Crystal Chrononaut" changes to Defense Position before being destroyed. Shark activates the effect of "Shark Drake" as it destroyed a monster by battle, detaching an Overlay Unit ("Shark Drake" ORU 1 → 0) to Special Summon "Crystal Chrononaut" from Trey's Graveyard to Trey's side of the field in Attack Position with its ATK reduced by 1000 (1100/1000) and allowing "Shark Drake" to attack it again. "Shark Drake" attacks "Crystal Chrononaut", but Trey activates his face-down "Chronomaly Ley Line Power", switching the ATK of the two battling monsters. Shark activates his face-down "Sea King's Verdict", negating the effect of Trey's Trap Card since it was activated during the Battle Phase. The attack continues and "Crystal Chrononaut" is destroyed (Trey 300 → 0).
