"Sphere Cube Calamity: Part 2", known as "Superdreadnought Dimension Dragon!! Galaxy-Eyes Tachyon Dragon" in the Japanese version, is the eighty-third episode of the Yu-Gi-Oh! ZEXAL anime. It first aired in Japan on December 16, 2012 and in the United States on October 19, 2013.
Due to Mizar's "Number 107: Galaxy-Eyes Tachyon Dragon", Yuma is unable to continue the Duel and Kite appears to take his place. Mizar and Kite then begin a battle in which the pride of being a "Galaxy-Eyes Master" is on the line.
Mizar has just summoned "Number 107: Galaxy-Eyes Tachyon Dragon". Shocked, Yuma exclaims that he thought there were only 100 "Numbers". Astral confirms this; his memories had been split into 100 pieces. He wonders just what this "Number" is as he stares at it in stunned horror. Outside the Sphere Field, Tori turns as Shark and Rio arrive on Shark's motorcycle. Shark notices the Sphere Field and comments on how the duel has already begun. (in the dub, he wonders what monster Yuma is facing) Rio asks Tori what is happening. (this part is omitted from the dub)
Up above, Mizar notices that "Galaxy-Eyes Tachyon Dragon" is acting rather restless, and wonders if it really wants to fight that badly. (this part is omitted from the dub) Stating that he will fulfill its wish, he commands the "Number" to attack "Utopia". Yuma defends by activating the effect of "Utopia", with Astral commenting on the strength of Light Wing Shield and "Overlay Chain" together. With a smirk, Mizar asks if they really think they will survive like that. A startled Yuma states that Mizar's Battle Phase ought to have ended; Mizar simply comments on Yuma's naivety before activating the effect of "Tachyon Dragon": once per turn, when all possible attacks have been used up, he can detach an Overlay Unit from "Tachyon Dragon" to negate the effects of all other monsters on the field and return their ATK and DEF to normal.
Applying "Tachyon Transmigration", "Tachyon Dragon" reverts to its sealed form and emits a rainbow aura which forces "Utopia" back into its own sealed form. A shocked Astral and Yuma bear witness to the remaining parts of the effect of "Tachyon Dragon": if a card or effect was activated during this Battle Phase, then "Tachyon Dragon" gains 1000 ATK. Also, Mizar states that during the turn in which this effect is activated, "Galaxy-Eyes Tachyon Dragon" can attack an additional time. A horrified Astral realizes the implications of a monster that can alter both the past and future to its own advantage (in the dub, Astral tells Yuma to double their efforts and Duel like never before if they want to win). Mizar commands "Tachyon Dragon" to attack with "Tachyon Spiral of Destruction". Astral begins to warn Yuma about the attack, but before he can elaborate, "Utopia" is obliterated and Yuma is hurled painfully into the Sphere Field, which shocks him on impact.
Tori calls out Yuma's name as Shark grits his teeth in anger. Astral pleads for Yuma to wake up as Mizar comments on how weak humans are, noting how much damage Yuma received from just one attack of "Tachyon Dragon". (in the dub, Astral asks if Yuma is hurt badly. Mizar replies that he is and that he is nearly broken after a single attack from "Tachyon Dragon") Yuma struggles to rise, and Mizar encourages him to do so, noting how he is just a nuisance if he does not continue. He orders Yuma to "stand up, lose miserably, and hand over [his] "Numbers" to [him]." (in the dub, Mizar encourages Yuma to rise, and he can knock him down again, while adding that Yuma should think about how "Utopia" slipped away from him.) Yuma attempts to respond, but he stumbles, and Mizar continues to mock him, asking if he cannot even stand up. (in the dub, Mizar taunts Yuma, saying that he is depriving him of his sport, and that challenging humans is a rare treat) He then offers him the chance to surrender, which Yuma refuses, knowing that if he loses, he will lose Astral as well, which he cannot accept. He then falls unconscious.
Shark resolves to take Yuma's place in the duel, but before he can do so, Kite flies in on Orbital 7 and declares that he will take Yuma's place. Shark begins to tell Kite to stay out of this, but then Rio, glowing red, seems to fall into a trance, notes that "Galaxy-Eyes" is calling on "Galaxy-Eyes". Shark listens as Rio elaborates that the two dragons, which have encountered once before, are drawn together once again after transcending distant dimensions. Shark notes that she said two dragons.
Mizar notices something different about Kite. At that moment, a silhouette of "Galaxy-Eyes Photon Dragon" appears and roars, which its Tachyon "brother" responds to. The Sphere Field begins to react to the presence of both dragons and teleports Kite in. Yuma opens his eyes and murmurs Kite's name. Kite tells the two to leave the rest to him, to which Astral apologizes. Kite replies that he shouldn't worry; this is his issue as well. "There can only be one person who uses Galaxy-Eyes," he states, "and that person is me." Mizar asks if he's finished his greeting to "that loser." Kite states that if Mizar welcomed him here, then he also wants to fight him. (in the dub, Mizar asserts that he is the true "Galaxy-Eyes" master, while Kite replies that Mizar made two mistakes: underestimating his confidence and bringing him to the Sphere Field) Mizar corrects him, stating that his "Galaxy-Eyes" challenged Kite's. Kite then asks if he has no objections to him taking Yuma's place; Mizar affirms that he has none. Mizar Sets two cards and ends his turn, with the ATK of "Tachyon Dragon" returning to normal.
Kite now begins his turn continuing with Yuma's remaining 2500 Life Points. He plays "Photon Trade" discarding a "Photon" monster and drawing two cards before Special Summoning "Photon Thrasher" as he controls no monsters. Then he Normal Summons "Photon Crusher". Shark and Rio note that Kite hs two monsters with at least 2000 ATK points, and Kite Tributes his two monsters with 2000 or more ATK to Special Summon "Galaxy-Eyes Photon Dragon". Both monsters send out shockwaves that, as Rio explains, resonate with each other. Astral is quite surprised at the two monsters. The shockwaves eventually damage the ground, causing large chasms to open up. Orbital 7 comments that the phenomenon is incomprehensible. Meanwhile, unseen by the others, Ray approaches on a hillside to watch the Duel.
As both players witness the animosity between their two monsters, Mizar comments on how the legend appears to be correct. (in the dub, Mizar says that having two "Galaxy-Eyes" monsters is as rare as it is risky) Kite asks what he means, but Mizar replies that a loser such as Kite doesn't need to know about it. Kite decides to win to get his answer and declares the attack of "Photon Dragon", then activates its effect to banish both monsters, sending the last Overlay Unit of "Tachyon Dragon" to the Graveyard. At the end of the battle, both monsters are Special Summoned as Kite explains that "Photon Dragon" will gain 500 ATK for each Overlay Unit that "Tachyon Dragon" had. "Photon Dragon" absorbs the Overlay Unit as its ATK rises to 3500.
Kite comments that removing the Overlay Unit from "Tachyon Dragon" has pulled out its fangs. Mizar asks if that's so, and activates his Set "Instant Overlay", allowing him to attach it to an Xyz Monster that has no Overlay Units. He comments that it's a pity, and then activates the effect of "Tachyon Dragon", detaching an Overlay Unit to negate the effects of all other monsters on the field and return their ATK and DEF to normal. "Tachyon Dragon" reverts to its sealed form as Mizar declares "Tachyon Transmigration!" "Photon Dragon" loses its blue light as the rainbow aura of "Tachyon Dragon", which returns to its dragon form, negates the effect of "Photon Dragon" and returns it to its base 3000 ATK. Since Mizar activated "Instant Overlay," "Tachyon Dragon" also gains 1000 ATK. Kite knows that he can't use the effect of "Photon Dragon" anymore, but thinks that he can use "Lumenize" to protect "Photon Dragon". He wonders if this will decide it, and Sets the card to end his turn, also returning the ATK of "Tachyon Dragon" to 3000.
Mizar draws and activates "Energy Attractor", allowing him to use it and Kite's Set card as "Tachyon Dragon's" Overlay Units. Red beams strike the Set "Lumenize", transforming it into the twin Overlay Units which come to rest around "Tachyon Dragon." Mizar remarks that judging by the look on Kite's face, he's lost his trump card to reverse the situation. Astral adds that "Tachyon Dragon" now has two Overlay Units. Mizar then attacks, activating "Tachyon Drive", which allows him to prevent other Spell and Trap cards from affecting a "Tachyon Dragon" monster. "Tachyon Dragon" attacks, destroying "Photon Dragon," as Kite grimly reflects that "Numbers" can only be destroyed by other "Numbers". (in the dub, Kite remarks that even though his "Photon Dragon" was taken out, it will rise again and it will be Mizar who will fall) Mizar then activates the effect of "Tachyon Dragon," and it uses "Tachyon Transmigration" again. Shark curses that Mizar used the effect again. Due to its effect, as Mizar activated "Tachyon Drive", "Tachyon Dragon gains 1000 ATK and it can attack a second time.
Outside the Sphere Field, Rio observes that "Tachyon Drive" not only protects "Tachyon Dragon," but allows it to crush the opponent. Shark mutters that this is bad. (this part is cut from the dub) Mizar tells Kite that he should feel honoured to meet his end at "this noble dragon's claws" (in the dub, Mizar tells Kite that he will end his deranged hopes of winning) and declares a direct attack with "Tachyon Spiral of Annihilation". The attack strikes Kite, who disappears behind a cloud of smoke. Yuma whispers Kite's name as Mizar declares himself the true "Galaxy-Eyes" user, (in the dub, Mizar says that Kite failed his "Galaxy-Eyes" once again) only for the smoke to clear to reveal Kite, Life Points at 500.
Mizar is horrified, and asks how Kite survived, then the smoke clears further to reveal "Galaxy-Eyes Photon Dragon". Kite explains that he activated the effect of "Photon Specter" from his Graveyard (sent there via "Photon Trade"), pointing out that "Tachyon Drive" only affects Spell and Trap Cards. It allowed him to Special Summon a "Photon" monster from his Graveyard in Attack Position with its effects negated and its ATK reduced by 1000, as well as preventing the monster from being destroyed in battle during the turn it was Summoned. Thus, the attack targeted "Photon Dragon," with 2000 ATK, so Kite's total damage was 2000. Mizar is disgruntled, but ends his turn, and the ATK of "Tachyon Dragon" returns to normal.
Kite's Duel Gazer tattoo glows as he draws. He activates "Monster Reborn" to revive "Photon Thrasher," and Normal Summons "Photon Circle". Then he activates "Upshift", raising the Levels of all the monsters on his field to that of the one with the highest Level - 8. Noting that Kite has three Level 8 monsters, Mizar wonders if it's coming. Kite screams as a red aura surronds him, and he overlays the three monsters to Xyz Summon "Neo Galaxy-Eyes Photon Dragon." Observing the gigantic dragon, Mizar whispers in anticipation. Kite uses the effect of "Neo Photon" to negate the effects of every other face-up card on the field as it was Xyz Summoned using "Galaxy-Eyes Photon Dragon" as Xyz Material, declaring "Photon Howling". Mizar realizes that this effect has taken away the immunity to destruction by non-Numbers of his "Number", and wonders if this is why it's regarded as a fearsome "Numbers killer." Kite then activates the effect of "Neo Photon", detaching an Overlay Unit to detach the Overlay Units from all other Xyz Monsters on the field, and then gaining 500 ATK for each one. "Neo Photon" powers up to 5000 ATK, and Kite declares its attack with "Ultimate Photon Stream of Destruction". The blast destroys "Tachyon Dragon" in a massive explosion, which blasts Mizar into the Sphere Field, reducing his Life Points to 2000. Kite ends his turn. Mizar begins to laugh, calling Kite very good - that's what a Galaxy-Eyes user should be. (this part is cut from the dub)Mizar draws, asking Kite to let him use this card as well. He plays his own "Monster Reborn", reviving "Number 107: Galaxy-Eyes Tachyon Dragon". Both it and "Neo Galaxy-Eyes Photon Dragon" roar at each other. Mizar grins - if it comes to this, it is only fitting that he fight for real. He declares Barian Battlemorph, and glows with light, transforming into his true form. Down below, everyone looks at the Barian in shock, as Astral and Kite observe Mizar's true form. Mizar says that he'll show them the true power of Barian, and activates "Rank-Up-Magic Barian's Force", allowing him to use an Xyz Monster as an Overlay Unit to summon a "CXyz" monster". Using "Tachyon Dragon" as Xyz Material, he chants "The power of Barian, born from Chaos, dwell in the Numbers to create a new Chaos!" Astral and Kite look on in shock as Mizar declares a "Chaos Xyz Evolution", and a door resembling the Barian emblem appears as Mizar chants "Pierce through the galaxy and revive from before the creation of time!" As the door shatters open, he yells, "Surpass the eternal dragon's star! "Chaos Number 107! Neo Galaxy-Eyes Tachyon Dragon!" (in the dub, Mizar chants "Barian power born from chaos, surge through my Number and bestow it with great might! Go Chaos Xyz Evolution! Face the multiverse and ignite new life into my great beast!") The evolved "Tachyon Dragon", a three headed dragon wreathed in flames, roars as it appears (its ATK value unseen).
Kite is shocked to see a "Neo Galaxy Eyes" form of "Tachyon Dragon". Both dragons roar at each other, and Mizar protests that it's not working - there's too much energy. The energy from "Neo Galaxy-Eyes Tachyon Dragon" begins to engulf the Sphere Field and forces Mizar back into his human form, who tells Kite to save to duel for later, and he tells him his name. He vows to control both "Galaxy-Eyes" one day, and vanishes in the smoke. The Sphere Field begins to break up, and Tori cries out Yuma's name. Kite's red aura fades as the field dismisses itself entirely, and he and Yuma begin to fall. Orbital 7, transforming into his glider form, swoops in and rescues Kite, while Shark runs to save Yuma, who hits the ground and rolls towards the chasm that the two "Galaxy-Eyes" monsters created. Shark grabs Yuma as Yuma falls over the edge, but it breaks under Shark's weight, and they fall screaming into the chasm, with Tori, Rio, Astral and Kite looking on in horror.
Yuma Tsukumo vs. Mizar
Duel continues from the previous episode.
Turn 2: Mizar
"Number 107: Galaxy-Eyes Tachyon Dragon" attacks "Number 39: Utopia", but Yuma activates the effect of "Utopia", detaching an Overlay Unit ("Utopia" ORU 2 → 1) to negate the attack. Mizar activates the effect of "Tachyon Dragon", detaching an Overlay Unit ("Tachyon Dragon" ORU 2 → 1) to negate the effects of all other monsters on the field. For each card effect that resolved during the Battle Phase, "Tachyon Dragon" will gain 1000 ATK until the End Phase. It may also attack again. The effect of "Utopia" resolves ("Tachyon Dragon" 3000 → 4000). "Tachyon Dragon" attacks and destroys "Utopia" (Yuma 4000 → 2500).
Kite Tenjo vs. Mizar
Turn 2: Mizar
Mizar Sets a card.
Turn 3: Kite
Kite activates "Photon Trade", which allows him to draw two cards at the cost of sending a "Photon" monster from his hand to the Graveyard. He sends "Photon Specter" (0/0), and draws "Photon Thrasher" and "Lumenize". As he controls no monsters, he Special Summons "Photon Thrasher" (2100/0) from his hand in Attack Position via its own effect. He then Normal Summons "Photon Crusher)" (2000/0). Kite Tributes his two monsters with 2000 or more ATK to Special Summon "Galaxy-Eyes Photon Dragon" (3000/2500) from his hand in Attack Position via its own effect. "Photon Dragon" attacks "Tachyon Dragon", with Kite activating the effect of "Photon Dragon", banishing both monsters until the end of the Battle Phase. As "Tachyon Dragon" is an Xyz Monster, its remaining Overlay Unit ("Radius, the Half-Moon Dragon") is sent to the Graveyard. The Battle Phase ends and both monsters are Special Summoned, with "Photon Dragon" gaining 500 ATK as an Overlay Unit was sent to the Graveyard via its effect (3000 → 3500). Mizar activates his face-down "Instant Overlay", which allows him to attach this card as an Overlay Unit to "Tachyon Dragon" as it doesn't have any Overlay Units ("Tachyon Dragon" ORU 0 → 1). He then activates the effect of "Tachyon Dragon", detaching the overlaid "Instant Overlay" ("Tachyon Dragon" ORU 1 → 0) to negate the effect of "Photon Dragon" and returning its ATK to its original value (3500 → 3000). Kite's hand contains "Photon Circle", "Lumenize" and "Upshift". Kite Sets a card.
Turn 4: Mizar
Mizar activates "Energy Attractor", letting him target an Xyz Monster that has no Overlay Units and attach this card and one of his opponent's Set cards to it as Overlay Units, but he may not Normal or Special Summon this this turn. He targets "Tachyon Dragon", giving it two Overlay Units ("Tachyon Dragon" ORU 0 → 2) before detaching one of them ("Tachyon Dragon" ORU 2 → 1) to activate its effect. "Tachyon Dragon" attacks "Photon Dragon", with Mizar activating the Quick-Play Spell Card "Tachyon Drive". This lets him target a "Tachyon Dragon" monster and make it immune to Spell/Trap Cards this turn. As both monsters have the same ATK, "Photon Dragon" is destroyed, but "Tachyon Dragon" is not as "Photon Dragon" is not a "Number" monster. One card effect resolved during the Battle Phase, so the ATK of "Tachyon Dragon" increases by 1000 via its own effect (3000 → 4000) and may attack again. "Tachyon Dragon" attacks directly, but Kite activates the effect of the "Photon Specter" in his Graveyard, banishing it to Special Summon a "Photon" monster from his Graveyard, which cannot be destroyed by battle, but its ATK will be reduced by 1000 and its effects negated. He Special Summons "Photon Dragon" (3000 → 2000/2500). It becomes the new attack target (Kite 2500 → 500).
Turn 5: Kite
Kite activates "Monster Reborn", Special Summoning "Photon Thrasher" (2100/0) from his Graveyard in Attack Position. He then Normal Summons "Photon Circle" (1000/1000). He activates "Upshift", targeting "Photon Dragon", causing all monsters he controls to have their Levels change to that of "Photon Dragon" until the End Phase. Kite overlays his three Level 8 monsters to Xyz Summon "Neo Galaxy-Eyes Photon Dragon" (4500/3000) in Attack Position. Since "Photon Dragon" was used as an Overlay Unit, the effects of all other face-up cards are negated. He activates its second effect, detaching an Overlay Unit ("Neo Photon" ORU 3 → 2) to send all of the Overlay Units from "Tachyon Dragon" to the Graveyard ("Tachyon Dragon" ORU 1 → 0), increase the ATK of "Neo Photon" by 500 for each one (4500 → 5000) and give it an additional attack for each Overlay Unit sent to the Graveyard (thus only getting to attack once, just like in a normal situation). "Neo Photon" attacks and destroys "Tachyon Dragon" (Mizar 4000 → 2000).
Turn 6: Mizar
Mizar activates "Monster Reborn", Special Summoning "Tachyon Dragon" (3000/2500) from his Graveyard in Attack Position. Mizar activates "Rank-Up-Magic Barian's Force", Ranking Up "Tachyon Dragon" and performing a Chaos Xyz Evolution to Special Summon "Number C107: Neo Galaxy-Eyes Tachyon Dragon". Its power threatens to destroy the Barian Sphere Cube, so Mizar cancels the Duel.
- When Mizar constructed the Overlay Network using "Rank-Up-Magic Barian's Force" to Rank-Up Number 107: Galaxy-Eyes Tachyon Dragon, he stated he was constructing it with two monsters, instead of 1. This is corrected in the dub.
- When "Number 107: Galaxy-Eyes Tachyon Dragon" finished using its effect against "Galaxy-Eyes Photon Dragon" it is still shown to have 1 Overlay Unit, when it should have had none.
- When Kite looks at his hand after "Tachyon Dragon" used its effect, the cards have the old card backings. This was corrected in the dub.
The following cards appeared in this episode. Cards in italics debuted here.
