ARC - V " anime . It first aired in Japan on July 6 , 2014 and in Canada on October 23 , 2015 . It became available with official subtitles via Crunchyroll on November 15 , 2016 . Summary . Yuya recaps that LID ' s fourth player showed him his overwhelming power and strategy , remembering the Summon ings of the Fusion , Synchro and Xyz Monster s . Adjusting his glasses , Declan declares his Battle Phase and he orders " D / D / D Flame King Genghis " to attack Yuya ' s " Performapal Whip Snake " . Quickly , Yuya activate s his Set card , " Hippo Carnival " , Special Summon ing three " Hippo Token s " in Defense Position . Additionally , they are the only monsters that Declan can attack . " Genghis " bisects one of the Tokens , and Tate cheers that Yuya protected " Whip Snake " . Gong agrees ; now Yuya can mount a counterattack ( in the dub , Gong comments that the attack got him going ) . Declan continues with his attack , having " D / D / D Gust King Alexander " attack and destroy another " Hippo Token " . Then he activates the effect of " Alexander " , since it destroyed a monster by battle ; Declan can destroy one more monster . Yuya , " Whip Snake " and the remaining " Hippo Token " all react with horror as " Alexander " destroys the final Token with another slash of its one - handed blade and leaps back to Declan ' s field . Declan orders " D / D / D Wave King Caesar " to attack " Whip Snake " , and both monsters leap forwards . " Caesar " destroys " Whip Snake " with one swing of its massive blade and leaps back to Declan ' s field as Yuya ' s LP are reduced to 3300 . Frederick curses unhappily , as Declan managed to destroy all of Yuya ' s monsters . Declan Sets a card and ends his turn . Yuya calls Declan ' s true strength amazing , admitting to being honestly shocked when he saw that Declan could control all three Summoning methods . Now it ' s Yuya ' s turn . He doesn ' t control Fusion , Synchro or Xyz Monsters , but he has his own unique power that has been given to him . He declares that the fun has only just begun , and he draws . He ' s drawn " Timegazer Magician " , and thinks to himself in satisfaction that it ' s here . " Ladies and Gentlemen ! " Yuya cheers . Apologizing to his fans for keeping them waiting , he declares that it ' s what they ' ve all been waiting for , Yuya Sakaki ' s Entertainment Dueling that only Yuya Sakaki can do . Henrietta isn ' t fazed , but Yuya ' s friends are all excited . Ally says that she ' s been waiting for this . Using the Scale 1 " Stargazer Magician " and the Scale 8 " Timegazer Magician , " Yuya Sets the Pendulum Scale . The familiar writing appears on his Duel Disk , and the twin magicians appear in the blue columns of light . Yuya explains that now he can Summon multiple monsters from Level s 2 to 7 . The large pendulum swings as Yuya chants " Swing , pendulum of the soul ! Draw an arc of light across the aether ! Pendulum Summon ! Come forth , my monsters ! " Two monsters emerge from the Pendulum portal , " Odd - Eyes Pendulum Dragon " and a new companion , " Performapal Fire Mufflerlion " . Tate cheers that there it is , the Pendulum Summon . Ally adds that Yuya brought out a new monster , too , and Frederick gets his " shivers . " Zuzu tells Yuya that it ' s time for a counterattack ( in the dub , Zuzu encourages Yuya to sic " Mufferlion " on his opponent ) , and Gong tells Yuya to do it . Skip tells Yuya that he ' s counting on him . Spotlights snap on Yuya , and he asks for everyone ' s attention . It ' s time for fire acrobatics featuring their favorite superstar , " Odd - Eyes Pendulum Dragon " ( in the dub , Yuya calls the act of " Odd - Eyes " overpowering ) . He dives from the platform , dons his goggles , and lands on the back of " Odd - Eyes " , and tells his monster " let ' s go ! " ( " Here we go , Odd - Eyes ! It ' s showtime ! " in the dub ) and declares his Battle Phase . " Odd - Eyes " attacks " Genghis " , and Yuya chants , " With those dual - colored eyes of yours , lay waste to all that lies before you ! " Leaping into the air , " Odd - Eyes " attacks with " Spiral Flame Strike " , blasting a black and crimson plume of flame at " Genghis " . The Fiend blocks the blast with its shield as Yuya explains that the effect of " Odd - Eyes " activates now - when battling a Level 5 or higher monster , battle damage is doubled . The orbs on the spines of " Odd - Eyes " glow as Yuya declares " Reaction Force ! " and Odd - Eyes adds a surge of orange flame to its blast , destroying " Genghis " and reducing Declan to 3000 LP . Tate cheers , explaining to his friends that 500 times two is 1000 total points of damage ( in the dub , Tate encourages Yuya to take down the rest of Declan ' s monsters ) . Ally yells that Yuya ' s turned the tides . Furthermore , Yuya activates the effect of " Fire Mufflerlion " , which allows a Pendulum Monster that has destroyed a monster in battle to make a second attack and gain 200 ATK . " Fire Mufflerlion " roars and lets loose an aura of flame that becomes a ring of fire . Yuya orders " Odd - Eyes " to jump through , and the Dragon leaps through the ring , with its ATK at 2700 . Tate cheers , and Zuzu is impressed that Yuya could use that move to power up " Odd - Eyes " . Gong comments that Yuya is truly a wild animal tamer ; no , a dragon tamer ( in the dub , Zuzu comments that Yuya is the best at the razzle - dazzle department ; Gong says Yuya is a natural at monster - wrangling ) ! Skip calls it real entertainment , burning and hot - blooded as Yuya targets " Alexander " for his next attack , with " Odd - Eyes " launching another " Spiral Flame Strike " . " Alexander " leaps into the air and blocks the blast with its sword , and Yuya then activates the effect of " Odd - Eyes " again , " Reaction Force " . The second surge of flame destroys " Alexander " and reduces Declan to 2600 LP as he grunts . Frederick exclaims that he can ' t stop these shivers . Yuya and " Odd - Eyes " pass by an Action Card , and Yuya bends down to snag it , commenting that he ' s on a roll today . He activates the card , " Wonder Chance " , allowing " Odd - Eyes " to attack again . " Odd - Eyes " attacks " Caesar " . Before leaping up to meet the attack , " Caesar " absorbs one of its Overlay Units into its chest , and Declan narrows his eyes . " Caesar " raises its sword , but it is destroyed in a single blast , reducing Declan to 2300 LP . Ally cheers that Yuya did it , he took out all of them , and Tate adds that on top of that , Yuya managed to take out 1700 of Declan ' s LP in one turn ( in the dub , Tate says that while the Duel was a 180 earlier , Yuya took control of it ) , while Frederick has another bout of shivers . Zuzu states that , even if his opponent controls all three Summoning methods , as long Yuya has Pendulum Summoning , he can protect You Show Duel School . Skip tells Yuya that he ' s on fire , he really is the ace of their You Show Duel School . Dismounting " Odd - Eyes " , Yuya thanks his audience for their cheers , and explains that " Fire Mufflerlion " can ' t attack this turn due to its own effect , so his attacks have come to an end , and the ATK of " Odd - Eyes " returns to normal . He bows deeply , and then he walks over to " Odd - Eyes " , congratulating it . He looks over at the cloud of smoke clearing before Declan and gasps in horror . " Caesar " , " Alexander " , and " Genghis " are all standing on Declan ' s field . Everyone is shocked , with Tate protesting that Yuya just destroyed them . Yuya asks why , and Declan explains that he activated the effect of " Wave King Caesar " . By using an Overlay Unit , " Caesar " can Special Summon all of the monsters that were destroyed during the turn ' s Battle Phase at the end of the Battle Phase . Yuya and Gong are shocked , as Declan admits that , of course , there is a risk for such a powerful ability ; on his next turn , if he controls any monsters that were Special Summoned by this effect , he takes 1000 damage for each . Frederick and Tate muse that three monsters will mean 3000 damage , more than Declan ' s 2300 LP , so Declan will lose on his next turn . Sora interrupts , pointing out that he told them that wouldn ' t happen . He takes a bite out of his chocolate bar and comments that Declan ' s too good for that . Sora is immediately proven correct as Declan activates the Trap Card , " D / D / D Human Resources " . It returns three " D / D / D " monsters from his field to the Deck , and then allows him to add two " D / D " monsters from his Deck to his hand . All three " D / D / D " monsters vanish as two cards are ejected from Declan ' s Deck , " D / D Savant Kepler " and " D / D Savant Galilei " - monsters with widened art frames . Sora points out that he told them so , with all three monsters gone , Declan won ' t take any damage on his next turn now . Frederick points out that all Declan did was return his monsters to his Deck , and Ally asks what ' s so great about the powerful ability of " Caesar " . Both Sora and Tate are worried about the two cards that Declan added to his hand , though . Zuzu tells Yuya to keep it up , and just make it through with a smile on his face using his Entertainment Dueling ( this exchange is cut from the dub ) . Yuya Sets a card ends his turn . He congratulates Declan , calling him amazing . Everything Declan does surpasses Yuya ' s expectations . He ' s looking forward to whatever surprises Declan has in store for him next , but then he scratches his nose and claims he was just kidding . Declan replies that likewise , Yuya has also done well . He has allowed Declan to see the nature of Pendulum Summoning for himself with his own eyes . Now it ' s Yuya ' s turn . He ' ll have Yuya confirm with his own eyes whether Pendulum Summoning is unique or not ( in the dub , Declan says he knows secrets about the other Summoning methods , including Yuya ' s ) . Declan draws , and then , using the Scale 1 " D / D Savant Galilei " and the Scale 10 " D / D Savant Kelper , " he Sets the Pendulum Scale . The word appears on Declan ' s Duel Disk , and two robotic pillars rise from the ground in blue columns of light , as Declan explains that he can simultaneously Summon monsters from Level 2 to Level 9 . Gong yells that those are Pendulum Monsters , and Sora and Zuzu gasp that it can ' t be ( in the dub , Gong thinks that Declan is bluffing , while Zuzu disagrees ) . " Grand power which shakes my very soul ! " Declan chants as the Pendulum Monsters work . " Arise within me and give birth to a new light that rends the darkness ! Pendulum Summon ! Come before me , my monsters ! " ( " The energy of the universe swings between the forces of the darkness and the light ! I shall now harness the power of this eternal oscillation ! " in the dub ) Unlike Yuya ' s Summon , no pendulum swings between the monsters , and only a purple mass of light surges from the portal as everyone gasps . " The three transcendent deities who rules over all kings ! " ( " Behold , the three fierce immortals who can command obedience to all ! " in the dub ) Declan chants . " D / D / D Doom King Armageddon ! " he yells as a crystalline monster descends . And it ' s not just that one , another , and another " Armageddon " descends , for a total of three , each with 3000 ATK , as Sora observes . Yuya asks how Declan can Pendulum Summon , but Declan wastes no time in moving to his Battle Phase , attacking " Odd - Eyes Pendulum Dragon " with " Armageddon " . As " Armageddon " charges an energy attack in its core , Zuzu pounds on the glass and yells Yuya ' s name , snapping him out of his daze . Yuya finds an Action Card , " Miracle " , which will prevent " Odd - Eyes " from being destroyed and halve the battle damage . " Armageddon " blasts eight strands of black and purple lightning from its body , impacting " Odd - Eyes " and reducing Yuya to 3050 LP . Declan comments that miracles only happen once , and attacks with the second " Armageddon " , destroying " Odd - Eyes " , and reducing Yuya to 2550 LP . Tate points out that Pendulum Monsters don ' t go to the Graveyard when they ' re destroyed , and Declan takes note of this as Yuya ' s Duel Disk shows " Odd - Eyes " going into Yuya ' s Extra Deck ; he also notes that the same thing will happen to " Fire Mufferlion " if it is destroyed . Declan attacks " Fire Mufflerlion " as well , Yuya frantically running around , searching for an Action Card , but he ' s unable to find one in time as the attack from the final " Armageddon " strikes , reducing Yuya to 350 LP . Tate gasps that Declan did 2200 damage in an instant . Zuzu murmurs Yuya ' s name . Yuya wonders who Declan is , and asks him how he can use Pendulum Summoning . Declan ' s only answer is to Set a card and end his turn ( in the dub , Declan replies this is none of Yuya ' s concern ) . Henrietta claps and calls Declan splendid . If he ' s mastered Pendulum Summoning to this extent , then they have no use for You Show , and they can simply crush them . Fusion , Synchro and Xyz all belong to LID . Skip is shocked that Declan would use Pendulum Summoning , and wonders just how much power Declan has . Then he notices the still shell - shocked Yuya on his screen , and he reminds Yuya that the match isn ' t over yet , and reminds him him to keep burning and be hot - blooded . Yuya agrees and urges himself to calm down , he has to protect You Show . He looks up at the three " Armageddons " , musing that those are Declan ' s Pendulum Monsters , despite Pendulum being something only given to Yuya . Then he shakes his head and tells himself not to think about it , if Yuya doesn ' t win this Duel , the Duel School will . . . Yuya declares his turn and muses that since his hand is at zero , this draw will decide everything . He draws , getting his " Performapal Partnaga " , and then he Pendulum Summons again , bringing forth the monsters that left the stage , " Odd - Eyes Pendulum Dragon " and " Performapal Fire Mufflerlion " , as well as " Partnaga " from his hand . Frederick cheers that this time Yuya brought forth three monsters at once . Gong adds that Yuya ' s still ready to fight , and Zuzu shouts encouragement . Yuya activates the effect of his " Partnaga " , target ing " Odd - Eyes " . When " Partnaga " is Special Summoned , he can increase the targeted monster ' s ATK by 300 for each " Performapal " monster he controls . " Partnaga " spreads its body out to attach to one of the horns of " Odd - EYes " and grabs the tail of " Mufflerlioin " with the hand on its own tail , causing " Odd - Eyes " to glow with yellow light and power up to 3100 ATK . Yuya thinks that everything is set : first , he ' ll use the powered up " Odd - Eyes " to destroy one " Armageddon " , using the effect of " Odd - Eyes " to double the battle damage to 200 , reducing Declan to 2100 LP , and then he ' ll power up " Odd - Eyes " again with " Fire Mufflerlion " , to 3300 ATK and have it attack again , destroying the second and reducing Declan to 1500 LP . Then , he can use his Trap Card , " One Two Jump " , to have " Odd - Eyes " attack a third time and halve the ATK of the final " Armageddon " . With Declan having 1500 LP left , Yuya can win . Yuya leaps on " Odd - Eyes " and attacks the first " Armageddon " with its " Spiral Flame Strike " , then Yuya reminds Declan that the effect of " Odd - Eyes " doubles the battle damage with a Level 5 or higher monster , and " Odd - Eyes " activates its " Reaction Force " effect , the extra fire destroying " Armageddon " and reducing Declan to 2100 LP . Declan in turn reminds Yuya that destroyed Pendulum Monsters are sent to the Extra Deck , holding up his card . He begins to activate the effect of " Fire Mufflerlion " , but Declan interrupts him with the effect of " Armageddon " . When one of Declan ' s monsters is destroyed , the remaining " Armageddons " can gain the ATK of the destroyed monster . Dark power flows into the two monsters as Declan reminds them that " Armageddon " had 3000 ATK , so the other two will gain that value . Both " Armageddons " increase to 6000 ATK , and the group look on in shock , asking how one would even defeat such a monster . Sora comments that this is going to be rough , but he alone seems excited , as everyone else believes that this is the end . Reluctantly , Yuya ends his turn and the ATK of the " Armageddons " decrease back to their substantial 3000 . Declan starts his turn and draws a card . And then both " Galilei " and " Kelper " begin shaking violently , covered in lightning . Their Pendulum Effect s appear on the cards , and their Scales shrink to 2 and 5 . This is reflected by the glowing numbers changing in the blue light columns , with the Scale of " Galilei " doubling to 2 , and the Scale of " Kepler " halving to 5 . Lightning strands extend from the two Pendulum Monsters and destroy the two " Armageddons " , much to everyone ' s shock , especially Declan ' s . Sora observes that the destruction of the monsters must have had something to do with the Pendulum Scale shrinking just now ( in the dub , Sora adds that this means Declan hasn ' t perfected Pendulum Summoning yet ) . Gong yells that it ' s a chance , and Zuzu points out that Declan can only Pendulum Summon Level 3 and 4 monsters now . This reminds Yuya of the effect of " Partnaga " , which prevents Level 4 or lower monsters from attacking , so no matter what monsters Declan summons . . . Declan muses that in the end , his monsters were just prototypes , and they were still unstable . He looks at his Set card , thinking that , in this situation . . . and then he realizes something . He begins to laugh madly , his face twisting beneath his hand . He asks himself why he didn ' t realize it until now - Pendulum Summoning is not complete yet . Yuya gasps in shock , and Declan explains that he ' s seen the possibility for evolution in Pendulum Summoning , and he ' ll have Yuya bear witness to it at this moment . Yuya can only wonder what Declan is talking about . " What did you say ? " Henrietta gasps , catching the attention of both Declan and Yuya . But she ' s not talking to them , Claude is whispering in her ear . Julia , the closest , gasps " Professor Marco was . . . ! " ( " What ' s going on ? ! " in the dub ) causing both Kit and Dipper to react as well . Henrietta calls out to Declan , who pops up a screen on his Duel Disk to communicate with Claude , who informs him of the situation , causing Declan to narrow his eyes . Declan promptly leaps from ball to ball and starts walking out of the arena . When Yuya asks Declan to wait , Declan explains he ' ll give Yuya the win ( in the dub , Yuya wonders what the move Declan was about to use was , while Declan replies that he ' ll see someday ) . Yuya asks to know Declan ' s name , and Declan tells him that his name is Declan . Declan leaves Yuya to murmur his new rival ' s name . Featured Duel : Yuya Sakaki vs . Declan Akaba . Turn 3 : Declan " D / D / D Flame King Genghis " attack s " Performapal Whip Snake " , but Yuya activate s his face - down " Hippo Carnival " , Special Summon ing three " Hippo Tokens " ( 0 / 0 each ) in Defense Position .

Yuya Pendulum Summon s " Odd - Eyes Pendulum Dragon " ( 2500 / 2000 ) and " Performapal Fire Mufflerlion " ( 800 / 800 ) , both from his hand in Attack Position . " Odd - Eyes " attacks and destroys " Genghis " , with the former ' s effect doubling the battle damage as it is battling a Level 5 or higher monster ( Declan : 4000 → 3000 LP ) . As a Pendulum Monster he controls destroyed an opponent ' s monster by battle , Yuya activates the effect of " Mufflerlion " , increasing the ATK of " Odd - Eyes " by 200 ( " Odd - Eyes " : 2500 → 2700 / 2000 ) until the end of the Battle Phase and allowing it to attack again , but " Mufflerlion " itself may not attack . " Odd - Eyes " attacks and destroys " Alexander " , with the effect of " Odd - Eyes " doubling the battle damage ( Declan : 3000 → 2600 LP ) . Yuya finds and activates the Action Card " Wonder Chance " , giving " Odd - Eyes " an additional attack . " Odd - Eyes " attacks and destroys " Caesar " ( Declan : 2600 → 2300 LP ) , with Declan activating the effect of " Caesar " , detach ing an Overlay Unit to Special Summon all monsters he controls that were destroyed by battle this turn at the end of the Battle Phase , but during his next Standby Phase , he will take 1000 damage for each one he still controls . The Battle Phase ends and Declan Special Summons " Genghis " ( 2000 / 1500 ) , " Alexander " ( 2500 / 2000 ) and " Caesar " ( 2400 / 1200 ) , all in Attack Position . The effect of " Mufflerlion " expires ( " Odd - Eyes " : 2700 → 2500 / 2000 ) . Declan activates his face - down " D / D / D Human Resources " , letting him return three " D / D / D " monsters to his Deck and add two " D / D " monsters from his Deck to his hand . He returns " Genghis " , Alexander " and " Caesar " to his Extra Deck and adds " D / D Savant Kepler " and " D / D Savant Galilei " . Yuya Sets 1 card . Turn 5 : Declan Declan activates " Galilei " ( 1 ) and " Kepler " ( 10 ) in his Pendulum Zones . Declan Pendulum Summons three " D / D / D Doom King Armageddon " ( 3000 / 1000 each ) , all from his hand in Attack Position . The first " Armageddon " attacks " Odd - Eyes " , but Yuya finds and activates the Action Card " Miracle " , halving the battle damage and preventing " Odd - Eyes " from being destroyed by battle ( Yuya : 3300 → 3050 LP ) . Another " Armageddon " attacks and destroys " Odd - Eyes " ( Yuya : 3050 → 2550 LP ) , which is sent to the Extra Deck . The last " Armageddon " attacks and destroys " Mufflerlion " ( Yuya : 2550 → 350 LP ) , which is sent to the Extra Deck . Declan Sets 1 card . Turn 6 : Yuya Yuya draws " Performapal Partnaga " .

Yuya targets " Odd - Eyes " ( " Odd - Eyes " : 2500 → 3100 / 2000 ) . At this point , Yuya envisions a plan to win the Duel : he can attack and destroy an " Armageddon " with " Odd - Eyes " ; then he can use the effect of " Mufflerlion " to give " Odd - Eyes " 3300 ATK and allow it to attack and destroy another " Armageddon " , reducing Declan ' s LP to 1500 ; then he can activate his face - down " One Two Jump " as " Odd - Eyes " has destroyed two monsters this turn , which will halve the ATK of Declan ' s third " Armageddon " and allow " Odd - Eyes " to attack it for 3600 damage . " Odd - Eyes " attacks and destroys an " Armageddon " ( Declan : 2300 → 2100 LP ) , which is sent to the Extra Deck . The effects of both remaining " Armageddons " activate ; since a monster Declan controls left the field , they each gain ATK equal to the original ATK of that monster until the end of the turn ( " Armageddons " : 3000 → 6000 / 1000 each ) . At the end of the turn , the effects of both " Armageddons " expire ( " Armageddons " : 6000 → 3000 / 1000 each ) . Turn 7 : Declan During Declan ' s Standby Phase , " Galilei " and " Kepler " appear to malfunction in their Pendulum Zones , and their Pendulum Effects appear on their cards : " Galilei " doubles its Pendulum Scale ( " Galilei " : 1 → 2 ) and sends to the Graveyard all Pendulum Summoned monsters he controls whose Levels are lower than its Scale , while " Kepler " reduces its Pendulum Scale by 5 ( " Kepler " : 10 → 5 ) and sends to the Graveyard all Pendulum Summoned monsters he controls whose Levels are higher then its Scale . Since the Levels of the " Armageddons " are higher than the Scale of " Kepler " , they are sent to the Graveyard . At this point , Declan is called away so he surrender s . Featured cards .
