'''Quattro''', known as '''IV''' in the Japanese version, '''Four''' in the Italian version, and born '''Thomas Arclight''', is a character appearing in the ''[[Yu-Gi-Oh! ZEXAL]]'' anime. He is a [[Number Hunter]] and the Champion of Asia. He was involved in [[Reginald Kastle|Shark]]'s [[Rio Kastle|sister]]'s accident which resulted in her being hospitalized. He is the most violent sibling of the [[Vetrix Family]], with the majority of his actions motivated by the prospect of restoring his [[Vetrix|father]] to his former form and sanity. Upon his defeat, he apologizes to Shark and implores him to save his father.

==Design==
===Appearance===
[[File:IV's symbol.jpg|thumb|left|Quattro's crest.]]
Quattro has a long, cross-like scar running down the right side of this face, and like his brothers, [[Trey]] and [[Quinton]], has a crest on his body; his crest is purple and on his right hand, which resembles fire and lightning. He has a purple [[Duel Gazer]]-like pattern that appears around his eye similar to his brothers, [[Kite Tenjo]], [[Dextra]] and [[Nistro]], although he has worn a regular Duel Gazer in the past.

[[File:IV's Duel Disk (Back).jpg|thumb|right|200px|Quattro's [[D-Pad]].]]
He has large, spiky layered dark red and yellow hair and dark red eyes. Like Trey and Quinton, he wears formal medieval-style attire that consists of a long flowing coat with white pants, boots and a shirt which all feature a curly, high-class pattern. Quattro's [[D-Pad]] has the appearance of a red blade which separates into three sections. He highly resembles Takuto Tsunashi from the anime ''[[wikipedia:Star Driver|Star Driver]]''.

===Personality===
At first, Quattro acted as a sadistic and malevolent Duelist who wanted to make his opponents suffer, with what he calls his "fanservice", in order to win (in the dub, he refers to it as "spoiling" his fans"). When in the presence of his fans, his personality becomes a facade as he hides his true nature and becomes a "noble" and "well-mannered" person who acts friendly and benevolent as well as adopts a sweet and slow-tempered demeanor. He sees his fans as bad Duelists and challenges them as his "fanservice". When he Duels, he initially praises their skills and lets them think they have the upper hand. When his opponents fall into his trap he shows his real self and defeats them cruelly, going so as far as to keep attacking his opponents even if they have no [[Life Points]] and claiming his "fanservice" must continue. He even went so far as to show a [[Hart Tenjo|child]] getting tortured on a television screen to the others for his pleasure.<ref name="ep42">{{episode|Yu-Gi-Oh! ZEXAL|42|ref}}</ref>

Beneath his malevolent behavior, Quattro shows clear signs of insecurity due to the fact that his family had suffered at the hands of [[Dr. Faker]]. He even goes far to justify this by making his opponents suffer by any means possible, and feels otherwise frustrated and angered when his "fanservice" is ruined.<ref name="ep43">{{episode|Yu-Gi-Oh! ZEXAL|43|ref}}</ref> He also regrets some of the transgressions he has done, describing them as "inhuman", all for his [[Vetrix|father]]'s sake. Like his brothers, he only followed Vetrix's orders and wanted to defeat Dr. Faker with hopes that doing so returns Vetrix to his normal self, Byron Arclight.<ref name="ep58">{{episode|Yu-Gi-Oh! ZEXAL|58|ref}}</ref>

Quattro argues a lot with his brothers, showcasing that he is willing to let his anger get in the way of their true goal and doesn't always follow [[Vetrix]]'s orders and as he puts it, "grovels" to him, unlike Trey and Quinton. He also seems to be intimidated of Quinton after getting mad at him for talking back to Vetrix.<ref name="ep33">{{episode|Yu-Gi-Oh! ZEXAL|33|ref}}</ref> Despite this, after Trey was brutally defeated by [[Kite Tenjo]] in their Tag-Team Duel, Quattro shows his concern for him, proving that he does care for his brothers.<ref name="ep43">{{episode|Yu-Gi-Oh! ZEXAL|43|ref}}</ref> He showed a more caring side when Trey was comatose by defending Trey when Vetrix said he was disappointed with him and Trey.<ref name="ep50">{{episode|Yu-Gi-Oh! ZEXAL|50|ref}}</ref>

As a child, Quattro was not the brutal Duelist he was before, but he had a tendency to tease [[Trey]] like normal brothers do and kept taking his cards. He also had respect for Quinton back then as he returned Trey's cards when Quinton told him to.<ref name="ep46">{{episode|Yu-Gi-Oh! ZEXAL|46|ref}}</ref>

When pretending to be kind, he also refers to himself using the pronoun "boku", but switches his pronoun to his usual "ore" after showing his true self.

After his father had reformed, Quattro still maintains his boastful attitude and his old habit of saying "fanservice", but had become more friendly. Still remorseful about his actions towards Rio, he developed an empathy for her, as he can't help but feel sorry for her suffering at [[Chironex]]'s poison. Quattro also displayed a childish side, complaining about Chironex's "[[Number 4: Stealth Kragen]]" simply because of the "4" in its' name, which Quattro proclaimed the number was his "trademark".<ref name="ep114">{{episode|Yu-Gi-Oh! ZEXAL|114|ref}}</ref> He also expressed gratitude for what Yuma and Shark had done for his family.<ref name="ep115">{{episode|Yu-Gi-Oh! ZEXAL|115|ref}}</ref>

===Abilities===
Quattro's [[crest]] grants him various powers. It protects him from having "[[Number]]s" extracted from him, rendering [[Photon Hand]] useless.<ref name="ep44" /> He can produce portals to quickly travel and escape.<ref name="ep44" /><ref name="ep58" />

His crest comes with a price - it is directly connected to his soul, and should he lose a Duel while wielding a powerful "Number", he will fall comatose.<ref name="ep65">{{episode|Yu-Gi-Oh! ZEXAL|65|ref}}</ref> He and his brother, Quattro later acquired a bracelet that was invented by their brother, Quinton, granting them the abilities of their father's crest once again.<ref name="ep114">{{episode|Yu-Gi-Oh! ZEXAL|114|ref}}</ref>

[[File:IV's_bracelet.png|thumb|Quattro's Bracelet]]
He is capable of [[Number Hunter|collecting]] "Numbers"<ref name="ep33" />, using a process similar to [[Astral]]'s.<ref name="ep115" />

Like his brothers, Quattro also uses the bracelet invented by Quinton, though the stone on his bracelet is purple.<ref name="ep115" />

===Etymology===
Quattro's Japanese name is the Roman numeral for four. <!--Do not move this to a trivia section. Trivia sections are discouraged if the information can fit in another section. Bulleted lists are not preferred formatting.-->The number of "[[Number 15: Gimmick Puppet Giant Grinder]]" is a pun on Quattro's own name, since "I" alone is the roman numeral "one" and "V" is the numeral "five", forming "15". Quattro's second [[Number]] , "[[Number 40: Gimmick Puppet of Strings]]" is based on the true meaning of Quattro's name, instead of breaking it down. His real first name, Thomas, means "twin" which might refers to him hurting Shark's twin sister.

In the dub, his name is in Italian, Quattro, which means "four".

==Biography==
===History===
[[File:Young_Tron's_Family.png|thumb|left|Quattro with his family.]]
In his younger days, Thomas Arclight lived with his brothers and their father, [[Vetrix|Byron]], lived a happy life with their dog, where he was an innocent, mischievous and playful child. On a winter night, their father gave [[Trey|Michael]] a ''[[Duel Monsters]]'' card - "[[Chronomaly Aztec Mask Golem]]", which Michael showed to Thomas in his excitement. Thomas was jealous because only Michael received a card and stole "Mask Golem" from him. [[Quinton|Chris]] told him to give his card back and stop squabbling or their father would scold them and then promised to teach both of them how to Duel.<ref name="ep46">{{episode|Yu-Gi-Oh! ZEXAL|46|ref}}</ref>

[[File:Young III and IV.png|thumb|right|Trey and Quattro during their childhood.]]
His father became involved in [[Dr. Faker]]'s experiments, but Faker eventually betrayed both him and [[Kazuma Tsukumo]], sending them to another dimension as sacrifices to open the door to alternate dimensions.<ref name="ep55" /> As Byron didn't return from the trip, Michael and Thomas were were sent to an orphanage, while Chris remained at Dr. Faker's facility in an attempt to learn of their father's fate. However, after learning [[Kite Tenjo]] and [[Hart Tenjo]] were Faker's sons, Chris left [[Heartland]] with his brothers.<ref name="ep56">{{episode|Yu-Gi-Oh! ZEXAL|56|ref}}</ref> Their father returned years later, but his form warped into that of a child. He took the name "Vetrix" and began plotting revenge, with Thomas and his brothers aiding him. Thomas became known as "Quattro".<ref name="ep55" /> Vetrix imbued each of his sons with a [[crest]], which granted them great power. In exchange, the crest was connected directly to their souls. Therefore, if they were lose to a Duel while wielding a powerful "Number", they would fall comatose.<ref name="ep65" />

[[File:IV saves Shark's sister.jpg|thumb|left|200px|Quattro saves [[Rio Kastle|Rio]] from the fire.]]
As part of Vetrix's plan, Quattro was told to [[Duel]] [[Rio Kastle]]. He played a card called "[[Flaming Hell Blessing]]", which somehow set the building on fire. Quattro carried her to safety, with his face being scarred in the process, but she was critically injured in the blaze.<ref name="ep58">{{episode|Yu-Gi-Oh! ZEXAL|58|ref}}</ref>

[[File:IV in the National Duel Circuit.png|thumb|right|Quattro in the [[National Duel Circuit]].]]Quattro participated in the [[National Duel Circuit]], where he faced Rio's brother, [[Reginald Kastle|Reginald]] in the finals.<ref name="ep12">{{episode|Yu-Gi-Oh! ZEXAL|12|ref}}</ref> He set Reginald up to be disqualified by planting his Deck on top of a pot, so that it would fall and end up scattered on the floor in the break room. That way, Quattro ensured Reginald would see it, though Reginald himself was unaware of that until Quattro himself told him later.<ref name="ep26">{{episode|Yu-Gi-Oh! ZEXAL|26|ref}}</ref>

===Yu-Gi-Oh! ZEXAL===
====World Duel Carnival Preliminaries====
[[File:IV in the WDC.png|thumb|left|Quattro on the first day of the [[WDC]].]]
Quattro reappeared to Reginald (who was now using the nickname "Shark") and lured him to a building in construction by throwing a "[[Mirror Force]]" card at him. Shark asked why he did that, and Quattro responded that it was just a form of greeting before the [[World Duel Carnival]]. Shark responded that he won't participate in the tournament, and Quattro asked if Shark is still influenced by what happened at the Duel Circuit. He revealed that he knows about Shark's sister, who got into an accident. He told Shark that he intentionally got him disqualified, and even implied that he caused the accident that injured Shark's [[Rio Kastle|sister]]. Shark was enraged by this, and Quattro taunted him, saying that on that day, he became the Duel Champion of the Far East. Quattro threw a [[Heart Piece]] to Shark, telling him to try to defeat him in the World Duel Carnival. After that Quattro approached [[Vetrix]], who was watching cartoons. He told him that he did as he was ordered - Shark will participate in the WDC. Quattro asked why Vetrix wanted Shark to enter the World Duel Carnival as he already has given up on being a Duelist. Vetrix responded that he is needed for when all the "[[Number]]s" cards are collected. Quattro stated that he doesn't care as long as he can drag Shark into hell again.<ref name="ep26" />

[[File:InsultIVandV.jpg|right|200px|thumb|Quattro arguing with Quinton.]]
Quattro functioned as the [[Number holder|Number Hunter]] for the Vetrix Family, collecting "[[Number]]s" by luring and defeating his own fans, who he considered to be terrible Duelists and calling this his "fanservice". During the morning of the second day of the [[World Duel Carnival]], Quattro continued to do this by studying the opponents which are available within the WDC via sheets, which contain information on them and their [[signature card]]s. Here, he throws cards at them in order to choose an opponent. Seeing this, [[Quinton]] commented that he is too brash and suggested he treat the "Numbers" he's collected better. Angered by Quinton challenging his ethics, he suggested Quinton try collecting "Numbers" himself and challenged him but is quickly shot down by Quinton being reinforced by [[Trey]] and Vetrix. After insulting Vetrix, Quinton rises to his feet and tells him he won't tolerate that, Quattro then quickly backs off. <ref name="ep33" />

[[File:IV Bronk Caswell duel.png|thumb|left|Quattro Dueling [[Bronk Stone|Bronk]] and [[Caswell Francis|Caswell]].]]
Later on in the day, Quattro agreed to meet [[Bronk Stone]] and [[Caswell Francis]] in order to sign their [[Duel Disk]]s, but had an ulterior motive to entice them to a hidden location so he can Duel them with his "Numbers" and reveal his real personality without allowing the public to see him as his true self. He suggested a [[Battle Royal]], which they agreed to. During the Duel, he allowed them to get the upper-hand by Summoning their aces, "[[Antidote Nurse]]" and "[[Tin Archduke]]". This was all a ploy as he lured them into [[Xyz Summon]]ing so he could perform two [[One Turn Kill|OTK]]s with his "[[Number 15: Gimmick Puppet Giant Grinder]]" and "[[Gimmick Puppet Princess]]". His personality changed at this moment from the friendly and noble champion of the East, to a merciless and evil person who enjoyed the pain of others, laughing when his monster hurt Bronk and Caswell. After the Duel, Shark arrived on his motorbike, making Quattro smirk.<ref name="ep33" /> Quattro intended to Duel Shark then and there, but was stopped when Trey snared Shark with a [[Duel Anchor]], telling Quattro that Vetrix's orders are absolute - Trey is to Duel Shark first. Quattro revealed that he already had a full [[Heart Piece]], and told Shark he'll be waiting in the finals and then departed.<ref name="ep34">{{episode|Yu-Gi-Oh! ZEXAL|34|ref}}</ref>

[[File:Zexal-41 duel.png|thumb|200px|right|Yuma and Kite vs. Trey and Quattro.]]
After Quinton brought [[Hart Tenjo]] to an abandoned gallery, Quattro watched as Vetrix begins his ritual in order to transfer all of Hart's powers and memories to himself. As the ritual continued, Hart began to feel more and more pain, which amused Quattro as he watched intently. After [[Yuma Tsukumo]] and [[Kite Tenjo]] break into the gallery, Quinton sends Quattro and Trey to stop them from reaching the ritual in order for it to complete. They then appear before the pair, attaching their [[Duel Anchor]]s to them, initiating a [[Tag-Team Duel]].<ref name="ep41">{{episode|Yu-Gi-Oh! ZEXAL|41|ref}}</ref>

[[File:IVPressureWorld.jpg|200px|thumb|left|Quattro, confident that the [[String Counter]]s from "[[Number 40: Gimmick Puppet of Strings]]" will ensure his and [[Trey|his brother]]'s victory.]]
As the Duel began, Quattro instantly targeted Kite as he sees him as the bigger threat. When Yuma Summoned "[[Number 39: Utopia]]", Quattro and Trey instantly know that they have to win this Duel rather than merely stall for Vetrix's ritual to finish. After Yuma Summoned "Utopia", Quattro began to target him, destroying "Utopia" straight after it was Summoned via "Number 15: Gimmick Puppet Giant Grinder". After seeing that Yuma and Kite were beginning to work together, Quattro decided to anger Kite to break those bonds by showing him a video of Hart being tortured through Vetrix's ritual. Angered by this, Kite continued to damage Yuma through "[[Photon World]]" in an attempt to rush the Duel and beat them as soon as possible. This, however was quickly stopped as Quattro and Trey had a strategy to stop Kite's "[[Galaxy-Eyes Photon Dragon]]" through "[[Stonehenge Shield]]", allowing Trey's "[[Number 33: Chronomaly Machu Mech]]", to inflict 3000 damage to Kite.<ref name="ep42" /> As the Duel continued, Yuma constantly kept intercepting Quattro's and Trey's attempts at defeating Kite, causing Quattro to get extremely angry with Yuma. Yuma managed to Summon his "[[Number C39: Utopia Ray]]" and defeated Quattro's ace, but Quattro struck back by [[Xyz Summon]]ing his other "Number" card, "[[Number 40: Gimmick Puppet of Strings]]". Despite this, Kite managed to Summon "[[Neo Galaxy-Eyes Photon Dragon]]" and defeat Trey in a single attack. Quattro screamed his brother's name and when Kite talked to him, he turned to Kite with a furious expression on his face, but any retort was cut off when he realized that he was next, and Kite attacked again, defeating Quattro as well.<ref name="ep43">{{episode|Yu-Gi-Oh! ZEXAL|43|ref}}</ref> After the Duel ended, Kite tries to steal Quattro's soul and "Numbers" using [[Photon Hand]], but was unable to as Quattro's crest protected him. He vowed to get revenge on Kite and Yuma and departed with Trey and Vetrix.<ref name="ep44">{{episode|Yu-Gi-Oh! ZEXAL|44|ref}}</ref>

====World Duel Carnival Finals====
[[File:IVsigningautographs.jpg|right|200px|thumb|Quattro signing autographs.]]
After Yuma and Astral defeated Trey, resulting in him falling unconscious, Quattro implored that Vetrix give him new powers so he could defeat Yuma. Vetrix responded that he's disappointed in both Trey and Quattro. Quattro angrily replied that Trey fought against the [[Astral|Original Number]] for Vetrix, but he lost and ended up bedridden. Vetrix responded that what he wants are results and if Trey and Quattro can't give them to him, he has other options - like Shark. He told Quattro that their role was to lure him out, which angered Quattro, who proceeded to confront Shark at the World Duel Carnival Finals party, who told him he would gamble everything he has to defeat Quattro.<ref name="ep50">{{episode|Yu-Gi-Oh! ZEXAL|50|ref}}</ref>

[[File:IV and Ryoga on the coaster.jpg|thumb|200px|left||Quattro being followed by Shark on the [[Duel Coaster]].]]
The next day, the [[Duel Coaster]] began, Quattro witnessed Shark defeating [[Green Coat Duelist|an opponent]] with his "[[Jawsman]]" and complemented him, saying he's Dueling magnificently. Shark vowed not to let Quattro get away, to his amusement, and defeated his [[Mustached Duelist|own opponent]] with "[[Gimmick Puppet Egg Head]]". Quattro sped off afterwards, with Shark chasing him.<ref name="ep51">{{episode|Yu-Gi-Oh! ZEXAL|51|ref}}</ref> The chase continued into the underground section of the Duel Coaster, with Quattro and Shark both [[Conical Hat Duelist|defeating]] [[Sultan of Spells|opponents]] while taunting one another. Quattro attempted to lure Shark to the [[Duel Field|Magma Field]], which would part Shark at a disadvantage.<ref name="ep53">{{episode|Yu-Gi-Oh! ZEXAL|53|ref}}</ref>

[[File:SharkvQuattro57.png|thumb|200px|right|Quattro vs. Shark]]
However, Shark was prepared to counter the field, "[[Magma Field]]" by using cards such as "[[Plate Salvage]]" and "[[Adapt to Adversity]]". Shark brought out "[[Submersible Carrier Aero Shark]]" on his first turn, inflicting 1200 [[effect damage|damage]] to Quattro before the latter even got a turn. Quattro countered with "[[Number 15: Gimmick Puppet Giant Grinder]]", which Shark countered with "[[Number 32: Shark Drake]]". Quattro was shocked to see this card, not being aware that [[Trey]] gave the card to Shark. He knew that Vetrix and Quinton were planning something, but he didn't know what. Vetrix appears before him, saying that he told Quattro nothing about this, since he may have leaked the plan if he knew. He insisted that everyone had their own role in this - Trey had his, Quinton had his and Quattro is fulfilling his now. Quattro asked what his role is; Vetrix told him that it is to make Shark fall to the darkness of his heart, and told him he's doing quite well so far. Vetrix later revealed that he wanted to use Shark as an assassin who would defeat [[Dr. Faker]]. Quattro is hurt, saying that he, Trey and Quinton did everything for Vetrix, and asked why Shark was chosen as the assassin and not them. Vetrix responded that they all have their role, and Shark fits the role of assassin better than Quattro. Quattro set out to prove Vetrix wrong and continued the Duel. He then managed to Summon "[[Number 40: Gimmick Puppet of Strings]]" and due to "[[String of Destiny]]", he attacked Shark a total of eight times.<ref name="ep57">{{episode|Yu-Gi-Oh! ZEXAL|57|ref}}</ref>

[[File:MiddleChildSyndrome.png|200px|thumb|left|Quattro is hurt by his father's words.]]
Vetrix chided Quattro for being reckless, saying he was always like that and suggested he try to be calm instead, as he can't be trusted. Quattro remembered when his father used to be kind, but after returning, he was only a demon of revenge. However, Quattro said he and his brothers still obediently followed his orders despite this. Shark responded that he didn't care if Vetrix used Quattro - Quattro was still responsible. Quattro believed that if he defeated [[Dr. Faker]], his father would surely return to normal. Quattro told Vetrix he did inhuman things for his sake and yet Vetrix cannot trust him. Vetrix responded he can only trust himself and the [[Barian World]], but Quattro insisted he is not a pawn like his brothers were - he is the Asian Duel Champion. Vetrix then supported Shark during the Duel, insisting that he had a way out as he could think calmly. This hurt Quattro, but Vetrix said he had already fulfilled his role. Quattro attempted a comeback with "[[Number 88: Gimmick Puppet of Leo]]", which would allow him to declare an [[Automatic Win]] on his next turn. Shark finally accepted "Shark Drake" and was able to perform a [[Chaos Xyz Evolution]] to create "[[Number C32: Shark Drake Veiss]]" and defeat Quattro. He apologized to Shark after the Duel, but told him not to blame Vetrix for it and implored Shark to defeat his father and save him. Quattro then disappeared through a portal, adding that Shark should tell his father that his sons will wait for him.<ref name="ep58" />

[[File:IVPortal.png|right|thumb|200px|Quattro vanishes, imploring Shark to save his father.]]

Due to "Gimmick Puppet of Leo" being such a powerful "Number" and his crest being connected to his soul, Quattro fell comatose afterwards<ref name="ep65" /> and was shown sleeping beside his brothers. While talking with a being through a portal, Vetrix called it a shame that he had to sacrifice his sons, but maintained that his plan was going the way it should have been.<ref name="ep60">{{episode|Yu-Gi-Oh! ZEXAL|60|ref}}</ref> During Vetrix's Duel with Kite, he revealed that he merely exploited Quattro alongside his brothers, [[Dextra]] and Shark in order to bolster his "[[Number 69: Heraldry Crest]]" with hatred as he had no emotions to spare.<ref name="e64">{{episode|Yu-Gi-Oh! ZEXAL|64|ref}}</ref> After Vetrix was defeated by Yuma, he released the souls of those he has captured, including those of his sons, who awoke afterwards.<ref name="ep67">{{episode|Yu-Gi-Oh! ZEXAL|67|ref}}</ref> He, his brothers, and his father watched part of the Duel between Yuma and Kite. Then Vetrix told them they would go home and departed through a portal.<ref name="ep72" />

===Yu-Gi-Oh! ZEXAL II===
====Mythyrian Numbers War====
Quattro and his brothers later returned to [[Heartland]] via submarine where they decided it was time to make their move in the ongoing war between the [[Astral World]] and the [[Barian World]].<ref name="ep112">{{episode|Yu-Gi-Oh! ZEXAL|112|ref}}</ref>

After [[Chironex]] poisoned [[Rio Kastle|Rio]] and disappeared in search of Shark, [[Yuma Tsukumo|Yuma]], [[Tori Meadows|Tori]] and [[Trey]] planed to go in search of him, Quattro met up with them in the hospital. Trey asked Quattro to deal with Chironex, while Yuma returned "[[Number 15: Gimmick Puppet Giant Grinder]]", "[[Number 40: Gimmick Puppet of Strings]]", and "[[Number 88: Gimmick Puppet - Destiny Leo]]" to him.[[File:QuattroHelpsShark.png|thumb|left|Quattro comes to aid Shark in a Duel against Chironex.]] Later, Quattro appeared on the roof just as Chironex poisoned Shark, teasingly calling himself Shark's "Number one fan", and challenged Chironex to a Duel. He partnered up with Shark, stating that he was fighting not only as a favor to his brother but for Rio's sake as well. After Chironex reduced Shark to 400 Life Points with "[[Number 4: Stealth Kragen]]", Quattro took the third turn to [[Xyz Summon]] "Giant Grinder" and used it destroy "Stealth Kraken".<ref name="ep114">{{episode|Yu-Gi-Oh! ZEXAL|114|ref}}</ref> As the poison continued to worsen Shark's condition, Quattro Summons "Gimmick Puppet of Strings" to deal massive damage to Chironex, but had its abilities blocked by Chironex's "[[Jelly Bind]]". Working together with Shark, the two were able defeat Chironex and Quattro received the "Stealth Kraken" card.<ref name="ep115">{{episode|Yu-Gi-Oh! ZEXAL|115|ref}}</ref> One night, Quattro called Trey to checked on Yuma and asked if he would be alright after losing [[Astral]], but Trey reassured him that Yuma would be fine.<ref name="ep116">{{episode|Yu-Gi-Oh! ZEXAL|116|ref}}</ref>

Sometime later, Quattro, Trey, and Yuma's friends were speaking in their submarine about the frequent riots that had been breaking out around Heartland. The brothers summarized that the riots was due to the one million "[[Numbers]]" and that the [[Barian]]s had something to do with it. Once [[Quinton]] returned, they learned what happened with Yuma when [[Mr. Heartland]] appeared before them. Mr. Heartland bragged to Quattro and the company how their world and the Barian World were fusing together. As he watched Kite Duel against Mr. Heartland, the "[[Fake Number]]" Quattro took from Chironex affected his body, causing him pain, and was taken by Mr. Heartland.<ref name="ep122">{{episode|Yu-Gi-Oh! ZEXAL|122|ref}}</ref> Once Yuma and Astral returned, Quattro was happy to see him and watched as Yuma and Astral continued the Duel in Kite's place. Afterwards, he congratulated Yuma on his victory, but their situation turned more dire as Quattro and the others saw the large pillar of energy glowing even brighter.<ref name="ep123">{{episode|Yu-Gi-Oh! ZEXAL|123|ref}}</ref>

====Barian Emperor Onslaught====
[[File:Nasch Vs. Quattro.png|thumb|200px|Quattro Duels against [[Reginald Kastle|Nash]] in order to bring back Shark.]]
After [[Mr. Heartland]] was defeated, the Seven Barian Emperors arrived together on Earth in front of [[Yuma Tsukumo|Yuma]]. Quattro was shocked to see [[Reginald Kastle|Shark]] among them, now known as Nash. Yuma was rendered unable to Duel when the Emperor's Key reacted with Nash's Barian Emblem. As the Emperors were about to attack, [[Roku]] and [[Kaze]] arrived, pelting the Emperors with smoke bombs. This allowed Yuma's entire group to escape using Quinton's armored car. Nash ordered a chase, but each of the other Emperors save [[Vector]] were blocked by Yuma's companions and forced to Duel. Nash himself caught up with the car they had used to flee, prompting Quattro to exit the car and stall for time. Quinton asked if he could really do this, commenting that Shark was Quattro's "only true friend". Quattro affirmed that he was the only other person besides Yuma who could get through to Nasch. Quinton gave him "[[Rank-Up-Magic Argent Chaos Force]]", revealing it as the trump card of humanity he had recently completed. As the others sped away, Quattro vowed to do what Yuma would do - reforge the bonds of friendships with a Duel and give Nash a passionate "fanservice". During the Duel, Quattro managed to Summon "[[Number 15: Gimmick Puppet Giant Grinder]], but Nash unveiled his "[[Number 10X]]" card, "[[Number 101: Silent Honor ARK]]". In response, Quattro used "[[Rank-Up-Magic Argent Chaos Force]]" to create "[[Number C15: Gimmick Puppet Giant Hunter]]". He used his new monster to destroy "Silent Honor ARK," enduring pain in the process. Nash initiated a [[Barian's Chaos Draw]] at the same time as each other Emperor.<ref name="ep124">{{episode|Yu-Gi-Oh! ZEXAL|124|ref}}</ref>

This allowed Nash to create "[[Number C101: Silent Honor DARK]]" using "[[Rank-Up-Magic - The Seventh One]]". It absorbed "Giant Hunter", but Quattro survived by defending with "[[Gimmick Puppet Shadow Feeler]]". He was able to recover "Argent Chaos Force", using "[[Banish Reactor]]" and proceeded to use it to create "[[Number C40: Gimmick Puppet of Dark Strings]]". Though this card destroyed "Silent Honor DARK" and even returned Nash to his human form briefly, the effect of "Silent Honor DARK" revived it and recovered Nash's life. Nash urged Quattro to think of him not as a friend, but an enemy he must defeat. Quattro retained his desire to reforge the bonds of friendship until every other human Duelist involved was defeated and their souls sent to the Barian World. Finally giving in to Nash's desire to hate him, Quattro was enraged and accepted that Nash was no longer the person he knew. Nash was pleased and wished to use this opportunity to bury the last link to "Reginald".<ref name="ep125">{{episode|Yu-Gi-Oh! ZEXAL|125|ref}}</ref> [[File:IVsentotheBarianWorld.jpg|thumb|200px|left|Quattro's soul is taken to [[Barian World]].]] Quattro was able to use "[[Triangle Gimmick Box]]" to Summon "[[Number 88: Gimmick Puppet of Leo]]" and Rank it up using "Argent Chaos Force" to "[[Number C88: Gimmick Puppet Disaster Leo]]", his "strongest and final trump card". Planning to use "Disaster Leo" [[Automatic Win]] condition on his [[End Phase]], Quattro's strategy was foiled when Nash stopped it using "[[Overlay Award]]". When Nash commented about losing his humanity, Quattro came to realize something and tried one last effort to bring back Nash to the way he was by attacking him with "Disaster Leo". However, Nash was able to revive "Silent Honor DARK" once more and defeated Quattro. Laying on the ground, Quattro commented that Nash was using him to force himself into a destiny he couldn't escape from. Although he was disappointed, he was unable to change Nash's fate, Quattro said that he enjoyed having another fight with "Reginald" in the end. With a sad smile, his soul was then absorbed into the [[Barian World]], leaving only his [[D-Pad]], Deck and "[[Number]]s" behind.<ref name="ep126">{{episode|Yu-Gi-Oh! ZEXAL|126|ref}}</ref>

Quattro was revived after Nash was defeated by Yuma, appearing in the same spot where Nash defeated him. He, his brothers and Vetrix watched the Duel between Yuma and Astral.<ref name="ep144">{{episode|Yu-Gi-Oh! ZEXAL|144|ref}}</ref> Afterward, Quattro was seen continuing his career as a professional Duelist. He joined Yuma and his friends on the journey to the Astral World upon hearing about its new crisis.<ref name="ep146">{{episode|Yu-Gi-Oh! ZEXAL|146|ref}}</ref>

[[File:CardDarts.jpg|left|200px|thumb|Some of Quattro's "[[Number]]s", being used as darts to choose his next targets.]]
Before Dueling [[Bronk Stone|Bronk]] and [[Caswell Francis|Caswell]], Quattro had obtained at least ten "Numbers". One of them, "[[Number 32: Shark Drake]]", is given to his brother [[Trey]].<ref name="ep33" />

[[File:Number15GimmickPuppetGiantGrinder-JP-Anime-ZX-NC.jpg|right|200px|thumb|"[[Number 15: Gimmick Puppet Giant Grinder]]".]]
Among the others "Numbers" are "[[Number 15: Gimmick Puppet Giant Grinder]]"<ref name="ep33" />, "[[Number 40: Gimmick Puppet of Strings]]"<ref name="ep43" /> and "[[Number 88: Gimmick Puppet of Leo]]".<ref name="ep58" /> After losing to [[Reginald Kastle]], [[Vetrix]] took all of his "Numbers" from him, and they eventually ended up in the [[Sphere Field]]<ref name="ep68">{{episode|Yu-Gi-Oh! ZEXAL|68|ref}}</ref> and were ultimately obtained by [[Yuma Tsukumo|Yuma]].<ref name="ep74">{{episode|Yu-Gi-Oh! ZEXAL|74|ref}}</ref>

When Quattro returned to aid Yuma against the Barians, Yuma allowed him to use his three "Gimmick Puppet" "Numbers" again.<ref name="ep114" /> After Dueling alongside Reginald against [[Chironex]], he obtained "[[Number 4: Stealth Kragen]]"<ref name="ep115" />, but it turned out to be a [[Fake Number|fake]] and was eventually destroyed.<ref name="ep123" />

In his next Duel against [[Nash]], Quattro used "[[Rank-Up-Magic Argent Chaos Force]]" to upgrade his "Gimmick Puppet" "Numbers" into new forms - "[[Number C15: Gimmick Puppet Giant Hunter]]", "[[Number C40: Gimmick Puppet of Dark Strings]]" and "[[Number C88: Gimmick Puppet Disaster Leo]]". Following his defeat by Nash, all of Quattro's "Numbers" were taken by the [[Seven Barian Emperors|Barian Emperor]].<ref name="ep126" />

==Decks==
===Gravekeeper's===
Quattro used to play a '''"[[Gravekeeper's]]" Deck''', based on the cards seen when his Deck "fell" on the floor during the [[National Duel Circuit]].

}}

===Gimmick Puppet===
Quattro uses a '''"[[Gimmick Puppet]]" Deck<ref name="ep53" />''', primarily focused on [[Xyz Summon]]ing his "[[Number]]" [[Monster Card|monsters]] quickly. He usually opts for an [[effect damage]] strategy in the early game, using cards such as "[[Gimmick Puppet Egg Head]]" and "[[Attack Gimmick]]" to do so. Quattro's Deck also features a [[One Turn Kill]] strategy centred around "[[Number 15: Gimmick Puppet Giant Grinder]]" and "[[Gimmick Puppet Princess]]". As he needs Level 8 monsters to Xyz Summon his "Numbers", Quattro uses several cards to easily gather them, such as "[[Gimmick Puppet Des Troy]]" and "[[Junk Puppet]]" in addition to cards such as "[[Level Doubler]]" and "[[Gimmick Puppet Gear Changer]]" to modify Levels. He also utilizes "[[Gimmick Puppet Nightmare]]" and "[[Triangle Gimmick Box]]" to make Xyz Summoning his "[[Number 88: Gimmick Puppet of Leo]]" easier as it requires three Level 8 monsters. Just prior to his Duel with [[Nash]], Quattro acquires "[[Rank-Up-Magic Argent Chaos Force]]", giving him access to "[[Number C]]" monsters.
