Vetrix Vetrix , known as Tron in the Japanese and Italian versions and born Byron Arclight , is a character appearing in the " Yu - Gi - Oh ! ZEXAL " anime . He appears as the secondary antagonist during the World Duel Carnival arc . Vetrix was formerly involved with Dr . Faker ' s business , and has sworn to take revenge alongside his sons : Trey , Quattro and Quinton . After Trey was defeated by Yuma Tsukumo , he made plans to target him as well since he possessed the " Original Number " . Though his appearance is that of a child younger than the rest of the Vetrix Family , he is their father . He was betrayed by Dr . Faker , who used him and Kazuma Tsukumo as sacrifices to open the door to another dimension . When he returned , his form was mutated into that of a child . Design . Appearance . Vetrix appears as a young boy with blond hair , which some of it is braided resting over his right shoulder . He is outfitted in light greenish clothing and seems to be as tall as Hart Tenjo . He carries his Deck in a Deck box which is attached to the left side of his belt . He also wears a metallic crowned mask that reveals parts of his face . Unmasked , the right side of Vetrix ' s face is disfigured by a strange , dark void shown to be slowly consuming it . His forehead also has markings on it similar to those on the forehead of " " . Like other members of Vetrix Family , Vetrix also possesses a Barian - inspired Crest that appears on his right hand . When his powers are at their peak , his crest appears upon the crown of his head . Personality . Byron Arclight was first shown to be a calm and gentle person who valued friends and family . He helped Dr . Faker with his research out of respect , despite not knowing what his goals are and allowed his eldest son to help . He quickly became friends with Kazuma Tsukumo as they bond over their sons , and wanted Kazuma to let him fall into the other dimension so that Kazuma could save himself when Dr . Faker betrayed them . After falling into the other dimension , he became obsessed with taking revenge against Faker , going as far as hurting others to reach that goal . However , he continues to respect Kazuma and his ability to make friends , but he also notes that it was the reason for his disappearance . As Vetrix , he acts just like a child , enjoying cartoons and playing video games to the point where he bursts out in fits of laughter and acts like a regular child in public events . When not watching cartoons or when not in public , his personality is similar to his original , when he is talking to Trey , Quattro , and Quinton showcasing how he is the leader of the group . As he is their father , he is the most respected out of his family , as when Quattro talked back to him , Quinton stood up for him and scolded Quattro . Vetrix is close to Quinton , as they are seen talking to each other often , and care a great deal about Trey . While Trey was Dueling Yuma Tsukumo , he was very confident that he would win due to the powers and cards he gave him , and was not at all concerned about Trey ' s safety during the Duel , even after being talked to by a worried Quinton . After Trey was defeated and nearly killed , Vetrix stayed at his bedside , worried about him , and not seeming to care about him giving away the 2 " Number " cards he had to Yuma . His relationship with Quattro is strained due to his recklessness , but Vetrix does praise his efforts in his plans . As Vetrix becomes closer to getting his revenge , it appears he does not care about his family anymore from the moment he returned to Earth . He sees his family as worthless and only as pawns who had different roles to further aid his machinations . Though an important reason for his revenge on Faker was not just for sending him through the rift between dimensions , but for having his body torn apart at by the galaxy which has replaced the left side of it , as well as having his memories of his beloved family being taken from him . In his reminisces , he is seen to care deeply for his family despite his change in personality . Vetrix also appears to be cruel and merciless like Quattro while Dueling , as shown during his Duel with Dextra when he defeated her using her own cards against her and even used his " " to copy her Ace monster ' s name . Knowing Kite is very important to Dextra , he erased all her memories about him after winning the Duel simply to make her suffer . He also mocks her feelings cruelly stating that her love for Kite had " a bad taste " . Vetrix claims that he has no true emotions , even using the rage and hate provided through his sons , Shark and his own opponents to bolster the summoning of " " , which requires rage and hate to control . Vetrix was at first interested in Yuma after knowing he was the son of Kazuma , and targeted him without much concern or worry , evidenced by how he was confident Trey would win over win due to the powerful cards he gave him . When the opposite occurred , Vetrix became much more interested in Yuma and devised various methods to attack him mostly out of interest in his power . As Yuma manages to thwart his schemes from time to time , Vetrix develops noticeable rage and hatred towards Yuma , to the point that he shouts his name and calls him " an unsightly boy " . This goes to the point that he has stated he will make him suffer . However , he seemed to have a change of heart when Yuma attempted to save him from the " Sphere Field Cannon " . Before he was absorbed , he released the souls he captured and thanked Yuma for trying to rescue him despite his transgressions . Vetrix later rescues Dr . Faker , Kite , and Yuma from falling into a chasm at the collapsing Sphere Field chamber , showing that he has forgiven Faker and given up his plans for revenge , returning to his original personality . Abilities . Upon returning from the Barian World , Vetrix is granted many powers from the Barian race , including the ability to create Overlay Networks to teleport himself or his sons through his crest . He can also transfer some of his power to another and increase their abilities . After Vetrix enhanced his own powers by taking most of Hart Tenjo ' s Barian power ( even though the ritual was canceled before it was finished ) , he demonstates his newly acquired power by channeling it into a small , but expanding destructive ball of energy . He can also see Astral and communicate with him due to the power he managed to extract from Hart . Vetrix is capable of manipulating the augmented reality system with his Barian powers , as shown during his Duel with Dextra and when he also restrain Yuma with chains from the Barian World . He is also able to manipulate the memories of others , with which he can either steal from those he defeats like Dextra ' s love for Kiteand even modify as he changed Shark ' s memories to make it appear that Yuma and Dr . Faker were responsible for what happened to his sister instead of Quattro . During his Duel with Kite Tenjo , Vetrix revealed that the ritual used to steal Hart ' s powers also allows Vetrix to be physically connected with Hart , by revealing an AR vision of his face . During that time he left a portion of his soul within Hart ' s consciousness , which allows him to inflict pain onto him when he wishes and use him as a human shield against Kite . This soul is represented in the consciousness world as a Dark Dragon immune to normal attacks . If this dragon is slain , Vetrix ' s control fades and he suffers a psychic backlash . In addition , he was also shown to be able to utilize the Duel Anchor like his sons , although his is a much darker shade and is wrapped in a dark aura . He is also capable of absorbing " Numbers " after defeating his opponents . Vetrix can envelop himself in red light , identical to that of Yuma before he merges with Astral using ZEXAL . This enables him to travel quickly . Using what remained of his powers , Vetrix was able to erect a barrier between the arena used by Yuma and Nash and the merged Barian World and Earth . Etymology . The word Tron can potentially be derived from θρóνος thronos , meaning ' throne ' and in Polish and Swedish , the word Tron means Throne as well . This may also be to do with the fact that he sat on a throne during the World Duel Carnival preliminaries , watching cartoons while his sons gathered Heart Piece s . The nickname " Cinderella Boy " given to Vetrix by Mr . Heartland is most likely derived from the fact that he showed up in the World Duel Carnival unknown to anyone while successfully making his way up to the finals . This can be compared to Cinderella showing up at the ball and shocking everyone with her beauty . Prior to that , no one had known she existed . Biography . History . Byron Arclight lived in peace with his three sons , and was a researcher . He gave his son Michael a " Duel Monsters " card - " Chronomaly Aztec Mask Golem " . He eventually became involved with Dr . Faker ' s experiments and allowed his son Chris to accompany and help them in the lab . One of these experiments from the development of the Sphere Field . In addition , they were attempting to find the door that would lead to parallel worlds . Byron suggested they ask Kazuma Tsukumo for help , an adventurer who was also searching for the same door . Kazuma agreed to help them , and after examining their theory , he told them what was wrong with it . They had been operating under the assumption that were twenty - one passage points . By analyzing that data , they could determine where the door would appear next . Kazuma revealed that there were actually twenty - three passage points , something he had determined while exploring . With that new data , they determined where they needed to go . Byron had Chris stay behind , and he goes with Kazuma and Faker to travel to the destination . On the way , Byron and Kazuma bonded over their sons , who loved Dueling , with Byron saying that Faker also has two sons . When they arrived , Kazuma saved Faker from being crushed by a boulder trap in the temple . They reached a dead end , with Faker remaining slightly behind them , the two began to glow red and Faker reads the hieroglyphs below their feet - " when two souls are offered up , the door will open " . Faker told them he would find the door to the parallel dimensions at any cost . Kazuma asked if Byron and Faker weren ' t close friends and Faker responded that if Byron is really his friend , he should be happy to be sacrificed . Faker told Byron that average people like him could hope for no more than that . As Byron and Kazuma fell through the portal , Byron swore revenge against Faker . While wandering through the alternate dimension , he nearly gave up hope many times . He recalled Kazuma ' s talk of friendship and of never giving up , though he considered Faker ' s betrayal as proof of the uselessness of friendship , but found Kazuma ' s mantra of never giving up to be inspiring . Sustained by the hope of attaining revenge , he survived through his own will and with the help of the Barian World . While trapped there , he was rescued by a group of Barian s , one of them whom granted him Barian power in exchange for him agreeing to help collect the " Number s " and destroy the Astral World , as beings from the Barian World could not interact with it themselves . He eventually returned to Earth , but his form was mutated into that of a child and he took the alias " Vetrix " . He began to devise a machination per his deal with the being from the Barian World , also deciding to use the opportunity to take revenge on Faker as the latter believed him to be dead . He granted each of his sons a crest , which imbued them with great powers . However , they were directly tied to their souls , so should they lose a Duel while wielding a powerful " Number " , their souls will be exhausted and they will fall comatose . As part of the plan , Vetrix instructed Quattro to Duel Rio Kastle . He played a card given to him by Vetrix called " Flaming Hell Blessing " , which set the building on fire . Quattro carried Rio to safety , but she was critically injured in the blaze and Quattro himself gained a scar on his face . Yu - Gi - Oh ! ZEXAL . World Duel Carnival Preliminaries . Vetrix instructed Quattro to ensure that Shark participated in the World Duel Carnival . During the second morning of the WDC , Vetrix awoke to Quattro arguing with Quinton about Quattro ' s methods . With Vetrix backed up by Trey and Quinton , Quattro backed down . As part of his plan , Trey was instructed to give Shark " " . After Quattro and Trey left to complete their missions , Vetrix told Quinton to ensure that no matter what , Dr . Faker must not find out that he is alive since he believes that he is deceased . Trey returned to Vetrix in order to inform him of his success in handing Reginald Kastle " Shark Drake " , which Vetrix congratulated him on fulfilling his orders as he always does . After saying modesty was one of Trey ' s virtues , Trey was worried since the " Number " did not possess Shark , but Vetrix tells him that its darkness will sleep in Shark ' s heart and slowly grow be released one day . Vetrix ordered Quinton to kidnap Hart Tenjo in order to further his plans to defeat Dr . Faker . After Quinton took Hart via the use of his crest , he transported him to an abandoned gallery where Vetrix and his sons awaited him . They then began the ritual which caused several tentacles to wrap around Hart , which in turn then passed his memories and powers onto Vetrix , allowing him to see the Astral World . While this was taking place , Yuma Tsukumo and Kite Tenjo managed to enter the gallery . To prevent them from stopping the ritual , Quinton sent Trey and Quattro to Duel them in order to prevent them from reaching Vetrix in time for the ritual to finish . During the ritual , Vetrix was able to access Hart ' s memories . He first saw the memory in which the Tenjo brothers lived peacefully before meeting Mr . Heartland . As Trey and Quattro ' s Tag Duel against Yuma and Kite continued , Vetrix ' s ritual gets interrupted when Hart , wanting to be one to save his brother instead of the opposite , transferred his remaining powers to Kite . Vetrix was still able obtain most of Hart ' s powers , gaining the ability to produce a small but powerful energy ball . Furthermore after Vetrix tested his new obtained power , he learned from Quinton that Yuma Tsukumo possesses the " Original Number " . However , because of Yuma ' s surname , Vetrix wonders if he is the son of Kazuma Tsukumo , which Quinton answers as correct , surprising him . When Trey wishes to met Yuma , Vetrix allowed him and reassured Quinton that Trey will return to them because he was a " kind person " . At Trey ' s request , Vetrix performed a ritual on him , similar to the one he performed with Hart , transferring some of his power into Trey ' s crest , which Vetrix called the powers equivalent to the pain that Trey had felt in his life . In addition , he gave him two new cards - " " and " Final Prophecy " . Vetrix told him that the former card would put a great strain on him both physically and mentally and that the latter card would ensure that both players do not walk away unharmed . During Trey ' s Duel with Yuma , Vetrix alongside Quinton observed the Duel from a balcony , where Quinton felt nervous about whether or not Trey can win , but Vetrix reassured Quinton that he will with the power which he granted him . Vetrix was revealed to have not only awarded Trey a more powerful crest , with powers which can physically harm people , but also allowed Trey to manifest armor as well as capture and crush Astral . After Yuma managed to retrieve his old personality from Trey ' s crest , he managed to make a come back with " " , which Trey responded to by Xyz Summon ing " Atlandis " . This " Number " was revealed to be extremely strong , even causing damage outside of the Duel and AR Vision , and " Final Prophecy " opened the door to the Barian World when it was played . Quinton warned Vetrix that Trey may be in trouble , but Vetrix responded with laughter . When Yuma defeated Trey , Vetrix was shocked that Trey lost the Duel . After Trey returned to the hotel where his family was staying , Vetrix comforts him at his bedside . World Duel Carnival Finals . Later , Quattro implored that Vetrix give him new powers so he could defeat Yuma . Vetrix responded that he was disappointed in both Trey and Quattro . Quattro angrily replied that Trey fought against the " Original Number " for Vetrix and ended up comatose . Vetrix responded that what he wants is 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 . At the WDC Finals party , Vetrix revealed himself while interrupting Mr . Heartland ' s speech , who he called " old man " and told him that he would crush him . Vetrix then playfully told them how much he likes cake and called down to Yuma as " big brother " and told him that they will meet in the finals . Before leaving , he stared directly at Astral and laughed , and was later seen playing a video game while Quinton conducted business with the Triad of Terror . The next day , Vetrix boarded the Duel Coaster with the rest of the finalists and witnessed Quinton defeat an opponent in one turn and said he expected no less of him . He also saw that Shark and Quattro ' s Duels as well and comment how relentless they were . Later on , Vetrix watched the Triad of Terror cornering Yuma and stated that he wanted to see how much power Yuma had . He stated he would give the Triad of Terror as much money as they desired if they showed him Yuma ' s power . When the Triad of Terror were defeated after Anna Kaboom and Nistro allied with Yuma , Vetrix remarked that Yuma ' s true power was that of his bond with his friends . The Duel Coaster moved into the underground section , with Vetrix using the power of his crest to check the cards Set at Spell and Trap Points , so he would know whether to avoid them or not . He defeated Lord Percius , Pepe Perez and Count Crazy Fang ( all of whom had over 5000 Life Points at the time ) simultaneously through unspecified means . When Quinton attempted a counterattack against Yuma for damaging his Life Points , Vetrix called him off , saying he should leave Yuma alone for the moment . Dextra and Kite both approached Vetrix from behind , with Kite changing lanes when Dextra threatened him . Vetrix and Dextra stopped their Duel Coasters at the " Jungle Field " arena . Due to the " Jungle Field " , each player was forced to Set a monster from their hand each turn , or lose 1000 Life Points . Dextra managed to use a powerful combo that forced Vetrix ' s monsters to attack , destroy them and inflict 1500 damage to the owner of a monster that is destroyed , thus reducing Vetrix ' s Life Points to a mere 100 . He was able to turn Dextra ' s own effects against her through " " , while mocking her feelings for Kite and attempts to steal her memories of him . Yuma intervened and brought Dextra back to her senses to continue the Duel . However , Vetrix disabled Dextra ' s counter and defeated her , robbing her of her memories of Kite , cruelly saying that they have a " bad taste " . He then teleported away while warning Yuma that he will target his heart next . Vetrix later placed a hologram of himself into the augmented reality of the " Magma Field " to watch Quattro and Shark ' s Duel . When Shark Summoned " " , Quattro was surprised , not knowing that Vetrix and Quinton ' s plan was to have Trey give that card to Shark . Vetrix responded that he told Quattro nothing as he may have leaked the plan and said that everyone has their own role in this ; Quattro ' s was to make Shark succumb to the darkness of his heart . He complemented Quattro on his counters , but told him that he intended to make Shark an assassin to defeat Dr . Faker . Quattro was hurt , saying that he , Trey and and Quinton did everything for Vetrix - why would he chose Shark as the assassin instead . Vetrix again said that everyone had their role and Shark fits the role of assassin more than Quattro , angering him . After Quattro ' s brutal assault on Shark , Yuma urged them to stop the meaningless fighting , but Vetrix used his crest to chain him . Vetrix then tried to convince Yuma to get revenge on Dr . Faker for what he had done to Kazuma . Vetrix told Astral he could not free Yuma as the chains used the power of the Barian World , which the powers of the Astral World cannot affect . Vetrix went on to tell Quattro that he can ' t be trusted due to his recklessness and urged him to be calm . Quattro was hurt , saying that Vetrix used to be a kind person before he disappeared . Quattro wanted to defeat Dr . Faker , as he believed that Vetrix would return to normal if he did . Quattro said he did inhuman things for Vetrix ' s sake , yet he can ' t be trusted . Vetrix responded he can only trust what saved him - himself and the Barian World . Quattro successfully Summoned " " , with Shark almost losing hope . Vetrix advised him to be calm and told him he could win by accepting " Shark Drake " , which caused Shark to give in and create " " , defeating Quattro . Mocking Yuma , Vetrix told Shark that now they are friends as well and wondered how Yuma ' s " kattobingu " would take him . Vetrix later conversed with his benefactors in the Barian World through a portal and assured them that his plan was going smoothly . He claimed all the " Numbers " would be his by tomorrow , but he had to sacrifice Trey , Quattro and Quinton , and added that they did a good job , as he had expected of his sons . He then left and ambushed Shark , using his crest ' s power to gain control over the " Number " merged with his soul . He also gave him " Heraldry Catastrophe " to use in the upcoming Duel against Yuma . Vetrix utilized his control over Shark during his Duel with Yuma , where he made Shark believe that Yuma alongside Dr . Faker were the ones responsible for his sister ' s injuries . As Shark began to win , Vetrix became excited as his plan was near complete . After Yuma took control of " Shark Drake Veiss " with " Rivals Unite " , he began to fall under the influence of " Shark Drake Veiss " , while Shark was freed from it . Vetrix appeared before Shark and told him that the only way to free Yuma would be to activate " Heraldry Catastrophe " . Despite this , Shark managed to rescue Yuma at the cost of his own Life Points with " Underwater Snow Prison " , causing Yuma to win . This outraged Vetrix , causing him to smash the observation boxes windows out of anger and he vows to finish Yuma off , nice and slowly . When Kite and Vetrix began their Duel , Vetrix noticed how Photon Transformation has been negatively affecting Kite ' s body ; therefore he played up to it and attempts to destroy " Galaxy - Eyes Photon Dragon " to harm Kite , but failed . Kite attempted to perform a OTK on Vetrix with his " Galaxy - Eyes " , Quinton ' s " " and " Photon Wing " , but failed at the hands of Vetrix ' s " Heraldry Change " Trap Card . Vetrix then took his mask off , revealing an AR version of Hart ' s face . When Vetrix pinched it , it caused Hart immense pain . Kite attempted to leave the Duel in order to assist Hart , but Vetrix used a Duel Anchor to stop him . Vetrix then brought out " Genom - Heritage " , which was able to destroy " Dyson Sphere " and reduce Kite to 1200 Life Points , and then mockingly called Kite " brother " . As the Duel continued , Vetrix continued to tease Kite with his brother ' s life on the line , but Kite continued to attack . To destroy Vetrix ' s link with Hart , Yuma invaded Heartland Tower and managed to enter Hart ' s mind to find Vetrix appearing in the form of a dragon , which Yuma managed to destroy with " " . After this , Hart was freed from Vetrix ' s control , causing Vetrix ' s Hart facade to begin to fade , and therefore he put his mask back on to conceal his identity . He then managed to avoid being defeated by Kite ' s " Neo Galaxy - Eyes Photon Dragon " and in response Xyz Summoned his " " , which successfully defeated Kite . Vetrix then attempted to continue to assault Kite , despite his Life Points being at 0 , but Hart interfered , protecting Kite from the attack of " Heraldry Crest " attack . After being declared the winner , he absorbed Kite ' s " Numbers " and departed through a portal , leaving an incapacitated Kite on the Duel Tower . Vetrix advanced to the final match against Yuma . At the top of the tower , Faker deployed the Sphere Field , Vetrix seemed pleased that Faker had completed it . This device would allow Faker to gather the energy of the " Numbers " Vetrix and Yuma would wield , as its effect allowed " Numbers " to be easily Summoned . Yuma confronted Vetrix about his sons ' fates , and he revealed the price they paid by wielding crests , while telling Yuma how it was Kazuma whose words inspired him to survive . He queried Yuma on why he himself did not want revenge on Faker . Yuma insisted his father would not want that , but Vetrix suggested that perhaps his father ' s own plans of revenge had already begun - the appearance of Astral in this world . The Duel began , with " Sphere Field " enabling both players to Special Summon random " Numbers " from their Extra Deck s by using two monsters of the same Level from their hand s as Overlay Units . Vetrix ' s " " was destroyed by Yuma ' s " " . Vetrix responded by bringing out three " Numbers " in a single turn - " " , " " and " Genon - Heritage " . Yuma survived via the effect of " Armor Ninja " and " Half Guard " and was able to match Vetrix ' s move by Summoning " " , " " and " Utopia " . Yuma managed to destroy all of Vetrix ' s " Numbers " , putting him at a disadvantage . However , Vetrix made a comeback by Summoning " Heraldry Crest " which absorbed the effects of all of Yuma ' s " Numbers " and reduced him to 500 Life Points . Vetrix then took his mask off and revealed to Yuma that half of his face resembles a black hole or galaxy , shocking Yuma , Dr . Faker , Mr . Heartland and the audience . The audience however believed was merely part of the AR holograms , but Yuma ' s friends also realized that it wasn ' t . Yuma performed a Chaos Xyz Evolution and Summoned " " , also equipping it with " ZW - Lightning Blade " using the power of ZEXAL . The effect of " Heraldry Crest " negated even this attack , but Yuma survived with the effect of " Lightning Blade " . Yuma narrowly survived Vetrix ' s next attack by using " Half Unbreak " , and proceeded to use the power of ZEXAL again to perform the " Final Shining Draw " and equip " Utopia Ray " with " ZW - Tornado Bringer " . Vetrix evaded this move with " Heraldry Burst " . Yuma was able to overlay his two " ZW - " monsters to Xyz Summon " ZW - Leo Arms " , whose effect negated those of " Heraldry Crest " and boosted the ATK of " Utopia Ray " enough to defeat Vetrix . Faker used the Sphere Field to absorb the " Numbers " of both Duelists , while the Duelists themselves were nearly absorbed as well . Yuma wielded " Lightning Blade " with his own hands and saved Vetrix by anchoring them to the edge of the Sphere Field , much like Kazuma had in the past . Vetrix was confused as to why Yuma rescued him , Yuma insisted that everybody can change , and that his family needed him and that having Dueled him , he now considered Vetrix a friend . Feeling remorseful for his transgressions , Vetrix released the souls and memories of his victims , including Trey , Quattro and Quinton ' s . He insisted he could not live as Yuma and Kazuma had though and let go of Yuma ' s hand , thanking him for what he had done . He was then absorbed into the Sphere Field ' s core . After Yuma , Shark and Kite defeated Vector , who possessed Dr . Faker , the building began to collapse around them , causing Dr . Faker to fall . Kite managed to grab hold of him , but fell himself , attaching his Duel Anchor to Yuma in an attempt to get them back up . As Yuma struggled to keep the two from falling , Vetrix appeared behind them , agreeing with Faker ' s statement that Faker had committed " many sins " . Yuma pleaded with Vetrix to abandon his revenge , while Faker blamed himself , hoping he wouldn ' t hurt Kite . Vetrix remarked that this is the " last of his power " and fired his crest towards them , apparently causing them to fall . He instead transported them to the outskirts of Heartland , forgiving Faker for his actions and saying " good - bye , my friend " before vanishing again . In this instance , his crest was blue as opposed to pink . Later , Vetrix and his sons watched part of the Duel between Yuma and Kite , commenting how " remarkable " Kazuma ' s son was . Vetrix told them they would go home now and they departed through a portal . Yu - Gi - Oh ! ZEXAL II . Sometime later , Trey revealed that Vetrix was able to divide and share his crest powers with his sons , harnessed inside bracelets Quinton designed , so they could assist Yuma and friends in the war between the Astral World and the Barian World . During the Duel between Yuma and Nash , the Astral and Barian Worlds were close to colliding and destroying both . Vetrix appeared in the Barian World ( now fully fused with Earth ) , while Kazuma appeared in the Astral World . Kazuma thanked Vetrix , saying that his sons had helped Yuma grow into a fine young man . Vetrix thanked him in turn , as Yuma helped him get his family back . Vetrix determined they had to find a way to stabilize the worlds long enough for the Duel to come to its conclusion . Kazuma agreed , and the two entered energy forms of the same colors used by Yuma and Astral before using ZEXAL . They used the last of their powers to become barriers between the arena and the two colliding worlds . Vetrix ' s crest shined out ( now pink once again ) , while an image of the Emperor ' s Key shined out for Kazuma . After the Duel ' s end , Vetrix and Kazuma reappeared , with Vetrix stating the Earth had begun to drift away from the Astral World . Kazuma thanked Vetrix for his help , calling him " old friend " . Vetrix mused he had repaid some of the debt from his earlier actions before vanishing . Some time after Yuma ' s and Astral ' s Duel , he started working together with a revived Quinton , Kite and Dr . Faker to research parallel worlds again . Upon hearing about the Astral World ' s crisis , Vetrix joined Yuma and his friends on the journey there . Number Hunting . Vetrix acquired " " and " " . The latter monster is his most powerful and could only be called forth by intensifying negative emotions in others , which Vetrix achieved through the manipulations of his sons and their targets . Vetrix also owned " " , which he gave to Trey alongside " Final Prophecy " to use against Yuma Tsukumo . After defeating Kite Tenjo , Vetrix acquired all of his " Numbers " , among them " " , " " , " " , " " and " " . He also took Quattro ' s " Numbers " from him after that son ' s loss to Reginald Kastle . These included " " , " " and " " . He himself lost all of these to Dr . Faker ' s Sphere Field after losing to Yuma and all of the cards were eventually obtained by Yuma . Deck . Vetrix plays a " Heraldic " Deck , composed of cards focused on control and manipulation , including the " Heraldic Beast s " and a line - up of " Heraldry " Spell / Trap Card s . His main strategy involves swarm tactics through cards such as " Heraldic Beast Eale " and " Heraldry Reborn " so he can easily Xyz Summon his " Number " monsters . Several of his " Heraldic Beasts " also generate card advantages by banish ing themselves from his Graveyard . Vetrix often gives his pawns some strong cards which also have terrifying side effects such as opening up a portal to the Barian World or cause real damage outside of an Augmented Reality Duel .
