Vetrix Family

The Vetrix Family, known as the Tron Family in Japanese version, is a family/organization appearing in the Yu-Gi-Oh! ZEXAL anime, led by Vetrix. Other members are the three brothers, Trey, Quattro, and Quinton. Their true surname is "Arclight".

Their attire is very medieval in design and they have crests on their hands (with the exception of Quinton, whose crest is on his forehead), as well as a tattoo-like Duel Gazer marks used instead of a mechanical one, just like Kite Tenjo and the people working under Dr. Faker.

They have knowledge of "Numbers" and collect them to get their revenge on Dr, Faker. However, they had no knowledge about Chaos Xyz Evolution until Yuma played his own "Chaos Number."

History
The three brothers lived a happy and peaceful life with their father, and they had a dog. Byron Arclight, the father, became involved in Dr. Faker's experiments, allowing his oldest son, Chris to accompany them in the lab.

Later, they hired Kazuma Tsukumo to help them with their research and guide them to some ruins. Byron and Kazuma bonded over their respective families and became friends. When they reached their destination, Faker betrayed them both, sending them to another dimension as sacrifices to open The Door. Though Faker believed Byron to be dead, he eventually returned, with his form warped into that of a child even younger than his youngest son. Swearing revenge against Faker, he took the name "Vetrix", while Chris became known as "Quinton". To initiate Vetrix's machination, Quattro was ordered to duel Rio Kastle. He activated 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 inferno and hospitalized.

Yu-Gi-Oh! ZEXAL
The Vetrix Family's scheme involved Shark coming to their side, and the "Numbers" in some way. As the second part of their scheme, they needed Shark to participate in the World Duel Carnival. As ordered by Vetrix, Quattro made sure he did, by intentionally bringing up Shark's past, and telling him how he purposely set his Deck on the pot to fall, and caused his sister's accident. By doing so, he enraged Shark, thus giving him a reason to want to be in the World Duel Carnival, and making him want revenge against Quattro, who confirmed he would be participating in the World Duel Carnival as well.

The next step in their plan, involved Trey giving Shark "Number 32: Shark Drake", which he succeeded in doing. However, the "Number" could not possess Shark, making Trey speculate that the gambit was not fully successful, but Vetrix said that was not the case, because as long as there was even the smallest of darkness in human hearts, it will expand without them realizing.

The next step, was Quinton taking control of Hart Tenjo through his crest, and taking him to an abandoned gallery, where Vetrix begins a ritual to extract the young boy's powers. In order to ensure the ritual completes, Quinton sends Trey and Quattro to Duel Yuma Tsukumo and Kite Tenjo. The plan however fails, as Hart was able to transfer his remaining power to Kite, at the same time forcing the ritual to end before it was complete. Despite this, Vetrix was able to obtain most of Hart's power as he creates a small energy ball.

They learned Yuma possesses the "Original Number", and has now become a target as well. Also, Vetrix and Quinton recognized Yuma's surname "Tsukumo" and realized that he is Kazuma Tsukumo's son.

The next step involved Vetrix giving Trey new powers so he could defeat Yuma in a Duel. Despite Trey having failed and giving his "Numbers" away to Yuma, Vetrix did not seem to care, and was worried for Trey, comforting him. He then decided to take revenge on Yuma.

After Trey became comatose, the remainder of the Vetrix Family appeared at the World Duel Carnival. When they set off in their Duel Coaster, Quinton and Quattro each had a Duel. Vetrix's does not Duel, but he observed Yuma Tsukumo's Duel against the Fallguys that Quinton had hired to see Yuma's "true power". He was shocked to find that Yuma, with the assistance of Anna Kaboom and Nistro, had beaten the Fallguys.

After the Vetrix Family members cleared the Duel coaster stages, they eliminated what was left of the remaining finalists until there were only 8 left, and then could duel one-on-one with a certain person. Vetrix was lured by Dextra to the Jungle Field and had a difficult fight against her butterfly combo. He came close to losing if it were not for his "Number 8: Heraldic King Genom-Heritage" taking advantage of Dextra's "Photon Butterfly Assassin's" name and abilities as well as turning Dextra's own combo against her. After Vetrix defeated Dextra, he decided to erase all her memories of Kite before taking his leave and telling Yuma that he would eat his heart next.

Later, Quinton and Kite arrived at the Space Field, and started their Duel. Quinton summoned his "Number 9: Dyson Sphere" in the first turn, though he kept it hidden from the field. After Kite Summoned "Galaxy-Eyes Photon Dragon", Quinton decided to reveal his monster as well as gaining a full advantage of the Duel since "Dyson Sphere" cannot be attacked as well as being able to launch direct attacks thanks to Photon Dragon having a higher ATK than "Dyson Sphere". However, Kite decides to wager it all with a card that Quinton did not know about, which he received from his father, to Summon "Neo Galaxy-Eyes Photon Dragon" and win the Duel. After the Duel, Quinton departed but left "Dyson Sphere" for Kite and was later seen entering Trey's room and his crest disappearing, causing him to collapse on Trey's bed and saying that they should rest together.

Quattro lures Shark to Duel him at "Magma Ocean" where his water deck is supposedly going to have a disadvantage. However Shark managed to negate the effects of the Duel Field with the help of his Trap Card, "Adapting to Adversity". During their Duel, they each inflicted massive damage with their Xyz monsters. Though after Shark summons "Number 32: Shark Drake", Quattro is startled by Shark possessing a Number and how Vetrix did not tell him a few parts of his plan. Also during the Duel, Vetrix started to turn his back on Quattro in favor of Shark, and said that Quattro had already done his part. Determined to win, Quattro decides to summon his ultimate Number, "Number 88: Gimmick Puppet of Leo", which would automatically win the Duel on his next turn. However, Shark decides to accept Shark Drake, and manages to Chaos Xyz Summon his new Chaos Number "Number C32: Shark Drake Veiss" to weaken and destroy Destiny Leo, and win him the Duel. After the Duel, Quattro apologizes to Shark and tells him the truth about what happened between him and Shark's sister. He also entrusts the task of defeating and saving their father to Shark before disappearing.

While conversing with a being through a portal, Vetrix called it a shame that he had to sacrifice his sons, but maintained that his machination was close to completion. During Vetrix's duel against Kite, he reveals that he merely exploited his progeny in order to bolster his summoning of "Number 69: Heraldry God - Coat of Arms" with hatred and rage as he had no emotions to spare. He later discloses to Yuma that the crests of Trey, Quattro, and Quinton come with a heavy penalty - they are directly connected to the soul of their wielder in exchange for power. Should they be defeated in a duel while wielding powerful "Numbers", their souls will become debilitated and they are rendered comatose afterwards. After Vetrix was defeated by Yuma, he eventually releases the souls of those he has captured, including his comatose sons, and the three brothers are seen awakening after these events.

After Yuma, Shark and Kite defeated a Barian-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 pleads with Vetrix to abandon his revenge, while Faker blamed himself, hoping he would not 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 crimes and saying "good-bye, my friend" before vanishing again. In this instance, his crest was blue as opposed to pink. He and his sons watched part of the Duel between Yuma and Kite, then Vetrix told them they would go home now and they departed through a portal.

A discussion between Durbe, Alit, Misael, and Gilag reveals they rescued Vetrix, granted him the abilities of the Barian World and returned him to his own world and requested he collect the Numbers and destroy the Astral World as compensation for their altruism.

Obtained Numbers
The Vetrix Family uses Quattro to collect the "Number" cards from Duelists who are entering the World Duel Carnival. The list shown is of the known "Numbers" which are obtained, but it is known that Quattro have at least obtained ten total around the time when he Dueled Bronk Stone and Caswell. Vetrix can extract "Numbers" from their owners by absorbing the cards through his crest. This is the means by which he obtained 15 cards from Kite Tenjo, from which only five are known by name.

The "Numbers" the family possesses cannot be taken forcefully (with the exception of the Sphere Field) after losing a Duel, thanks to their crests. The only way a "Number" switches ownership would be if the current owner forfeits or hands the card to a new owner.
