Supreme King Dragon Zarc (覇王竜ズァーク, Haōryū Zāku) is a character in Yu-Gi-Oh! ARC-V anime series. He is the fused form between Zarc and the four dragons, which was said to have once destroyed the world.

Appearance
So far the silhouette of this creature revealed to be sharing mixed traits of the Four Heavenly Dragons and Zarc (mostly the green highlights). Also massive in size, with a pair of large stretched wings and bright glowing yellow eyes.

After he revived by fusing all of his reincarnations, Zarc takes Yūya's form but monstrous that resembles a mixture between a dragon-man and a demon. His body turns grey and become bulkier with number of spikes prostrating from his shoulders, arms, and ankles while his eyes turn bright yellow. His face become veiny and his ears are replaced by wing-like appendages. In this form, he no longer wears Yūya's shirt or rollerblades and has a large pair of black demonic wings on his back.

Personality
Supreme King Dragon Zarc has an intense desire to become the strongest, and after being corrupted by said power, he believes that he rivals God in terms of pure strength. As he was born from the fusion of the four dragons who are enraged to be used as fighting tools to fulfil people's demands, he also seems to bear deep hatred for humans and deems them responsible for his birth, stating that their lust for power and destruction has helped him attain greater power. Following this hatred, he looks down on humans, only seeing them as a mere prey and continuously calls them a foolish being.

History
Before his birth, the Supreme King Dragon was originally four dragons: "Odd-Eyes Dragon", "Dark Rebellion Xyz Dragon", "Clear Wing Synchro Dragon", and "Starve Venom Fusion Dragon" who belonged to a Duelist champion named Zarc in Original Dimension. As he continued duelling violently following the audience's demands, the four dragons became enraged for being used as tools for fighting simply to fulfil their desire, and this anger also influenced Zarc who was able to hear and communicate with his dragons, eventually driving the Duelist insane. One day, in a Duel champion, Zarc decided to destroy the whole world, allowing his dragons to go rampage, unleashing their anger. Feeling that his dragons were also not yet satisfied with their battles and seeking to attain the strongest power, Zarc fused himself with his four dragons to become a single dragon that people called the Supreme King Dragon Zarc. After Zarc's declaration of destruction, the armed military was unable to stop his continuous attacks on the world due to his body made from Solid Vision, and eventually he was only able to be opposed by other Duelists who collaborated with the military to stop him, but none were able to come close to matching his newly fused powers and were wiped away along with the opposing military forces.undefined When the Supreme King Dragon Zarc was confronted by Ray, he was defeated by her four cards and started to split back into four dragons. Before being separated, they vowed to become one again and was sent each of the Four Dimensions with an incarnation of Zarc's soul.undefined

Revival
When Yūya arrived at Academia and confronted Leo Akaba, the Professor revealed the history between him, Ray, and Zarc, including that Yūya and his counterparts were the reincarnations of Zarc himself. During their Duel, Yūya and Yūto's anger allowed Zarc to start gaining control over them. At the same time, Yūgo and Yūri, who were duelling each other, summoned their respective dragons, causing a resonance that strengthened Zarc's influence over them. Yūri, who became aware of their origin, defeated Yūgo and absorbed him, deciding to fulfil Zarc's wish.undefinedundefinedundefined Yūri made his way to the chambers where Yūya was, carding his father right in front of him, causing Yūya to accept Yūri's challenge to Duel.undefined As the Duel went on, Zarc's influence became too much for Yūya and Yūto to bear, and Yūto eventually succumbed to his influence when Yūri took control of "Dark Rebellion Xyz Dragon".undefined Yūya was able to resist Zarc's control and defeated Yūri by taking control of "Odd-Eyes Pendulum Dragon", "Clear Wing Synchro Dragon", and "Dark Rebellion". However, during the Duel, Yūya focused only to win the Duel, something that became Zarc's driving force ever since he started to fell into madness, which allowed Zarc to fully take control of Yūya. He absorbed his remaining reincarnations and fused himself with his four dragons using "Astrograph Magician", reviving him a whole.undefined

Duel Against Sora & Edo
The Supreme King Dragon started his attack on Fusion Dimension, declaring his desire to destroy everything as he revealed to the residents of the dimension that he was born from their desire. As he was attacking the town, he demanded for someone to Duel him, which granted when Edo and Sora confronted him. Zarc separated himself from the Supreme King Dragon to duel the both of them. When Edo and Sora destroyed all of Zarc's monsters, Zarc summoned "Astrograph Magician" to perform Integration Summon, fusing himself again with the four dragons, summoning back Supreme King Dragon Zarc and easily defeated both Edo and Sora before facing against Shun and Kaito who came to help them.undefined

Duel Against Shun & Kaito
During Shun's turn, the Supreme King Dragon activated his effect that allowed Zarc to perform Xyz Summon right after Shun performed the same summoning. Zarc summoned "Supreme King Servant Dragon Dark Rebellion". When Shun declared attack on the Supreme King Dragon, Zarc activated "Dark Rebellion's" effect so that both Shun and Kaito cannot attack other Xyz Monster other than "Dark Rebellion". Since the Supreme King Dragon is the integration monster of all summoning methods, he was also treated as an Xyz Monster. In addition to this, Zarc activated another of his effect that made "Dark Rebellion" unaffected by any Fusion, Synchro, or Xyz effects, so the Supreme King Dragon cannot be attacked unless "Dark Rebellion" is destroyed.

When Shun and Kaito able to power up their monsters and activated Trap Card that will banish "Dark Rebellion" at the end of turn, Zarc released "Dark Rebellion" back to Extra Deck and summoned back its Xyz Materials to turn their monsters' ATK to 0. In respond to this, Shun and Kaito picked Action Cards to avoid the battle damage, but the Supreme King Dragon activated its next effect that negated and destroyed any card that they added to their hands outside Draw Phase. Noticing Jack and Gongenzaka intruded the Duel, Zarc declared attack on Shun and Kaito, defeating them, and then turned his attention to Jack and Gongnenzaka.
