He is the original incarnation of Yuya Sakaki (Standard Dimension), Yuto (Xyz Dimension), Yugo (Synchro Dimension), and Yuri (Fusion Dimension).

During a confrontation with Ray Akaba, Zarc's soul was split into four and reincarnated into four different lives. He is the original owner of the Four Dimension Dragons.

Appearance
Zarc shares mixed traits to his four dimensional soul fragments. Zarc has silver hair with light green highlights, having striking similarities in hair design to the dual-hair color of all of his dimensional soul fragments and Yuri's side-parted hair. He wears a blue and white jacket with orange borders, like Yugo's Duel Suit, and a black undershirt. He is shown to wear thick red-brownish gloves, black pants with a brown chaps, faded gold knee pads, dark-blue suspenders with faded gold buckles hanging from a red-brownish belt with two large holsters, like Yuto's belt, a large faded gold buckle, and brown shoes with dark-blue outlines and straps.

Zarc's revived body takes the form of Yuya - the final survivor of the battle between his reincarnations, a mixture between dragon, human, and demon. His body turns gray and become bulkier with spikes protruding from his shoulders, arms, and ankles while his eyes turn bright yellow. His face is covered in veins and his ears are replaced by wing-like appendages. In this form, he no longer wears a shirt or shoes and has a large pair of black demonic wings on his back.

Personality
While Zarc's initial personality is unknown, it is shown that he shares parts of his personality to that of his multiple reincarnations. He has a passion for entertaining duels similar to Yuya's love for Action Duels, albeit different in that he shows little to no care for his opponents' well-being, willing to physically injure them ruthlessly like a gladiator, rather than make an amicable connection to both them and the audience. Like Yuri, he's shown to be extremely ruthless and violent towards his opponents, sparing no one and shown taking pleasure in harming his opponents and Dueling spectators in order to satisfy his hunger for power. Like Yuto, he displays extreme aggression and great anger. Like Yugo, he also desires to stand at the top of the dueling world.

Zarc's most defining trait is his lust for power, having been fueled by the crowd's desire for more brutal Duels in the ARC System. His desire to become stronger was so great, he had been driven to insanity, while also fueled by the anger of his four dragons.

Abilities
Zarc has the unique ability to hear the voices of Duel Monsters and entered an Awakened state when he fused with his dragons. Following his split, he has the ability to possess his reincarnations by forcing them into an Awakened state to compel them to merge with each other and facilitate his rebirth.

History
Zarc was a resident of the Original Dimension. He was a Duelist who claimed to be able to hear the voices of duel monsters and connect his heart with them. Due to this, he was very skilled in Dueling and quickly gained the advantage on the field, soon becoming an undefeated Duel champion and widely known as a superstar in then newly conceived ARC System. He started to change after he accidentally severely injured one of his opponents yet the audience kept cheering for him, leading Zarc to believe such aggressive Dueling was fine if the audience desired it. Since then, Zarc's Dueling became more violent.

After Zarc's declaration of destruction, the armed military was unable to stop his continuous attacks on the world, 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.

As Zarc destroyed the city, he was confronted by Ray Akaba, who used four cards to defeat him, which angered him and vowed to become one before his dragons separated from him. However, the result of their battle led to the United World to be split into Four Dimensions while his soul split into four, reviving in each of the dimensions as Yuya Sakaki (Standard), Yuto (Xyz), Yugo (Synchro), and Yuri (Fusion).
