→History
Zarc was a resident of the [[Original Dimension]]. He was a Duelist who claimed to be able to hear the voices of 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 [[Solid Vision|Real Solid Vision]] Dueling. 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. At first, he simply wanted to answer his fans' expectations, however as he continued to Duel more and more, Zarc himself became obsessed with becoming the strongest.
Eventually in a tournament, he Summoned his four dragons, "{{Anime|Odd-Eyes Dragon}}", "{{Anime|Dark Rebellion Xyz Dragon}}", "{{Anime|Clear Wing Synchro Dragon}}", and "{{Anime|Starve Venom Fusion Dragon}}" to destroy everything in his way. 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, becoming a single dragon that people called the [[Supreme Dragon King Zarc(character)|Supreme Dragon King Zarc]].
Zarc was on the verge of destroying the whole world when [[Leo Akaba]]'s daughter [[Ray (ARC-V)|Ray]] opposed him, resulting in the original world being split into four dimensions. Since then, Zarc's split soul has resided within [[Yuya]] [[Yuto|and]] [[Yugo|his]] [[Yuri|counterparts]] and constantly tries to consume them for the sake of his revival.
