As the union of the four dimensions begin, Yuya continues to struggle against Yuri who continuously gains an advantage in Action Cards. The continuous interference forces Yuya to send Smile World into the graveyard to avoid the finishing blow, which greatly horrifies him since the card symbolizes his bond with his father. It was not until Declan, Riley, Sora, and Aster expresses their faith in him that Yuya regains his determination. Focusing only to win the duel, Yuya was able to take back Yuto's Dark Rebellion Xyz Dragon and take control of Yugo's Clear Wing Synchro Dragon. Yuya defeats Yuri's Starving Venom Fusion Dragon with Odd-Eyes Pendulum Dragon. After the duel, Zarc reveals that he has fully taken control of Yuya's body and soul. Zarc summons Astrograph Sorcerer and fuses with his reincarnations, which revives himself as the Supreme King Z-ARC.
