[[File:Zarc_Loss.png|thumb|Zarc is finally defeated by Ray and Riley.]]

Riley revealed that she was being possessed by Ray, and to Zarc's shock and anger she used the Natural Energy Cards to destroy "Z-ARC" and the "Supreme King Dragons". Riley called out to Yuya, and Zarc insisted that he wasn't Yuya. Declan explained that Zarc was both himself ''and'', since his heart was constantly swinging like a pendulum. Ray also claimed that Pendulum Summoning wasn't just born from Zarc's malice and she declared that Yuya still existed within him. Zarc continued to deny their claims, until [[Zuzu Boyle|Zuzu]] called to him from within Riley. She urged Yuya to remember how he wanted make people around the world smile. Zarc denied those smiles, claiming that he wanted to spread fear, but Yuya managed to regain control of their body after remembering his mission to save Zuzu. Zarc began to fight Yuya for control when he used "[[Smile Universe (anime)|Smile Universe]]" to revive "Z-ARC" and "Odd-Eyes", proclaiming Pendulum Monsters as immortals. Furious that his alter ego was getting in his way, Zarc ordered Yuya to stop, but he was finally defeated when they used "[[En Flowers]]" to destroy his dragons and inflict damage for each one. The power of the Natural Energy Cards began to split Zarc and the Four Dimensions again, but Riley ejected Ray's soul from her body, removed Zarc's soul from Yuya's body, and sealed it within her own body to prevent his revival again.<ref name="ep140" />
