Changes

Zarc Summoned "[[Supreme King Dragon Odd-Eyes (anime)|Supreme King Dragon Odd-Eyes]]" during Sylvio's turn with its own effect when Sylvio Pendulum Summoned. Sylvio attempted to add "[[Abyss Script - Rise of the Abyss King (anime)|Abyss Script - Rise of the Abyss King]]" to his hand with the effect of "[[Abyss Actor - Superstar (anime)|Abyss Actor - Superstar]]", but the effect "Z-ARC" destroyed it. To Zarc's anger, Sylvio commented that Zarc was scared, and Set "Rise of the Abyss King" directly to the field with "[[Abyss Script - Abyss Entertainment (anime)|Abyss Script - Abyss Entertainment]]", bypassing the effect of "Z-ARC". Sylvio attempted to use "Rise of the Abyss King" to destroy "Z-ARC" and "Odd-Eyes", but the effect of "Odd-Eyes" to protected Zarc's Pendulum Monsters from being destroyed. Sylvio claimed that the Yuya Sakaki he knew wasn't a coward and braved danger to pull off a great escape. Sylvio re-Set "Rise of the Abyss King" with "Abyss Entertainment", attempting to destroy "Z-ARC", but Zarc revealed that he could not be destroyed as long as there were [[Fusion Monster|Fusion]], [[Synchro Monster|Synchro]], and [[Xyz Monster]]s banished or in the Graveyards. [[Leo Akaba]] entered the Duel, and Zarc remembered him as the man who revolutionized Dueling with the [[ARC System]]. Zarc declared that his vow to be a strong and terrifying existence to fight all enemies until the world was destroyed had not changed. He sent "Supreme King Dance" to the Graveyard to force "Chidori" and "Superstar" to attack "Z-ARC", destroying them both while using the effect of "Odd-Eyes" to double the damage, defeating Sylvio and Crow. Zarc declared that he would defeat Leo as well, until Leo mentioned the [[Natural Energy Cards|four cards]] that had defeated him in the past, angering Zarc. Before Leo could use the cards, Zarc activated "[[Supreme King Brutality]]" to send the cards to the Graveyard and inflict damage for each sent card, defeating Leo.<ref name="ep139" />

The defeats of Sylvio, Crow and Leo left Declan as Zarc's sole opponent. To Zarc's surprise, Declan reminded Yuya that he was the founder of Pendulum Summoning. Zarc observed Declan Pendulum-Xyz, Synchro, and Fusion Summon "[[D/D/D Wave High King Executive Caesar (anime)|D/D/D Wave High King Executive Caesar]]", "[[D/D/D Gust High King Executive Alexander (anime)|D/D/D Gust High King Executive Alexander]]", and "[[D/D/D Flame High King Executive Genghis (anime)|D/D/D Flame High King Executive Genghis]]", admitting that Declan was different from his other opponents. Declan negated the effects of "Zero" and "Infinity", and destroyed "Odd-Eyes" when Zarc tried to use its effect to revive his "Darkwurms", before attacking "Z-ARC" with all three "High King Executives", suffering severe damage despite his inability to be destroyed. Zarc laughed at Declan's misunderstanding before claiming that he was the true founder of Pendulum Summoning, which was born for his revenge against [[Ray Akaba|Ray]] when the Original Dimension was divided. Due to the damage he had suffered, Zarc was able to bring out all four of his [[Supreme King Dragon]]s with "[[Supreme King's Wrath]]", including "[[Supreme King Dragon Starving Venom (anime)|Supreme King Dragon Starving Venom]]". Zarc attacked the "High King Executives" with the "Supreme King Dragons" and their effects, as Declan countered with the Pendulum and monster effects of "[[D/D Savant Dirac]]" and "[[D/D Savant Schrödinger]]", eventually breaking through Declan's defenses and defeating him with the final attack from "Z-ARC" as Riley entered the Duel.<ref name="ep140" />
