He attacked Yuya with "Dark Rebellion" and used "[[Crush Action]]" to destroy Yuya's action cards but he used "[[Farewell]]" to end the battle. When Declan, Riley, Sora, and Aster revived Yuya's broken spirit, Yuri started to clap and was happy that he got motivated because he would've frustrated if he was left in his broken state. When Yuya received from pain bringing back "Odd-Eyes", Yuri told him he'll never learn. He then lost control of "Dark Rebellion" and "Clear Wing" when Yuya used the effect of "[[Performapal Trap Mimic]]" to destroy "Dragon Creeping Plant" and copy its effect. However, he used "[[Predaplant Reborn]]" to Special Summon "Stapelia Worm" from the graveyard. When Yuya used the effect of "Dark Rebellion" on "Starving Venom", Yuri used the effect "Stapelia Worm" to negate the effect "Dark Rebellion" and destroy it. But, Yuya used the effect of "Clear Wing" to negate the effect of "Stapelia Worm" and destroy it and used the effect of "Dark Rebellion" again. Yuri then used "[[Ridicule World]]" to increase all of Yuya's monsters ATK, but prevents them from attacking. However, Yuya used the second effect of "Flat Rat" to change Odd-Eyes ATK back to normal by Tributing it. He was then defeated by Yuya and was glad his first loss was to him because they were counterparts. He pulled out Yusho's card keeping his promise and told Yuya to absorb him quickly. He then awakened and was absorbed by Yuya, who finally succumbed to Zarc's will to [[Astrograph Sorcerer (anime)|fuse]] back into the [[Supreme King Z-ARC (character)|Supreme King Z-ARC]].<ref name="ep135" />
[[File:Zarc attacks students.png|thumb|left|The students are attacked by Supreme King Z-ARC.]]
When a dimensional rift opened with the Supreme King Z-ARC, the soldiers in Heartland stared in shock. At Duel Academy, the students were questioned by Supreme King Z-ARC for their fear, even though he resurrected for them. Some of the students told the Supreme King they didn't want this, but were silenced and attacked by him. Meanwhile, as his throne gets close to ARC-V, Leo checks to see why Ray wasn't reviving and wondered if the life energy was insufficient. He then screamed Ray's name in anger<ref name="ep136">{{episode|Yu-Gi-Oh! ARC-V|136|ref}}</ref>, grabbed the four cards and joined the Duel against Zarc, receiving an intrusion penalty. Leo asked Zarc if he do still remember him as he watched [[Sylvio Sawatari|Sylvio]] and [[Crow Hogan (ARC-V)|Crow]] get defeated. He vowed to defeat Zarc on Ray's behalf and make the Four Dimensions one again. He used "[[Spirit Collapse]]" to send "Pendulum Ruler" to the [[Graveyard]] stating that since there are three Fusion monsters in the graveyard, the conditions have been met. He was surprised when Declan joined the Duel, who told Leo he wasn't the only person who caused Zarc to become evil. Leo prepared to use the four cards, but Zarc activated "[[Supreme King Brutality]]" to send the cards to the Graveyard and inflict damage for each sent card, defeating Leo. He was then sent flying into the building and caught by Declan.<ref name="ep139">{{episode|Yu-Gi-Oh! ARC-V|139|ref}}</ref>
Leo punched the ground in anger as his plan to seal Zarc was gone, but Declan told him they still have hope as everyone that Dueled Zarc believe Yuya's soul is inside of him. When Zarc revealed that he was the true founder of Pendulum and vowed to win their next battle, Leo was surprised he was talking about Ray. Leo then mentioned how Ray splendidly used the [[Natural Energy Cards]] to split Supreme King Z-ARC but at a cost. When Zarc began attacking with his [[Supreme King Dragon]]", was confident Declan wouldn't take damage due to the Pendulum effects of his monsters. However, he was worried when Declan was almost defeated and both of them were saved by [[Moon Shadow]] from "[[Supreme King Z-ARC (anime)|Supreme King Z-ARC]]'s" attack. He was surprised when Ray returned by possessing Riley's body and was happy when used the Natural Energy Cards to destroy "ZarcZ-ARC" and his "Supreme King Dragons". When Riley and Ray defeated Zarc, Leo noted that the world was about to split into four again.<ref name="ep140">{{episode|Yu-Gi-Oh! ARC-V|140|ref}}</ref> Following the battle, all of the carded students were freed from their cards.<ref name="ep141">{{episode|Yu-Gi-Oh! ARC-V|141|ref}}</ref>
Following the battle against Zarc, [[Dennis McField|Dennis]] was freed from his card and appeared before Yuya, who was traveling through the [[Interdimensional Travel Technology|dimensional corridor gate]], in the [[Xyz Dimension]].<ref name="ep143">{{episode|Yu-Gi-Oh! ARC-V|143|ref}}</ref> He told Yuya that he would be his opponent instead of Shay, due to him going to the [[Fusion Dimension]] to save Lulu. When Yuya was about go there, Dennis stopped him since he still wanted to Duel and revealed that he was one of Yusho's students. He told Yuya he could go if he won and pointed out the spectators, making him accept the challenge. But when their parents didn't want them to watch the Duel, Dennis revealed his "[[Polymerization (anime)|Polymerization]]" and threatened to [[Human Sealing Technology|seal them back into cards]] if they didn't watch. He Fusion Summoned "[[Performage Trapeze Force Witch]]" and [[equip]]ed "[[Ancient Gear Mask]]" it. He attacked "Odd-Eyes", using the combined effects of "Force Witch" and "Ancient Gear Mask" to weaken "Odd-Eyes" prevent Yuya from using [[Spell Card|Spell]] or [[Trap Card]]s. This destroyed "Odd-Eyes". As Yuya wondered why Dennis was acting evil Aster appeared during their Duel with [[Mamoru Noro|Mamoru]], [[Gloria Tyler|Gloria]], and [[Grace Tyler|Grace]] to tell Yuya that it was Duel Academy's fault that they're being seen as detestable beings for sealing everybody into cards and even if they restore the Xyz Dimension, the people still won't forgive them due to inflicting large wounds. He told Yuya that if he could communicate with Dueling, they might be able to see a solution.<ref name="ep144">{{episode|Yu-Gi-Oh! ARC-V|144|ref}}</ref>
