Changes

On the morning of the third day of the [[World Duel Carnival]], Trey set out to find [[Yuma Tsukumo]]. While doing so, he stumbled upon him Dueling [[Reginald Kastle|Shark]]. During the Duel, Trey was shocked at how Yuma was letting Shark take his anger out on him by [[destroy]]ing his monsters, without fighting back. He then snuck into Yuma's house and was amazed at the artifacts that [[Kazuma Tsukumo|his father]] had collected. While looking with amazement at the artifacts, [[Haru Tsukumo]] heard him and asked him what he was doing and informed Yuma that he was there. When Yuma returned, Trey was wearing a mask similar to "[[Chronomaly Aztec Mask Golem|a card]]" his father had given him as a child. Trey told Yuma that he was no threat and Haru invited him to have lunch with them. During lunch, seeing Yuma and [[Kari Tsukumo|his sister]] arguing, reminded him of his family and how happy they were in the past. Feeling more and more depressed about how his family has changed since then, Trey cries and leaves in the middle of dinner. Trey then decides, for his family, to challenge Yuma to a Duel in order to acquire Yuma's power of never giving up until the very end. Vetrix agreed to this and told Trey he would give him new powers to help him beat Yuma.<ref name="e46"/>

[[Vetrix]] performed a ritual on Trey, similar to the one he had with [[Hart Tenjo|Hart]], transferring some of his power into Trey's crest, which Vetrix called the powers equivalent to the pain that Trey had felt in his life. In addition, he gave him two new cards - "[[Number 6: Chronomaly Atlandis]]" and "[[Final Prophecy]]". Vetrix told him that the former card would put him a great strain on him both physically and mentally and that the latter card would ensure that both players do not walk away unharmed.<ref name="ep49"/> That evening, Trey awaited [[Yuma Tsukumo|Yuma]]'s arrival atop a series of unfinished roads. Yuma told him he believed they could become friends after the Duel, and Trey told him he must defeat Yuma to save his family. The two then began to Duel, with Trey telling Yuma that with his new powers, he can't be defeated, and was also able to clearly perceive [[Astral]]. On his first turn, Trey managed to Summon "Machu Mech", gaining a massive upperhand over Yuma, who could defend with his weaker [[Monster Card]]s. Trey went so far as to call his weaker monsters his pawns, shocking Yuma when he sacrificed his [[Chronomaly Aztec Mask Golem|favorite card]] to aide his strategy. After Yuma managed to make a comeback with his "[[Gagagarush]]", Trey becomes angry, using his crest to send Yuma into an abyss, where he forgot his worldview - "[[Kattobingu]]". Trey then made Yuma live out his life's main events without his "Kattobingu", which resulted in him becoming a shy and scared individual. When Yuma returned to the present, he can no longer perceive Astral or the [[Emperor's Key]] and is too scared to do anything. Trey then used his powers to chain Astral to a tower and attacks Yuma with his "Machu Mech", causing him to fall on the floor in pain, while Trey sadistically laughed.<ref name="e47"/>
