Though his appearance is that of a child younger than the rest of the [[Vetrix Family]], he is their father. He was betrayed by Dr. Faker, who used him and [[Kazuma Tsukumo]] as sacrifices to open the door to another dimension.

During the Duel between [[Yuma Tsukumo|Yuma]] and [[Nash]], the Astral and Barian Worlds were close to colliding and destroying both. Vetrix appeared in the Barian World (now fully fused with [[Earth (planet)|Earth]]), while [[Kazuma Tsukumo|Kazuma]] appeared in the Astral World. Kazuma thanked Vetrix, saying that his sons had helped Yuma grow into a fine young man. Vetrix thanked him in turn, as Yuma helped him get his family back. Vetrix determined they had to find a way to stabilize the worlds long enough for the Duel to come to its conclusion. Kazuma agreed, and the two entered energy forms of the same colors used by Yuma and Astral before using [[ZEXAL (power)|ZEXAL]]. They used the last of their powers to become barriers between the arena and the two colliding worlds. Vetrix's crest shined out (now pink once again), while an image of the [[Emperor's Key]] shined out for Kazuma.<ref name="ep142">{{episode|Yu-Gi-Oh!
