Driven mad by his insecurity, he delusionally believed everyone insulted him behind his back and exiled himself of his own will. However, he was unable to find his animal form. Vex was born in the Village of the Formlings, a race of beings with the ability to turn into various animals. 4.2.1 Season 11: Secrets of the Forbidden Spinjitzu.
When Vex attempted to kill Lloyd, he said the word "protect," causing Zane to regain his memories, destroy his scepter, and freeze Vex. Vex stood by the side of his "master," the Ice Emperor, as the Never-Realm fell underneath his control through his scheming manipulation of Zane. With the help of his "new partner," he got revenge by freezing the Formlings and plunged his realm into subjugation. Vex manipulated Zane into thinking that he was his loyal adviser and told him to conquer the Never-Realm. When Zane attempted to reboot the Titan Mech, which had landed in the realm with him, Vex pulled the plug and Zane lost his memories. Due to this, he left the village, and after years of traveling in the wilderness, he eventually found Zane, who had been banished to the Never-Realm following a battle with Aspheera. He was a Formling who did not find his animal form, and thought himself to be mocked and looked down upon by his people. See the Architecture Guide for a look behind the scenes of Vex.Vex (also known as Vex the Formless) is the former general of the Blizzard Samurai.
