|“What I am? I'm his trusted advisor, while you are nothing but a traitor and a rebel spy. And sooner or later, I will deal with you, as I deal with all who stand in my way.”|
|— Vex to Lloyd|
Vex (also known as Vex the Pathetic, Vex the Shameful, and Vex the Formless) was a Formling who did not find his animal form, and due to this, he left the village and aided Zane in capturing the Never-Realm.
Vex seems to be manipulative, cruel, and intelligent. He seems to be loyal toward his master, the Ice Emperor, since he wants his enemies to know his strength. Vex appears to love attacking people, as he persuaded his emperor to allow him to destroy the Ninja and the civilians helping them rather than punishing them. However, Vex can be merciful as he offered his prisoner a deal of sparing Lloyd if the prisoner joined him.

After not finding his animal form and people mocking him, Vex left the the village of the Formlings, and after years of traveling in the wilderness. Then he found the Ice Emperor and he became second-in-command. The ice served him, and he controlled Dark Ice. When Zane attempted to reboot the Titan Mech, which had landed in the realm with him, Vex pulled the diagnostics cable and Zane lost his memories. Vex manipulated Zane into thinking that he was his loyal advisor and told him to conquer the Never-Realm. With the help of his "new partner," he got revenge by freezing the Formlings and plunged his realm into subjugation. 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. When Vex attempted to kill Lloyd, he said the word "protect," causing Zane to regain his memories, destroy his scepter, and freeze Vex. Not long after, Vex was recognized as the true tyrant of the realm and was banished further into the outskirts of the Never-Realm.
