Gyula is a handsome young man. He wears a royal military uniform, with a military badge on the left breast.
Gyula believes that he's the future of Zarkovia, and that his father is weak and old. He also blames his father for his mother's death. He is willing to do anything to become the new king of Zarkovia.
Gyula was disgusted at his father's refusal to stamp out a rebel uprising. Locating the braindead body of Dr. Viktor, he intended to use it to destroy the rebels. Ben, Gwen and Kevin attempted to stop him, but the mindless Viktor (under the control of Gyula) defeated them, and they were imprisoned, along with King Xarion. However, Xarion escaped and used AmpFibian's powers to place his mind in Viktor's body, attacking Gyula soon after. After Ben defeated "King" Viktor, Gyula attempted to finish off the rebels, only for Ben to release his mind-controlled soldiers from his control. This severely depleted the prince's forces, as the freed soldiers immediately left the area.
