King Xarion (father) Unnamed mother (deceased)
Viktor: The Spoils
Prince Gyula is the prince of Zarkovia. He first appears in .
Viktor: The Spoils
Gyula looks like a fine and handsome man wearing his royal military uniform and has a military badge on his left chest.
Gyula thinks that he's the future of Zarkovia, thinking that his father is weak and old, including blaming him for his mother's death. He'll do anything to become the new king of Zarkovia.
The son of
King Xarion, Gyula was disgusted at his father's refusal to stamp out a rebel uprising. Locating the braindead body of Dr.Vicktor, he intended to use it to destroy the rebels. Ben, Gwen and Kevin attempted to stop him, but the mindless Vicktor (under the control of Gyula) defeated them, and they were imprisoned, along with King Xarion. However, he escaped and used AmpFibian's powers to place his mind in Vicktor's body, attacking Gyula soon after. After Ben defeated "King" Vicktor, Gyula attempted to finish off the rebels, only for Ben to release his mind-controlled soldiers from his control, severely depleting the prince's forces as the freed ones immediately left the area.
