Zarkovia was featured in Viktor: The Spoils. An absolute monarchy-based country, it had been besieged by anti-government rebels in a civil war. Prince Gyula wished to crush the rebels, using the mindless body of Viktor. However, his father, King Xarion, convinced Ben and his team to come to the country. Using Ben's powers, he placed his own mind in Viktor's body. Ben defeated King Viktor and freed Gyula's mind-controlled soldiers, deciding not to interfere in "local politics."
What became of Zarkovia afterwards is currently unknown.
