Vasily Hunyadi was a Romanian Augment who fought in the civil wars consuming the former Yugoslavia on Earth in the early 1990s, which he himself had instigated. His main headquarters was located in Dubrovnik, Croatia but he also had many strongholds in Serbia and Bosnia-Herzegovina. Prior to June 1993, he had lost his left eye in battle and had been accused by United Nations observers of practicing "ethnic cleansing." At that time, he wore a drooping moustache and had noticeably bushy eyebrows.

He and Khan Noonien Singh attempted to assassinate each other on several occasions. Khan survived an artificially created earthquake in Maharashta region of Central India on September 30, 1993. Hunyadi repelled a submarine attack which cost Khan his ballistic missile submarine, the SGK Kaur, in a battle which took place beneath the Mediterranean Sea on February 7, 1994.

On August 29, 1994, Hunyadi addressed the United Nations in defiance against the economic sanctions and the NATO peacekeeping presence. The Palais des Nations in Paris was poisoned with the nerve toxin sarin gas, claiming the lives of many ambassadors and tourists, including Hunyadi. The sarin gas had been provided by the American Augment General Randall "Hawkeye" Morrison, the founder of the Southern Arizona-based militia group Army of Eternal Vigilance. Khan had entered into a temporary alliance with Morrison in order to rid himself of Hunyadi as he sought revenge for the deaths of the more than 10,000 Indian nationals killed in the Maharashtra earthquake the previous year, as well as for the near-fatal injuries suffered by his personal bodyguard Joaquin Weiss.

Clare Raymond, one of the tourists killed in the United Nations that day, had never heard of Hunyadi prior to her revival from cryonic stasis in 2364. (DTI novel: Watching the Clock)
