His ultimate goal is world domination and plans to acchieve this with his psychically/DNA-enhanced army. He appeared in the videogame Command & Conquer: Red Alert 2 and its sequel Yuri's Revenge, where he became a threat to the world with both playable factions the Allies(USA and allies) and the Soviets (USSR and allies) to foil his plot.
His appearance bears an uncanny resemblance to Vladimir Lenin, with a bald head and goatee. On his forehead are tattooed three Hebrew letters "resh", "vav", and "yod", while psi stimulators linked to a psi collar underneath his clothes is surgically implanted into his skull.
He is of Romanian ancestry and inherited the Translyvania Castle from his family. He helped in Stalin in his secret project involves the creation of a psychically enhanced army to gain a tactical advantage for the Soviet Union in their fight against the United States. The USSR still lost and Stalin was killed. Yuri help Premier Romanov in reaarming the USSR by providing psychic technology which led to the formation of the Psychic Corps, a branch of the Soviet military specializing in said technology.
Third World War
Yuri played a major role in planning and executing the Soviet Invasion of America. Yuri helped the Soviets in constructing giant Psychic Beacons which aims to brainwash the Americans, preventing a risk of nuclear missle-exchange.
The Allies only knew Yuri's role as chief advisor of Premier Romanov, Although they have suspicion that he may have a much larger role. After the fall of Moscow, he is nowhere to be found.
Yuri was sympathetic to the Soviet Commander (the player) after General Vladimir took credit for the commander's victory in Florida. Yuri, impressed by the commander's skills, started sending him to important missions. He later assasinated Premier Romanov and assumed the post of Premier himself. Yuri took away General Vladimir's authority on the Red Navy to the commander. After Pearl Harbour fell to the Soviets due to the commander's efforts, Yuri framed General Vladimir for the murder of Premier Romanov. The clueless commander later captured Vladimir.
Upon the destruction of the Weather Control Device in the US Virgin Islands in the hands of the commander, Yuri realised that the commander was proving "even more tenacious than he thought" and invited the commander to Moscow to "congratulate" him personally. However the commander figured out the truth the Yuri was the one whi killed Romanov and seized the Kremlin with his army. Despite of Yuri's continued taunts and the threat posed by his Psychic Corps he was crushed by the collapsing building.
The Soviets were hailed the victor, destroying the last Allied stronghold in Alaska that housed the Chronosphere and the commander was hailed as the new Premier. Shortly after his victory, he inexplicably heard the voice of Yuri in his mind.
Psychic Dominator Disaster
During the Psychic Dominator Disaster, Yuri had stolen Soviet cloning technology; using it to create a number of clones. However, to protect himself from any clone plotting against him, Yuri engineered his clones to be inferior to his own. Yuri himself was seen on the battlefield once or twice; he stood upon a hovering platform which rendered him immune to being trampled, and allowed him to cross over water. His powers were so well developed that he could mind control entire enemy structures, through the personnel within.
After the Allies had finally defeated Romanov's forces through a surprise Chronospher invasion of Moscow, Yuri resurfaced. However, he had abandoned his former employers, and revealed that during the war, he had raised an army of his own and a planned to take over the world with mind-controlling Psychic Dominator in specific points all over the world. Yuri personally contacted President Dugan to gloat over this plan.
Dugan originally tried to dissuade Yuri with an amnesty offer and leadership of Russia, however, Yuri preferred the to rule the entire world over one country. At that point President Dugan ordered an air strike which failed to destroy the Dominator in San Francisco, but damaged the nearby nuclear power plant providing power to the machine, allowing some Allied and Soviet command centers to avoid falling under Yuri's control. However, an overwhelming majority of humanity succumbed to Yuri's dominance permanently.
Albert Einstein invented a new time machine which allowed the Allies to travel back to a point in time when the Dominators were incomplete. They destroyed most of Yuri's bases and, after convincing the Soviets that Yuri was an enemy of everyone on the planet, the Allies and Soviets took up arms against Yuri together.
After his final defeat in Antarctica, in the Allied account Yuri was captured and put into a Psychic Isolation Chamber, which was used to strip him of his mind control abilities. As General Carville put it best: "He won't be able to mind control a fly.". He would have stayed in his chamber for the rest of his life, had there not been the merging of the timelines caused by the time-travel.
Soviets used Einstein's time machine to revert the disaster and to punish Yuri by Soviet hands. After destroying the Chronosphere to prevent the war-ending chrono-attack, Moscow then fought against Yuri and his uncompleted Dominators. It appeared that Yuri had a base on the Moon where he'd stay after the successful Psychic Dominator Disaster. However the base was destroyed, thus Yuri had to retreat to his ancestral family castle in Transylvania.
The castle was guarded by Yuri's forces as well as bases of Allies and Soviets loyal to him due to the fact that they were under control of his old, operational Psychic beacons. Fortunately, the beacons were destroyed and the castle, surrounded from all sides, was an easy target for the Red Army. However, Yuri still had one surprise. Under the ruins of the structure he had a time machine, the same one which the Soviets used to revert the Psychic Domination Disaster. Yuri wanted to time-travel back in past to revert the reverting of Psychic Dominator Disaster. He was just commencing time-travel with tense: "The world will be mine to Command and Conquer."
However, Zofia used the machine command-codes to overload the machine's power by overloading its circuits. This caused Yuri to travel way too far into the past - to the age of dinosaurs. From there, Yuri is attacked, and presumably slain, by a Tyrannosaurus Rex.
