At some point, Yuri became a military colonel in Markovia.
Yuri later took a large force of Markovians to invade Freeland in order to kidnap Helga Jace, Lynn Stewart and various meta-humans. This led to the A.S.A. opposing them by creating their own batch of meta-humans. However, after the A.S.A. began finding themselves opposed by both Freeland and Black Lightning, Yuri then hired Instant to attack the Freeland Police Department in order to abduct Helga Jace, who was held there for safekeeping.
During the Anti-Monitor Crisis, Yuri as well as everyone in the multiverse except for the seven Paragons, was killed in an antimatter wave by the Anti-Monitor on December 10, 2019, only to be restored a month later, after the Paragons and the Spectre created a new universe.
Once Helga Jace was sent back to Markovia, Yuri ordered her to work on a serum capable of creating meta-humans and set his sights on Lynn Stewart. Once she was also taken and sent to Markovia, Yuri had both doctors work on the serum.
After Lynn injected herself with the serum, she controlled Yuri's mind and forced him to help them escape. Then he was knocked out and passed out.
