Sergei "Serge" Malatov, ( Ukrainian: Сергій Малатов ) also known as Boris, acts as a driver and muscle for The Greek. He is Ukrainian, although Americans often assume he is Russian. He hates this and their subsequent tendency to nickname him "Boris" (based on Boris Badenov). He is responsible for picking up containers of stolen goods from the port and taking them to The Greek's front warehouse to be fenced. According to him, he is from Kiev and he was incarcerated four years in Ukraine. Sergei is played by Chris Ashworth.
