Sergei Ivanovich Petrofsky

 Sergei Ivanovich Petrofsky  is a supporting antagonist of the 1996 film, Eraser. He is a leader of a Russian mafia bent on buying electromagnetic pulse rifles that will usher a new era of global terrorism.

Role
According to U.S. Marshal John Kruger, Petrofsky is known to have sold drugs and weaponry in his country. Recently, Undersecretary of Defense Daniel Harper has arranged an arms sale of railguns (created by Cyrez CEO William Donahue) and assigned his right-hand man Robert Deguerin to oversee the shipment onto Petrofsky's freighter ship at the Baltimor docks.

After Cyrez executive Lee Cullen is kidnapped by Deguerin, she is brought over to the docks, where she is introduced to Petrofsky while being tied up to a chair. As Deguerin takes up the responsibility of putting up the last cargo box onto Petrofsky's ship, Kruger arrives to stall the shipment by using two railguns to take down many of Deguerin's men. The commotion distracted Petrofsky long enough for Cullen to free herself and knock him down before escaping.

After recuperating, Petrofsky and his men spot Kruger trying to catch Degeurin, so they try to gun him down. Fortunately, Kruger brought in Johnny Castleone (a mob witness whom Krguer saved earlier), who brought in Tony Two-Toes (who owns the docks and is disgusted by the illegal arms sale) to help. Taking refuge inside a bulldozer, Johnny, Tony, and their men manage to gun down Petrofsky and his men to their deaths while Kruger defeats Deguering and hands him over to the authorities.
