"Bugsy" Bugoff was a killer-for-hire. He was a heavyset man with light hair and dark eyebrows.
He had a habit of telling people not to do certain things, saying "Dat bugs me."
Bugsy was the mastermind of a sophisticated industrial espionage scheme. He ran a seemingly-legitimate pest control company. He targeted companies and arranged for them to become infested with insects, then offered his services as an exterminator. This enabled him to plant listening devices and gather secret information.
After Dick Tracy and the MCU dismantled the spy ring operated by Big Brother, Bugsy became worried that Big Brother's documents would reveal the connection between them. Bugsy was determined to avoid being implicated alongside Big Brother, and he murdered an informant by exposing him to a lethal dose of concentrated insecticide while being held in protective custody at police headquarters. Bugsy then attempted to resume his industrial espionage operation, targeting one of Diet Smith's factories. His activities were discovered, and he was arrested.
