Plastic Man was a crook named Patrick "Eel" O'Brian. Orphaned at age 10 and forced to live on the streets, he fell into a life of crime. As an adult, he became part of a burglary ring, specializing as a safecracker. During a late-night heist at the Crawford Chemical Works, he and his three fellow gang members were surprised by a night watchman. During the gang's escape, Eel was shot in the shoulder and doused with a large drum of unidentified chemical liquid. He escaped to the street only to discover that his gang had driven off without him.
