Plastic Man first appeared in Police Comics #1 in August 1941. Police Comics was an anthology series published between 1941 and 1953 by the defunct Quality Comics. DC Comics acquired Quality Comics in 1956.
According to DC comics, “Pop culture’s silliest superhero, Plastic Man is as much a humor icon as a heroic one. During a heist gone wrong, petty crook Patrick “Eel” O’Brian was doused in chemicals, allowing him to stretch his body into any shape he desires. Nursed back to health by altruistic monks, he was inspired to embrace life’s brighter side.”
