G.I. Joe: Sigma 6 is a line of military-themed action figures and toys produced by Hasbro re-imagining the characters of the 1980s toyline G.I. Joe: A Real American Hero.The Sigma 6 toy line served several purposes for Hasbro. First it allowed them to depart from the classic 3 ¾-inch format of the A Real American Hero series of the 1980s; most Sigma 6 action figures stand at approximately 8 inches (200 mm) and have more articulation.
