Big Jim was a popular line of action figure toys produced from 1972 through 1986 by Mattel for the North American and European markets. In Latin America he was renamed Kid Acero, and for a short period of time, Mark the Strong in Europe. Originally inspired by G.I. Joe, the Big Jim line was smaller in size (closer to 10 inches in height compared to Joe's 12) and each figure included a push button in the back that made the character execute a karate chop action. The action figure's arms were made of a soft plastic/vinyl material and contained a mechanism that simulated the bulge of a biceps when the arm was bent. Big Jim was less military-oriented than the G.I. Joe line, having more of a secret agent motif, but also had a large variety of outfits and situations available including sports, space exploration, martial arts, hunting, western, camping and even unusual choices such as fishing and photography.
