John James Rambo is a fictional character in the Rambo franchise. He first appeared in the 1972 novel First Blood by David Morrell, but later became more famous as the protagonist of the film series, in which he was played by Sylvester Stallone. The portrayal of the character earned Stallone widespread acclaim and recognition. The character was nominated for American Film Institute's list 100 Years…100 Heroes and Villains. Following the success of the first movie, the term "Rambo" was occasionally used in media circles to describe a lone wolf who is reckless, disregards orders, uses violence to solve all problems, enters dangerous situations alone, and is exceptionally tough, callous, raw and aggressive.
