The Hulk has been around for 51 years. In that time, he’s become internationally famous, with “Hulk” becoming a standard word for strength and anger and a giant green guy who smashes things. But, surprisingly, the Hulk was actually originally canceled. After his debut in 1963, Marvel only managed to publish six issues before they were forced to cancel The Incredible Hulk due to a lack of enthusiasm from its readers. One possible reason that the Hulk was canceled is that he was quite an inconsistent character in those early days. In some issues, he was an intelligent, good-natured hero; in others, he was a fast-talking criminal. After being canceled, the Hulk started turning up in other comics as a villain, got a guest spot on the Avengers, and gradually became the Hulk we know today, getting his own comic once again.
