History has had its fair share of hero's and villains, both real and not. These include the likes of Iron Man, Superman, Spiderman and Captain America. Real life hero's consisted of Wyatt Earp, Sitting Bull, King Arthur and Ivanhoe. In any case, these men and woman have their own set of goals and would put their lives on the line for them. Whether bad or good, they have always stood for what they believed and time has tested them, always proving them true in the end. While not all of them are good or noble, they are the World's Greatest.
