Rob is shown to be a very righteous and dedicated man who cares deeply for his allies, such as when willingly stays behind to hold off the trolls chasing Silver in Chapter 6. He is also fiercely determined to rescue Fudd, a man who he had barely known, from the trolls simply because he made a promise to himself that he would get him back. This promise would even give him the willpower to rise from the brink of defeat during his battles. Rob also appears to be quite intelligent.
