Hercules is shown to be tough, yet caring, willing to withstand hours of intense training at the hands of his mentor, Phil. He has a genuine love for Megara, and is willing to sacrifice even his own life for her. He is not without fault, however, as insults from Hades and a series of tough matches, including a loss to the Hydra, cause the hero to doubt his worth. It is when his friends' lives are most in danger that Hercules realizes he is not worthless, and that, in his words, "A true hero is measured by the strength of his heart."
