After Ares traps the cadets in a nightmare with Morpheus' help, Hercules's dark side is set loose and causes havoc in the nightmare. Rather than destroying him, a situation where he would end up destroying himself in the process, Hercules has to embrace the fact that this part of him does exist. In Forgery, this darker side is seen again after Hercules uses the Fire From The Heart Of The Earth to change his personality. Unlike the real Hercules, his evil counterpart seems to thrive on chaos and does not particularly care if he hurts anyone. If anything, he seems to enjoy causing pain.
