Genesis's physical appearance is based on Gackt, who is one of the most famous Japanese Pop/Rock idols. Gackt also wrote and performed Dirge of Cerberus's theme song, "Redemption" and actually wears the Genesis costume in the music video, though his hairstyle has changed. In the Game: Crisis Core's beginning portrays Genesis as a deserter, arrogant and childish. He even plays a trick on Zack after they meet in Banora. At first, he seems to be a simple character, but as the story progresses, the conflict within Genesis becomes increasingly visible.
