Gilgamesh is extremely manipulative, egocentric, and selfish, claiming that everything in the world is his possession. He is unable to acknowledge anyone's authority. He is incredibly proud, especially of his treasure collection. He has traits of vampires, sun doesn’t burn him but much exposure does. Vampire bites do not turn humans into vampires. If he doesn’t drink blood in 12 hours, he’ll become sickly. He doesn’t look like a vampire at first, not revealing it right away.
