Zelgadiss is probably around 19 or 20, but he ages at half the speed that humans do due to his condition. He was likely turned into a chimera when he was 15 or 16 years old. His height is 178 cm (5'10"); he weights between 80-90 kilograms as a chimera, and was 60 kilograms before his transformation. In the series, Zelgadiss says that Rezo is either his grandfather or great-grandfather, but Hajime Kanzaka later decided that Rezo is his great-grandfather only (the rumor that Rezo was both was a result of bad translations). ==Abilities==
