Heroic Age (ヒロイック・エイジ, Hiroikku Eiji) is a Japanese science fiction mecha space opera anime originally conceptualized by Tow Ubukata. The series first aired on TV Tokyo on April 1, 2007 and ended on September 30, 2007, with 26 episodes. On July 23, 2007, a manga adaptation began serialization in Kodansha's Magazine Z. Though the story is the same, it is told from the point of view of Iolaous. Five official guidebooks were also published and had consecutive monthly releases from July to November 2007. The story's theme is based on stories in Greek mythology, especially those surrounding Heracles, upon whom the main character is based, and his Twelve Labors. Many of the other characters are also based on Greek mythological figures; characters share similar names to their Greek counterparts, and how their relationship is defined with others correspond with Greek stories. The title of the series, Heroic Age, is also a slight testament to the similarities to Greek mythology, referring to the time of the Heroic Age. The tribes featured in the anime are loosely based on Hesiod's Five Ages of Mankind.
