A homage to stories and characters that have endured for thousands of years, Hades' protagonist, Zagreus, was unknown to many players before their experience of the game. Unlike Zagreus, there are many well-known figures from Greek mythology in Hades, such as the Olympians and the spirits of the Greek heroes that populate the Underworld and play a role in Zagreus' journey. Thanks to the indeterminate time period Hades takes place in, Hades 2 has the freedom to continue in this tradition and feature other heroes from any point in Greek mythology.
