In Disney’s Hercules, what is the name of the river of the dead ruled by Hades?

In Disney’s Hercules, Hades rules the River Styx, the river of the dead.

The River Styx appears in the Underworld, where Hades governs the dead and plots to overthrow Zeus. In Greek mythology, the Styx is a boundary between the worlds of the living and the dead, and gods swear especially binding oaths by it. Disney’s film adapts these ideas in a colorful, comedic way rather than presenting a strict retelling of every myth.

The animated Hades is voiced by James Woods and is written as a fast-talking underworld ruler. The film also includes the Fates, the three women who share one eye, and the boatman Charon in its myth-inspired imagery. The Acheron and Lethe are also rivers associated with Greek mythology, which makes the exact name a common source of confusion.
