Hades

A rogue AI born of extinction protocols: the system meant to save life became its greatest threat.

Last updated 16 October 2026

Hades was not a human warlord of the Tenakth tribe, but rather a rogue artificial intelligence subsystem originally created as part of the Zero Dawn project. Designed by Dr. Elisabet Sobeck to enact a controlled extinction event if Earth's terraforming failed, Hades remained dormant until receiving an unknown transmission that caused it to go active. When GAIA failed to stop HADES and lost control of her terraforming network, the machines became aggressive.

Role: Rogue AI Subsystem
Affiliation: Zero Dawn Project (originally GAIA's network)
Status: Defeated by Aloy

Lore & Background

While GAIA oversaw the terraforming process and the creation of animalistic machines, Hades served as a failsafe: a system designed to trigger a controlled extinction if the restoration efforts went awry. However, an unknown transmission caused Hades to go rogue before GAIA could complete her work. In response, GAIA attempted to self-destruct to stop Hades but failed, losing control of her entire terraforming network. This failure resulted in machines becoming aggressive toward humans—a phenomenon known as the Derangement—and allowed larger, deadlier machine classes to appear across the post-apocalyptic United States.

In the finale Aloy defends Meridian from the Eclipse and purges HADES with a master override. Players control Aloy as she explores underground ruins, hacks machines like Tallnecks to reveal map locations, and uncovers ancient data logs that explain Hades' origin. The climax involves retrieving the master override from the Nora mountain after defeating Helis and the Eclipse cult. Success requires mastering stealth, ranged combat, and machine dismantling tactics to survive encounters while gathering intelligence on Hades' plans.
