POSEIDON Profile and Backstory

Personality

POSEIDON is presented as having no hostility toward humans whatsoever. This is particularly noticeable when Aloy retrieves it and offers to bring it home to GAIA.

Horizon Zero Dawn

POSEIDON was one of the first subordinate functions deployed after MINERVA's functions were complete, working along with machines created by HEPHAESTUS to purify the various oceans, rivers, and lakes on Earth.

Horizon Forbidden West

When HADES was infected by the Mysterious Signal, GAIA destroyed herself to prevent it from taking over. During this period, a deranged and semi-conscious POSEIDON fled to a processor somewhere in the Forbidden West. Aloy obtains POSEIDON in the main quest The Sea of Sands, where she discovers it in a vast desert area, buried in the underwater ruins of Las Vegas.
