God of War IIIEdit
Battle with the HippocampiEdit
At the beginning of the game Kratos goes inside Gaia via a wound inflicted by a Hippocampi, and comes across the Titan's heart while trying to find a way out. The heart chamber has a movable pillar with climbable vegetation, and each wall has a socket to place the pillar in, allowing Kratos to climb upwards. The left wall leads further into Gaia's body, and the right wall leads to a small alcove with a hay bedding and a childish drawing of what looks like a person. It is implied that this is where the young Zeus was raised by Gaia (further hinted at by the presence of Zeus' Eagle in the chamber).
Battle with ZeusEdit
When Kratos and Zeus leap into Gaia's body to evade death at her hands, they wage their final battle in front Gaia's heart. Kratos destroys the heart's defenses with the Nemean Cestus and the Bow of Apollo, causing Gaia great pain, before attacking it again to regain his strength, causing Gaia even more pain in the process. Both Kratos and Zeus take advantage of Gaia's open heart throughout their final battle until Kratos uses the Blade of Olympus to stab both Zeus and Gaia's heart, thus killing Gaia and wounding Zeus.
- Gaia's heart looks and sounds like a human's heart, pumping an unknown substance, possibly as equally important as blood, through a vast piping of branches within her body. Her heart has the form of a tree.
- On the cliff to the right, the Godly Possession, "Zeus' Eagle" can be found.
- The yellow blood-like substance in Gaia's heart is also seen when Kratos cuts Gaia's hand, and when he kills Cronos by stabbing the Blade of Olympus through his forehead. This implies Titans' blood is differently coloured, likely a representation of ichor (which was in fact the blood of the Gods also), although when Kratos injured Cronos' arm and stabbed his jaw with the Onyx shard, the titan's blood was red, though this may just be an oversight.
