|“||In the darkness, Morpheus, the God of Dreams, awakened to a world where he and only he wielded power.||”|
Morpheus ("shaper [of dreams]") in Greek mythology as the god of dreams, leader of the Oneiroi. Morpheus has the ability to take any human form and appear in dreams. His true semblance is that of a winged daemon, imagery shared with many of his siblings.
In God of War series
God of War: Ascension
He doesn't seem to be so powerful, however, since he never appeared personally in the series and may have even been killed by the other gods for his crimes after Chains of Olympus . Another hypothesis is that, although he was a Primordial, he was younger than the rest of them, and may have been hidden by his father, Hypnos, when he was still very young, like what happenned to Zeus.
God of War: Chains of Olympus
In God of War: Chains of Olympus, he took advantage of Helios' disappearance by casting the Gods and mortals into a deep slumber and began enveloping the Earth in a black fog. He then unleashed his minions such as Shades, Banshees and Morpheus Beasts upon the land. However, Morpheus had to retreat when Kratos returned Helios to the sky. Morpheus himself was never shown or appeared in any way in the game itself, being only a background character (even though a major antagonist for the first half of the game). It is unknown if Morpheus suffered any consequences for his actions.
God of War III
A costume entitled Morpheus Armor appears as a skin for Kratos, but the god of dreams does not appear himself, so what he looks like still remains as much a mystery; yet the armor and black eyes of the skin may give an idea on his appearance.
Although Helios dies at the hands of Kratos, it is not indicated whether Morpheus takes part in the chaos following the sun being blocked out. Either because Morpheus is avoiding the god's conflict or Morpheus' power unspokenly does spread along with the other disasters. It is posssible the Morpheus perished by the ensueing chaos around the world.
