In many different myths and legends, the raven had become associated with dark and evil things, such as trickery, ill omens and death.
In Germanic mythology, Odin was often associated with ravens. Odin has pair of ravens, Huginn (from the Old Norse for "thought") and Muninn (Old Norse for "memory" or "mind") that fly all over the world, Midgard, and bring the god Odin information. Huginn and Muninn are attested in the Poetic Edda
In the God of War series
God of War: Ascension
In the public demo, after defeating the Hecatonkheires for the first time, Kratos ends up in a sewer. As he leaves the sewer, we see several prisoners in cages, hanging above an abyss. As Kratos climbs his way to temple, we see how a raven causes one of the cages to drop, sending the unfortunate prisoner to death.
God of War: Ghost of Sparta
Throughout God of War: Ghost of Sparta, Kratos encounters flocks of Ravens, who serve as winged servants of Erinys and Thanatos. They frequently appear in flocks, and attack Kratos by quickly swooping at him, and delivering fast, weak attacks. Kratos can instantly destroy these winged adversaries by grabbing them, throwing them to the ground, and crushing them with his foot.
God of War II
Raven is a gigantic black bird. Ravens attack Kratos during both times when he's flying on the Pegasus. The Raven can quickly fly itself into Kratos and the Pegasus, forcing them to fall into a tailspin which Kratos must then quickly recover from. Kratos can slay a raven by slamming head-on into it, leaping onto its back, and finally grabbing and breaking its neck.
God of War III
Ravens or crows are the enemies that appear only in Challenge of Exile - Old Birds.
God of War (2018)
Ravens are the ambient creatures in any realm, especially in Midgard. One of the icy ravens (known as Eyes of Odin) is summoned by Odin to observe the world and gather information for him. Kratos can destroy these ravens.
- The Raven as a giant bird in God of War II, is more likely based on the Persian myth of the roc (Rukh), a giant bird able to lift elephants. Another possible but less likely inspiration could be the Thunderbird that appears in certain North American indigenous peoples' history and culture.
- In God of War (2018), there's an Easter Egg, ravens/crow has three-eye throughout the other realms possibly reference of Three-Eyed Raven in Game of Thrones.
