Atreus

Atreus is the son of Kratos and Faye. He is incredibly adept at learning languages and using magic. His mother taught him all about the Norse gods and myths. She also taught Atreus to hunt and speak many languages. He accompanies his father on a journey to spread his mother’s ashes at the top of the highest peak in all the realms.

Atreus’ lineage is fascinating. His father is a god, while his mother was a giant. Faye wanted to name Atreus Loki, but Kratos chose his given name based of a Spartan warrior he knew. Since Atreus is Loki, it opens up possibilities based off Norse myth.

Loki is the father of the World Serpent. This would explain why the World Serpent recognizes Atreus during their journey. Since the World Serpent was sent back in time during its fight with Thor, it is quite possible that Atreus will grow up to create the World Serpent in this timeline. You can see this prophesy on the walls in Jotunheim at the end of the game.
