In God of War (2018), what is the name of Kratos's son?

In God of War (2018), Kratos's son is named Atreus.

Atreus travels with Kratos through the Norse realms after the death of his mother, Faye. Their journey begins as a mission to scatter her ashes from the highest peak in all the realms, but it becomes a much larger conflict involving gods, giants, and ancient prophecies.

Atreus is initially presented as a young archer who is still learning to survive beside his powerful father. His ability to read languages and use a bow makes him important during exploration and combat. The story also reveals that he has a second name connected to his giant heritage: Loki.

This name causes a common mix-up. Atreus is Kratos's son, while Loki is his name among the giants; Loki is not a separate companion or another character in the game. Atreus returns as an older teenager in God of War Ragnarök, where his search for answers drives much of the plot.
