Freya's brother in God of War Ragnarök is named Freyr.
Freyr is a Vanir god and the leader of a group of resistance fighters encountered during the Norse-era story. He has a close family connection to Freya, who is also a powerful Vanir goddess and former queen of the Valkyries.
The game presents Freyr as a charismatic but imperfect leader who has built a new community after breaking away from the Aesir. His role expands the story's exploration of the conflict between the Vanir and Aesir gods.
Freyr should not be confused with Baldur, who is Freya's son and a major antagonist in God of War (2018). Týr is a different Norse god associated with justice and war, while Heimdall is an Aesir guardian. These distinctions matter because Ragnarök includes many related gods from Norse mythology.
