Odin appears in Eivor's visions in Assassin's Creed Valhalla.
Assassin's Creed Valhalla includes vision sequences in which Eivor encounters figures and stories from Norse mythology. Odin, also called Havi in the game, is especially important to these sequences and to the narrative's exploration of identity, fate, and memory.
Valhalla was released in 2020 and follows Eivor, a Viking who leaves Norway and helps establish a settlement in England. The game combines ninth-century historical events with mythological episodes presented through the series' science-fiction framework.
Thor, Loki, and Tyr are also important figures in Norse mythology and may appear in the game's broader mythological material, which makes the question easy to confuse. Odin is the specific god associated with Eivor's recurring visions and the Havi identity.
