Although Odin was heavily referenced in 2018's God of War, he never showed up in the game. However, the character will finally appear in God of War Ragnarök, and Santa Monica is expected to unveil Odin in the next trailer of the game.
While the character was not yet shown in any trailer or a screenshot, the studio started to tease him saying that Odin was the hardest character to design.
The fact that Santa Monica's developers had the most difficult time working out the design of Odin in God of War Ragnarök, was revealed by the art director of the game, Raf Grasseti, who as pointed out by the God of War subreddit, started answering questions about the game on his Instagram.
According to Grasseti, he and concept designer Dela Longfish spent a lot of time creating the character. The art director also added that he can't wait for people to finally see Odin.
