Odin is the former chief deity of Norse mythology and leader of the Gods in Asgard. He wields the legendary lance Gungnir.
As the former chief deity of Norse mythology, Odin has the appearance of an elderly man with long, grey hair, and a matching beard. He wears an eyepatch over his left eye.
Despite being a God, Odin is very perverted, harassing young women and going to "Oppai Clubs" for fun. He also has a tendency to make fun of his bodyguard, Rossweisse, who greatly disproves of his perverted antics. He calls her "the Valkyrie whose age is equal to the number of years without a boyfriend". Odin, however, is not completely irresponsible, proven when he felt like he brought trouble to Issei and his friends when Loki attacked. He even broke the rules of his religion and came to the outside world in hopes that the young ones in his religion will ponder their future and prepare a new path for the religion and for themselves.
Not much is shown of Odin's past except for the fact that he is one of the Gods that have been active since ancient times and gave away his left eye to the Mímisbrunnr. He is the Ruler of Asgard and dwells in his fortress Gladsheim, where he welcomes the fallen ones which were brought by the Valkyries to his realm. He took Rossweisse as his bodyguard some time before the start of the series.
Odin first appears near the end of Volume 4, commenting on the death of the God from the Bible and how the Christian religion became a children's playground (referring to Sirzechs, Azazel, and Michael), but claims that it is interesting to see what these youngsters can do without God.
In Volume 7, Odin, with Rossweisse and Baraqiel as his bodyguards, encounters Issei and Akeno during their date. He later goes into the Hyoudou Residence announcing his visit to Japan, telling Azazel that he had "trouble at home" and about the increasing numbers of Balance Breaker users in the Khaos Brigade, before leaving with Azazel to go to an Oppai Club. When Loki came to Issei's town, condemning Odin for falling so low to consort with other mythological systems, Odin replies by saying that he enjoys talking to Sirzechs and Azazel more than he does with Loki and wants learn more about the Japanese Shinto, and that the Japanese Shinto are also interested in their Yggdrasil, wanting both sides to negotiate peacefully and start cultural interchange. He later has a private conversation with Azazel, stating that he feels sorry for bringing trouble to the Gremory and Vali Teams, hoping that his actions of coming to the outside world will open a new future for the youngsters in his religion. After the battle against Loki, Odin leaves Rossweisse in Japan.
In Volume 16, it was stated by Azazel that Odin wants to take Vali Lucifer as his adopted son in order for the Vali Team to be pardoned for their crimes and affiliation with the Khaos Brigade; in which Vali agreed to.
