Loki has the appearance of a handsome man with eyes like a delinquent. He has light blue hair that floats behind him with two small bangs. Loki also has a blue jewel on his forehead and yellow earrings.
He was stated to be wearing a robe similar to Odin's except with slightly different ornate markings in the Light Novels. In the anime, his robe is white.
Loki is an arrogant and overconfident man, who appears to enjoy destruction as he desires to start Ragnarok (the end of the world) by killing Odin. He also enjoys fighting as shown during his battle against the Occult Research Club and the Vali Team.
Loki also thinks Odin is making a mistake by forming an alliance with the mythology of the Bible and shows hatred against Christianity as they spread their religion on their soil.
The evil God of Norse mythology, Loki married the Giantess Angrboða who gave birth to his two sons: Fenrir and Midgardsormr. Loki also transformed a Giantess into a wolf for his son, Fenrir, to mate with which eventually gave birth to his two grandsons: Sköll (スコル Sukoru) and Hati Hróðvitnisson (ハティ Hati).
Loki appears in Volume 7, intending to murder Odin and cause Ragnarok. In his initial battle against the Occult Research Club, he was able to overwhelm them with his son, Fenrir, but decided to retreat after seeing the Vali Team, claiming that it is enough to see the Two Heavenly Dragons together. In the final battle against both the Gremory and Vali Teams, Loki summoned Fenrir's sons, Sköll and Hati Hróðvitnisson, and many Midgardsormr knockoffs to attack them which were easily disposed of. Loki was defeated after Issei gained access to the imitation Mjölnir (courtesy of the Breast Fairy), adding with the Holy Lightning of Baraqiel and Akeno and allowing them to defeat Loki. After his defeat at the end of Volume 7, he was placed under many layers of sealing by Rossweisse.

- Curse: In the anime, Loki cursed both Issei and Rias following his defeat. The curse takes advantage of the person's negative feelings and plays a major role in High School DxD BorN.
