Loki

Loki is the primary antagonist of Valkyrie Profile. Loki is a half-Aesir and half-Vanir. While allowed to live in Asgard, Loki is not held in high regard and constantly suspected of being up to no good. Odin and Freya sealed his power, Loki has an adult or vanir appearance once he obtains the Dragon Orb. The only Aesir he is seen associating with is Frei. Frei appears to honestly see Loki as a friend, and in the manga she is devastated when Loki turns against Odin.
