Even the most diehard fans of Marvel Comics and the Marvel Cinematic Universe can’t claim to know the real Loki - as in, the Loki of Norse mythology. In fact, so many differences crop up whilst comparing the Norse Loki versus the Marvel Loki that he becomes almost unrecognizable to one only familiar with the works of Stan Lee and Jack Kirby.
The traditional Loki is not necessarily a Norse god at all, nor is he Thor’s brother or the adopted son of Odin. Instead, he’s an ambiguous figure with ambiguous morals who typically stands as an ally of Asgard - before ultimately betraying them and bringing about their end via Ragnarok.
All accounts seem to agree, however, that the mythological Loki was at least as charming as Tom Hiddleston, if not more.
