Thor (And Other Asgardians)
This one seems a bit obvious, but it would be negligent not to mention that Thor, Odin, Loki and other prominent Asgardians were part of Norse mythology long before they graced the pages of Marvel Comics. Of course, Marvel certainly took its fair share of liberties when it transformed these Norse gods into its universe, though things like Thor’s hammer Mjolnir and his rivalry with Loki were both worked in. Neither are probably an adaptation someone well-versed in Norse mythology could get behind in terms of accuracy, but there’s no denying they’ve both kept the names relevant in recent years.
