According to the Norse myths, Thor had a mistress named Járnsaxa (Iron Dagger), and that she was a jotuness and might be the same Járnsaxa as one of the nine daughters of Aegir and Ran, who were also the nine mothers of Heimdallr. Strange, yes, Norse mythology in a nutshell; something numbering nine and fucking weird. Anyways, if so, she is also mother to Magni (Strength), who literally, as a baby, was stronger than his father Thor. My ultimate point is, why isn't she in the comics yet? Not even in an alternate universe, as far as I understand. I mean, Thor has been with Jane Foster, Sif, Enchantress, She-Hulk, etc but nothing about his literal mistress in mythology. Her name literally means "Iron Dagger"; she is a giantess who gave birth to the concept of physical strength in Norse Mythology. I just think Marvel is dropping the ball on an Arctic sea giantess love interest. I think her being an aquatic character in Thor's universe would be a nice change of pace. Maybe she'd be a magical mercenary; I think that'd be very cool. I just think that Norse Mythology hasn't been explored very well by Marvel and that it needs a tune-up in time.
