So, Thor: Ragnarok has Hela and Fenris-wolf, who are both Loki’s children in mythology, if not in the Marvel mythos, and who play a role in mythological Ragnarok.
Absent, however, of Loki’s mythological brood and the monsters of Ragnarok is Jormungand, the world-serpent – who in mythology, kills Thor in Ragnarok by piercing him with its fang.
Now, obviously Thor doesn’t die in the film and doesn’t battle with the world-serpent.
But–
He does get pierced by a snake.
Specifically, a stabby little shit of one who goes “Mblergh, it’s me!”
Oh wait, are those Thor’s harem pants in the second gif? I couldn’t tell who that was. And is he stepping over dead Asgardians…? Escaping from Hela only to run into Thanos is a real ‘out of the frying pan, into the fire’ kind of situation…
I’m pretty sure that Frigga is not Hela’s mother… I suspect that marrying Frigga was part of what put Odin off his conquering ways. I do wonder who Hela’s mother was, though, and what kind of relationship she might have had with her new stepmother. Kind of a reverse wicked-stepmother situation, I guess…
