I just got a subscription to Marvel Digital Comics (:) and started reading the back-stories of Thor and Iron Man. Some of the early Thor villains are creepily cartoonish, like the Executioner, who is a perfect Red Scare caricature of a Communist leader and weird magicians like Sandu and Merlin. But Loki IMHO is like the Joker of the Marvel Universe. He's physically weaker than Thor but is like Mystique on steroids and can make dragons pop out of nowhere and make people look like Mr. Game and Watch. Even though in the 1960s comics, good is always supposed to win, Loki manages to screw stuff up even while tied to a rock in Asgard. Jane Foster is a little weak as the main female heroine, like when she tells Thor to stop chasing Cobra, but a lot of the early Marvel Comics were kinda sexist (see X-Men #1). So that shouldn't be a problem as I get closer in the modern age. What are some of your favorite Thor comics?
