Easily one of the most important, game-changing issues of Thor ever. So far, the character has been decent, but hasn’t shown the level of depth of Spider-Man and hasn’t been written anywhere close the level of Fantastic Four. But in his third outing, we see Asgard, some of its residents like Heimdall and some of the lesser Asgardians, but not Odin yet, learn about the Rainbow Bridge…
…And watch Loki skip across.
…and meet Loki for the first time.
We also learn that only Thor is capable of lifting the hammer Mjolnir.
(But the hammer does not have a name yet.)
