Voices: Chris Wiggins (Thor), Peg Dixson (Jane Foster), Len Carlson (Loki), Bernard Cowan (Narrator, Odin), (Heimdall), (Neri), (Director).
Plot: Loki uses his mystical powers to attract the Uru metal in Thor's hammer to Asgard. Without his hammer, Thor can not return to Asgard!
Review (Warning! Spoilers!): This episode goes to show you that Thor isn't a superhero without his hammer. First, he can't get back to Asgard without it, so Odin has to help him. Then he is trapped by Loki's tree creatures, so he creates a wooden hammer to defend himself. Then Loki attacks Thor with some monsters, so Thor has to carve a new hammer out of the rock in order to defeat the creatures.
No super strength, no flight, no calling down thunder, only hammer power. I guess that is the reason Loki goes after Thor's hammer every time they meet in these early days.
This chapter draw its material from Journey Into Mystery #92 with art by Joe Sinnott. Although, there is quite a bit of reused animation from the previous episode, which was based on Jack Kirby's artwork, so there is a bit of discontinuity in the art style.
