Description
Odin sends Thor to search for Loki on Earth. There, Loki traps Thor with the Living Mask which mystically switches their faces and powers. Balder and Sif arrive to find Thor (who looks like Loki now) raving that he is Thor, until he finally convinces them of who he is by not slaying Balder when he has the chance.
