Description
During a battle in which Thor defeated the troll Ulik as save the Norn Queen Karnilla, Loki was able to steal Thor's enchanted hammer. Without the Hammer, Thor will return to the form of Dr Don Blake at the end of sixty seconds. He pleads with Karnilla, who uses her magic to transport himself and Sif to earth. On earth, Loki in human quise is stopped by a policeman. Thinking that the Loki may be a thief they are looking for, he demands to see the content of the package Loki is carrying. He opens it to reveal Thor's hammer. When the policeman lifts it from Loki's hand, the enchantment of the hammer makes it too heavy to be held. It falls to the sidewalk. As Loki lifts the hammer, it suddenly transforms back into Dr Blake's cane. Loki realizes that means that Thor has also transformed, and after switching to his Asgardian garb, goes in search of his brother. Rounding a corner, he finds Sif and Thor in his human form as Blake. Sif attacks Loki with her sword, but is unable to overcome him. He grabs her and tosses her into Blake. He then blasts Sif with a mystic Norn bolt. Blake then attacks Loki, and uses his coat to entangle Loki's hand that holds the cane. When Loki attempts strike Blake, Blake manages to get the cane away and taps it on a nearby wall transforming back into Thor. After a brief battle, Thor is able to capture Loki by twisting a traffic sign pole around him. He then rushes to where Sif lays severely injured. Tapping his hammer, he reverts to his Dr Blake form, hoping that his physician training can save his beloved. Meanwhile in Asgard, Balder reveals that he knows Karnilla only sent Thor and Sif to earth in the hope that they would be killed. He wants to draw his sword and attack her, but is unable to bring himself to attack a woman. While in the pit behind them where Thor dropped Ulik, the troll is able to grab an ledge and stop his fall. Above the ledge he sees a cave with a blinding light, and enters to see what mystery lies within. In the operating room of City Hospital, Blake prepares to operate on Sif, concerned that he might not be able to finish the delicate operation before Loki finds him again. Finally managing to free himself, Loki uses his stolen Norn magic to turn invisible and goes in search of Thor. He learns from the mind of a passing policeman that Blake has taken Sif to the hospital. He uses his magic to fly to the building and breaks in through one of the operating room windows. Blake has one of his assistance spray an ether tank at Loki while Blake clears the operating room. Then tapping his cane, Blake transforms into Thor and tosses himself and Loki through the hospital and out to where they can fight. A furious struggle results from Thor's strength against Loki's Norn magic. Odin watches with displeasure from Asgard. He growls that the battle must come to an end, because he will need the power of both his sons to stand against the new evil that endangers Asgard. Using an Odin bolt, he separates the two sons, and orders an end to the battle. With a threat, Loki disappears, and Thor wonders what new danger is menacing Asgard.
