Laufey leads the Frost Giants in a plot to take over the Nine Worlds. Upon confronting Laufey, the Agents of S.M.A.S.H. and Thor end up subdued by the cold winds and captured. Laufey arrives revealing his plot and even commented that he doesn't know what Thor sees in the humans. She-Hulk breaks free from the ice and frees Thor and the Hulks as Laufey gets away. After defeating the three-headed Ice Serpent, the Agents of S.M.A.S.H. and Thor arrive at Laufey's lair as Laufey unleashes his ice creatures on them. Following the plug-up of the ice, Laufey states that they have helped to free Ymir who will help bring an endless winter to Earth. Thor engages Laufey in battle while the others work to fight Ymir's weak spot. Laufey states that as Earth grows cold, his power increases. After Red Hulk's heat had helped to defeat Ymir, Laufey retreats back to Jotunheim.
It is revealed that Leader tipped off Laufey on where he could find Ymir.
