Thor den mægtige #1/1974

In "Kilden ved Jordens rand!", Thor and the Warriors Three clash with the forces of Satrina and Kartag—only to find unexpected kinship in the midst of battle. As Asgard trembles under the onslaught of Mangog, who lays waste to the realm, Thor must unite with his former foe Kartag to stand against the unstoppable threat. With Odin near death from the strain of shielding Asgard, and Hildegarde joining Sif in a fierce defense, the fate of the realm hangs in the balance.

When a massive alien giant is discovered frozen in a glacier, panic spreads over the possibility of what might awaken. Scientist Charles Burton, convinced the fear is more dangerous than the creature itself, takes the risk of freeing Zog—only to find the giant is far less threatening than anyone imagined.

In a grim, underground arena, the merciless fighter Crusher learns the hard way that even the strongest can be overpowered—when the monstrous Xoorr emerges, proving that pain has a new, far more terrifying master.
