Tales to Astonish #92

When a passing ship dumps a radioactive barrel into Namor's realm, he realizes the danger it poses and takes it far away from Atlantis to throw it into a deep crevasse. Little does he know that the radiation in the barrel has awakened an ancient monster who begins to menace both the surface world and the world beneath the waves alike. Thinking the monster another surface threat, Namor begins to battle it as a nearby submarine, who is also tracking the radioactive creature, begins firing torpedoes at the both of them.
