Synopsis for "The Monarch and the Monster"
Namor continues his battle against the radioactive creature known as It, as a military submarine, believing Namor to be responsible for the creatures attack on the vessel fire torpedoes at the two combatants. Their fight knocks them away from the blast, however, It's radiation begins to sap at Namor's strength.
As the exploding torpedoes cause an avalanche, It get's buried in the rubble and the Sub-Mariner just barely makes it out. Thinking this was an attack on him by the soldiers in the submarine (whom Namor believes sent It is a robot sent to attack Atlantis by the surface dwellers), the prince attacks the sub. As Namor breaches the hull of the ship with a single punch, It manages to free itself and resume its attack on Namor before he can cause more damage to the sub.
Greatly weakened by the radiation, Namor dives out of the creatures way when it lunges at him, causing It to smash through the hull of the ship. When the soldiers aboard the sub finally get their scanners running they see the creature and realize that Namor wasn't the one attacking them all along and retreat from the fight.
Weakened Namor returns to Atlantis where he learns of his near lethal dosing of radiation. Having recovered thanks to the advanced medical technology within Atlantis, the Sub-Mariner survives. Greeted at his bedside by Lady Dorma, Namor tells her of his battle against the "robot" from the "surface world". Still believing that It was a robot sent to attack his nation, Namor orders that a council of war be organized.
