Tales to Astonish #93

As Namor battles It, torpedoes from the submarine cause an avalanche, trapping It. Namor turns on the submarine and begins to punch holes in it. It (the creature) returns and they battle, further damaging the submarine and (apparently) killing It. The submarine leaves (with the carcass of It) while Namor breaks off, feeling weakness overwhelm him. Namor makes it back to Atlantis where the advanced medicine saves his life from a massive dose of radiation. Improving, he vows to summon a council of War!
