Lee and Buscema find yet another way to dupe the poor Silver Surfer.That seems to be a recurring theme in this series.
This time Surfer gets duped by a mad scientist named Dr. Kronton who has created a one man army corps called Doomsday Man. Literally, this is a robot killing machine. It’s gone rogue in an underground silo and he needs Surfer’s assistance in tracking it down.
The diabolical plan is to have Surfer no only free the Doomsday Man, but to have the robot carry a cobalt bomb into the United States. If Dr. Kronton doesn’t get what he wants, well, there will be a hole lot of beachfront property in southern Canada.
And yes, there actually was a cobalt bomb. I thought it was a bunch of grandiose Stan Lee verbiage, but I was wrong.
Once Silver Surfer finds out Dr. Kronton’s plan, he is able to stop the Doomsday Man which is on a crash course to Manhattan, just like every other Marvel villain from this period. He does that by throwing the robot into the earth’s core and heaving the bomb into space where it safely explodes. During all this chaos, Kronton dies off panel. I assume it was a heart attack. It ends with everyone blaming Surfer for all the chaos and Kronton’s death as he walks away sad, thinking that these people are monsters.
