Summary

Born in the year 1,000,000 A.D. Future Man, went back to the year 1946 in order to conquer the past due to his Earth`s timeline being a planet of devastation. He decided to ally himself with Madame Death, a 1940`s crimboss, to achieve his goal.  
Madame Death and Future Man first tried to create a disease called the Green Plague Germ, which would kill hundreds when they would release it in the Swiss Alps, but they were stopped by Captain America and Bucky. 
They next went to the Diablo Center in South America and created the Slow-Down Machine, which paralyzed countless people, but they were opposed by The Whizzer. 
Then they went to the coast of China to create a tidal wave capable of destroying Asia, but they were thwarted by Namor the Sub-Mariner. 
Again they travelled, this time to Egypt, where they resurrected mummies using a device called the Life Battery, but they were stopped by Miss America. 
They then went to North America but ended up being thwarted by the Human Torch and Toro. 
Eventually they were confronted by the entire All-Winners Squad, and so they fought on Future Man's ship. Once again on the verge of defeat, Madame Death and Future Man tried to escape to the future, but Captain America ended up sabotaging the ship, causing Future Man and Madame Death to hurtle aimlessly into the past.  
Madame Death eventually managed to return back to the present after Future Man had spent years attempting to fix his ship. As it turned out however, Future Man perished from an ancient illness during that time, leading Madame Death to seek vengeance against the All-Winners Squad using what was left of Future Man's technology.
