Atom Blake is a scientific wizard, with all sorts of fantastic abilities. He is being raised by his Aunt Nora and Uncle Joe when he realizes he's not like the other kids. He's as strong as several men, fast, and a mental marvel. When he asks his Uncle Joe about it, he finds out that Joe was best friends with Stuart Blake and Blake left a coded message for Atom. Atom is able to read the code that tells him how his father and mother were scientists and created a metal that was bonded with all the known elements to make energy available to mankind. However, exposure to the rays given off kill an ape, and the Blakes realize that someone would have to be slowly treated to handle the rays. They begin the treatment on their son. The rest of the message outlining the source of the element and his parents' fate is missing. Also left for him, is a magical ring with an inscription in the same mathematical code as his father's message. All he has to do is make a wish, and the ring makes it happen.

Atom was able to fly using "heel rockets", armed with "atom pellets", he also used ray guns, and an iridium sword that destroyed all it touched. Atom and Elektra are from the year 2000 (which at the time of this story being published was considered to be far in the future). Where they got their powers from is unclear - in fact the abilities they display may be typical of your average youth in the year 2000 A.D. The two are called on whenever the world discovers threats to the human race, being sent in to battle the enemies of mankind.

After the war Professor Josiah Rhonne is looking for a way to end the threat of nuclear annihilation. His idea is to work on transforming people, by changing their atomic structure and making them immune to radioactivity and nuclear explosions. He needs a human test subject, so chooses William "Willy the Wharf Rat" Burns, who was brain damaged by a Nazi torpedo. An explosion in the lab accidentally transforms Willy into the Atomic Thunderbolt, and he fights crime with his new powers. He can fly and project "atomic energy" blasts.
