Nathaniel Adam (New Earth-Eight)

Life and Death of Nathaniel Adam
Nathaniel Adam was born in a small town in Maine, where shortly after graduated he joined the U.S. Air Force and was based in Arizona. During this time, he would meet and eventually marry the love of his life, Angela Adam.

The two would be together for many years, during which time he would father two children with her, his son Randall Adam and his daughter, Margaret Adam.

For several years, Nathaniel would live in idle happiness, but this would change after he was framed for spying and selling government secrets to foreign governments in 1996. He would be forced to face execution for the crimes, but was given the option in participating in an experiment testing the durability of an alien ship when exploding a nuclear bomb blow it in exchange for a pardon. Knowing the risk, Nathaniel agrees and proceeds with the test.

During said test, Nathaniel would become encased in the metal of the ship after the nuclear weapon exploded. After this occurred, Nathaniel was converted into energy and launched several years into the future, while everyone else who observed the experiment assumed he perished.

Captain Atom
Nathaniel would return 20 years later, as he reconstructed himself as an energy being. Afterwords he would put under the watchful eye of General Wade Eiling and Doctor Heinrich Megala, who used his powers as a government sponsored Superhero, known as Captain Atom.

As Captain Atom he would go on to fight multiple super-villains and even joined the Justice League International. During this time, Nathaniel would discover that his family perished in a car accident 10 years before he returned and he began to grow very distant from people. His condition would worse and he would develop suicidal tendencies, where he began to take more unnecessary risks. This would come to ahead, when he apparently sacrificed himself from stopping a nuclear apocalypse from occurring.
