"Point Of Origin". Script by Cary Bates, pencils by Pat Broderick, inks by Bob Smith.

Captain Nathaniel Adam was a U.S. Air Force officer during the Vietnam War. Framed for a crime he didn't commit and sentenced to death in 1968. he agrees to participate in a military experiment in exchange for a presidential pardon (should he survive). The Air Force would detonate a nuclear bomb under a captured alien ship with Adam on board! Against all odds, he survives; the alien metal melds with his body, while the excess energy threw him forward in time nearly twenty years, granting him the powers of Captain Atom!
