Comic overview

Ray Palmer discovered fragments of a white dwarf star. He fashioned the pieces into lenses and discovered that they could shrink matter. However, the matter only remained stable for an hour before exploding. While taking some children on a hiking trip, a cave-in trapped them all underground. Ray was forced to turn the radiation from the lenses on himself to shrink down small enough to find and opening and save them. He discovered that something about his own biology kept the white dwarf material stable.

Ray Palmer fashioned the white-dwarf lenses into a belt. He created a blue and red costume for himself and became the Atom for the first time.
