In the comic books, Albert Rothstein is the godson of the original Atom, Al Pratt and grandson of a reluctant supervillain known as Cyclotron. Because of his grandfather's legacy, Albert gained the powers of growth, increased strength, stamina, speed, and durability. During one of his first adventures, Albert learned he also had the power to alter his density to either become intangible and phase through objects or to increase his density, which boosted his already superhuman strength and durability (this power was later ignored or forgotten by writers following Albert's run as a founding member of "Infinity, Inc."). At first, Albert used the name Nuklon and was a member of teams like Infinity, Inc, the Justice League, and eventually the Justice Society.
In the comic books he had a relationship with fellow Leaguer Fire and acted as an older brother figure to Stargirl while Stargirl has (or at least had) some romantic feelings for Atom-Smasher. Albert is also a somewhat controversial superhero in the comic books due to the many times he has killed.
