Atom

The living embodiment of "Size doesn't matter," the Atom unleashes all the power of his namesake against evil.

In the 1940s, many people were driven to become heroes and crime-fighters. After years of dealing with bullies, Al Pratt trained to become a fighter and protected others from bullies by donning the mask and cape of the Atom. After retiring from his heroic life, he embarked on a career in physics.

Ray Palmer, research scientist, created a “white dwarf lens” that gave him control over his own mass and size. As the Atom, he fought many villains and strange menaces across time and space, not only alone but also as a member of the Justice League. For a brief time, Ray Palmer went undercover and a man named Adam Cray stood in as the Atom.

Born and raised in Hong Kong, Lun “Ryan” Choi studied under Ray Palmer at Ivy University. After a year, Ryan was told a life-changing secret: Ray Palmer was the superhero known as the Atom. For the next couple of years, Ryan aided the Atom’s activities. When Palmer vanished one day, he left behind a spare size-changing belt with its own dwarf star lens for Ryan to use. As the new Atom, Ryan fights to protect people just as his mentor did and serves as a member of the Justice League of America.
