The Atom

Ryan Choi, a brilliant young physicist from Hong Kong, arrived at Ivy University as protégé to the missing Ray Palmer and inherited the size-changing technology that made him the new Atom. Stepping into Palmer's oversized legacy with his own sharp intellect, Choi embraced the mantle of Earth's smallest — and most scientifically daring — hero.

Born into the turbulent Modern Age with a 2006 debut crafted by the creative team of Justin Gray, Jimmy Palmiotti, and Dan Jurgens, this incarnation of The Atom stepped onto the scene during one of DC's most seismic storytelling periods — the Crisis Aftermath era. Over nearly two decades of publication, this Atom has kept genuinely elite company, sharing pages with the likes of Batman, Bruce Wayne, Green Lantern, The Flash, and Ryan Choi across landmark titles including Detective Comics, Countdown to Final Crisis, and Batman: The Brave and the Bold. With two collector-recognized key issues among their 38 catalogued appearances, this is a character whose Modern Age footprint is modest but meaningful — the kind of figure that rewards the dedicated reader digging deeper into DC's rich, interconnected universe.
