The Atom

Few names carry as much weight in DC's legacy as The Atom, and this Modern Age incarnation stepped onto the stage in style — debuting in the New 52 Free Comic Book Day Special Edition in 2012, courtesy of the powerhouse creative team of Geoff Johns, Ivan Reis, and Joe Prado. Rubbing shoulders with titans like Superman, Wonder Woman, Green Lantern, The Flash, and The Question across titles including Justice League and Adventures of Superman, this version of The Atom has kept genuinely elite company throughout a publishing run stretching into 2025. With a relatively focused but prestigious footprint in the catalog, this is a character whose appearances carry real significance — quality over quantity, in the best collector tradition.
