Salu Digby, alias Atom Girl existence was nothing but myth to the second wave of Legion of Super-Heroes.

Her very existence was in doubt until Brainiac 5 enlisted her aid to stop Elysion of Terror Firma from destroying the United Planets' headquarters on Earth.

She claims to have been exploring Brainy's microverse and simply lost track of time. When Invisible Kid had used "the Shrinking Violet" as excuse when confronted for his betrayal to Cosmic Boy, Invisible Kid and Atom Girl agreed to continue the ruse, as she prefers her presence on the team a mystery.

Later, on a mission on Lallor, she battled E.R.G.-1 with Shadow Lass and Timber Wolf. Atom Girl convinced E.R.G.-1 to redeem himself, as it was revealed that he had been manipulated. Atom Girl has expressed interest in dating him.


  • Size Alteration: As a native of the planet Imsk, Salu Digby possesses the ability to shrink from normal human size to sub-atomic sizes, and any size in between. She retains most of her physical strength even at smaller sizes.


  • Hand-to-Hand Combat (Advanced): Salu is a skilled hand-to-hand combatant using special styles of unarmed combat depending on her size. If she is small, she takes advantage of the opponent's larger form by assaulting points on their body that they would not expect and move to another before they detected her.
  • Espionage: Salu's ability to alter her physical size makes her an ideal spy.
  • Firearms: Salu is a skilled gunfighter and marksman.


  • She appears to have a complex about showing herself small in the eyes of others.
