Doll Girl was the girlfriend and crime fighting partner of Doll Man (Darrel Dane).
Martha Roberts was the daughter of Professor Roberts, who tutored his young protege Darrel Dane in his home laboratory. During the summer of 1939, Martha was being blackmailed by a criminal named Falco over love letters she had written one of her former college teachers. After imbibing a concoction, Dane found himself shrunk to the height of six inches, but with his normal strength multiplied by twenty. Martha sewed him new clothes to wear, and he began to worry that he might never be able to regain his normal height. After refusing to pay Falco any more blackmail money, Martha was kidnapped by Falco and rescued by the "Doll Man". Finding through intense concentration, Dane could affect his height, he decided to begin to fight crime as Doll Man, often assisted by Martha (who also became his scientific research assistant).
Martha accompanied Doll Man on at least one of his earliest adventures.
There was at least one period of time in the 1940s during which Martha Roberts no longer knew the secret identity of Doll Man.
In 1944, while wishing and concentrating about being able to shrink down to aid Doll Man, Darrel also was thinking about the same thing and suddenly, Martha's height and weight dwindled down until she was on the same scale as Doll Man. She briefly teamed with Doll Man as Midge. In 1951, Martha adopted a longer-lasting super-identity as Doll Girl.
