Doll Man (Darrel Dane) is a Quality Comics (and later DC Comics) superhero created by Will Eisner. He could shrink to six inches while retaining normal strength. He was probably the first example of a shrinking superhero. His girlfriend, Martha Roberts, later became Doll Girl.
After DC Comics bought Quality's superhero characters, Doll Man was made a member of the Freedom Fighters and, after the Crisis on Infinite Earths, was retconned into having been a member of the All-Star Squadron.
Another Doll Man appeared in a film, with a comic adaption by Malibu Comics. He was a doll-sized alien, chasing a similarly-sized criminal.
A modern version of the DC Doll Man and Doll Girl have briefly appeared in Teen Titans, although little is learnt about them.
Also in the DC Universe, the most recent Doll Man is a non-powered criminal who has encountered the current Batgirl.
