Starman is a name used by several different fictional DC Comics superheroes, most prominently Ted Knight and his sons David and Jack. Created by writer Gardner Fox and artist Jack Burnley, the original Starman, Ted Knight, first appeared in Adventure Comics #61. An astronomer, Knight invented a "gravity rod", later reinvented as a "cosmic rod", allowing him to fly and manipulate energy, and donned a red and green costume with a distinctive finned helmet. Like most Golden Age heroes, Starman fell into obscurity in the 1950s. In the ensuing years, several characters, with varying degrees of relation to the original, briefly took the mantle of Starman. In Zero Hour: Crisis in Time #1, writer James Robinson and artist Tony Harris introduced Jack Knight, the son of the first Starman. A reluctant, non-costumed hero, he inherited his father’s name and mission and used his technology to create a cosmic staff. He starred in a critically acclaimed series, written by Robinson, from 1994 until 2001. The current successor of Starman is Stargirl, formerly the second Star-Spangled Kid. Below, in chronological order of activity, are the characters to have used the name "Starman".
