As a fan of the original Guardians of the Galaxy since their inception, I was bound to take an interest in Starhawk, the enigmatic individual who was folded into their ranks following the Earth's liberation from its conquerors, the Brotherhood of the Badoon. Created by Steve Gerber and Sal Buscema and first appearing in The Defenders, this new character was appropriately given few details (if we can even use that word) to pique our interest. He described himself, for instance, as "the light, and the giver of light"... he has three young children, settled in an Earth-like environment on a dome-covered asteroid... he appears involved with a woman named Aleta, whom he communicates with via a computer console screen and describes in a way that implies more at work than a depth of feeling ("all that I am, all I can be, flows from her," a connection alluded to in Starhawk's later battle with Korvac)... and, perhaps most mysteriously, he often offers information and/or assurances to others on various matters of interest as "One Who Knows," a description which is often taken at face value though never accompanied by explanations regarding what or how.
Initially, we as readers are exposed to Starhawk when he appears on the Badoon homeworld to give aid to Maj. Vance Astro (one of the Guardians) and the Valkyrie (one of the Defenders) who have been transported there mistakenly. Yet once Starhawk has healed the Valkyrie of her injury suffered in this world's swamps on arrival, she and Astro find no sign of Earth's conquerors; instead, they discover their female progenitors, living separately in peace in an advanced civilization where they remain ignorant of the Brotherhood's activities of conquest throughout the galaxy.
Eventually, the Defenders are reunited, and set about their task of freeing the Earth from Badoon tyranny. But once Strange has mystically set free all of the imprisoned humans worldwide, Starhawk plays a crucial role in the Defenders cutting their mission short and returning to their own time period.
The "story for another time" that the narrative speaks of arrives a few months later in early 1976, where Gerber and artist Al Milgrom launch the Guardians in their own series of stories in Marvel Presents which, among other things, serve to further explore the character of Starhawk. In fact, we'd do well to keep in mind Maj. Astro's words* in that last panel, as they'll come to mean more than he and ourselves are, at present, aware of.
