The old and new Huntresses do battle in the Levitz, Staton and Layton Justice Society story in All-Star Comics 73 (July/Aug 78).
Picking up from the end of the last story, Wildcat lies on death's door at the hospital while the new Huntress fights the old one in the JSA headqaurters, trying to retrieve the freeze gun Icicle had used on Wildcat.
Dr. Fate and Hawkman get together with a mysterious figure in Egypt, as that subplot advances.
When Huntress does not return to the hospital Green Lantern uses his ring to see what is delaying her. Seeing her fighting the other Huntress, he, Flash and Power Girl head to help her. But they wind up getting prevented by the Thorn and Sportsmaster.
The villains do their best to kill Joan Garrick, which is sufficient to keep the heroes from getting to their headquarters. Still, Power Girl takes down Sposrtsmaster and the Flash defeats his old foe the Thorn.
But by that point the new Huntress has defeated her namesake all on her own. She gets the freeze gun and brings it back to the hospital,in time for Wildcat's life to be saved.
Of the villains, Rose and Thorn appears next, in the pages of Infinity, Inc, in 1985. Within a year of that the evil Huntress returns in a cameo in Crisis on Infinite Earths, before showing up again, along with Sportsmaster, in Infinity, Inc. the following year.
