Been looking for this story for a long time now, the complete version was posted several yrs back on one of the GTS forums.  Was able to assemble (most) of the storyline from two sites, one the New GTS Shrine, the other a Spanish website about Flash Gordon that had a large collection of the Dan Berry run with the comic strip from 1983-84.

Even so, there's some holes here in the continuity, but I think its enough to follow the plot of Flash's adventure with Julah the Golan. 

1983 Storyline









1984 Storyline

 









What follows after, and is missing here, is Julah’s return to a normal stature and existance.  Flash Gordon a few years later had a second encounter with Julah, a less favorable one – the life she expected as a normal was not the one she had hoped for and was once again transformed into a Giantess by the priest of Saban.

I would have included the later encounter w/Julah, if I had found that sequence of the sequel story line.  All I came across were two panels at the New GTS Shrine.  As I best recall, in her second incarnation as a GTS she was cool and aloof in her dealings with Flash, almost as if she'd undergone a personality change, becoming the Giantess Goddess in mind as much as in body.

Even so, she eventually helped him to escape the Saban a second time.

When I get the time, maybe I'll post what I have of a story line from last years Ink Pen* strip by Phil Dunlap - where mere mortal Jenn Erica gets superpowers as The Empoweress.

*(If unfamiliar w/ it, think of as Bloom County for the pop-culture of Superheroes/heroines)

Interesting and provocative story for it's time... It looks as if there were a few different colorists doing the different panels as evidenced by the changing hair color of Julah.
