Could be considered a sequel to 'Masters of the Universe'.
I've always liked to think of Galaxis as being a sequel to the live action Masters of the Universe movie, as it could be regarded as being an unofficial She-Ra film.
In the Masters mythology, She-Ra was He-Man's sister, secretly sent away to another planet as a child, who grows up to become a warrior, protecting her adopted home from the villainous Hordak.
In Galaxis, Brigitte Nielsen plays alien soldier Ladera, sister of her planet's ruler (Craig Fairbrass). When warlord/sorcerer Kyla (Richard Moll) kills her brother and teleports to Earth in search of an immensely powerful artifact, Ladera pursues him, and the resulting battles between the two of them in present-day America are similar to those seen in the Masters movie.
It's easy to imagine Ladera and Kyla as stand-ins for She-Ra and Hordak.
