She-Ra vs King Hsss. I don't think I've seen pictures of King Hsss and She-Ra together yet. In fact, I don't think She-Ra and King Hsss have ever interacted over the various media portrayals that I can recall.
I think they look quite nice fighting each other. The green on King Hsss contrasts nicely with her white and gold.
