I’m imagining a matriarchal fantasy nation where the queens have always been the country’s protectors. Maybe just because that’s how it is, but maybe because of a mystical potion or ritual passed down from mother to daughter or something the women on the royal family grow into massive, hulking musclebound beasts during puberty. They can demolish fortresses with their bare hands, and their muscles are so dense and hard that swords just break against their bodies. Traditionally the queen is always naked, to show her muscles and strength, because of how hard it would be to make fitting clothes, and because nobody can actually hurt her anyway.
