Superheroine inspired by Hera, the Greek goddess, envisioned as a ruler of interstellar alliances in a futuristic setting. She wears an outfit that combines Greek regality with advanced star-tech designs, featuring crown motifs. Her attire includes a blend of sovereign sapphire, alliance amethyst, and monarch gold colors. She holds a scepter symbolizing her power to seal and enforce cosmic pacts. The image should capture her as a majestic figure, embodying the unity and leadership of the vast cosmos, standing in a commanding pose, full body.
