Aurora, the astronaut member of the Cy Girls, which were 1/6-scale female action figures released in the late 1990s/early 2000s. For want of a better term, I always referred to them as "Action Barbies."
Yeah, Aurora's head sculpt is a little weak, especially by today's standards, but I absolutely love the retro space costume and accessories. And the body joints remain quite stiff, so she'll hold just about any pose I put her in.
