Audrey Page : Golden Guardian (Patreon)

So, the basic concept of Golden Girl as /co/ worked it out was that a plucky teen sidekick gets the Most Common Superpower associated with adult female capes extra hard before the rest of her catches up. But eventually, just as Robin became Nightwing, Audrey grows up, the rest of her fills out, and approximately ten years, a growth spurt that's upwards rather than outwards, and 30 pounts of muscle later she rebrands herself as the Golden Guardian.
