The gravity brassier is a scale bodice that was originally worn by Madame Murel. She was dispatched before she could use it. Soon after, it was acquired by Mobster Kingpin who used it to become Dark Matter Mobster Kingpin, and later, Black Hole Mobster Kingpin. Unlike normal bodices, instead of modifying height and vim, mass and volume are modified. So far this has only been used to increase mass for defensive purposes.
