Robinson Goode is a figure whose past is surrounded in mystery. She currently serves as an enforcer for the "Invisible Mafia", a clandestine criminal organization based out of Metropolis. She also works as a reporter for the Daily Planet, although this is just to ensure the secretive nature of her organization is upheld.
Robinson possesses the metahuman gene, providing her with the power to convert her whole body into a red mist. The mist is toxic to other people, including Kryptonians like Superman, making her a very dangerous foe for the Man of Steel.
