Catherine Davis is a mutant with only one useful power. Flight. Her other “powers” including having cat ears and a tail, which aren’t much useful outside a comic book convention.
As a winged catgirl, Catherine has had difficulty finding a traditional job, or even proper education. So she’s made the most of it and registered as a hero in Paragon City, relying on her appearance to qualify, and her basic firearms and martial arts training to actually get the job done.
Being a professional superhero doesn’t pay well, but the benefits package can’t be beat.
