Superhero Feline Problem Solving Techniques

Catherine, also known as Cat: compassionate, kind, considerate, and completely incapable of valuing the lives of assholes. Among her assets are an encyclopedic knowledge of poisons, a grab bag of sneaky powers, and a complete lack of messing around. She's also wound up in Brockton Bay, much to the (terminal) displeasure of the local villain population.
