Joan Paul is a mutant with the ability to shrink down to very very small sizes. Since the age of fifteen she has made a living as a specialized cat-burgler. Her weapons and martial arts skills are more for show and desparation than for any desire to fight superheroes. She works for the Dynasty as the Rat as the previous Rat, a mentalist of moderate power, died in combat with The Pacific Lords, a large hero team based around the pacific rim. She enjoys the pay and the chance to spy and grab loot, and she really appreciates all the superhuman back up she has if things go wrong. Unable to see past her own being; Joan feels that the world owes her comfort and happiness. She takes what she wants and never consideres what others think unless they try to stop her, then they are oppresors of life and liberty. Vain about her abilities and appearance, even in the face of superior specimens and greedy to the extreme, she is also something of a coward. Her time with the Dynasty has made her "enjoy" combat, particularly when they have numerical superiority; but if she experiences too much resistance, she might panic and run. "Guess you didn't notice me." Make yourself small and attack from surprise. Repeat. The Rat's combat powers aren't out of line in any superhero campaign. If she's not tough enough, get her some more defenses and maybe some damage classes with martial arts and a few more weapons A slim, attractive woman who accentuates what she has with tailored clothing and outlandish, but tasteful makeup. She wears purple all the time. Her costume is white with purple boots, gloves, and trim. She wears no mask; maintaining her secret ID by staying shrunk.
