Kari will kick your ass if you look at her wrong. Her capacity for violence knows no boundaries. She is quick to anger and quick to kill! She has spent her whole life training in the deadly martial arts of far-off places whose names are not important.... Her one weakness is her invisible hat. It was placed upon her head by the a secret government agency. As long as she wears the invisible hat, her powers of raging violence are contained and she will seem, for all intents and purposes, like a very nice lady. the trick here is that she doesn't know she's wearing the hat (because it's invisible... duh!) so don't let her know and do your best not to knock the invisible hat off of her head or we are all dead.
