Until Walt (Bryan Cranston) hit the scene, science teachers had no chance at winning the bad ass prize. However, you apply those chemistry skills in a seedy RV-turned-meth lab and those days are over. He'll do anything (blowing up a dealer's hangout is just one example) to protect his family -- and his turf.

We'll call Skyler (Anna Gunn) the "Quiet Bad ass," because while she might not be out in the desert cooking chemical compounds, she has to deal with arguably the biggest problem of all: Her husband, Walt. As for laying down the law? Skyler's the only one Walt halfway listens to.
