Mara is just like her brothers; a hunter. She knows everything there really is to know about supernatural beings. She also knows how to stay calm and cool in dangerous situations and (usually) knows exactly what to do. Like Dean, Mara is also a foodie and will eat pretty much anything (though, unlike her brother, she'd rather have cake than pie.) Like Sam, Mara has seen her fair share of traumatic things. But she doesn't let that stop her from the job at hand.
