10 Reasons Supernatural's Rowena Is the Baddest Witch in Town

No challenge is too big for this witch. When Winchester and Co. were clueless as of how to defeat Amara, Sam suggests that they get help from Rowena. Okay, so technically Rowena unleashes the Darkness upon Earth. But when push comes to shove, she isn't afraid of a challenge, even if it means facing an almighty deity. While not powerful enough to defeat God's sister, Rowena still briefly brings Amara to her knees with some extra mojo from her witch friends. Not even scrappy Dean Winchester or calculating Crowley could put a dent in Amara.
