One of my favorite evil masterminds on TV right now is a grandma. On Heroes, Angela Petrelli and her granddaughter Claire don't exactly have a warm and fuzzy relationship, but then again, "warm and fuzzy" is not Angela's M.O. Especially this season, she has a powerful ability to switch from conniving and cruel to soothing and protective. Then again, if she's acting all nurturing, you can bet there are some ulterior motives involved. I love this badass grandma.
