6.) Lilah Morgan (Angel) - Joss Whedon has so perfectly mastered creating worthy enemies that is was far too hard to limit this list to just one of his creations. The underappreciated Lilah (Stephanie Romanov) was a lawyer for Wolfram & Hart, the corporate-gone-evil law firm. As a part of her work at the firm, Lilah did her share of plotting to kill Angel, but it was her gameness and twisted humor that made her a great Joss Whedon bad guy, or in this case, girl. Perhaps no moment better exemplified that than when she dressed as up as the object of Wesley's affections, the geeky Fred, by donning a school girl outfit and glasses.
