Elphaba (Wicked by Gregory Maguire)Read about another entry on the list.
Sure, the movie version’s Wicked Witch of the West was cool, but she doesn’t hold a candle to Wicked’s version. While not technically a villain, Elphaba was still feared throughout Oz, and for good reason. A powerful sorceress and a rebel fighting against the tyranny of the Wizard, Elphaba had no problem with upsetting authority, and was willing to kill if she needed to. (I’m beginning to see a pattern: “bad witch”= “pretty casual about killing people.”)
