Inspired by the NCAA basketball tournament, Half Price Books has launched a Tournament of Villains, pitting 64 evil characters against one another to figure out “who’s the baddest one of all.”

The voting period for round one ends today at 2 p.m. CST. These antagonists come from a diverse range of titles; from William Shakespeare‘s Iago (the play Othello) to Ken Kesey‘s Nurse Ratched (the novel One Flew Over the Cuckoo’s Nest) to J.K. Rowling‘s Lord Voldemort (the Harry Potter series).

Here’s more from the website: “All epic stories have the same things in common: Confrontation. Tension. Obstacles. A proper antagonist propels the story, raises the stakes, and does everything in his, her or its power to win each battle. We thought we’d give these scoundrels a bonus round, sans any do-gooders to get in their way – a proper second chance to prove once and for all who’s the baddest one of all.”

Last summer, Voldemort only survived three rounds in MTV’s “Harry Potter World Cup.” Do you think the sinister Tom Riddle will do better in this time?
