Thanks to everyone who voted! A lot of good suggestions didn't make the cut. At the last minute, I replaced Number 6 from The Prisoner with Godzilla. I think Number 6 would be cantankerous and fun in DotF, but I just felt that the tourney needed a little more diversity. Nothing says diversity like a daikaiju.
Also, for those who were paying attention, you'll notice I made one other last-minute switch, replacing William the Black (from Spherical Tomi) with Tomi herself at the number 1 seed.
