I wanted to see who everyone thought did the best job at being the "bad guy" in the show, and I was going to put it all in one poll, but then I Wikipedia'd it, and found out that there is quite a bit more evil guys in there than I had originally suspected, so it has been turned into two separate polls.
I left out Cherrymon and Datamon because they wouldn't fit, but I hope that doesn't affect anyone's choice...
