This is a video by the same guy who made the one on the top 10 giant movie monsters. That's his list of the most badass guys in movies.
I find the clip hilarious, but, apart from that: do you see any general pattern? What is this guy seeing in those villains to make them the "most badass"? Does it tell us something about the author, and/or about what is generally perceived to be the characteristics of a "badass"?
Warning!!!!!!!!!: most of the scenes are rather harmless, but you do have the death of Capt. Rhodes where he is torn apart, alive, by zombies; and a guy shooting someone's hand. If you are sensitive to such things, skip it.
