Dude, this is kinda a hard one. I love Pirates of the Caribbean. Although I'll say an unpopular opinion here: I love Will Turner more than Jack Sparrow. Like Jack is fantastic and awesome and amazing and Johnny Depp is hot shit, but I loved how Will's character changed throughout the movies.

But then Stevie is a ninja and the Winchesters can be ninjas sometimes. Hell, Sam said "Well then we'll just ninja past them" in the finale like it was no big deal. Hanson once said that they want a Midget Ninja Pastry Chef as well.

So I'm gonna go with ninjas.
