Who is the most powerful slasher that The Dude could survive? (The Big Lebowski)

Jeffrey "The Dude" Lebowski has found himself in a bit of a pickle. He's caught the attention of a slasher movie villain. What would be the most dangerous slasher movie that the Dude could survive?

Let's say that the Dude knows something is up, and he consults with Walter and Donny on the issue. The slasher is after him for whatever their normal reasons would be. IE the Dude has a piece of the Leprechaun's gold, the Dude is the object of Michael Myer's obsession, the Dude is camping at Camp Crystal Lake, etc. The villain doesn't have to be permanently defeated or anything, The Dude just has to abide.
