While we may not know the fate of everybody in the Marvel Cinematic Universe following the events of Avengers: Infinity War, it does appear that Deadpool survived, as a fan who has been making a habit of inserting Deadpool into Avengers trailers has now given the same treatment to the latest Avengers: Endgame trailer, and the result is actually pretty entertaining. Check it out.
The Deadpool-filled trailer gives us all of the video that we got with the new Avengers: Endgame trailer, but replaces all of the audio with commentary by Deadpool, or at least a reasonable facsimile provided by the Mightyraccoon! YouTube channel. If you've seen any of the previous trailers the channel did that added Deadpool, you'll know what you're seeing here. We get a combination of Deadpool making sardonic comments to the Avengers as well as becoming several of them at various points in the trailer.
There are a couple of rock solid highlights, which come when Deadpool actually becomes part of the trailer, in the flashback shot from Captain America: The First Avenger, Deadpool actually lifts the pre-super soldier Steve Rogers so that he can better see himself as a soldier, which is great, and a nice bit of video manipulation. Then, at the end, Deadpool gets clocked in the back of the head by Stormbreaker. It's a simple gag, but an effective one.
It's actually sort of nice to get this shot of humor in the Avengers: Endgame trailer. The Marvel movies usually have a good sense of humor to them, but the dour and desperate circumstances surrounding the new movie means that everybody is very serious and nobody is cracking a smile. There's probably some humor in the film, but showing it off in the trailers would almost certainly shift the tone quite radically.
Of course, with the expectation that the Disney/Fox merger will be officially complete as of later this week, one can't help but wonder if something like what we see here is actually in our future. The Deadpool movies are one of the few parts of the Fox/Marvel universe that are hits and likely to survive the merger without being rebooted. Does that mean we could see Deadpool along side the Avengers in a future movie? It seems like a long shot, but at this point pretty much anything is possible.
With this likely being the last trailer we will see before Avengers: Endgame hits theaters, it could be our last Deadpool-infused trailer. We have no idea at this point if there will ever even be another Avengers movie, or what characters it will include if we do see it. We're not sure what MCU movies we'll get after Spider-Man: Far From Home. While we now know that Guardians of the Galaxy Vol. 3 will happen, it's going to come much later than originally planned.
