Deadpool is back to hijack the recently released Avengers: Endgame trailer. The Merc with a Mouth can't get enough of poking fun at his fellow Marvel pals, and he's stepped up his game quite a bit since he last got into the Infinity War trailer. Marvel Cinematic Universe devotees have been going through every single frame of the new trailer to see if the Russo Brothers have hidden anything that may give a clue of what we'll all be in for next year, but the Merc with a Mouth has other ideas.

The Deadpool version of the Avengers: Endgame trailer begins with Wade Wilson's head on Tony Stark's as he sends his goodbye message to his beloved Wolverine mask. It's pretty funny, even though the guy doing the voice over doesn't do the best job imitating Ryan Reynolds, though his dialogue is pretty spot-on. From there, Deadpool's head is pasted on every single character in the trailer, except for Peggy Carter's face. Instead, she's replaced by Wolverine.

Elsewhere, the Merc with a Mouth makes it pretty obvious that he wants the Avengers to succeed so that they don't make a fifth movie. He calls Thanos the giant purple Homer Simpson and is generally unimpressed with the emotional tones of Avengers: Endgame. To add further insult, when the title is revealed at the very end of the trailer, the Merc with a Mouth covers it up with his arm, which seems exactly like something that he would do in an effort to anger all of the hardcore Marvel fans.

This isn't the first time that Deadpool has gotten involved with Avengers: Endgame. When the trailer first dropped and the title was officially revealed, a fan bought the URL for the movie and had it redirect to the 21st Century Fox site for Once Upon a Deadpool. He offered the URL to Marvel Studios in exchange for tickets to the world premiere, but the studio did not respond. However, Ryan Reynolds did and sent the creative trickster an impressive package of his Aviation Gin, which is worth quite a bit of money. Reynolds was proud of the prank and rewarded the perpetrator.

Once Upon a Deadpool is currently in theaters for another few days, so if you want to see it, get a move on. The PG-13 version of Deadpool 2 will only be in theaters until December 24th, which is this coming Monday. As for Avengers: Endgame, we have to wait a bit longer for that. The highly anticipated sequel hits theaters at the end of April and fans are counting down the days. Thankfully, MCU fans also have Captain Marvel to look forward to in March to get their fix.
