Update: The Deadpool 2 writers want Peter to get his own X-Force spinoff.

Deadpool 2 star Ryan Reynolds shared a picture of a fan showing off their awesome Peter cosplay. In addition to bringing back Deadpool and other favorites from the original film, the upcoming superhero sequel Deadpool 2 introduces a bunch of new characters to the franchise, many of them fan favorites from the comics. Foremost among these of course is the mutant Cable, played by Josh Brolin.

Along with a new adversary, Deadpool also gets support from his own Avengers-like team, the X-Force. Zazie Beetz plays X-Force member Domino, Bill Skarsgård plays Zeitgeist, Terry Crews plays Bedlam and Lewis Tan plays Shatterstar. And then there's the other member of the X-Force, a guy with no apparent superpowers named Peter, played by Rob Delaney. Peter made his hilarious debut in the final Deadpool 2 trailer, and since then he's become another unlikely fan favorite.

As part of the Deadpool 2 marketing push, Peter was even given his own very amusing Twitter account mixing typical dad tweets with teases from the film. Apparently, the Peter hype is working because now there are even Peter cosplayers. Ryan Reynolds himself recently ran into a fan cosplaying as Peter and couldn't resist posting an image. See the shot below:

In the film, Deadpool finds himself a little in over his head dealing with Cable and puts in a call for superhero applicants. In addition to meeting the usual mutants with special abilities, Deadpool also meets with Peter, who's just a guy looking for a job. For some reason, Deadpool decides to hire him. The next thing we know, Peter is skydiving into danger like Tom Cruise with a bushy dad mustache.

The Peter character is another example of the wry, form-breaking humor we've come to expect from Deadpool. But will Peter prove to be more than just a gag character? It wouldn't be surprising to see Peter actually end up playing a significant role in the film. Writers Rhett Reese, Paul Wernick and Reynolds already proved in the first Deadpool that they're willing to play around with the conventions of the superhero genre. The whole point of Deadpool is to subvert comic book tropes, while simultaneously delivering legitimate action.

And even if Peter does end up as a gag character in Deadpool 2, the gag has already paid off in terms of social media buzz and fan excitement. Of course, the potential downside of the Peter buzz is that, should something bad happen to him in the movie, there will be a huge backlash. Just remember what happened when Stranger Things killed off Barb. Let's hope we don't end up enduring a #JusticeforPeter campaign after the film releases.
