February's Deadpool was a complete game-changer in the very hot world of comic books being portrayed on the silver screen. As an off-shoot of theX-Men film series, it set records as the highest-grossing film of theX-Men franchise and the highest-grossing film ever to receive an R-rating.While summer blockbusters based onMarvel Comics such as Captain America: Civil War andX-Men: Apocalypse are designed for a fairly broad, family-friendly audience,Deadpool(and the anticipatedDeadpool 2, which is almost certain to feature Ryan Reynolds battling someone portraying Marvel's villainous Cable)is designed specifically for a more "mature" audience.

Next on-screen nemesis.

As the post-credits of Deadpoolclued viewers into the idea of Cable as Deadpool's next on-screen nemesis, they also offered some suggestions for who could play the "big guy with a flat-top," including such iconic actors as Dolph Lundgren, Mel Gibson... and Keira Knightley. Ron Perlman expressed interest in the role, with acting experience that includes the titular character in the Dark Horse Comics-basedHellboy movies and the racist Reinhardt in the Marvel Comics-basedBlade II.

Suggesting the role of Lady Deadpool, Bella Thorne has even expressed interest in playing a part in theDeadpool franchise.

But thanks to a recent Twitter conversation, members of the WWE Universewho have been following Vince McMahon's brand since the Attitude Era of the late 90s are hoping to see Adam Copeland — better known to the rest of the world as former WWE Champion Edge — as the time-travelling Marvel bad-guy up against the anti-hero Deadpool in the film's highly-anticipated sequel.

'Edge' as a WWE Superstar.

For die-hard fans of Marvel Comics that aren't familiar with the goings-on of World Wrestling Entertainment, Adam Copeland is still referred to simply as "Edge" on WWE programming.

Edge debuted on WWE programming in 1998, as the Attitude Era was reaching its peak with superstars like "Stone Cold" Steve Austin, The Rock and Degeneration-X. He wrestled for WWE until an injury forced him to retire from in-ring action in 2011. Among many other accolades, Edge was an 11-time world champion, 14-time tag team champion, and a 2012 Hall of Fame Inductee.

Since leaving in-ring action, Edge has stayed active within WWE, most recently as the co-star ofThe Edge and Christian ShowThat Totally Reeks of Awesomeness on the WWE Network.

Adam Copeland as an actor

Forced to leave in-ring competition, Adam Copeland found work as an actor.

Before beginning his show on the WWE Network with long-time friend and tag team partner Christian Cage, he was Dwight Hendrickson on Haven for four seasons. Last year, he played DC Comics character Albert Rothstein/Atom Smasher on an episode ofThe Flash, proving he has the ability to convincingly portray a super-villain.

Latest updates onDeadpool 2

There is still plenty of time for Marvel Entertainment and 20th Century Fox to figure out who they want to star oppositeRyan Reynolds in theDeadpoolsequel. Edge's size would be a new look for the traditionally jacked-up super-villain, but Marvel has been rethinking a lot of their characters, including a female Wolverine in Marvel Comics.

Keira Knightley might seem like a stretch, but Marvel re-imagined lawyer Jeryn Hogarth as Jeri (Carrie-Anne Moss) inDaredevil, so anything is possible.

Sequel.

Few details have been released aboutDeadpool 2. It was confirmed in April that the sequel is already in development, with filming expected to begin in the Fall. Aside from the inclusion of Cage, director Tim Miller and producer Simon Kinberg have talked about aSpider-Man crossover. However, with Spider-Man's inclusion in the Marvel Cinematic Universe forCaptain America: Civil War, that Marvel match-up may never come to fruition on the silver screen.

FollowingX-Men: Apocalypse, the next film in the series is expected to be anotherWolverine film, which could very possibly include a cameo from Ryan Reynolds as Deadpool.
