The R-rated superhero adaptation Deadpool is a bona fide box office blockbuster, taking in $285.6 million domestically and $324.1 million internationally for a global total of $609.8 million worldwide. The movie not only gave fans the foul-mouthed Merc With the Mouth they've been waiting for, but also introduced us to a new X-Men mutant, Brianna Hildebrand's Negasonic Teenage Warhead. As it turns out, this character almost looked much differently on the big screen, with concept artist Joshua James Shaw sharing his early concept artwork for this mutant.

Fans have speculated that, based on her costume, Negasonic Teenage Warhead may be appearing in 20th Century Fox's X-Men spinoff The New Mutants, which is currently in development. While that hasn't been confirmed, it's likely that the actress will return to reprise her role in Deadpool 2, which was recently given the green light by the studio. The entire creative team and the cast are expected to come back for this sequel, but nothing has been made official quite yet.

After receiving a slew of positive reviews, Deadpools $135 million opening weekend shattered the record for highest grossing R-rated opening weekend of $91.7 million, held for 13 years by The Matrix Reloaded. It also broke Fifty Shades of Grey's February record of $85.1 million, along with its four-day President's Day weekend record ($93 million), the record for highest-grossing R-rated comic book adaptation (300, $70.8 million), largest winter opening weekend (American Sniper, $89.2 million) and it became the biggest opening ever for 20th Century Fox, surpassing 2005's Star Wars: Episode III - Revenge of the Sith record of $108.4 million.

We reported earlier today that Deadpool is now the highest-grossing X-Men movie of all time, after just 10 days in theaters. The movie was produced on just a $58 million budget, which is quite low for your average superhero movie. It's also worth noting that, last month, early projections predicted the highly-anticipated Batman v Superman: Dawn of Justice will earn $154 million on its opening weekend, and that's with a PG-13 rating and two of the most beloved heroes on the planet featured in the same movie. Obviously, those numbers could, and most likely will, change, especially since Deadpool's early projections put it between $55 million and $60 million. Still, for Deadpool to earn so much with the restrictive R rating, opening higher than all of the other X-Men movies, it could provide a wake-up call to studios that may lead to more R-rated fare.

It was recently confirmed that original Deadpool writers Rhett Reese and Paul Wernick are coming back to write Deadpool 2. While the studio hasn't officially confirmed the sequel yet, or a release date, Ryan Reynolds appeared in an end credits sequence where he confirmed that the iconic comic book character Cable will show up in the sequel. Ryan Reynolds will most certainly return as the Merc With the Mouth for the sequel, but it isn't known if any of the supporting cast will return. The cast also includes Morena Baccarin, Gina Carano, Ed Skrein, T.J. Miller, Brianna Hildebrand, Olesia Shewchuk, Style Dayne, Rachel Sheen and Dan Zachary. Take a look at this artwork below, and stay tuned for more on Deadpool and Deadpool 2.
