The Merc with a Mouth is back! Deadpool 2 is set for release on May 18. Ryan Reynolds returns as everyone’s favorite mutant, and he’s bringing some new friends along. Fox has been tight-lipped regarding the new characters in Deadpool 2, but the film’s final trailer revealed the identities of a few X-Men characters and other newcomers.

During the first film’s post credit scene, Deadpool broke the fourth wall and told audiences that Cable would be in the sequel. Comic book fans were thrilled about Cable and even more excited when Fox cast Josh Brolin in the role. In addition to Cable, Deadpool 2 will introduce the origins of the fan-favorite Marvel superhero team X-Force.

Not familiar with the comic books? That’s why we’re here, to tell you everything you need to know about the new faces in Deadpool 2.

Cable

Cable’s real name is Nathan Summers. He’s the son of Scott Summers (aka Cyclops) Madelyne Pryor, a clone of Jean Grey. Nathan first appeared in 1986 in Uncanny X-Men #201, as a newborn. He reappeared as an adult in 1990’s The New Mutants #87. When he was an infant, Cable was sent into the future, where he learned to fight, gained cybernetic enhancements, and became the leader of the New Mutants. Cable is an extremely serious character, who often travels to the past to prevent potential cataclysms.

Eventually he joined forces with Deadpool in the series Deadpool & Cable, which was basically the superhero equivalent of The Odd Couple. Cable’s frankness and stoicism mixed perfectly with Deadpool’s patented brand of hilarious insanity. In each issue, they were just as likely to fight each other as they were to team up.

Cable is the antagonist In Deadpool 2, but he seems to be following his M.O. from the comics. From what we’ve seen in the trailers, Cable will be hunting down a mutant child named Russell. His reasoning hasn’t been revealed yet, but we can assume that it’s to prevent a possible tragedy in the future. Deadpool has taken it upon himself to save the kid, but he’ll have his hands full. Luckily, ol’ Deadpool has assembled a team to help him in his fight.

Domino

Domino’s real name is Neena Thurman and she was first introduced in 1992 in X-Force #8. Her power controls luck. While that might sound like a passive mutant power, it makes her extremely dangerous in a fight; things just go her way, no matter how unlikely the chances seem to be. Domino is also an expert marksman and very skilled in hand-to-hand combat. She has a torrid history with Deadpool; throughout the comics she’s been his partner, love interest and X-Force teammate.

Zazie Beetz plays Domino in Deadpool 2, and based on the final trailer she is fairly similar to her comic book counterpart. Deadpool recruits Domino to his team, nd this appears to be the first time the two have met. The first film established a love interest for Deadpool, Domino will likely serve as his teammate and partner in the sequel.

Bedlam

Bedlam, aka Jesse Aaronson, is a mutant who first appeared in 1995 in X-Factor #1. He originally possessed the ability to create an electromagnetic field that could disable any nearby technology. His powers evolved, so that he could affect the neural chemistry of the brain. This allowed him to project feelings of pain and confusion into other people at will. He is also a long-standing member of X-Force. Terry Crews plays Bedlam in Deadpool 2, and he’s a welcome addition to the team.

Shatterstar

Lewis Tan’s Shatterstar is an obscure X-Men character to most viewers, but he’s come in and out of prominence over the years. He’s even been the leader of X-Force. His real name is Gaveedra-Seven; much like Deadpool, he’s a genetically engineered human. Hs powers are mutations, but the result of experiments. He first appeared in 1991 in The New Mutants #99, and possesses superhuman strength, a healing factor, and enhanced cognitive function. Shatterstar also wields dual swords that can generate teleportation portals. Like Cable, Shatterstar is from the future, but he’s also from an alternate dimension. We’re dying to know where he got that awesome helmet!

Russell

Deadpool 2’s production team has been secretive about the young mutant Russell. Cable appears to be hunting him, but we don’t know why. We know thatJulian Dennison plays Russell and that he has pyrokinetic powers – he can create and manipulate fire on a massive scale. In the final trailer, we see Deadpool and Russell in the same mutant prison. It’s possible that he could be a young version of Russell “Rusty” Collins from comics. Rusty has the same abilities as Russell in Deadpool 2 and was also imprisoned on several occasions.

Peter

The newest and most unlikely member of Deadpool’s team is Peter, played by comedian Rob Delaney. Per the trailer, he has no mutant abilities. He seems nice! Peter may be more of a walking punchline than a helpful team member, but with Deadpool you never know. For now, Peter’s only known powers are growing a handsome mustache and wearing sensible khakis.
