Deadpool did it again, and this time, he brought some friends. With the release ofDeadpool 2, Marvel's Merc With a Mouth has charmed his way into audiences hearts and earned mostly positive reviews from critics with another foul-mouthed, hyper-violent blockbuster. In this David Leitch-directed follow-up to 2016'sDeadpool, Ryan Reynolds' mutant mercenary teamed up with some new X-Men, encountered a few surprise villains and formed X-Force, one of Marvel's most famous mutant teams. While Josh Brolin's Cable and Zazie Beatz's Domino brought some fan-favorite mutants to the big screen for the first time,Deadpool 2also had room for a lot of Marvel's less famous mutants.

Even by superhero movie standards,Deadpool 2was stuffed with a dizzying number of deep cut cameos and outrageous guest appearances. Now, CBR is taking a look atDeadpool 2's biggest, quickest and most surprising cameos. In this list, we'll be taking a look at some of the movie's nods to Wade Wilson's comic book and cinematic history. We'll also be unraveling some of the blink-and-miss-it celebrity cameos that you might've missed. Finally, we'll look at how these characters tie back into the wider world of the Marvel Universe' X-Men stories and the last 18 years of Fox's X-Men movies.

SPOILER WARNING: The following list contains comprehensive spoilers forDeadpool 2,in theaters now.

18 SHATTERSTAR

Although Lewis Tan's Shatterstar was only on X-Force for about 10 minutes inDeadpool 2, Shatterstar is one of X-Force's stalwart members in the Marvel Universe. The alien warrior was created by Rob Liefeld and Fabian Nicieza in 1991'sNew Mutants#99, just one issue after Deadpool's first appearance. Like his cinematic counterpart, Shatterstar is a sword-wielding warrior from an extra-dimensional planet called Mojoworld. From his impressive ponytail to his double-bladed swords and all-white battle armor, Tan's Shatterstar is a remarkably faithful cinematic translation of Liefeld's first costume for the character.

While Tan's Shatterstar met an untimely demise after an icky encounter with some helicopter blades, Shatterstar has had a far more distinguished career in comics. After co-forming X-Force, he stayed with the team throughout much of the 1990s, He grew especially close to Rictor, his earth-shaking teammate, and the pair eventually left the team together. After a few years out of the spotlight, Shatterstar resurfaced in Peter David and Valentine De Landro'sX-Factor. While both were members of X-Factor Investigations, Shatterstar and Rictor's once-ambiguous friendship quickly evolved into one of Marvel's most celebrated romantic relationships. Tan's off-duty look, which he sported when he applied for a spot in X-Force, draws several stylistic notes from the more streamlined black-and-white outfit Shatterstar wore inX-Factor. Since that title ended, Shatterstar has served as an occasional supporting character in the X-Men's adventures.

17 BLACK TOM CASSIDY

Although he didn’t have a huge role to play inDeadpool 2, Black Tom Cassidy has a long history duking it out with Deadpool and the X-Men. In the movie, Jack Kesy's Black Tom appeared as one of the most intimidating inmates at the mutant prison where Deadpool was held. In comics, Black Tom was created by Chris Claremont and Dave Cockrum in 1976'sX-Men#99. The Irish mutant has the somewhat strange ability to channel energy blasts through wood, and he eventually gained some plant-controlling powers through his secondary mutation. While Tom was never the kind of villain who threatened the world, he could usually be found scheming alongside his partner-in-crime, Juggernaut, or battling his cousin Banshee, the X-Men's supersonic screamer.

Although Black Tom and Juggernaut didn't share any scenes together inDeadpool 2, Tom was one of the first villains Deadpool encountered during his solo adventures. In Fabian Nicieza and Joe Madureira's 1992 miniseriesDeadpool, the two mercenaries clashed over a disputed claim to another villain's will. In 1994'sDeadpool: Sins of the Past, by Mark Waid, Ian Churchill and Ken Lashley, Tom played an even bigger role as the story's main villain. After having a piece of wood implanted into his body to enhance his powers, Tom tried to capture Deadpool so he could use Wade's healing factor to stabilize his condition.

16 NEGASONIC TEENAGE WARHEAD

Negasonic Teenage Warhead was one of the most surprising breakout characters from 2016'sDeadpool. And in Deadpool 2, Brianna Hildebrand's explosive young X-Man came to Deadpool's aid once again. When Grant Morrison and Frank Quitely created Negasonic in 2001'sNew X-Men#115, she was only around for a few moments before she perished in a massive Sentinel attack that cost millions of lives. However, after Hildebrand's Negasonic got rave reviews inDeadpool, Negasonic returned to comics in 2016'sDeadpool & the Mercs for Money#1, by Cullen Bunn and Iban Coello. Although Ellie Phimister initially only had precognitive abilities, she gained reality-warping powers, super-strength and a new short-haired look inspired by her cinematic counterpart when she returned to comics.

SinceDeadpool 2had almost twice as many characters asDeadpool, Negasonic didn't have as much screen time in the sequel. Although she had a new girlfriend and became a full member of the X-Men, Negasonic was largely reduced to serving as a supporting player during the movie's fight scenes. After the film's climactic battle, she just walked out of the movie to take a group of young mutants back to the X-Mansion. With some help from her girlfriend Yukio, she also repaired Cable's time-travel device in one of the movie's post-credits scenes.

15 YUKIO

In the lead-up toDeadpool 2's release, the identity of Shiori Kutsuna's character was something of a mystery. Since she seemed to display electrical powers, most fans assumed that she was a version of Surge, a young mutant who was a member of the New X-Men in the 2000s. However,Deadpool 2revealed that Kutsuna was actually playing Yukio, a young X-Man who was also Negasonic Teenage Warhead's girlfriend. While she still used her Surge-like electrical powers to help out in the movie's fight scenes, most of her dialogue consisted of her and Deadpool saying "hi" to each other repeatedly.

In comics, Yukio is a considerably different character who's one of the X-Men's most trusted human allies. Originally, Yukio was a Japanese assassin who was created by Chris Claremont and Frank Miller in 1982'sWolverine#1.Although Yukio and Wolverine initially met as enemies, the two fighters became allies, and she eventually took in Logan's adopted daughter Amiko. When the X-Men were in Japan, Yukio became extremely close friends with the X-Men's Storm. In 2013'sThe Wolverine, Rila Fukushima portrayed a slightly different version of Yukio on the big screen. While she was still a skilled fighter who worked closely with Logan during his adventures in Japan, this version of Yukio had the mutant power to see how people will die. It's currently unclear what, if any, connection Fukushima's Yukio has to Kutsuna's Yukio in Fox's cinematic X-Men universe.

14 THE X-MEN

In one ofDeadpool 2's funniest moments, Deadpool narrowly avoided having a full-fledged team-up with the X-Men. While the mutant mercenary was complaining about the lack of X-Men in his movies, a full team of X-Men made a quick appearance behind him before silently hiding behind closed doors. This group included most of the cast of 2016'sX-Men: Apocalypse. The team consisted of James McAvoy's Professor X, Nicholas Hoult's Beast, Evan Peters' Quicksilver, Tye Sheridan's Cyclops, Alexandra Shipp's Storm and Kodi Smit-McPhee's Nightcrawler. Along with Sophie Turner's Jean Grey and Jennifer Lawrence's Mystique, this team of X-Men will make their next appearance in 2019'sX-Men: Dark Phoenix.

Since the new X-Men movie andDeadpool 2were filming at the same time,Dark Phoenixdirector Simon Kinberg actually shot the X-Men's cameo, which was then digitally inserted into the background of the Deadpool scene. This cameo also added another layer of confusion to the X-Men's already-complex cinematic timeline. Theoretically,Deadpool 2takes place in the present day, whileDark Phoenixis set sometime during the 1990s. In the scene, Quicksilver was even wearing a shirt depicting the iconic '90s rock band Nirvana. SinceDeadpool 2has so many time-traveling antics, it's best to assume that they were able to co-exist in the same place as the result of Deadpool messing with the timestream.

13 PETER (WISDOM)

When Rob Delaney's Peter showed up as a member of X-Force inDeadpool 2's trailers, he was a complete surprise. Instead of having any kind of mutant power or martial arts skill, Peter was just a normal, middle-aged man who joined X-Force. Although he didn't initially seem like he was based on any specific comic book character, some of the film's promotional materials suggest that Peter is secretly a less impressive version of Peter Wisdom, a mutant secret agent. For instance, Peter's Twitter profile indicates that his last name begins with a "W," and Peter's LinkedIn profile says that he's a sales manager at the "Excalibur Cutlery Co."

Shortly after Pete Wisdom was created by Warren Ellis and Ken Lashley in 1995'sExcalibur#86, the mutant joined Excalibur, a British offshoot of the X-Men that included characters like Colossus and Nightcrawler. Wisdom also has the mutant ability to generate "hot knives" of plasma energy from the edge of his fingertips. Like his probable cinematic counterpart, Wisdom also had a very brief stint as a member of X-Force in comics. After Ellis and Whilce Portacio took over the series, Wisdom joined X-Force and served as its leader for a few issues starting with 2000'sX-Force#102. Both Peter and Pete Wisdom walked away from X-Force after narrowly escaping death.

12 BEDLAM

Although Terry Crews' hit comedyBrooklyn Nine-Nine was recently saved from an early demise, Bedlam, his character inDeadpool 2, wasn't so lucky. When Deadpool was assembling X-Force, Crews' Bedlam seemed like a standout candidate. With his ability to manipulate electrical fields, Bedlam could short-circuit electronic devices and the electrochemical signals in the human brain to cause a variety of unpleasant sensations. However, Bedlam perished a few moments after his introduction when a botched parachute landing sent him flying into an oncoming bus.

In comics, Bedlam had a slightly longer tenure with X-Force before his embarrassing end. Jesse Aaronson and his brother Terrence were originally introduced in the alternate reality storyline "The Age of Apocalypse" in 1995'sFactor X#1, by John Francis Moore and Steve Epting. A few years later, Moore and Jim Cheung brought Bedlam into the Marvel Universe in 1998'sX-Force#82. After befriending Domino, Bedlam joined X-Force to help the team battle his unhinged brother. Although Pete Wisdom helped him develop creative uses for his mutant powers, that incarnation of X-Force broke up after a relatively short time together. In 2003'sUncanny X-Men#423, by Chuck Austen and Ron Garney, Bedlam was kidnapped by an anti-mutant hate group called the Church of Humanity. Along with several other mutants, he was strung up outside of the X-Mansion, where he later perished from his injuries.

11 CABLE'S FAMILY

InDeadpool 2, Cable travels to the present to save his family from being taken out by an adult version of Julian Dennison's Firefist in the future. At one point, Cable mentioned that his daughter was named Hope, and Islie Hirvonen briefly portrayed her during a flashback sequence. In comics, Hope Summers, Cable's adopted daughter, has been at the center of his life for the past decade. After most of the world's mutants were depowered, Hope was the first new mutant born in years in 2008'sX-Men#205, by Mike Carey and Chris Bachalo. After several competing factions tried to claim her for their own purposes, Cable took Hope into the future, where he raised her to be a competent young hero in her own right.

Although she was never named inDeadpool 2, Cable's wife, who was played by Hayley Sales, also made a brief appearance in a flashback. In the Marvel Universe, Cable has had two wives, and both of them met early ends. His first wife, Aliya Dayspring, was created by Fabian Nicieza and Art Thibert in 1993'sCable#1, and she ultimately perished in battle. After Cable adopted Hope years later, Cable married a woman named Hope in 2008'sCable #7, by Duane Swierczynski and Ariel Olivetti. After they raised young Hope together for a few years, the elder Hope perished, and Cable officially named Hope in honor of her late adoptive mother.

10 VANISHER

While a handful of eagle-eyed fans noticed that X-Force had an invisible member inDeadpool 2's trailers, Brad Pitt's Vanisher was still a surprise when he appeared in the movie. For most of his time onscreen, he was completely invisible, but audiences got a quick glance at his face while he was being fatally electrocuted by some power lines. Created by Stan Lee and Jack Kirby in 1963'sX-Men#2, the Vanisher was the second villain the X-Men ever faced. While his cinematic counterpart was invisible, the curiously-named Telford Porter was, naturally, a mutant teleporter in comics. After appearing in a few stories during the earliest days of the X-Men, the Vanisher only made a handful of appearances over the next several decades.

Like Pitt's Vanisher, the Vanisher also served with X-Force in comics for a brief time. After being captured by the team, Porter was forced to join the group in 2009'sX-Force#11, by Craig Kyle, Chris Yost, Clayton Crain and Alina Urusov. He was basically X-Force's chief mode of transportation until he seemingly perished and returned to a life of low-level crime. It's also worth noting that Pitt portrayed the vampire Louis de Pointe du Lac inInterview With A Vampire, a 1994 movie that was part of a running joke throughoutDeadpool 2.

9 STAN LEE

Unlike most other movies based on Marvel's characters,Deadpool 2 didn't actually feature an appearance from Stan Lee. However, that doesn't mean that his presence was totally absent from the film. While Lee played a DJ in 2016'sDeadpool, the Marvel icon appeared as a bystander on the street in the David Leitch-directedDeadpool 2teaser that ran in front of 2017'sLogan. While his part was cut out of the theatrical version of the teaser, it was included when the brief scene was released online.

Taking a note from Marvel's Netflix shows,Deadpool 2includes a few other images of Lee throughout the movie. In shows likeDaredevilandLuke Cage, Lee makes fleeting appearances in advertisements as the N.Y.P.D.'s Captain Irving Forbush, a version of the old Marvel comedy hero Forbush Man. While Lee wasn't named inDeadpool 2, a large mural of Lee could be seen painted on the side of a building during the movie's prison truck sequence. Earlier on in the movie, a bust of Lee could be seen for a few seconds while Deadpool was walking through the X-Mansion. Naturally, Deadpool broke the bust while he was goofing around in Professor X's motorized wheelchair.
