Wade Wilson was a soldier and mercenary with enhanced reflexes and agility due to him being a mutant, putting him far beyond the average human. Six years later, after Team X broke up, Wade was captured and taken to Stryker's base at Three Mile Island, where he was experimented on for the Weapon XI project.
With the other powers, he had from several other mutants (including Cyclops optic beams, Wolverine's healing power, John Wraith's teleportation, Chris Bradley's nephropathy, and Wade's prized blades used as two retractable arm blades) he was ready to fight and kill Wolverine. Just as Weapon XI is about to decapitate him (at the command of Stryker), Victor later joined to help Logan as he shoves Deadpool away, and both of them fall into the reactor.
Logan falls over the edge of the reactor as Victor is caught jumping at Weapon XI and shot back. Weapon XI holds his neck as Logan kicks him into the nuclear reactor, his head falling off as he tumbles below, with the lasers still firing.
As Weapon XI prepares to attack Wolverine as he rescues the kids from Three Mile Island, he is suddenly shot through the head by the time-traveling Deadpool of the revised timeline. Deadpool tells Wolverine that he is “cleaning up the timeline” and shoots his alternate self several more times.
Due to Wolverine traveling back in time to January 1973, and preventing Bolivar Track from being assassinated by Mystique, and changing the significant events after that point, Team X was never formed. While he would later joke about the hardships of his childhood, he did state seriously that “family” was an “f-word” for him; his father had left a wrong impression before “bailing” on him when he was young.
At some point in time, Wade Wilson was a member of the Canadian Special Forces, moves to New York City, and befriended a bartender named Weasel. One day, Wade takes a job getting a pizza delivery boy to stop stalking a girl by threatening him.
After the bar fight was settled, Wade meets a prostitute named Vanessa Carlyle. They bond over their weird, messed up lives before starting a sexual relationship, which eventually evolves into a romantic one.
The next day, Wade and Vanessa go to the hospital, and he is diagnosed with terminal cancer in his liver, lungs, prostate, and brain. He tells Wade that he works for a facility that will not only cure him of his cancer but also give him incredible powers.
Becoming a Mutant Desperate to live and despite initially declining, Wade later reconsiders, made a choice to be cured for Vanessa, and leaves her alone in the middle of the night to undergo the procedure. Ajax injects Wade with a special serum that activates any dormant mutant genes in him, the mutations being meant to turn him into a superhuman to heal him from his cancer, but says that for it to work and because adrenaline is the serums' catalyst, they have to subject him to extreme stress for the mutation to occur.
Wade undergoes various torture techniques carried out by Angel Dust to trigger a mutation. After days of torture and no success, Wade eventually learns that Ajax's real name was Francis, and makes fun of the man.
Ajax then reveals that the program was intended to turn Wade into a super-powered individual, but as a super slave, where he would be auctioned off somewhere to become an assassin. During his time in the chamber, the drop in oxygen triggers a regenerative healing factor that cures his cancer.
Unfortunately, Wade's cancer cells were further enhanced, severely disfiguring his entire body in the process as his skin and face started to blotch up. Upon being released, Wade would curse at Ajax for his hideous form and headbutts Angel Dust, stealing a match from that she keeps in her mouth in the process.
Upon being sealed in the chamber once again, Wade took the match out and struck it, throwing it near the oxygen vent, thus generating a massive explosion that destroyed his confinement and the laboratory. Ajax goes down to see what happened, and Wade starts to fight with his increased strength and attempts to kill him.
Ajax gets the upper hand and overpowers Wade, impaling him with a bar, which he leaves bent. Hunting Ajax Dismantling an Organization Wade wakes up alive but horrified by his complexion.
He walks through the streets with a hood over his head, but the people that see him are creeped out and disgusted by his appearance. Weasel encourages Wade to make a suit and mask to disguise himself as he goes back to hunt for Ajax so that he can fix his face.
Inspired by Weasel, Wade became a vigilante, adopting the identity of Deadpool from the bar's fighting tournament. During this time, Wade moved into the home of a blind woman named Al while summing up the courage to reveal himself to Vanessa.
Following a string of leads from various syndicates, Wade eventually finds The Recruiter, who says what he knows about Ajax's whereabouts before Deadpool kills him. Deadpool's main target is Ajax, the man that gave him his powers and also horribly disfigured him.
The vans all come crashing to the end of the bridge, where one thug's head is sliced off with a chain, and another one gets gorily splattered against a sign on the highway. Deadpool lifts his mask to show his scars so that Ajax can recognize him as Wade Wilson.
Deadpool then makes a few more futile attempts to injure Colossus, but to no avail, both of his hands and right foot are also broken. Deadpool, with his limbs, completely healed, chooses to cut his own cuffed hand off, and hop into a dump truck on the freeway below, leaving his hand to give Colossus the finger.
Aftermath Deadpool rides the garbage truck back to his and Blind Al's place. After returning to the residence, Wade's hand starts to grow back slowly, gets convinced by Al into revealing himself to Vanessa.
Weasel then informs Wade that Vanessa went out back, and the latter heads there to look for her but only finds her purse, letting him know that she's been taken. Infuriated, and desperate to save his love, Wade arms himself with all the guns he owns that are in Blind Al's house.
The two have a brief reunion, but Deadpool knocks his old friend out, while reminiscing about Bob's family, and pulls the soldier away to safety. With Masonic Teenage Warhead's help, Deadpool manages to get atop of the aircraft carrier where Ajax is keeping Vanessa.
Ajax then prepared to kill Vanessa with another oxygen deprivation chamber and duels with Deadpool using their own weapons. During the battle, Deadpool threw one of his swords into the oxygen deprivation chamber, successfully saving Vanessa from oxygenation.
Deadpool continues his brawl until Ajax throws a knife into the mercenary's head, temporarily disorienting him. Vanessa, having broken free from the oxygen deprivation chamber, impales Ajax with her Deadpool's sword.
Colossus carries Masonic and Angel to safety while Deadpool makes sure Vanessa safely lands. Still, Ajax laughs and mocks Deadpool by informing the mercenary that there hadn't been a cure for his disfigurement the entire time.
Enraged after hearing how Ajax can't fix him after all that has happened, Deadpool pulls out a revolver and prepares to kill Francis. Ignoring Colossus' speech about heroism, who wants Wade to spare his enemy's life, Deadpool summarily executes Francis with the revolver, much to the mutant's disgust.
Deadpool reveals his disfigured form to Vanessa, but she didn't care what he looked like, for it was a face she was “willing to sit on,” with Wade saying he obtained a “super penis” from being experimented. After acknowledging a reference from Deadpool, Masonic said he was cool, leaving him baffled, as her comment wasn't mean.
However, this took longer than expected, and by the time Deadpool exited the booth, the older man had been shot dead. A disappointed Wade then sat down beside the older adult, took his yogurt, and began ranting about the presence of a phone booth, how long it takes to go into a superhero and to claim Wolverine probably would have been able to save him due to only wearing a tank top and jeans.
Deadpool continues his career as a contract killer, taking his business worldwide. Realizing that he is to blame for Vanessa's death, he pumps himself with a huge amount of cocaine, tries to kill himself by attempting to have polar bears devour him, drinking a bottle of bleach and walking on the edge of a building until he falls, before blowing up an apartment.
Wade has a near-death experience, meeting Vanessa, who tells him that his heart needs to be in the right place before they are reunited. During the battle, Wade tries to use Cable's weapons, which ends up triggering a concussive blast that throws them out of prison.
Seeing Vanessa in another near-death experience, Wade becomes convinced that he needs to save Russell from Cable. Assembling a team he names X-Force, Wade attempts to rescue Russell from a prison convoy.
During the mission, all the members of X-Force except for him and Domino die, and he fights Cable until Russell frees the Juggernaut. Juggernaut crashes the transport, tears Deadpool in half, and escapes with Russell.
Recovering at Blind Al's by regrowing his legs, Wade is visited by Cable, who wants to team up to stop Juggernaut and Russell. Russell is due to kill the Headmaster of the Essex House, an act that will put him on the path to become a prolific killer.
Wade agrees on the condition that Cable gives him a chance to talk to Russell and get him to stop. Wade, Cable, and Domino head to the Essex House and engage Juggernaut in combat.
Colossus, Masonic Teenage Warhead, and Audio arrive to help, and Juggernaut is defeated. Catching up with Russell before he kills the headmaster, Wade puts on a power-dampening collar and offers himself as the sacrifice instead.
Russell gives up on his vengeance at Wade's sacrifice, and Cable realizes that the bad future has been averted. Later, Wade gets Masonic and Audio to fix Cable's time-travel device and then uses it to save Vanessa and Peter.
The Westchester Incident In 2028, Charles Xavier developed Alzheimer's and suffered a massive seizure that injured 600 people, and killed seven mutants, including several members of the X-Men. Wade possesses a highly sarcastic and great sense of humor that irritates and annoys most of his enemies.
He feels no shame and can make a joke out of any situation, even after months of endless torture he was able to keep his sense of humor alive, despite it being shaken over some fear and shock over his subsequent transformation. He remains very movie-cultured, referencing The Matrix, RoboCop, Alien 3, Sent, 127 Hours, Cocoon, X-Men : Days of Future Past and Star Wars.
Wade himself is aware that he is a fictional character in a movie and belittles this by breaking the fourth wall and speaking directly to the audience. Despite his initial immaturity, Wade is a genuine, soft, good-hearted man, and in time became a very moral and heroic person to the point of sacrificing himself to save Russell.
Although he is a mercenary, he agreed to scare off a young girl's stalker without being paid for his troubles, revealing he can be affectionate. On matters of love, he can be surprisingly sensitive, having been forced to abandon his girlfriend, Vanessa due to his terminal cancer, he advised his taxi driver, Domineer to fight for the object of his affections, Rita.
After his near-death experience, this trait has died down, but he had not accepted her demise, so Wade irresponsibly uses Cable’s time travel device to save her. Mostly Wade considers their disguising nature and abiding by rules extremely tiresome, yet he pondered joining them after Vanessa’s death until he grew sick of the restraints of the team.
Wade also affected Colossus by encouraging him to behave more dubiously, such as during his fight with Juggernaut and even curse. In contrast, Wade has shown fondness towards Masonic’s girlfriend, Audio, as she seems to be the only person he does not mock or intentionally annoys, which is mutual.
The only X-Men member Wade actively respects seems to be Wolverine, which borders on sexual advances and even love though he was presumably joking. Shown able to produce intense concussive or heat beams, a single blast was able to decimate an entire factory tower.
While unknown, if Wade could manipulate technology himself, Stryker was able to use this power to send him commands, effectively controlling Weapon XI. Powers Deadpool was injected with a serum that activated any mutant genes lurking around in his DNA, and was subjected to extreme stress for it to work.
Minor injuries, like bullet wounds and broken bones, take mere minutes to recover. While full dismemberment takes hours to restore, which goes through a period of accelerated maturing, starting as an infant-like limb before becoming fully grown.
Even more, his healing powers leave him immune to any form of illness and contaminate, able to even cure himself of cancer that was previously ravaging his body. He also was unfazed when he crashed through a car's glass roof from a highway several miles above it.
This also grants him an enhanced tolerance to pain, making it hard to slow him down, to which even then he can quickly rebind, letting him continuously fight at full strength. Confined spaces could not limit his movement at all, allowing him to overpower and kill multiple attackers after landing in their car.
He even threw one of his bananas several feet into the wheels of a motorcycle while jumping through the air. Wade's accuracy was also displayed when he played speedball with Vanessa; he threw a ball directly into a hole, instead of rolling it.
Able to scale seemingly any terrain with no wasted timing or movement, his prowess outmatches some of the most accomplished circus aerialists and acrobats. Using a variety of free-running and parkour maneuvers, he is challenging to anticipate with his erratic and spontaneous movement.
To which, he can be highly impulsive without restraint, easily distracted or forgetful, and very random in his mood. Wade seems to be afflicted by what is commonly known as the Truman syndrome, a type of delusion in which the person believes that their lives are staged and that they are constantly being watched on cameras.
In the comics, Wade Wilson is a human who was put under experiments by the Weapon X program scientist Dr. Kill brew and his assistant Francis Fanny/Ajax due to his cancer. While the tests proved successful and did give Wilson superhuman abilities, cancer has reached his brain, which deformed his skin, turned him insane, and forced him to wear a mask and a suit as a disguise.
In fact, Wade Wilson before his transformation shares much more in common with the comic book counterpart due to his mercenary status and comedic nature. In contrast, the 2016 version is simply said to have been forcibly mutated via a serum with no connection to Wolverine whatsoever.
Concept arts indicate that the character was originally designed with a suit and mask, but was later reverted to lack those features. Weapon XI is mocked in the 2011 video game Marvel vs Cap com 3: Fate of Two Worlds.
This is a reference to the fact Deadpool can fire Cyclops' optic blasts from his eyes in the film. The 2016 film disregards the Weapon XI of the character, as in X-Men : Days of Future Past the formation of Team X has been avoided from history due to Wolverine's time travel.
In some theaters' Easter egg endings, Weapon XI's hand is seen reaching for his severed head. The regaining of his older consciousness, as well as his ability to speak, is probably because of the damage he sustained in the fall.
According to Bryan Singer, the mutants Rachel Summers, Locke, Deadpool, Nightcrawler, Gambit, and Jubilee were meant to appear in X-Men : Days of Future Past, but were cut out for running time purposes. Weapon XI from Kestrel (John Wraith), RL'and from Nightcrawler (Kurt Wagner) Both possess Cyclops' optic blast.
