Wade Wilson was born as a normal person into a highly dysfunctional family in a small town in the state of Ohio. He ran away as a teenager and bounced around the country, all the while getting military training from various sources until he decided to become a mercenary. He kept changing his identity whenever something went wrong with the mission. He moved to Canada where he met a man by the name of Wade T. Wilson. Since he was Wade W. Wilson, the name reminded him of his old self. When he was ordered to assassinate Wade T., he accidentally killed the target’s wife, Mercedes. In the end, Wade T. ran away to eventually become the voodoo mercenary T-Ray while Wade W. kept the name “Wade T. Wilson” and never changed it out of respect for his namesake’s wife. When he was diagnosed with inoperable brain cancer, he volunteered for a subset of the Weapon-X program that was attempting to imbue a normal human with Wolverine’s healing factor.
Since he is Wade T. Wilson, he has Canadian citizenship, allowing him entry into the Weapon X program. The procedure was a success, but Deadpool, who took his name from the pool that the officers and scientists bet in as to who would die next in the experimentation, became severely mentally unbalanced as a result of it. He escaped the facility and has been wandering ever since. Some people might speculate that before his name was Wade Winston Wilson his name was Jack though this isn’t confirmed.
Deadpool’s debut marked a very different version of the character. He was a serious, grim and professional assassin, with none of his personality trademarks intact. It would be in his solo book that his trademark character traits would finally emerge. These would include the dark randomness to his actions, his humorous bend, schizophrenic tendencies, his suicidal personal outlook, and his 4th wall breaking quips that would make him famous, along with his love for Mexican food. Recently Deadpool has been trying to be a hero.
Deadpool has been known for carrying a number of weapons and sometimes it is as if they appear from nowhere, this is often referred to as a ‘magic satchel’. Blind Al is also a significant catalyst in Deadpool’s personal development, as there is a clear love hate relationship which can vary from Blind Al being a mother-like figure to an abused hostage; sometimes within the same storyline.
His personality has changed somewhat now he has become mortal; yet he still takes risks, welcoming the idea of dying so he may once again be united with his love, Death. The same humor and incapability to take many battles seriously still remains, though his face no longer carries the scars from cancer or Weapon X.
Wade Wilson is a man shrouded in mystery. For instance: Wade Wilson may not be his real name and his back story may have been stolen (in-continuity) from another character. He remembers a mother who died of cancer when he was five, another mother who beat him during his teen years. He remembers a father who abandoned him in his childhood-years and yet another father who died in a bar room altercation when he was 17. That father was a good man but a militarie man whom was very strickt with Wade, to whom Wade rebbeled. He was shot by one of Wade’s friends, which caused Wade to be filled with remorse. The final father is the only one who is definitely real, all the other snatches and fragments of memories may be the result of his broken psyche. It is later revealed that the various conflicting memories of his family were implanted by a man named Butler, and that Deadpool had actually been forced to kill his own family while under Butler’s control.
He remembers an upbringing in Ohio, but even he recognizes that this may not be true. This mysterious young man joined and quickly excelled in military service, or at least the combat side of service. The strict hierarchy and rules didn’t jibe with the young man’s sense of self and his absolute need to rebel against authority figures, clearly military life was not for him and he was dishonorably discharged. The military did teach him two things: he was good at killing and he enjoyed it, so he quickly found work as a mercenary, though at first he only took on targets who he felt deserved to die.
Eventually he wound up in Japan as a Yakuza enforcer where he fell in love with one of the boss’ daughters. The young man’s mind was already in a state of radical instability, though, and he knew the relationship could never be, so he returned to America and ditched his previous moral code in addition to changing his entire identity, even his appearance, after each failed mission, fracturing his mind even more severely.
When an ordinary couple stumbled upon the wounded mercenary in the woods, they took him into their home, the woman even nurses him back to health, but again his unstable mind strikes and he becomes enamored with the young woman and envious of her life with her husband. So he burns their house down and kills her husband before accidentally killing her too. He takes the name Wade Wilson and believes himself to be the dead woman’s husband, but still returns to the mercenary trade.It was later found out in the Cable/Deadpool series, that this story was a lie, and Deadpool is the real Wade Wilson
It’s at this stage in his life that he meets the shape-shifting prostitute Vanessa Carlysle. The young couple quickly fall in love, both of them tainted by pasts they’d rather forget. Wilson’s possibly idyllic life is shattered, however, when contracts cancer and leaves Vanessa because he doesn’t want to burden her with his failing health.
Wilson joins Canada’s Department H, seeking a cure for his cancer, which they promised but never delivered on. Wilson built up his reputation working with the mechanized man Garrison Kane, fellow mercenary Sluggoand the suspicious Greg Teraerton. When Teraerton began to exhibit psychotic tendencies, Wilson killed him and was kicked out of Department H. He was sent to a facility called the Hospice and within that facility came under the dubious care of Dr. Ermys Killbrew’s “workshop”, a place for failed experiments. After being experimented upon multiple times, Wade is repeatedly visited by a hooded woman who comforts him and, after multiple visits, he falls in love with her. However the woman, it turns out, is the physical embodiment of Death, who Wade sees and can communicate with because he’s so close to dying.
Wanting to join Death he began taunting and defying his guards, hoping they would have him killed, but all the lead guard Ajax did was gladly sent him in for more of Killibrew’s excruciating tests. The guards began to bet on when patients would die next, throwing their money into a “dead pool” the winner of which would win the pot. To Ajax and Wade’s dismay, he continued to survive and Ajax wasn’t authorized to kill a patient unless that patient had killed another. When Wade finally attacks Ajax, the guard responds with incredible brutality, but accidentally triggers Wilson’s healing factor, allowing the mercenary to escape with a few of his fellow inmates. He mockingly dubbed himself “Deadpool” and went back to his mercenary lifestyle. Sometime later it is revealed Deadpool has become a father.
Deadpool and Cable’s paths cross once again when the cult known as the “One World Church” hires Deadpool to protect them. Cable and Deadpool fight but due to a teleportation error, the two are linked and one cannot teleport without teleporting the other thus it’s like the expression “You scratch my back and I scratch yours”. Although they start out as enemies and find it amazingly difficult to be in each others presence, the two manage to become somewhat of uneasy allies after some time. Deadpool is there when Cable constructs his own island nation. Deadpool, after some time, accepts Cable’s offer to join him on his island and the two become real friends, although neither of them would ever admit it. Deadpool even tells Cable about his origin, how he was the son of a military dad, and how Wade got in with the wrong kind of friends.
One of them, eventually killed his dad when he tried to take Wade out of a bar. Deadpool gets inspired by Cable’s way of life and tries to become a better person, stopping his former violent ways. This works out to some extend, but Cable and Deadpool clashed numerous times after that. One of their largest fights was when Wade sided with the pro-registration act group of superheroes during the Superhuman Civil War. Cable eventually took reign over the small European country known as Rumekistan. Deadpool was hired by the government of that country to stop this from happening and even shot Cable in the back.
Cable however managed to stop the bullet and defeated Deadpool and his teammates of other mercenaries. He then joined with Cable once again, this time vowing to stop his unnecessary violent ways. During one mission, Deadpool took an agent of Hydra named Bob hostage. The two made it out alive and soon Bob became somewhat of a sidekick and friend to Deadpool whenever he appears in the comics. Not soon after this, Cable vanished during an attack by the newly reformed Marauders right before the events of the Messiah Complex. Cable’s city was destroyed and Deadpool feared the worst for his good friend.
Cable however later resurfaced when he tried to safe-keep the first baby mutant that was born since M-Day. Deadpool found out about Cable’s mission and aided him in keeping the baby safe. They where attacked by various advisories such as the Marauders, the Purifiers and even some creatures named Predator X. After this, Cable made Deadpool promise to stop following him, and he told him that they would see each-other again. This however turned out not to be true. Cable was killed during the events of Second Coming. Deadpool was devastated. His former greatest enemy and now best friend was no more. He went back to Rumekistan (at least the thought it was Rumekistan) and tried to honor Cable by making the country a better nation.
Deadpool was hired by Archangel to be on X-Force in the search for Apocalypse. Deadpool was scouting a base to find out the plans for Apocalypse’s resurrection only to be captured and held captive. Later he was rescued by the rest of the team and informs them of the plan. They then head to the moon base where the Resurrected kid apocalypse (Genesis) is located. Unfortunately a new horsemen of Apocalypse took down Fantomex’s E.V.A. where the team was injured and Deadpool was left with Archangel where he helped keep Archangel well by feeding him Deadpool’s own flesh. Later when they finally reached the boy, the team comes to an agreement that the boy can be saved only for Fantomex to shoot Kid Apocalypse in the head. After this event, Deadpool does a recon mission only to realize that the Reavers and Lady Deathstrike are planning a attack on Utopia.
The team then goes against the Reavers until Wolverine got stuck fighting Lady Deathstrike, and Deadpool and Fantomex were blown away by the Reavers leaving Warren and Psylocke to fight the Reavers. After that Deadpool had a meeting with everyone except Fantomex to talk about the apocalypse event.
Deadpool then leaves the conversation saying “I don’t kill kids”. After that they learn that Deadpool never cashed any of Warren’s checks having them realize that Deadpool is not on the team for money. Soon after the team is attacked by Deathlock versions of the Avengers and a Deathlock approaches the team with an offer to stop their creation. He joins the team on their mission to the alternate Earth where all of Earth’s heroes have been made into Deathlocks. The team is attacked by Deathlock versions of themselves who are more deadly than the originals. Fantomex uses his misdirection to allow them to escape. Deadpool is the one who kills the source of this reality’s problems, world father by decapitating him.
Deadpool also accompanies the team into the Age of Apocalypse. While X-Force seeks out Dark Beast, Deadpool frequently comments on how he cant be trusted. When they are abandoned in the AoA universe he is mistaken for Dead Man Wade, his counterpart in that reality. X-Force fights their way through the Black Legion in order to free a mutant who can make portals in order to get home.
Through a number of adventures, the Kid-Apocalypse (now better known as Genesis) stayed with the team and formed a special bond with Deadpool. They where both misunderstood beings. Deadpool, a mercenary for hire whom was actually a better person then he led on, and Genesis, a kind boy with running towards a legacy of evil. Deadpool wanted to make sure that Genesis would never fullfil the horrible legacy he was bread for.
