Wade had conflicting memories of his childhood. He once recalled that his father abandoned his mother while she was pregnant with him and she took out her anger on him until, as an adult, he beat her instead. He later recalled that his mother died when he was five and that his father, an army officer, became abusive, causing Wade to grow up to be a thug and criminal. When his father got his act together and tried to rein in his son, one of Wade's friends shot and killed him. However, he told a writer that his father was a teller of bad jokes who abandoned him and his mother while he was a boy. His mother turned to humor, alcohol and home shopping networks as a coping mechanism. He believed that he ran away from home so that his mother wouldn't need to spend what little money she had left on him.
However, it was eventually revealed that his parents were still together, living in Canada and had kept Wade's room as he had left it but Wade himself did not recognize the house, his parents or his room when he returned there as an adult.
After leaving home, he appears to have joined the U.S. Army Special Forces but despite his superior skills, he was drummed out for not following orders that conflicted with his moral code. After a failed suicide attempt just before his nineteenth birthday, Wade was invited to join a clandestine group of CIA-sponsored mercenary assassins thanks to his military record, assured that his targets would all deserve death.
Little is known of Wilson's subsequent activities with this group. At one point he was active in Tangier, Morocco where he romanced a woman named Francie. When this relationship soured, he traveled throughout Asia, and was hired in Japan by a crime lord, the Boss, to infiltrate a sumo-wrestling ring owned by a rival criminal, the Oyakata. Wilson spent three years as a wrestler under the Oyakata's tutelage and became romantically involved with his mentor’s daughter, Sazae. When the Boss finally ordered the Oyakata's murder, Wilson refused to complete his assignment, allegedly the first time he had ever done so, and relocated to the United States.
In America, Wade met and fell in love with mutant teenage prostitute Vanessa Carlysle, with whom he shared dreams of a better life. Wilson was subsequently hired by Middle Eastern interests to assassinate a blind British Government operative named Althea, also known as Blind Al. Upon arrival to the Zaire base where she was stationed, he killed everyone except for Al who had fled.
Those who put the contract out on Al sought vengeance for his failure by targeting Vanessa, who was rescued by Zoe Culloden, an employee of the inter-dimensional firm Landau, Luckman, Lake, and LeQuare. Culloden was keeping Wilson under surveillance, believing he was destined to play a vital part in a potential threat to the world. Learning that he had developed 34 inoperable cancerous tumors, Wilson broke up with his girlfriend Vanessa rather than force her to remain with a terminally ill man. He even gave up his chemo treatments, not wishing to prolong things.
Back in Canada, he was offered hope in the form of Department K, a special weapons development branch of the Canadian government. Wilson became a test subject in Department K’s branch of the joint U.S./Canadian superhuman enhancement project, the Weapon X Program; his cancer was temporarily arrested via the implantation of a healing factor derived from another Department K agent, the mutant adventurer Wolverine.
Wilson was active in a covert field unit alongside the near-invulnerable Sluggo and the cyborgs Kane and Slayback. Vanessa herself was later affiliated with the team after having manifested mutant shapeshifting abilities, calling herself Copycat.
During one mission, Wilson killed his teammate Slayback. Shortly thereafter, his healing factor began to destabilise, bringing his cancer back from remission and causing deformities in his flesh. As a result, he was rejected from the Weapon X Program and sent to the Hospice, allegedly a government facility where failed superhuman operatives were treated. However, unknown to the Canadian government, the Hospice's patients served as experimental subjects for Doctor Killebrew and his sadistic assistant Ajax (known then as the Attendant), with the patients placing bets in a "deadpool" as to how long each subject would live. Killebrew subjected Wilson to various torturous experiments for his own deranged satisfaction.
In due course, Wilson formed a romantic relationship with the cosmic entity Death, who regarded him as a kindred spirit. Wilson started trying to kill himself, to join Death - going so far as to start taunting Ajax by saying his real name (Francis) over and over, which earned him the respect of his fellow Hospice patients. Then Ajax, angered by Wilson’s taunts, lobotomized Worm, the closest thing Wilson had to a friend. At Death’s prompting, Wilson killed Worm to end his suffering.
However, under Killebrew's rules, any patient who killed another was to be executed; Ajax subsequently tore out Wilson’s heart and left him for dead, but Wilson’s thirst for vengeance was so strong that it jump started his healing factor, regenerating his heart, although not curing his scarred body. Wilson then escaped the now-empty room and attacked the guards, making his way to Ajax. Wilson shot him in the chest with two automatic rifles, leaving him for dead. Taking the name Deadpool, he escaped from the Hospice with his fellow patients.
Following his escape, Deadpool served for a time as an enforcer alongside the surgically altered criminal Hammerhead. He soon returned to his freelance mercenary activities, donning a costume in keeping with his new identity. At some point during his mercenary career, he was employed as an assassin by Wilson Fisk, the Kingpin of crime. He also clashed with Wolverine, at that time a spy for the Canadian government. At some point during these years, Deadpool caught up with Blind Al and kept her a prisoner in his home. Al’s attempts to escape only resulted in death for those whose help she sought, leaving her no choice but to resign herself to captivity.
Some years after escaping the Hospice, Deadpool, perhaps seeking compensation for the injuries inflicted upon him by Killebrew, returned to the Canadian government and was treated by Doctor Walter Langkowski, the bestial Sasquatch of Canada’s super-team Alpha Flight. He also acquired a teleportation device around this time.
Deadpool soon found government work unsuited to his temperament, and he abandoned this endeavor. Hired by the criminal genius known as The Wizard, Deadpool at first went to the wrong address and received a job impersonating the criminal Hobgoblin. When again contacted by The Wizard, he joined with fellow criminals the Taskmaster and the Constrictor (Frank Schlichting) in a short-lived version of the Frightful Four.
Afterwards, Wade was hired by Francis Talbot to use a time machine and a gun that erased people from existence in order to alter American history so that his family could profit the most from America's various wars, eventually making Talbot a world leader. This brought Deadpool into conflict with Cable for the first time. Cable managed to erase Talbot from existence, thereby restoring history to its rightful place, though seemingly intertwining Cable and Deadpool's fates.
Through his connections in the mercenary world, he would find employment with the time-traveling arms merchant Tolliver, in whose service he was reunited with Sluggo and Copycat. Unknown to Deadpool, Tolliver subsequently sent Copycat to impersonate another mutant mercenary, Domino. Deadpool also recruited a man named Weasel to act as his weapon supplier, and the two became fast friends, despite numerous acts of violence against him.
After some time in Tolliver's service, Deadpool was sent to kill Cable, the mutant soldier from the future who was in fact Tolliver’s father and in whose company Copycat was impersonating Domino. However, Deadpool met defeat at the hands of Cable and his new charges, the young mutants in training known as the New Mutants.
When Cable reorganized the New Mutants as X-Force, Tolliver was seemingly slain in battle with them, setting off a search by his various mercenaries for the advanced technology he had left behind. Deadpool’s participation in the search was interrupted by the surprising interference of Slayback, who had cybernetically reconstituted himself after being slain by Deadpool and was eager for revenge. In the course of the ensuing battle, Copycat was gravely injured, and Deadpool sacrificed part of his healing ability to save her life.
Deadpool helped X-Force member Siryn against the Juggernaut and her uncle, Black Tom Cassidy, who had forced Killebrew into their service. Deadpool developed a strong attachment to Siryn, who only partially returned his feelings.
Unsure of his worthiness, Deadpool sought out Copycat, only to find she was now dating Kane. Deadpool fought both Kane and Wolverine, who had been sent to check on Kane by a mutual friend. Deadpool was subsequently abducted by information brokers seeking a cure for the Legacy Virus but was rescued by Wolverine and the mutant mercenary Maverick.
He teamed up with Siryn again for a mission. Together they escaped from being kidnapped by Dr. Weisman. Shatterstar was forced to battle a mentally unstable Deadpool.
Deadpool was tracked down by Sabretooth and invited to join a new Weapon X Program. Impressed by Weapon X’s upgrade to his healing factor, he agreed to join, but soon found the organization's methods to be too bloody, even for him. After the death of Copycat at the hands of Sabretooth, he confronted the Director, only to have his healing factor reversed to the point where he again lost physical cohesion and died.
The lingering effects of Deadpool's healing factor upgrade resurrected him, leaving him an amnesiac. A chance encounter with Weasel later restored his memory, and he discovered that four other individuals had laid claim to the Deadpool name in his absence. These impostors were aspects of his own personality given form by a device called the Gemini Star, wielded by T-Ray, who had been hired by the intergalactic villain Thanos. Thanos himself was enamored of Death and became jealous of Deadpool’s relationship with her. T-Ray intended to use the Gemini Star to manifest and extinguish every aspect of Deadpool’s personality, leaving him an empty shell; however Deadpool damaged the device, causing his personality fragments to be absorbed into T-Ray and render Ray comatose. With T-Ray out of the way, Deadpool claimed his identity as the true Wade Wilson once again.
Both Deadpool and Cable became involved with a terrorist plot aimed at unleashing the shape-shifting "Façade Virus" upon the world. Both were infected with the virus, with merging their DNA structures being the only way they could survive. As a result, each man had some of the other's DNA sequences within them. From then on, whenever Cable used his teleporter to "bodyslide", both he and Deadpool teleported together -- sometimes literally (a "bodyslide by one" resulted in them being badly integrated into a single body, forcing a messy separation, which, thanks to the DNA shared with Wade, Cable was also able to recover from). An additional result of the Façade Virus in his system was that Deadpool's skin was temporarily cured of the hideous tumor-scarring. This result was corrected when Cable shut down all infections of the virus worldwide.
Cable was achieving the peak of his abilities, seeking to become a world leader ushering a new era of peace. Cyclops worried about his son, and hired Wade to find and assemble pieces of a teleporter meant to stop Cable if it came to that. In an attempt to unite the world, Cable deliberately set the world's leaders against him, by threatening to throw their missiles into the sun. Deadpool and the X-Men mounted their attack on Providence, whereupon Deadpool promptly turned on the X-Men, siding with Cable. Cable confessed to wanting to become a martyr, to show the governments that they could achieve something by working together.
In an attack by the Silver Surfer, Cable burnt out his powers and narrowly escaped death when Deadpool removed the telepathic and telekinetic parts of his brain via mini-teleporter. Cable was badly injured, and Wade then set out to recover some techno-organic matter to replace the damage. Deadpool encountered Agent X and the Fixer during his mission and was ultimately successful, which sadly left him unemployed thereafter. Cable felt guilty for Deadpool's status as a renegade mercenary being corrupted by his heroism, and began to covertly hire him for missions, without revealing that he was the one doing so.
Deadpool would later rescue Cable again, teleporting through several alternate worlds to retrieve him when he became lost. Cable returned the favor by repairing Deadpool's brain damage before his powers burnt out once more, leaving his personality and powers unchanged.
Cable's "Death" & Penetraitor
Providence was attacked by the Hecatomb, and Deadpool came to help. He arrived too late to fight the alien, but was able to help Cable to fight off the Marauders. In the end, Deadpool realized Cable wouldn't trust him with important tasks, and was sent home alone while Cable seemingly perished with Providence. Deadpool went to Rumekistan to pay his final respects to Cable, and while he was there, was asked to stop Wolverine from destroying a Hydra base. Minutes before Wolverine found Weasel at the base, Wade found him in a suit capable of teleportation, calling himself the "Penetraitor". Quickly decapitating Deadpool, Wolverine began to kill the Hydra agents, leaving ones that were strapped into suits similar to the Penetraitor's. They activated the suits to escape, but disappeared. Weasel explained that they were rigged to send the users to Guantanamo Bay, and Bob was able to reattach Deadpool's head. Bob, Weasel, and Wade returned to Rumekistan to finish paying their final respects, when Deadpool and Bob disappeared in a flash of light due to the now damaged suit Weasel wore.
Joining the X-Men
Deadpool would eventually make his way to Utopia in an attempt to become an X-Man, though they quickly rejected him. Since they couldn't just let him go, they pretended to bring him in on a probationary membership under the watch of Domino. Deadpool tried to get in the X-Men's good graces by killing Mark Kincaid, who had been claiming that the X-Men had kidnapped his daughter and were holding her against her will (part of Norman Osborn's plot to weaken the X-Men). When his plan began to fall apart, Osborn instead tried to use the situation to further discredit the X-Men by killing Kincaid and blaming Deadpool (who had publicly and falsely claimed X-Men membership), but Deadpool had set everything up to make the X-Men heroes again in the eyes of the public. This convinced the X-Men to reluctantly give Wade full membership.
He seemingly stayed on Utopia, and squatted in Loa's quarters during Necrosha. When Loa was attacked by the Cortez, Delgado, and Mellencamp, who were searching Magneto to kill him, Wade first intended to team-up with them, unknowing that Magneto was now an X-Man but was soon asked by Cyclops to battle them, without killing. He quickly realized (in disobeying) that wouldn't be a problem as the Acolytes were regenerated by the T-O virus. Severely beat up, he was saved by Loa, whose powers were revealed to be fatal to the returned, so Deadpool used her as a projectile against them.
Deadpool joined Wolverine and Archangel's Black Ops X-Force team to proactively eliminate threats to the mutant race with the only rule being that no one, not even the X-Men, could ever know that they exist. After one of their first missions, which ended with the team killing Apocalypse, who was reincarnated as an innocent child, Deadpool called a meeting to discuss his moral doubts about killing a child. During this meeting, Archangel told Wolverine that, despite being employed by Archangel for over a year, Deadpool never cashed any of the checks for his services. Later, in the Deathlok team-up, X-Force was taken into The World to look for the origin of the mind-controlled army. There was also some bad tension between Deadpool and Fantomex, which leads to them going different ways. Deadpool ends up being the one to kill The World's Father by cutting his head off then putting a sword through it to show the rest of the team. Fantomex is surprised, and they leave in silence.
As part of his plan to stop the recently-unleashed Red Onslaught, Magneto recruited Deadpool into an army of super-villains to help the heroes fight the Onslaught in Genosha. This team successfully turned the tide of the battle against the Red Onslaught and his Stark Sentinel in favor of the heroes, and allowed the Scarlet Witch and Doctor Doom to cast an inversion spell to alter the axis of the Onslaught's brain.
However, the spell affected all those present in the island, including Deadpool, who had his pacifist personality take control of his mind and body, and become the Zenpool. When Wade discovered Evan Sabahnur had become Apocalypse and was planning on detonating a gene bomb to kill everyone who wasn't a mutant on the planet, Wade tried to convince him into becoming good again, and also helped the Astonishing Avengers stop the inverted X-Men. After much effort, Wade managed to convince Apocalypse into helping him prevent the Axis from killing the White Skull (the inverted counterpart of the Red Skull). After Doctor Doom and the Scarlet Witch managed to cast a reinversion spell, Wade returned to his Deadpool persona. However, as an after effect of the reinversion spell, Wade regained his conscience.
Age of Apocalypse (Earth-295)
Obsessed with feeling pain, "Dead Man Wade" Wilson became one of Apocalypse's Pale Riders, a team formed by Apocalypse's chief assassins. His teammate Danielle Moonstar took great pleasure in inflicting pain upon him. When Apocalypse learned that Nightcrawler was seeking out Avalon, he sent Wade and the other Pale Riders to follow him and destroy the refuge.
Along the way, Danielle's torture of Wade annoyed their teammate Damask to the point where she strangled Moonstar to death. Watching the woman killed unnerved Wade even further.
They succeeded in tracking Nightcrawler to Avalon and launched their attack. However, witnessing Wade's brutal attack on the innocent people of Avalon convinced Damask to defect and attack him. Her initial attack failed, however Nightcrawler put an end to Wade, decapitating him by teleporting away while holding his head. His body was left where it fell as the attack continued.
He was later resurrected among the Alpha mutants to enforce the ranks of Weapon Omega, and leading a troop of Infinites, and was later recruited by Dreadpool to root out the remaining members of the Deadpool Corps. He and the rest of the Evil Deadpools were eventually killed in a war between the Evil and Good versions of the Corps'.
This version of Deadpool was thought to be dead after Sabretooth broke his neck in a reality that was controlled by Sentinels. It was later revealed that any incapacitated members of Weapon X and the Exiles had been kept in stasis. Deadpool was one such member. He was revived by an alternate version of Dr. Strange who was attempting to research a cure for Mimic who was frozen in stasis due to injuries received fighting King Hyperion. After being revived, Deadpool instantly murdered Strange by snapping his neck. Deadpool took over the Exiles' base, unfreezing She-Hulk, using her as a potential ally. However, he was later defeated by Mimic, who had been revived earlier. Mimic had absorbed Deadpool's healing factor. After the battle, She-Hulk judged Deadpool guilty of various murders she had witnessed him committing. She then smashed him into a pulp. This version of Deadpool is presumed dead.
Ultimate Deadpool (Earth-1610)
Wadey Wilson was a sergeant who after surviving death-defying action in the Wakanda Wars in the early nineties took the name Deadpool. His true face had no skin and portions of his skull were missing, covered by a clear plastic helmet that made his face appear human-shaped when masked.
Deadpool was a considerable anti-mutant human supremacist hired by the Genoshan government to hunt down mutants on live television as sport.
As one of the Reavers who assaulted the X-Men's X-Mansion during a visit from Spider-Man, he and his team used disguising technology to impersonate the X-Men and surprise them one by one with mutant-gene targeting stun guns. After capturing the X-Men, Deadpool also captured Spider-Man as a "bonus".
While transporting Spider-Man and the X-Men to Krakoa, Deadpool showed some respect to Spider-Man's secret identity after stopping one of his men from unmasking him, possibly due to Deadpool's odd sense of "respect" to mask wearers.
When Deadpool was unmasked it appeared that he was actually Professor X, but this was quickly proved to be a holographic ruse, which Spider-Man could easily see through with his Spider-Sense. Eventually Spider-Man unmasked Deadpool's true facial identity, much to the shock and surprise of Spider-Man and the X-Men, while being broadcast live on television. This enraged Deadpool, causing him to fire his guns in a frenzy until Kitty Pryde phased through him, seemingly causing him to explode and apparently killing him. However, Deadpool miraculously survived his ordeal, as his battered figure appeared on Krakoa's shore watching the X-Men and Spider-Man leave the island while clutching to his recovered mask.
He was eventually killed by the Earth-616 Deadpool by getting stabbed through the chest with a sword.
House of M (Earth-58163)
A field commander Wade Wilson is mentioned in New Avengers #45, which deals with the Skrulls' involvement in House of M.
Marvel Zombies (Earth-2149)
Little is detailed about Deadpool’s life before the zombie plague arrived on Earth-2149, however it can be presumed that it followed much the same path as his Earth-616 counterpart. At some point he was infected, and attacked the Silver Surfer. He most likely fled the attack but also escaped the Power Cosmic zombies from getting himself incinerated and killed.
He later transported from Earth-2149 to Earth-616, calling himself the "Merc with half a Mouth" (due to his lack of most of his jaw) and exhibiting a wide range of knowledge, which he used to take out Jennifer Kale's magic, and then attacked her. He appears to be killed when Wundarr the Aquarian threw him and Kale retaliated by luring Deadpool into the blades of a nearby skiff, completely tearing him apart. However, as the "Prime Carrier" he was contained within A.R.M.O.R..
Deadpool, now reduced to only a head, managed to escape from A.R.M.O.R. Headquarters with the help of Simon Garth by using the base's teleporters to escape to the bottom of the sea, where Deadpool's head infected all of the Men-Fish. Garth was compelled to travel to the island nation of Taíno in the Caribbean Sea, where he told Black Talon about the zombie plague. Black Talon assumed control of Garth, and captured Deadpool's head. However, Deadpool soon escaped with the help of Garth after biting one of Black Talon's guard.
Deadpool Kills the Marvel Universe (Earth-12101)
In this reality, the X-Men brought Deadpool to Dr. Benjamin Brighton (also known as Psycho-Man) in an attempt to cure him of his insanity. Unbeknownst to the X-Men however, Brighton had, in actuality, been brainwashing his patients to do his bidding as opposed to curing them. Brighton's treatment failed to brainwash Deadpool, instead destroying his inner voices, replacing them with a single voice that knew that the entire Universe was just a lie, and encouraging him to kill non-stop. Deadpool would go on to kill the Fantastic Four, the Avengers, the X-Men, cosmic entities and even the writers of Deadpool Kills the Marvel Universe, before starting multiversal massacre.
Deadpool Kills the Marvel Universe Again (Earth-TRN664)
Through unknown circumstances, the villains of the world captured Deadpool and brainwashed him into becoming a sleeper agent, mindlessly killing pre-selected targets while imagining vivid fantasies of wondrous adventures with his allies.
After massacring the world's population of heroes, and even a few cosmic ones, Wade was freed from his programming, and decided to hunt down the world's villains in revenge.
Powers and Abilities
Genetically Enhanced Physiology: Deadpool's powers come from the experimentation he was submitted to by the Weapon X program.
- Healing Factor: Deadpool possesses a superhuman healing factor derived from that of the mutant Wolverine which allows him to regenerate damaged or destroyed bodily tissue with far greater speed and efficiency than an ordinary human. His head or any other limb can be reattached using this ability. While beheaded, Deadpool can still move his body normally. In small doses, Deadpool's blood has demonstrated the ability to heal others and extend their lifespans beyond their natural limits. When combined with Star Cells injected intravenously, it confers immortality.
- Foreign Chemical Resistance: Deadpool's body is highly resistant to poisons and most drugs. For example, it is extremely difficult, though not impossible, for him to become intoxicated (Blind Al made several references to Deadpool being hung-over since he once drunkenly spoke to the Teletubbies on the TV he was watching). He can, momentarily, be affected by certain drugs (tranquilizers) if exposed to a large enough dosage.
- Disease Immunity: The unique regenerative qualities of Deadpool's healing factor also extend to his immune system; he is immune to all diseases, infections, disorders, imperfection, and resistant to elemental extremes.
- Immortality: Deadpool's healing factor provides him with an endless lifespan by halting the aging process. His life span is extended to such a degree that an alternate reality version of him was alive and still in business as Deadpool 800 years in the future. He was also cursed with immortality by T-Ray on behalf of Thanos, in order to keep him away from Death.
- Telepathic Immunity: The healing factor causes his brain to be in a constant state of flux and regeneration, rendering him immune to psychics such as Cable, Emma Frost, and the Red Onslaught. Deadpool can be looped into a telepathic psi-link to communicate with others mentally, as he did while a member of X-Force, but actually reading his mind can be confusing, even to an accomplished telepath like Psylocke. This would not prevent him from being attacked psychically though.
- Possession Resistance: Similar to the telepathic immunity, Deadpool is able to remain in control of himself while supernatural beings are trying to take control of him. During Xaphan's attempt to take control of him, Wade was able to fight for control of his body. No one can touch his soul.
- Superhuman Strength: Deadpool is rated as having a low degree of superhuman strength allowing him to lift 800 pounds.
- Peak Human Speed: Deadpool can run as fast as a trained athlete.
- Superhuman Stamina: Deadpool's musculature generates considerably less fatigue toxins than the muscles of an ordinary human being, granting him superhuman levels of stamina in all physical activities. He can physically exert himself at peak capacity for several days before fatigue takes over.
- Superhuman Agility: Deadpool's agility, flexibility, dexterity, balance, and bodily coordination are enhanced to levels that are beyond the natural physical limits of even the finest human athlete.
- Superhuman Reflexes: His reflexes are far superior to those of even the finest human athlete. His auto-reflexes allow him to easily dodge gunfire and attacks even when not consciously aware of them.
- Superhuman Durability: Deadpool's bone and muscle tissues are augmented to levels that are considerably stronger and harder than human and the tissues are impervious to injury to an extraordinary extent. He possesses golden-proportioned body, and even without training his muscles are brawny and his body shape doesn't change no matter how many calories he intakes.
Master Martial Artist: Deadpool is an extraordinary martial artist, hand-to-hand combatant, and is a master in multiple unarmed combat techniques, including Savate. He has been shown fighting such amazingly skilled fighters as Wolverine and Taskmaster and even defeating them in hand to hand combat. This shows that Deadpool himself is among one of the most skilled fighters in the Marvel universe, although in some fights it has been attributed to him being unpredictable.
Master Assassin: He is a master of assassination techniques, espionage methods, covert operations, infiltration methods, escape artistry, marksmanship, and is highly skilled with many bladed weapons (frequently carrying two swords strapped to his back) and a number of other weapons including firearms.
Multilingual: In addition to English, Wade is fluent in Esperanto, German, Japanese, and Spanish.
Medium Awareness: After accidentally being transported to the Foundation of Reality by the Beyonder, Deadpool became consciously aware that he is a fictional comic book character - though he noted he had always known subconsciously - allowing him to break the fourth wall. Wade doesn't possess this ability at all times due to the constant changes in his brain. References to the fourth wall made by those with similar abilities to him can trigger his medium awareness.
Unpredictability: It is difficult for anyone to know what Deadpool will do at any given moment, given that he himself barely knows what he'll do at any given moment. This makes it difficult for most opponents to predict what he will do. Taskmaster, whose abilities allowed him to analyze and copy the mercenary's fighting style, once believed Deadpool always dodged to the left. Deadpool proved him wrong, however, by completely changing his fighting style on a whim, throwing off Taskmaster's abilities.
Mental State: His healing abilities render his brain unreadable to telepaths, but its constant healing also makes him highly unstable and prone to violent outbursts without the slightest provocation, at least against those he knows could handle. Even with his healing factor, Deadpool can still feel pain from damage taken, although he has a notably high pain tolerance. While it has been shown that Deadpool's condition may not be the source of his instability, it only makes it worse. In several flashbacks to his childhood, he has shown signs of instability.
Annoyance: Wade's incessant talking has also proven to make him a very irritating person to be around. Many heroes often find themselves at wits' end around him; this makes for poor ability to cooperate with him in team efforts. Domino once said that Deadpool's most lethal weapon is his mouth. He will blabber nonsense during the whole fight, distracting and maiming the opponent until the latter "surrenders or commits suicide."
Cure for Cancer: Wade's healing factor was specifically designed to replace his bodies cells as fast as they were being destroyed by his illness. Should his cancer be cured then his healing factor would be rapidly producing redundant new cells, which, if left unchecked, would cause horrible growths over the body and would eventually explode, as demonstrated on the Super Skrulls with Deadpool's powers.
Phobias: Deadpool has bovinophobia, which is the fear of cows. According to him, cows "scare the *#$% outta me", as he believes their stare to be chilling, like they're "waiting". He may also be scared of chickens, like Domino. This may also have been an attempt to find common ground with her, as he was later able to put one in her path to stop her. During Deadpool's adventure to save the multiverse from the Awareness, it was revealed that his worst fear is to be truly and utterly alone.
Mystical Curse: Deadpool was cursed for a short time by Loki, who claimed to be his father. The curse made him look like Tom Cruise, rendered his face totally invulnerable, and caused his life to "fall to ruin." The curse was removed when Deadpool reconciled with his true father, who he met in a bar without ever realizing who it was. This seems to contradict an issue of "Cable & Deadpool" when, in a conversation between Cable and Deadpool about their pasts and parents, Deadpool's father is shown dying when he was a teenager, however when questioned on the truth of the story by Cable, Deadpool responds, "I'll tell you the truth when you tell me."
- Deadpool often claims to be a mutant and an X-Man, which causes more or less violent reactions from actual mutants and X-Men. He first claimed to have a "mutant healing factor" in Wolverine (Vol. 2) #88, which could arguably be seen as true since his healing factor was derived from Wolverine's mutant ability. Later, the X-Men dressed him up in an X-Costume as a gag in Cable & Deadpool #8, prompting Deadpool to occasionally fixate on becoming a full member of the team. Often times he claims to be both a mutant and an X-Man, only to be corrected by someone nearby. As Deadpool has become more accepted by the X-Men and the mutant community, they have been less insistent on correcting his claims.
- When House of M Nathaniel Essex tried to drug him, he stated that Deadpool was a mutant due to resisting the drug, but Wade himself denied being one.
- A computer used by Rocket Raccoon identified Wade as a mutant.
- The 2016 film Deadpool depicts him as a mutant with an initially-dormant healing factor.
- The mutant nation of Krakoa does not recognize Deadpool as a mutant.
- Deadpool's name is Wade Wilson, as that's the name he used to sign up with the army. To his own satisfaction, Deadpool discredited T-Ray's claims to be the "real" Wade Wilson after Cable improved his mental stability and Wade poked several holes in T-Ray's version of events. However, due to both T-Ray and Deadpool being mentally unstable, neither's word can actually be fully trusted. In Deadpool's words, "It depends on which writer you liked best."
- Despite being an assassin, Wade is unwilling to kill children. He has only once murdered a baby, Threnody's monstrous baby, when defending Weasel's pregnant wife Clarice.
