Deadpool is depicted as having a regenerative healing factor, which not only prevents him from being permanently injured through enhanced cell regeneration throughout his body, but also causes psychosis and mental instability, as his neurons are also affected by the accelerated regeneration.
Throughout the entire movie, it is said that he frequently displays many different psychological disorders including attention deficit hyperactive disorder, manic depression disorder, and schizophrenia. One of the disorders Deadpool is diagnosed with is severe ADHD, also known as attention deficit hyperactive disorder.
Rather than a Wolverine blood transfusion, Ryan Reynolds' Deadpool is pumped full of an unnamed serum that awakens any latent mutant genes present in the victim's body. It turns out, Wade was born with a healing factor that never manifested itself. After the serum, Ajax tortures Wade until his mutation shows itself.
The most disgusting and pure evil form of Deadpool, Venompool has to be one of the strongest hybrid creatures in the history of the Marvel Comics Universe.
There it is established that the reason for Deadpool not regenerating is purely psychological, his low self-esteem is what stops him from returning to his normal appearance.
Revealed at one point that Deadpool saved Spider-Man's life after he died on the field of battle by giving him a transfusion of his mutated blood, this secretly executed Lazarus effect successfully keeps Peter breathing, but in the long run, results in some unintended consequences that see him live an unnaturally long ...
Along with his extra mutant powers, one of the things Stryker did to Wilson was have his mouth surgically shut, making him the perfect soldier in Stryker's eyes. In the post-credits scene his mouth is partially open.
Given Deadpool's established need to speak incessantly despite the situation, he would have unleashed a swarm of locusts he'd be unable to control. However, with his mouth sewn shut, Deadpool can better regulate the disgusting ability.
It has been revealed that at the time his healing ability was given to him, Deadpool suffered from some form of cancer; after the healing factor was given to him, it made his normal cells as well as his cancerous cells unable to die, giving him a heavily scarred appearance beneath his suit.
It's when Wade Wilson aka Deadpool (Ryan Reynolds) is stuck on the couch of his elderly blind roommate Blind Al (Leslie Uggams) while his legs re-generate, having been earlier torn in half by Juggernaut (oh yeah, that was pretty crazy, too). We first see the stumpy legs – and possibly more – as Wilson sits.
Yes, Deadpool feels every bit of pain as normal humans do. However, his regenerative ability allows him to heal from all injuries. While Deadpool can heal quickly, he isn't indestructible.
His emotions are often like a roller coaster ride without an operator and on full speed. He can be dependent and clingy to those who seem stable and strong. He also has a severe ADHD problem and finds it hard to focus on anything for an extended amount of time, similar to trying to talk to someone covered in bees.
In multiple comics over the years, it's been established that Deadpool's healing factor is more powerful than Wolverine's. Deadpool can survive anything. If his head is cut off, he'll regrow his body over a few weeks. He can heal almost instantly from pretty much any wound.
Determining who is stronger between Deadpool and Wolverine is subjective, with Wolverine being more accomplished and experienced, while Deadpool has an edge in skill, unpredictability, and healing factor. The outcome of a fight between them in Deadpool 3 would likely favor Wolverine.
The nature of Wolverine and Deadpool's healing factors are totally opposite, from the fact that Logan was born with his ability and Wade gained it through experimentation, to how each healing factor fundamentally works. However, despite being opposites, both healing factors are exactly that: healing factors.
While Wade does get inebriated if he drinks a lot of alcohol, his body's super-powerful immune system protects him from getting drunk easily, meaning that Wilson needs a lot of alcohol in his system before he can even remotely be affected.
His power is so effective that it allows him to be immortal despite him carrying his cancer. But that doesn't mean he is unkillable. One way of killing him is to put a mutation-dampening collar on his neck. It will disable his regenerative ability and allow the cancer cells to grow, thus deteriorating his body.
as easily as any other person's. In the case of dislocated bones, Deadpool has to manually set the bones back himself. And he can feel the pain. Note that Deadpool's healing factor does not render him immune to pain.
Unsurprisingly, Deadpool has flirted with Death (literally) and the entity seems to reciprocate those flirtations. Not happy with having another rooster in the hen house, Thanos has apparently cursed Deadpool with an eternal life so the merc can never truly remain with Mistress Death.
There's not really much one can do when facing an opponent whose prime ability is to never perish. Hence, Thanos would have no chance against Deadpool if he was facing him without the Infinity Gauntlet. Thanos can eradicate entire civilizations and wipe out half of all life in the universe with a snap of his fingers.
