Fighting Style(s)
As a mercenary and assassin, Wade is trained in many forms of deadly combat. He was also briefly a sumo wrestler.

In addition to his martial arts training, Wade has amazing strength as well as superhuman stamina, agility, and reflexes. Due to having Wolverine's health regeneration ability grafted to him, Wade is capable of recovering from nearly any injury, no matter how fatal it normally would be.

Arguably, due to his insanity, Deadpool's most powerful ability is his non-stop mouth.
Weapon(s)
Various Weaponry, Accelerated Healing Factor

Wade uses primarily pistols, katana, and explosives, but has been known to use just about any martial arts or modern weapon including sai, knives, and missile launchers. Due to his "outside-the-box" thinking (to put it mildly), he is often seen using unconventional weaponry, including a sheep cannon and a suit of armor made entirely of pork.

Wade acquired a teleportation device that he often uses. If malfunctions on occasion, which is reflected in his moveset.

Since Wade is legally insane and is fond of breaking the fourth wall (i.e. medium awareness), he is also able to use his own life and super meters as dangerous weapons.

Storyline
Background
Pre History
Wade Wilson became a mercenary at an early age, traveling the world and completing all sorts of contracts, including assassination. At one point, he became a sumo wrestler known as Chiyonosake, becoming romantically involved with the stablemaster's daughter, but fled when he was contracted to assassinate the stablemaster himself.

After spending some time in America, Wade learned that he had contracted terminal cancer. He joined a Canadian government collective known as Weapon X, and his cancer was cured by implanting the healing factor of Weapon X operative Logan into him. Wilson was placed into a covert field op team until he ended up killing one of his teammates.

Wilson was released into The Hospice, a facility for failed superhuman experiments. Unknown to the Canadian government, however, The Hospice was experimenting on their residents even further. Due to these experiments, Wilson was heavily scarred, and came close to death, forming a romantic bond with the personification of such.

Longing for his demise so he could be with Death, Wilson taunted the enforcer of The Hospice, known as The Attendant. In retaliation, The Attendant lobotomized Worm, the closest thing Wilson had to a friend within The Hospice. Death persuaded Wilson to put Worm out of his misery. However, any Hospice patient who killed another was punished by execution, no matter the reason. The Attendant ripped Wilson's heart from his chest.

Wilson's thirst for vengeance, however, was so great that it jump-started his healing factor, regrowing his heart and bringing him back to life (although his heavy scars remained). Vengeance was brought against The Attendant, as Wilson, now calling himself Deadpool, shot him twice in the chest.

Deadpool continued his mercenary life, eventually obtaining a teleportation device, and partnering with the time-traveling mutant Cable.

Deadpool would then go on to take prominent parts in various events in the Marvel universe, including the Skrulls' Secret Invasion, the Dark Reign, and assisting Cable in saving the baby Hope during the Second Coming.

Deadpool has also formed a Deadpool Corps with alternate reality versions of himself, and become a gamma-radiated monster known as Hulkpool.

Deadpool is well-known for his snarky one-liners, comments, and jokes, earning him the nickname "Merc with a Mouth". He also is aware that he is a character in a fictional medium (comic book, video game, etc.), often making comments on the nature of such, and sometimes interacting with elements of the medium. He is also certifiably insane.

The Merc with a Mouth...while he is incredibly silly, Deadpool is one of the most effective mercenaries out there.

Fun Facts
Poolstroke
Marvel Comics' Deadpool started out as sort of a pastiche of DC's Deathstroke the Terminator. Although Deadpool still retains both eyes, the two characters' costumes are similar, as are their names (Deathstroke is Slade Wilson and Deadpool is Wade Wilson), and professions (mercenary/assassin).

Although Deadpool has evolved into a different character personality and storywise, both companies continue to make references of the characters' similarities as inside jokes, including Deadpool using his medium-awareness to comment on it, as well as Deathstroke's Earth-3 counterpart being very similar to Deadpool in terms of personality and powers.
DPM FP (Deadpool, Motherf***er, pwns)
Deadpool's use of the Shoryuken in Marvel vs. Capcom 3 stems from him using it once in the comics.
