Fact: The name ‘Deadpool’ is based off a rejected experiments program.
The back story of the character Deadpool is pretty vague just like the person who plays the supervillain. The character believes himself to be Wade Wilson, but is subject to speculation due to his inability to remember his personal history, due to a mental condition. The character is terribly disfigured and is a mentally unstable mercenary with accelerated healing factors.
Deadpool’s strengths come from his ability to heal himself quickly. Additionally, he is among just a few Marvel characters that break through “the 4th Wall.” Meaning, he knows that he is a fictional comic book character. Also, he is known as “Merc with a Mouth” because of his talkative nature and tendency to break that fourth wall. He was a failed Weapon X experiment that was sent to a workshop hospice for failed experiments. There him and other inmates would wage bets on who would die next, hence was known as ‘Deadpool’(Clearer explanation below).
In 2009, the character makes his first film debut being played by Ryan Reynolds in X-Men Origins: Wolverine. By 2014, with the help of comic book fans, the film becomes a reality and is set to air February 12, 2016. On April Fool’s Day 2015, Ryan Reynolds posted that the movie would be rated PG-13 on Twitter, which prompted a massive backlash, to which, later that day would confirm the film would be posted as rated R.
Other Deadpool Tidbits:
The creator of the character is writer Fabian Nicieza and artist/writer Rob Liefeld (Came up with Visual Design and Name). Deadpool’s first appearance is The New Mutants #98 and was created in 1991.
Deadpool has been implanted with several different types of memories in order to block out his prior missions given to him during his time in the Weapon-X program, which led him to insanity. As time has gone on, his memory has become better with the help of Cable and Dr. Strange, whom have removed a lot of the junk.
