The person who is telling the story is often called the narrator. It could be the main character in a first - person narrative, sharing their own experiences directly. For example, in 'The Catcher in the Rye', Holden Caulfield is the narrator, and we see the story unfold through his eyes.
We can learn about the events that are taking place in the story. The narrator will describe what is happening, who is involved, and where it is all going on.
Deadpool became Deadpool through a series of complex and sometimes convoluted events in the comics. He was originally a mercenary named Wade Wilson, who underwent experimental treatments that gave him his unique powers and personality.
There is a loose link. The version of Deadpool in Wolverine Origins provided a starting point, but the standalone Deadpool movies developed his character and story in a more distinct and expanded way, deviating from the initial portrayal to create a more focused and engaging narrative.
It's a bit of a mixed bag. While there's a link, the portrayal of Deadpool in Wolverine Origins doesn't fully align with his later, more developed storyline. Some elements were changed or not fully explored.
Obviously, the main characters are the two Deadpools. They are both versions of the same character but with potentially different backstories and personalities in this graphic novel.
