Brolin's character, also known as Nathan Summers, has been pared up with "Deadpool" in many of the comics, including their own series. As a child, he was sent to the future where he became a warrior, and eventually came back to present day. His appearance in the film was teased in the "Deadpool" scene before the "Logan" film, where a message on a phone booth read, "Nathan Summers cumming [yes, that's the correct spelling] soon!"
"Deadpool" had a hugely successful box office, earning over $782 million worldwide, and became the highest-grossing R-rated film in history.
