History
Cable and Deadpool decided to travel back in time to 2016 AD and confront Stryfe. Unfortunately, it was a trap and Stryfe unleashed dinosaurs and vampires onto New York City. The U.S. Air Force ended up dropping a nuclear bomb on the city. Cable was able to open a portal to 2017 AD and warned his past counterpart not to do the time jump. The explosion killed Nathan; his corpse landed in the future and past Deadpool disposed of the body.[1]
