In Deadpool Merc with a Mouth, Earth 616 Deadpool and Headpool stumbled into this universe and they met The Deadpool Kid. Earth 616 Deadpool had had enough of the Deadpool Kid and just shot him in the head. After that, Earth 616 Deadpool and Headpool left that universe. After Deadpool 616 killed Deadpool Kid that reality’s version of Nick Fury and Wolverine had little to no reaction to Deadpool Kid’s death. In fact they both said “Work’s for Me” at the same time.
He apparently survived the shot to the head and was later seen recruited by Dreadpool to root out the remaining members of the Deadpool Corps.
