The Spectacular Spider-Man #143 (1988)
“Deadline in Dallas”
Writer: Gerry Conway
Artist: Sal Buscema
Punisher goes to Dallas with Persuader and another Kingpin goon to kill two drug dealers called the Lobos brothers. Spider-Man has been trying to look for Punisher, he sees he’s in Dallas and goes there to find him. When Spidey finds him, they fight, and then when Persuader tries to make Punisher kill Spider-Man, Punisher instead kills the goon and then Persuader. He says he was never fully under his spell. Killing drug dealers is something he would’ve done anyway. Also, the Gwen Stacy clone from a while back is on the run from some people who are trying to kill her and is seeking the help of Peter (though she hasn’t gotten to him yet).
