Spider-Man and the Human Torch have always had a love-hate relationship so when Johnny invites himself into Peter’s apartment, you don’t need a spider-sense to know there’s going to be trouble.
FF #17 opens with Peter making mental to do lists. One list for Peter Parker. One list for Spider-Man. And one list for Peter Parker & Spider-Man, which has one item: “Kick out Johnny Storm.”
Johnny’s antics causes “kick” to become “kill” and eventually “#^&$@&!!.” He turns the closet into a portal to the Negative Zone, calls Peter at work to ask him to bring home drinks, and throws a wild party with superpowered aliens, which actually turns out to be fun. Peter reconsiders letting Johnny stay until he opens the bathroom door and finds Annihilus, Lord of the Negative Zone, taking a dump.
