“By My Powers Shall I Be Vanquished!”
Writer: Denny O’Neil
Artist: John Romita Jr.
The gun that Wizard shot at them transferred Spider-Man’s spider sense into Sub-Mariner’s head, trying drive Sub-Mariner crazy and such. Spider-Man and Sub-Mariner go to the Fantastic Four and get Reed Richards to switch everything back to normal. It works. Spider-Man goes looking for that hot new neighbor he likes so much. Somehow still doesn’t realize she’s that evil enemy of Sub-Mariner. Then she tries to kill Spider-Man and changes into her evil-looking form. Sub-Mariner comes in, knocks her out, then takes her back to Atlantis for proper justice.
