"Hammerhead is Out!" Part 2 of 3. Script by Len Wein. Pencils by Ross Andru. Inks by Mike Esposito. Cover by Ross Andru and Frank Giacoia. After surviving his free fall from the helicopter, the wondrous wall-crawler continues his pursuit of Dr. Octopus and Aunt May! The six-armed super-villain takes refuge at Brookhaven National Laboratory to draw Hammerhead's ghost into a deadly trap! But the sudden arrival of the web-slinger throws off Doc Ock's plan! Instead of destroying the ghost, Octopus' equipment returns Hammerhead to flesh and blood! And that sets the stage for the next issue's three-sided tussle: Doctor Octopus vs. Hammerhead vs. your friendly neighborhood Spider-Man! Cameo appearances by Mary Jane Watson, Glory Grant, Joe Robertson, and J. Jonah Jameson. (Notes: This issue contains a full-page ad for Hostess Twinkies featuring Captain America vs. the Red Skull.
