The Spectacular Spider-Man #72

Peter Parker finds himself in a swirling, churning vortex of webbing and water on Ed Hannigan's striking cover, with a blue-suited figure at the center of the chaos and a sleek robotic form diving from above — all tension and kinetic energy as the tagline promises a confrontation with the notorious Doctor Octopus. Bill Mantlo scripts and Hannigan joins Al Milgrom and Rick Magyar on interior art for this November 1982 issue, with colors by Glynis Wein giving the watery mayhem a vivid, almost dreamlike quality. If you're following Spider-Man's rogues' gallery through the early '80s, this one's hard to pass up.
