Everybody holds up Stan Lee's villains (co-created with various combinations of Ditko, Romita, and John Buscema) as the ne plus ultra of Spider-foes, but his successor (barring a couple issues of Roy Thomas) certainly made some long-lasting contributions to Spider-Man's rogues gallery, as well. So, starting from Conway's first run as Spider-scripter, from Amazing Spider-Man #111 to #149 (plus some issues of Marvel Team-Up), what's your favorite Gerry Conway villain?
Hammerhead - left dying in an alley, this two-bit hood gained a steel skull and an appreciation for old-timey villainy!
Jonas Harrow - this back-alley super-surgeon is the man behind villains like Hammerhead, Kangaroo, and...uh, Megawatt?
Man-Wolf - thanks to a magic space-rock, J. Jonah Jameson's astronaut son John became a lethal lycanthrope!
Jackal - lovelorn biology professor Miles Warren perfected human cloning in his basement, so he started dressing up like an animal and fighting Spider-Man!
Tarantula - Delvadian mercenary Anton Rodriquez deals death via his poison-tipped pointy shoes!
Green Goblin - Harry Osborn took up his fallen father's mantle to battle his own best friend!
Mindworm - William Turner's mutant nature made him a psychic parasite!
Grizzly - disgraced pro wrestler Max Markham turned to crime wearing a mechanical bearskin rug!
Cyclone - disgruntled NATO engineer Andre Gerard used his wind-manipulating technology to move up in the ranks of the Maggia!
Man-Killer - her body broken by a careless man, Katrina van Horn swore revenge on all males!
Other - any big Clifton Shallot fans?
(I'll split out his villains from his second Spider-Man stint into a second poll, so hold on, Knight and Fogg fans.)
