First appearance of The Scorpion. So many classic villains in these early issues….
Mac Gargan is a thug hired by J. Jonah Jameson to spy on Peter Parker and see how he gets all those great Spider-Man pics. When JJJ learns about Dr. Sitwell’s ability to give people super-powers, he puts Gargan in the mix and Scorpion is born. Yodda yodda. It’s a fine origin tale, but the real story is on the splash page, where the creative tension between Steve and Stan is bleeding into content.
