Jameson's latest Spiderman-catching scheme involves a genetically mutated humanoid scorpion created by a scientist named Dr. Stillwell, but the Scorpion's allegiances are fickle, the monster soon declares Jameson as his number one enemy, and Spiderman must rescue his newspaper-publishing nemesis from the beast's murderous clutches. Fortunately, the Scorpion is vulnerable to Spidey's webbing, and Spidey captures the Scorpion for police capture, not once but twice, after the Scorpion escapes prison and attempts again to kill Jameson.
