At the end of the issue we are treated to information that Peter is not privy to, Aunt May is getting faint and dizzy!

Amazing Spider-Man #20 "SPIDEY BATTLES SCORPEY" (January, 1965)

Synopsis

JJJ has finally hit on a great plan to destroy Spider-Man. With the help of Dr. Farley Stillwell, he plans to artificially give a thug the powers of a scorpion! As an aside, the guy who's been tailing Peter was Mac Gargan. JJJ hired him to find out how Peter gets those amazing pictures, but instead wants him to be his guinea pig. 

The Scorpion is born! (Dr. Farley Stillwell also had a cybernetic costume complete with tail sitting around) He tackles Spidey and beats him heartily. Before Spider-Man can go for round two though, Stillwell realizes that Gargan's "evil nature" will take over unless he can concoct an antidote for the treatment which made the Scorpion. Ultimately, Stillwell dies, Scorpey is defeated and everything is the same...

Notes

• The Scorpion can use his fingers as "pincers" to cut through Spider-Man's webbing, but he can also just punch with them as a fist...it is unclear how he does this
• In the above picture...where the heck are they?!
