The Scorpion, A Little History
Did you know that J. Jonah Jameson, the mortal enemy of Spider-Man actually created The Scorpion? Let me explain.
Mac Gargan was a private investigator who had been hired by J. Jonah Jameson to find out why Peter Parker was always around to take the best photos of Spider-Man. Jameson had a theory that Peter Parker was able to take good photos of Spider-Man because the two were connected. After attempting to solve the mystery and coming up empty-handed, Jameson paid Gargan to undergo an experiment. The experiment would imbue Gargan with super strength, durability, etc and allow him to battle Spider-Man on an equal level. Ironically, the experiment turned Gargan into a natural enemy of a real spider, a scorpion. Conveniently, this is what he would call himself.
With his new powers in tow, The Scorpion sought out to destroy Spider-Man. He even accomplished victory during their first two encounters. This, of course, thrilled Jameson. Unfortunately, because of the experiment, Gargan was actually losing grip on reality. In effect, he was losing his mind.
Realizing what was happening, Gargan sought revenge against the man who caused this pain, Jameson. Luckily, just before he could exact his revenge, Spider-Man showed up and saved the proverbial day.
