History Mac Donald Gargan was a private investigator hired by J. Jonah Jameson to follow Peter Parker in hopes of learning how he got such great pictures of Spiderman. When Jameson asked Gargan to undergo a neogenic's treatment which would give him to powers of the scorpion so he could defeat Spiderman. He agreed. So, with a special suit and a cybernetically-controlled tail, he went after Spider-Man. The treatments which transformed him proved to cause a psychotic breakdown, so Gargan was unable to tell right from wrong. He became a vicious criminal called the Scorpion. So he has devoted his life to destroy Spiderman and get his revenge on J. Jonah Jameson.
