John Deleon
John Deleon was a corrupt businessman who operated out of Star City. Deleon framed Queen Industries CEO, Oliver Queen, for mis-using public funds, which ultimately resulted in Queen losing his company, as well as his family fortune. Deleon later entered into a business deal with the Hellgrammite, who was operating a front company called Rebirth, Inc., that could reputedly de-age paying customers. Deleon got cold feet however when he learned that the villain's process was less than reliable and turned against him. Knowing that his life was in danger, Deleon sought aide from Oliver Queen (believing him to actually be Batman). Deleon stole a quantity of money, which he intended on using to pay off the Hellgrammite to leave him alone. The Hellgrammite lunged at him and John Deleon died of fright.
