Morgan Michaels (Earth-4678)

Doctor Morgan Michaels was a specialist in hereditary genetic diseases. He was hired by Oscorp Industries to lead and perfect the GR-27, a serum created to serve as a cure for many incurable genetic diseases. When the first tests proved disastrous and the GR-27 was deemed dangerous to the populace, the only sample of the serum (which gained the nickname "Devil's Breath" from the lab technicians) was entrusted to Michaels, who kept it with himself on a briefcase at all times.
