Simon Stagg was the co-founder, alongside his business partner Dr. Alex Sartorius, and CEO of Stagg Enterprises, a pharmaceutical company that was predominately stationed in Central City. While Stagg displayed an ethical image and a company that worked to create vaccines to cure certain ailments and diseases, his true face was one of a deprived sociopath, who used hundreds of volunteer and abducted human test subjects, many of whom horrifically perished during trial periods, including Dr. Sartorius, to further research on biological weapons to be sold to the military, including armed forces that were in conflict with the United States.
