YMMV / Gotham S1 E5 "Viper"

• Magnificent Bastard: Stan Potolsky is a talented biochemist and a former employee of WellZyn, a subsidiary of Wayne Enterprises dedicated to pharmaceuticals, with Potolsky involved in the development of a Super Serum called Viper. Disapproving of the unethical research, Potolsky went to Thomas Wayne who shut down the project, only to have it reopen after the Wayne murders. Potolsky quit his job and sought to expose the truth about WellZyn to the public by handing out vials of Viper to homeless junkies. But after WellZyn's lawyer covered their illegal activities up, Potolsky decided to target the Wayne Enterprises board members for assassination, while also recruiting his old college professor to stall any cops predicted to visit. Disguising himself as a waiter, Potolsky infiltrated a Wayne Enterprises charity event and rigged the ventilation to a tank of Viper. Revealing the truth via a video message, Potolsky is seconds away from gassing the board members, before taking his own life content he has exposed the truth.
