 His first act of super-villainy has him using his abilities to manipulate his appearance and taking the name "Doctor Destiny", Dee kills Penny before trapping most of the Justice League in their worst nightmares. However, Martian Manhunter rescues his fellow Leaguers while a sleep-deprived Batman eventually tracks down Destiny and confronts him. In the ensuing struggle, Destiny accidentally injects himself with a powerful sedative and is later re-incarcerated at Stryker's in a catatonic state humming Frere Jacques over and over again.
