Dr. David Wheeler was an unscrupulous child psychologist who ran a therapy ranch for troubled kids.
In consequence of the new stern parental liability laws, Dr. Wheeler established a clinic that offered desperate parents the solution to handle their rebellious children. In exchange of a considerable sum, Dr. Wheeler promised the finest long term counseling for adolescents. However, in secret, Wheeler was a cruel and unforgiving sadist whose therapy consisted of brainwashing techniques, accomplished by means of sleep deprivation and endless belittlement. He attempted to break his patients' spirits, turning them into drones. The ranch was located outside the premises of Gotham City, and worked as a true prisoner camp. There were several guards with leverage and artillery to keep the inmates in check. For those who would get out of line, Wheeler confined them in ISO.
The influx of inmates to the ranch was massive. All kinds of teenagers were admitted to the clinic ― from the most rebellious to the mildly disobedient ones. Upon this, Terry McGinnis set off to investigate. When Dr. Wheeler found Sean picking a fight with Terry, he sent the former off to ISO before searching Terry, finding a small camera on him containing incriminating evidence. Dr. Wheeler apprehended Terry overnight and planned to do away with him, in case someone went looking for him.
Thanks to the combined efforts of Terry and Sean, a mutiny ensued and the ranch was shut down. Wheeler was captured by Sean, a patient out for revenge who dropped him off the roof. However, Batman lunged at him and saved his life. Dr. Wheeler was subsequently arrested on charges of abuse and torture.
