Saint Perez Mental Asylum for the Criminally Insane is a psychiatric facility located on Earth Two.
After he was arrested for 23 counts of murder, Hunter Zolomon was sent to the mental asylum, where he received daily electroshock therapy in the hopes of fading his homicidal urges. However, one night during one of these sessions, after the explosion of S.T.A.R. Labs' particle accelerator, a surge of dark matter swept through the room, knocking everyone over and giving Hunter super speed, allowing him to escape.
