Dr. Wallace “Wally” Moseley is an attending doctor at St. Bartholomew’s Hospital in Vanity City. While working there, he became friends with Dr. Curt Falconer, the secret identity of the hero known as Aztek. Moseley was one of the first doctors to befriend Aztek, and even set Aztek up on a date with nurse Joy Page.
Moseley works under St. Bartholomew's supervisor Julia Frostick. While Dr. Moseley is a consummate ladies-man, he is also a skilled surgeon.
