The following is a list of former championships in Full Metal Wrestling (FMW), as of December 13, 2018. There are three inactive championships.
The first inactive title is the PWA Women's Championship, which was competed on the Schizophrenia brand between the promotion's female e-wrestlers when FMW was known as the Psychotic Wrestling Alliance (PWA). The title has never been active since the PWA changed its name to FMW.
The other two inactive titles are the FMW World Tag Team Championship and FMW United States Tag Team Championship. During the PWA brand extension, the PWA World Tag Team Championship as it was called then, was brought to the Pyromania brand (which now is Inferno). Without a tag team title, Schizophrenia (now known as Insanity) commissioned the PWA United States Tag Team Championship shortly thereafter. On September 6, 2008, the titles were unified to form the FMW Undisputed World Tag Team Championship when the MWA defeated the Dark Brotherhood at Altered Reality IV.
