Rex Mason was a security guard at Stagg Industries who was in love with Sapphire Stagg, the owner's daughter. After being trapped in a chamber and gassed with chemicals by Simon Stagg, Rex mutated into Metamorpho.
In "Toxic", Rex Mason wanted to marry Simon Stagg's daughter, Sapphire. On the surface Simon pretended to be happy for them but in reality he was furious and tricked Mason into getting trapped in Project Metamorpho and gassed him, mutating Rex into Metamorpho.
Batman and Barbara Gordon (Oracle) later hacked in to the Stagg Industries security footage and retrieved the video of Simon taking off his mask after mutating Rex. Rex then allied himself with Batman, and helped whenever they crossed paths.
