Fictional character biography

Sapphire Stagg meets and falls in love with one of Stagg's former employees, Rex Mason, and remains with him when he is transformed into the superhero Metamorpho.^[2] Simon Stagg disapproves of Sapphire's devotion to Mason and schemes to break them apart (usually by putting Metamorpho into harm's way).^[3] Sapphire and Rex eventually marry and have a son named Joey. Joey inherits the transmutation abilities of his father, but can affect the chemical properties of other objects as well.^[4]

For a time, Sapphire believes that Metamorpho has died, and Simon arranges for her to marry his Neanderthal assistant Java.^[5] Although she remains loyal to Java, her heart always belongs to Rex. Sapphire later discovers that Metamorpho is alive and working in Paris as a member of Justice League Europe. The two have since reunited.

Birds of Prey

Java comes upon Black Canary while searching for help for Sapphire. He states Sapphire and Joey, Metamorpho's son, has been caught in a lab explosion and merged into a single energy being who was taking revenge upon Simon Stagg's former colleagues. It is revealed that not only were Sapphire and Joey merged, but so was Simon. It is he who is directing the revenge. Black Canary realizes that Java is actually Metamorpho, somehow affected to believe he is Java. The three are separated once more; Simon claims to have been overcome by the energy itself and unable to control his actions.^[6]
