Gold is a member of the Metal Men, amazing automations invented by the brilliant roboticist Professor Will Magnus. Each Metal Man is equipped with Magnus's most famous invention, the Responsometer, which gives each Metal a highly individualized personality and allows them to change shape according to the properties of the metal they represent. Gold serves as field leader of the team, supervising their individual efforts when they're in the field , or overseeing their combination into larger constructs.
