Samuel Joseph Scudder is a simple convict, but has the goal to learn how to get inside the reflection of a mirror. Stumbling into a hall of mirrors, he experiments and discovers a way to get in his own reflection. He uses this power to become the criminal Mirror Master, and is a frequent foe of the Flash. Scudder dies around the same time as Barry Allen, alongside the Icicle during the "Crisis on Infinite Earths". Later, Captain Boomerang briefly assumes Scudder's identity, becoming the second Mirror Master. He uses this as an alternate identity with which to commit crimes, thus not alerting his teammates in the Suicide Squad to his extracurricular activities. Pre-"Crisis", he studies mirrors after someone's reflection is held inside a mirror he was working on in the prison workshop. He then learns how to create creatures of light.
