Mirror Master is a villain from The Flash comics and media.
So far, there has been three criminals to hold the title of Mirror Master.
Sam Scudder was already a criminal before he gained his powers. While serving time in prison for a burglary-homicide, he was working in a prison workshop, when he accidentally created a mirror that could hold an image for a certain amount of time. After this, he escaped from prison and created numerous mirror gadgets to help with his crime sprees. Calling himself the Mirror Master, Scudder terrorized Central City for years, either on his own, or as a member of the Rogues, only to be foiled by the Flash (who's civilian identity, Barry Allen, was ironically responsible his incarceration in the first place). Scudder was killed during the Crisis on Infinite Earths.
For a brief period of time, Scudder's fellow rouge Digger Harkness/Captain Boomerang used the Mirror Master alias and gear to commit crimes while on the Suicide Squad. Harkness soon quit using the Mirror Master alias after being caught and handed to Amanda Waller, who then tricked him into a fake assault scene where he was forced to constantly switch between his Mirror Master and Captain Boomerang identities.
The current Mirror Master is a Scottish mercenary and criminal named Evan McCulloch. Originally a non-powered merc, McCulloch was given Scudder's costume and equipment by a consortium of the US government. Though he first targeted the superhero Animal Man, McCulloch eventually turned his attentions to the then current Flash, Wally West, and has been a thorn in his side since.
