3) Mirror Master
The Mirror Master moniker has been taken on by four characters over the years, the most notable of which are Samuel Joseph Scudder (the current New 52 version) and Evan McCulloch.
Scudder is a simple convict who stumbles upon a hall of mirrors, and experiments until he finds a way into his own reflection. He develops a strong power over mirrors, and is then able to travel through them and trap others inside of them. He has a taste for the fantastical, often uses invisibility, hypnotism, and holograms against the Flash, and can even use mirrors to travel into other dimensions and parallel universes.
McCulloch, one the other hand, is an orphaned Scottish mercenary; he traveled the world in search of his birth parents and became one of the world’s most renowned assassins in the process. Eventually, he’s picked up by the U.S. government and given Scudder’s costume and weapons, in exchange for his efforts in taking down other super-powered beings.
Either version could easily make their way to The Flash, though someone like Scudder makes more sense at first. However, Arrow‘s already established the Suicide Squad, which could easily explain McCulloch’s existence, so perhaps we could see an amalgam of the two. Either way, it’s only inevitable that we’ll see one of the Flash’s most iconic and beloved foes.
