Since the day The Flash premiered on The CW, fans have been rejoicing with every new addition to the Silver Age Rogues Gallery: Captain Cold (Wentworth Miller), Heat Wave (Dominic Purcell), Pied Piper (Andy Mientus), Weather Wizard (Liam McIntyre), the Trickster (Mark Hamill and Devon Graye), and Captain Boomerang (Nick Tarabay). Today, another member joins the notorious super villain group as Comic Book Resources reports that Aquarius actor Grey Damon has been cast as the one and only Sam Scudder, aka Mirror Master.

The cast and fans have not been shy about letting producers know how anxious they were to see him on the show. Actor Carlos Valdes (Cisco Ramon) even said at MegaCon in May that “with [VFX supervisor] Armen [Kevorkian]’s visual effects skills, some magic could be done with Mirror Master” and that he’d like to see “a multi-episode arc” with the character.

While we don’t know about a multi-episode arc with Scudder, we do know that he’ll be appearing in the fourth episode of Season 3. Here’s Warner Bros. Television’s official description of the character: “One of the Flash’s most infamous Rogues, Sam Scudder — aka Mirror Master — is a smooth criminal with a huge ego. Upon discovering he now has the power to travel through any reflective surface, Scudder embarks on a massive crime spree to prove himself the greatest thief that Central City has ever seen.”

Arrowverse Crossover: "Crisis on Earth X"

Scudder, the first incarnation of Mirror Master, originally appeared in The Flash #105 all the way back in 1959 and was created by John Broome and Carmine Infantino. Whereas it looks like The Flash is making him a metahuman, Scudder has never had powers in the comics and has relied solely on his trick mirrors to outsmart the Flash. However, in The New 52, after being caught in an explosion that was meant to fuse the Rogues with their individual weapons, Scudder became permanently caught in the Mirror World.

Earlier today, YouTube channel That Hashtag Show released a video revealing three different casting announcements for The Flash‘s third season–one of whom is Scudder.

The second one is another prominent member of the Rogues Gallery, famously known for being the boyfriend of Lisa Snart (Peyton List), aka Golden Glider. However, it looks like the show will be doing their own “spin” on the character:

ROSALIND “ROSA” DILLON – Female, late 20s, open ethnicity. There’s crazy and then there’s crazy… and then there’s Rosa. A wild-eyed whirlwind of a woman, this vexing, unpredictable, mentally unstable criminal has a history of violence and a nasty habit of turning people’s worlds upside down. Open to offer only / cameo ideas as well. RECURRING GUEST STAR.

Based on this description, it seems as if we’ll be meeting the female version of Roscoe Dillon, aka The Top. This won’t be the first time The Flash has genderbent a character, as roboticist Brie Larvan (Emily Kinney), aka Bug-Eyed Bandit, was their own take on the comic version of the super-villain, Bertram Larvan.

The third and final casting description is not as easily identifiable, but certainly contains a good number of clues to figure out who it might be:

FRANCIS – Female, 18 or older to play 17, open ethnicity, bright, a good kid, kicked around from foster home to foster home, Francis is now with an abusive foster father, John James, and his submissive wife, Karen. Sick and tired of being hurt, Francis has been having blackouts during which time she becomes her alter-ego, a meta human, who has superhuman strength and a desire for revenge….POSSIBLY RECURRING GUEST STAR (12) Shooting this month

That Hashtag Show has theorized that this is one of either two possible comic book characters: Frances Kane, aka Magenta, who has a history with our new Kid Flash, Wally West (Keiynan Lonsdale), or Rhosyn “Rose” Forrest and her alter-ego, Thorn.

Either way, it looks like the character has been cast and has already been on set filming:

You may know Joey King from movies such as Ramona and Beezus and Oz the Great and Powerful. This is all still speculation, but based on age and visual similarities to either of the described characters, it would be surprising if this wasn’t the role she was playing.
