The Flash Season 4 Villain

“Next season we’re not going to have a speedster as the main bad guy,” executive producer Andrew Kreisberg told the crowd at Paley Fest in Los Angeles. 

That’s something of a relief. While, of course, season one’s Eobard Thawne, the Reverse-Flash was kind of the gold standard of speedster big bads, Zoom was a little more of a mixed bag during season two. The Savitar storyline continued to unfold during season three, but it’s nice to see that they’re looking to explore other options next year.

So who could that other, non-speedster villain be? Well, in one key episode, we got a major clue from a minor villain. As Abra Kadabra was being led off to face his fate, Barry tried to appeal to his better nature, begging for information about Savitar. While pointing out that nobody hurt Barry as badly as Savitar will, Kadabra rattled off the names of the villains who have most impacted Barry’s life, including Thawne and Zoom. But there was another name.

“Devoe.”

Devoe’s name was mentioned again in the season finale, this time by Savitar.

There’s only one Devoe worth mentioning in Flash mythology, and that’s Clifford Devoe, the Thinker. Devoe is traditionally known as more of a Jay Garrick villain, first appearing in All-Flash Comics #12 way back in 1943. He took on both Jay Garrick and the Justice Society numerous times, and he had a quaint (by modern standards) “thinking cap” which allowed him some amplified psionic abilities. But when his physical body died, he became a non-living artificial intelligence with even greater power. 

There are some more details on The Thinker here:

So that takes care of the non-speedster big baddie. But one other villain comes to mind, the problem is, he’s a speedster.

That speed force storm we saw at the end of the episode resembled events from recent Flash comics, and that’s what gave birth to the villainous Godspeed. Something tells me they’ll wait a while before exploring this further, though.

One other thing has been teased a couple of times for later seasons, and it’s the kind of storyline that only makes sense for the latter seasons of a show like this one. I wrote a little bit more about that here, but there are major potential spoilers involved, so go there at your own risk. I suspect this is more of a season five thing, though.

The Flash Season 4 Cast

Sugar Lyn Beard will play Rebecca Sharpe, known as Hazard, who will appear in the third episode of season 4. Variety describes Hazard as “perpetually down-on her luck and is convinced her life is cursed — until a freak accident changes everything. With the universe on her side, she poses a threat to both Team Flash and Central City.”

Hartley Sawyer has been cast as Ralph Dibny. Who is Ralph Dibny? He’s the Elongated Man, of course! Who’s the Elongated Man? He’s DC’s stretchy superhero! No, not Plastic Man, the other one.

Here’s the official word from DC:

Described as one of the Flash’s most iconic allies, Ralph Dibny—a.k.a. The Elongated Man—is a fast-talking private investigator with investigative skills that rival those of Batman. Upon discovering he has the power to stretch his body to any shape or form, Dibny uses his new abilities to help Team Flash solve one of Central City’s greatest mysteries.

Mr. Sawyer sure looks like Ralph Dibny, too…

We got some other casting news last week during The Flash SDCC panel:

Danny Trejo (Machete) is set to join the cast as Breacher, a bounty hunter and father of Gypsy (Jessica Camacho).

Neil Sandilands (The 100) is The Thinker, a metahuman who battles The Flash throughout the season. He is billed as the “fastest mind alive” and plans to fix what he believes to be wrong with humanity. We have more details on The Thinker down below.

Kim Engelbrecht (Dominion) plays The Mechanic, an engineer who creates devices for The Thinker. She is the villain’s right hand. 

Katee Sackhoff has joined The Flash Season 4 for a recurring role as the DC Comics villain Amunet Black, reports EW. The character will debut in Episode 5, titled “Girls Night Out,” in a role that will apparently be the centerpiece of a mini-crossover with Arrow, enlisting the help Emily Bett Rickards’s Felicity Smoak.

Amunet, a.k.a the Blacksmith, is known in DC Comics for gaining the power to manipulate metal, even merging it with her own flesh. However, she’s also a schemer extraordinaire who’s been married to the likes of rogues gallery members such as Hunter Zolomon (Zoom) and Goldface. She would eventually build a criminal network for herself, masterminding metahuman criminal endeavors that often collide with the Flash.

Sackhoff is considered geek royalty for her 2004-2009 run as Kara Starbuck on Syfy’s Battlestar Galactica. She had TV runs on Nip/Tuck and 24 and roles in films such as the 2013 horror film Oculus and the 2013 Vin Diesel franchise revival Riddick. She’s also been a standout on the A&E-cancelled/Netflix-acquired modern western cop show Longmire, on which she will return in the upcoming sixth season. However, she’s put in time as a villain before, notably on NBC’s short-lived 2007 Bionic Woman reboot as the evil bionic prototype enemy of Michelle Ryan’s Jaime Sommers.
