The Flash: 6 Comic Book Villains That Haven't Appeared On TV Yet

The Flash The CW

After six seasons on television, The Flash has put a spotlight on many DC villains that comic book readers may have otherwise never seen in live-action. This includes the obvious folks like Captain Cold, but also far more obscure names, like Mirror Master or Weather Wizard. While the latter two have been notable foes of The Flash for years, it's understandable if Hollywood just didn't see either having the appeal to justify appearing in a massive Hollywood movie.

Luckily, these type of villains thrive on The Flash, and the kookiest of villains have been in some of The CW series' most memorable episodes. Fortunately, there's still plenty for the show to introduce, so hopefully future seasons will bring some of these other infamous comic book villains to live-action.

Cobalt Blue DC Comics

Cobalt Blue

In one of the most bizarre villain origins in The Flash's history, Cobalt Blue is the twin of Barry Allen. The twin is born to the Allens, but is given to the Thawne family (yes, that Thawne family) by the doctor who accidentally killed their child. The Allens are told Barry's brother was a still birth, and the now-Thawne child was raised evil. He eventually inherits the family power of the "blue flame," which allowed him to steal the speed of speedsters.

Cobalt Blue is certainly a villain worthy of "big bad" territory, and his appearance after "Crisis On Infinite Earths" in DC Comics means The Flash could be gearing up to use him as well. Granted, it would take some real work to work back through the show's established lore of Barry's birth and all that. Still, if The Flash could pull a Cobalt Blue story arc off, it would certainly put it in contention for one of the best superhero shows of all time.

Star Sapphire DC Comics

Star Sapphire (Golden Age)

While the Star Sapphire has become more of a mantle and a group associated with the world of Green Lantern, the character was first introduced as a Flash opponent. The Golden Age Star Sapphire claimed to be the queen of the 7th dimension and sought out to exterminate all plant life from Earth. DC comic books later tweaked this villain's origin and made her a former queen banished to the 7th dimension, thus no longer officially connected to the Zamarons' Star Sapphire.

Queen or not, I'd love to see this villainess on The Flash if only to tie into the upcoming Green Lantern series in development at HBO Max. A minor villain of the week role would be ideal for some form of crossover, similar to how Arrow introduced Barry Allen before officially kicking off The Flash. We need Green Lanterns in the Arrow-verse, and this feels like a feasible way to make that happen.

Manfred Mota

Manfred Mota

Manfred Mota is one of the few villains in DC comic book history to take on several new personas throughout the Flash's history. He was known by Atom Smasher in Jay Garrick's era, Professor Fallout with Barry Allen, Fusionn with Wally West, and his namesake under John Fox. That's a lot of re-branding for the run-of-the-mill villain, especially when his real name is badass enough to stand on its own!

Manfred Mota would give The Flash an opportunity it hasn't really utilized yet, which is telling a story that follows multiple speedsters in multiple time periods. Doing Mota would cover a lot of ground, but it's hard to dispute The Flash couldn't do it with its large episode counts. The only real issue with the plot would be that the series has muddled up the timeline and origins of its main speedsters, so a good deal of this arc would need to be re-adapted to fit The Flash universe.

Red Death DC Comics

Red Death

Red Death is a Bruce Wayne from an alternate reality who subdues and forcibly fuses himself with Barry Allen in order to obtain the powers of the Speed Force. The method allows him to quickly kill most of his Earth's Rogues, though his efforts fail to save his world from destruction. Red Death then accepts an invitation from The Batman Who Laughs, who gives him a chance to join other Batmen of failed Earths in a plot to overtake the regular multiverse.

Red Death was mentioned on The Flash last season, but there's still some question on whether he'll actually ever appear on the show. The Dark Nights: Metal story is pretty dense, especially for a shared universe that will introduce Bruce Wayne for the first time during "Crisis On Infinite Earths." Of course, the Arrow-verse could do its own take on the character and perhaps combine him with a different established character. Did someone say Oliver Queen? I thought I heard someone say Oliver Queen.

Daniel West The Flash DC Comics

Reverse-Flash (Daniel West)

Daniel West was the younger brother or Iris West in the New 52 continuity, and not nearly as upstanding of a citizen as his sister. That much could be gathered from the fact that he eventually took up the mantle of Reverse-Flash. He basically has the same abilities as Eobard Thawne, though he's a little more redeemable than Thawne.

Daniel West's existence is somewhat complicated by The Flash's current lore. Wally is Iris' long-lost brother, and Barry would've known about another child raised in their home as he lived there. With that said, The Flash has influenced the events of the past and made permanent changes before. So could it retcon Wally for Daniel? Should the series ever kill off Eobard Thawne, this would be an option for replacing him!

The Flash DC Comics

Steve Palmer

Actor Steve Palmer had been cast to play The Flash in a big movie, and the actual Flash was his stunt double. When incidents during filming make it apparent someone is targeting Palmer, Barry poses as fake Flash in order to stop the criminal responsible. It turns out Palmer was behind it all along, and this was all one big budget scheme to kill The Flash and live off his name as a brand ambassador. The Scarlet Speedster stops him, but unfortunately took out the leading man in his movie.

Steve Palmer would be the perfect subject for a classic and kooky throwaway episode of The Flash. Plus, it would be hilarious for The CW series to cover the superhero movie wave, and how it would play out in a world that features actual heroes. How would Barry react to the news that an actual movie about him has had trouble happening when compared to other heroes?
