Over the past three seasons of The Flash, Barry Allen has faced a good number of DC Comics villains. Though each season to date has seen the Fastest Man Alive try to take on a big bad speedster, his and his friends’ misadventures along the way have seen Team Flash face a number of comic book rogues. And though some have been left in the dust by the ever-growing Arrowverse, a good number still remain that could pop up and vex our hero.
Despite Central City’s overflowing evil meta population, season 4 of the series will certainly introduce us to some new foes for Barry. We know that the big bad will not be a speedster for once, leaving a number of other Rogues from the comics the chance to step up to the plate. Along the way, plenty of other metas and super-criminals will likely cause trouble for the Flash and his partners, and the show has no shortage of source material to pull from.
While the series has given us a few hints as to who could be on their way, there’s still plenty of villains from the page we hope will show up this coming season on The Flash.
Here are 15 Rogues We Want To See In The Flash Season 4.
15. Folded Man
In an effort to move away from speedster villains, The Flash still needs to ensure it pits some worthy foes against the Fastest Man Alive. In the past, the show has had to stretch when it comes to certain Rogues and their ability to effectively threaten the Flash. That’s where the Folded Man comes in.
Born Edwin Gauss, the Folded Man first appeared in 1999’s The Flash #153. One of DC’s biggest geniuses, he graduated MIT keen to finish the Unified Field Theory work Einstein had begun. By leeching some advanced tech, he was able to catapult his work into another dimension—literally. Wearing his special suit, the Folded Man can hop between dimensions at will. Essentially an evil version of Vibe or Gypsy, the Folded Man would present the Flash with a believably powerful foe without relying on more super-speed.
14. Double Down
Double Down isn’t actually new to the Arrowverse, but he would be to The Flash. Played by J.R. Bourne, Jeremy Tell appeared back in 2015 on Arrow during season 4’s "Restoration". In the comics, Tell has a form of cursed magic that allows him to pull tattooed playing cards off of his skin. From there, he can cause all sorts of damage throwing them and even partially controlling them with his mind.
While his abilities may seem silly, his cards have been able to cut Superman himself. In the Arrowverse, he’s a meta, but his powers remain the same. He first caused trouble for the Flash in 2001’s Flash: Iron Heights, so it’d make for a nice Arrowverse crossover to see Tell pop back up and face off against the Scarlet Speedster.
13. The Renegades
The great thing about the Renegades is that they’re essentially a heroic version of the Rogues from the future. Though not related to the present Rogues we’ve met, The Flash could still find a way to have fun with the casting of each.
Appearing in 2010’s Flash #1, their story revolves around the Reverse-Flash altering history so the Flash looks like a criminal. In the 25th century, a group of cops adopt identities based on the Rogues of 21st century and make it their mission to eradicate all crime. Eventually, they’re even tricked into traveling to our time in an effort to stop the Flash.
Made up of characters like Commander Cold and Mirror Monarch, the Renegades could easily fill a two-part episode involving the Flash and his team working to convince the future cops of their innocence. Now that time travel factors into the plot more, The Flash can really start pulling in more exciting arcs from the comics.
12. The Fiddler
The Fiddler is an admittedly silly villain, but his long history with the Flash in the comics means he’s bound to pop up on the show eventually. Debuting in 1948’s All-Flash #36, the Fiddler has been bothering Flashes for a long time. His origin is also classic Golden Age material.
Once a petty thief, he learns a form of musical hypnosis while in prison with an Indian mystic. Somehow creating a fiddle culled from random objects inside the prison, Isaac Bowin is able to use his new skills to escape and head to Keystone City. As the Fiddler, he’s spent decades fighting the Flash and the Justice League.
Like the far more recent Music Meister, his background could easily be revamped on the series to make him fit more in line with the Arrowverse. Then again, a little more absurdity on The Flash wouldn’t be a bad thing after the dour past season.
11. Rag Doll
Like the Fiddler, Rag Doll has spent decades causing trouble for multiple versions of the Flash. Premiering in 1942’s Flash Comics #36, Rag Doll was created by venerable comic scribe Gardner Fox.
Possessed of the extremely rare triple-jointedness, Rag Doll is a master contortionist. His body is even able to withstand incredible amounts of force, meaning the Flash’s powerful punches wouldn’t cause much damage. His circus and criminal background have also gained him skills as a thief and hypnotist.
While Rag Doll's abilities shouldn’t make him much of a match for the Flash, it could be interesting to see the off-putting rogue pop up while the Flash is still stuck in the Speed Force. Perhaps Wally could even be indisposed, allowing the other members of the team to step up and face the creepy clown-like villain.
10. Razer
Not to be confused with the character from Green Lantern: The Animated Series, Razer is a pure-90s comic villain debuting in 1993’s Flash #84. Rocking a sci-fi suit of armor, Razer’s uniform is more than just mere metal.
Composed of an experimental polymer called lubrilon, Razer is essentially a huge, bulky foe in a super-slippery costume. Add in some nasty blades and Razer has both offensive and defensive capabilities.
Razer's mixture of strength and an inability to be properly engaged with prove a tricky science problem for the Flash. Though on the sillier side, Razer would allow Flash to lean back into its campy sci-fi roots. Razer also has ties with Linda Park, Abra Kadabra, and Prometheus in the comics, giving him plenty of connections in the Arrowverse already.
9. Murmur
Like Double Down, Murmur has already appeared on Arrow. Interestingly, Murmur also premiered in Flash: Iron Heights in 2001, alongside Tell.
In the source material, he’s former surgeon Dr. Michael Amar, who loses his mind, sews his mouth shut, and becomes a deranged serial killer. In the Arrowverse, he appears to be a criminal and gang leader rather than a surgeon. Still, his creation of diamond-tipped bullets and his creepy look and demeanor make him a threat for Oliver and his team.
Like Rag Doll, Murmur would be easier for the Flash to take down. That said, having him be more of a crime boss pulling the strings of other metas could be an effective use of the character. He could also prove to be a threat to a less super-powered member of Team Flash, maybe as a target of an investigation by Joe while the rest of the team are tied up with the big bad.
8. Blacksmith
Appearing in Iron Heights alongside Double Down and Murmur, Blacksmith has yet to show up in the Arrowverse. And as one of the Flash’s few female villains, she should really make an appearance next season. Blacksmith could also easily sustain a prolonged arc, as her pre-supervillain gig would make for a great subplot.
Amunet Black starts out her career operating a black market for supervillains called the Network. Having a place where low-level thugs could buy and sell crazy tech and gear would make for a great plot that could include the superhero and police procedural sides of The Flash.
Amunet then uses the powerful elixir of villain Goldface to restructure her body and allow it to fuse with metal and inorganic material. Though no match for the Flash’s speed, it would be great to Amunet cause trouble for the team with the Network before finally stepping up later in the season as a super strong and durable villain.
7. Brother Grimm
Brother Grimm is not only a great counter to the Flash, but would allow the show to delve more into magic and the possibilities of other dimensions.
Debuting in 2000’s Flash #166, Brother Grimm exists in a King Arthur-like parallel dimension. Gifted with not only magical abilities, but the power to sense extra-dimensional energy, Grimm actually has a form of Speed Force sensing. What this boils down to is that he can predict many of the Flash’s moves.
While pitting Flash against other speedsters is one way to counter his powers, having a foe who’s not fast but able to sense what Flash will do before he does it would make for an interesting showdown. Legends of Tomorrow has found success by leaning into the more fantastical, and some of that gee-whiz flavor— along with an inventive villain— could certainly help out The Flash.
6. Spin
Debuting in 2008’s Flash #238, Spin is a villain made for today’s landscape. Known only as Mr. Auerbach, Spin is a villain by night and a fear-mongering journalist by day.
As a media titan, he uses spin to twist public perception with sensationalist news stories. Eventually, he meets a man named Edwar Martinez, who can bring out others fears and enhance their emotions. Kidnapping him and running his body through machines, Spin is able to channel Martinez’s powers and cause panic and delusions in the minds of others.
Like Rainbow Raider, this ability allows Spin to mix smarts with deception to counteract the Flash’s abilities and wreak havoc. It would also allow The Flash to wade into the waters of social commentary the way Supergirl and Agents of S.H.I.E.L.D. have been doing for their past seasons.
5. Dmane
Dmane is another Golden Age Flash villain who could fit right into the current arc of The Flash. Debuting in 1946’s Flash Comics Miniature Edition, Dmane hails from a peaceful and technologically advanced 70th century. Not content with life, he uses the magnetic tech of the future to become the ruler of the planet. Eventually, he’s thwarted and put on trial for execution. As luck would have it, however, one of Jay Garrick’s time travel experiments accidentally sends the rogue to the past where he continues his criminal endeavors.
With his future origin and magnetic powers, Dmane could explore a new threat to Flash while also exploring the future stories that are so vital to the comics. His comic backstory could even be honored by having Dmane be a foe of the Jay Garrick Flash on the show.
More exciting is the fact that he'd likely be the most obscure villain in the Arrowverse, only appearing in a tiny comic inside a box of Wheaties.
4. The Eradicator
Before the Eradicator was a Superman villain, another foe held the name in DC Comics. Appearing in 1982’s The Flash #312, the Eradicator is actually fairly obscure. Still, his backstory would make him the perfect foe to be revamped for The Flash.
Originally a senator named Creed Phillips, the Eradicator is born as vigilante set to clean up crime in Central and Keystone City. Unlike the Flash, however, he uses his power to turn rogues into protoplasm. His violent edge would make a nice contrast to Barry and allow our hero to explore his lighter approach to a darker path he could chose.
Like Blacksmith, Eradicator’s backstory would also let him be slowly teased out over the course of the season. Team Flash could even develop a friendship with Senator Phillips, unaware of his alter-ego. In the comics, Eradicator also had a split-personality, with the more nefarious side being the killer vigilante. Like his dual life, this would let the show paint the villain in a more nuanced way and explore some new angles the show hasn’t really touched upon with its villains.
3. Kilg%re
First appearing in 1987’s Flash #3, Kilg%re is basically a living virus. Not dissimilar from Indigo on Supergirl, Kilg%re requires electrical systems and technology to survive. As such, the alien virus consumed its home planet before being trapped in a sort of limbo and somehow ending up on Earth. Due to the vibrational purgatory it dwells in, only those traveling at super fast speeds can see Kilg%re at first. Unfortunately, this leads to Barry accidentally unleashing the virus, which immediately attacks S.T.A.R. Labs.
With a technological threat, characters like Cisco would have to step up to the forefront of the action. Kilg%re would also provide a reason for Felicity Smoak to make another cameo on The Flash, something that always benefits every character involved.
As The Flash looks to the comics for new and interesting villains to pit against the Scarlet Speedster, the writers would be hard-pressed to find any foe as intriguing as Kilg%re.
2. T.O. Morrow
Like Double Down and Murmur, T.O. Morrow has already appeared in the Arrowverse. Unlike those other villains, however, we’ve yet to see Morrow on Earth One.
Showing up in season 1 of Supergirl, Morrow and his creation Red Tornado were hardly given their due. With a long history in the comics, Morrow is one of DC’s greatest minds and most dangerous villains. His genius and tech would rival Cisco and the rest of Team Flash, letting Morrow be a villain that the show could turn to for a season long arc.
Though dead on Supergirl’s Earth, Morrow would be the perfect candidate for a counterpart in the main Arrowverse. With his comic history and superior mind, he could easily cause all of the Arrowverse trouble as a crossover villain, or just pester the Flash for seasons to come.
1. Thinker
While any number of villains from the comics could be the next big foe Barry faces on season 4 of The Flash, the Thinker is pretty much a sure thing. The original Thinker debuted in 1943’s All-Flash #12 as a Golden Age rogue. Since then, a few people have taken the mantle and the villain has faced Firestorm and Batman. Still, the original version, one Clifford DeVoe, is who we’ll be seeing on the Flash.
Both Abra Kadabra and Savitar have mention his name in association with Barry, hinting that Thinker is a big bad on the level of Zoom and Reverse-Flash. Aside from just being a genius, Thinker has both telekinetic and mind control powers thanks to his tech. By focusing on a more scientific minded villain, The Flash could switch up its formula and let other members of the team take the spotlight.
Plus, the Thinker could prove the ringleader of a number of other villains, from Kilg%re to Blacksmith. At this point, it’s all but given that the Flash will face Thinker soon, and the story opportunities the villain presents will help elevate the show.
