Although they aren't anything like their modern personas, the villains that terrorized the original Batman series laid the foundation for future adaptations that followed. Joker is now a dangerous anarchist, the Riddler is a Zodiac-inspired serial killer, and Catwoman is a master thief and Batman's lover, but none of them would even exist if the original series didn't set the bar.
But as iconic as those characters are, there are still villains from the series that have yet to receive modern adaptations. While many of them were goofy and gimmicky, there are still some that could greatly benefit from modern adaptations. From interesting personalities to technological geniuses, there are several characters that are unfortunately still stuck in the '60s.
False Face
While not the most physically and visually impressive, False Face definitely has a compelling M.O. that would do wonders in a modern adaptation. Blending the stylings of Clayface and Black Mask, False Face is a master of disguise who uses his skills with makeup and effects to commit his crimes. In a modern setting, he would be quite the formidable foe in the fields of deception and espionage.
While not as monstrous as Clayface, False Face would definitely make life hard for the Dark Knight. A modern version of this shifty character would definitely need to make accurate use of his gift for multiple identities, maybe even keeping his true face a big secret well after the credits roll. He might not be the most eccentric of the Rogues Gallery, he'd definitely be one of the most dangerous.
The Siren
A modern Batman might be a bit too busy dealing with the Riddler and the Penguin to take on the seductive songs of the Siren, but that doesn't mean she wouldn't be a good fit for other DC heroes. Whether in the Arrowverse or up against Harley Quinn and the Birds of Prey, a contemporary adaptation of the Siren would make for a dose of interesting and musical mayhem.
An ideal scenario would have her in a screaming match with Black Canary, but to say she'd be a massive threat to the city is anyone's guess. That being said, it would be nice to see her brought to the forefront instead of playing second fiddle to the Riddler.
Shame
The original Shame was a criminal that took heavy influence from the western genre of movies and TV, complete with a Stetson and six-shooter, but a modern version would definitely be an impressive feat. With so many The Mandalorian relying on western themes in a different setting, a cowboy-inspired villain wouldn't be out of place in the DCEU.
If Shame went less Roy Rogers and more Clint Eastwood, there might be grounds for a truly threatening villain. If handled the right way, an outlaw-styled gunslinger with a custom-made set of guns made to pierce Batman's armor could make for a very interesting confrontation.
The Bookworm
While the version portrayed by Roddy McDowell might seem a little cartoonish and geeky compared to some of today's modern Batman villains, the Bookworm would be an absolutely devastating force in the age of information and technology. While he might not be using leatherbound tomes as his weapons of choice, his fiendish intellect and bookish nature would make him perfect for the role of a technological terrorist.
He's no Edward Nygma, but a modern Bookworm could be the human equivalent of Brainiac in a current Batman adaptation. If knowledge is power, the character could easily be rewritten as a power-hungry genius bent on world domination that would be a Justice-League-level threat.
King Tut
King Tut is certainly one of the more outlandish villains of the series, but there might be a way to bring him to the big screen. Considering Greek gods and other entities of mythological nature exist in the DCEU, logic dictates that a reincarnation of Tutankhamen could exist in the same world.
While it's not likely that Wonder Woman would go head-to-head against the professor-turned-pharaoh, the grounds for a modern adaptation are certainly there. Instead of being a case of imaginative identity, it could be a possession-fueled mummy's curse. If Ares can walk around in an army uniform in WWII, King Tut could raid the Smithsonian for magical artifacts.
The Mad Hatter
While he did get a version in that could give the Joker competition or a dark and sinister foe that leads Batman down the rabbit hole.
One thing a modern Hatter needs to take from the '66 version, aside from his collection of hat-based weapons, is his thirst for vengeance. In the series, the Mad Hatter planned to send batman through a deadly hatmaking machine with enough tools for a Saw trap. To say that a version combining these elements wouldn't work in a theatrical release would be utterly untrue.
Mr. Freeze (George Sanders Version)
Although Arnold Schwarzenegger brought the character to life in Joel Schumacher's infamous adaptation, a true-to-form Mr. Freeze has yet to be seen on the big screen ever since. And while the animated series gave fans the version the franchise knows today, the first version presented in the '66 series has more than a few qualities that would be excellent for a modern adaptation.
With his metallic suit and raygun that shot both ice and fire, Mr. Freeze is already incredibly well-equipped for a contemporary setting, but it doesn't end there. For something that premiered in the 60s, Mr. Freeze is armed with several technological wonders in his lair, such as the temperature-controlled environments that nearly freeze Batman and Robin to death. A modern version could learn a thing or two from the original.
Egghead
Egghead might be one of the most difficult villains to adapt to the modern world, largely due to the ing of Vincent Price, but he's easily one of the most enjoyable and entertaining of the original cast from the '60s. A modern Egghead would have to balance intimidation and intellect with the right amount of comedy to truly make it to the big screen.
There are plenty of actors out there who could do Egghead justice, but it would take a true amount of genius to keep the character from going too over-the-top. That being said, if the Riddler can evolve from a cackling prankster in a green jumpsuit to a masked serial killer, Egghead could certainly make the jump from a comedic know-it-all to a dangerous criminal mind.
