The truth is that some villains are more marketable than others. That's why when it comes to Batman, a lot of the same villains are recycled. In many cases, it makes sense to use more iconic villains to draw in viewers/readers thus earning a profit but there are also extremes to this way of thinking.
Over time, some fans are just tired of seeing some villains constantly show up and that they should be given a proper vacation. These same fans would rather see some of the more forgotten villains come back to get their own time in the spotlight. This has happened before with villains like Calendar Man and Victor Zsasz, and should had more often.
10 Revamp: Killer Moth
For many, Killer Moth is considered a joke villain, but why should that stop the character? If Calendar Man can be rebooted into a Hannibal Lecter-esque villain, why can't Killer Moth receive similar treatment? The odd thing is that he technically has.
Over the years, DC has tried to revise and reboot the character, but he never received enough time to really showcase himself. DC should let the character breathe in more stories and become the new terrifying threat to Gotham City.
9 Overused: Jason Todd
There's no denying that Jason Todd has made quite the impact on the DC universe after his resurrection. He's dark, complex, and makes for some of the grittiest Batman-related stories ever told. That being said, DC has become a little too obsessed with turning Jason Todd into a show-stealer.
The best case of this was in Batman: Arkham Knight where his appearance felt forced and less impactful. Plus, over the years his constant bouncing between hero, anti-hero, and villain has become a bit tedious.
8 Revamp: The Clock King
After getting a revamp in Batman: The Animated Series, not much was done with Clock King afterward. Sure, he's appeared in comics from time to time but mostly as a glorified cameo. Even the CW's Arrowverse did more with Clock King than the comics have.
The Clock King has the potential to be one of the more sinister villains due to his mastery of time. Knowing how every little detail of Gotham will hit on the exact second, including someone's fighting style, is scary. His schemes could be just as deadly as the Riddler, delving more into a domestic terrorist angle.
7 Overused: Ra's Al Ghul
The most tiresome plot twist of Batman stories has been the reveal that it was all orchestrated by Ra's Al Ghul. This trend seemed to come about after the success of Christopher Nolan's Batman Begins. Granted, it worked well in that story but so many movies, games, and comics have since felt the need to force Ra's Al Ghul in there somewhere.
Ra's Al Ghul's entire scheme is also a cliché due to so many other villains having the same motivation. The world is irredeemable so the villain is attempting to wipe out humanity in order to properly restart. Until they can come up with an angle that makes Ra's stand out from that pack, it's best to just give him a break.
6 Revamp: The Great White Shark
Most Batman fans probably have zero clue about Warren White, aka Great White Shark, a psychopath with sharp teeth, no lips, no nose, and no hair. He's similar to Kingpin from Marvel where he runs a criminal empire from his own prison cell in Arkham Asylum.
He was a crooked financier in life which has turned him into Gotham's deadliest loan shark, hence the name. DC seems to have just forgotten this villain and the last memorable use of him was as a riddle to solve in Batman: Arkham Asylum. He definitely deserves a new take.
5 Overused: Bane
Bane has risen in villain ranks over the years, becoming a rival to Batman along with the likes of the Joker, Deathstroke, and Penguin. Bane has held Gotham in an iron grip, he's broken Batman's back, he's "killed" Alfred, and he has been featured prominently in the Injustice universe.
There's never really been anything overly egregious with Bane other than maybe his appearance in 1997's Batman & Robin. In terms of the comics, he's been great, but he has been used a lot. DC should give it a rest with Bane before the character becoming annoyingly overplayed.
4 Revamp: Clayface
Another annoying cliché: The antagonist was just Clayface in disguise. This one has been used a lot to retcon certain events and deaths, which makes fans roll their eyes. Clayface is one of the most unique of Batman's villains and deserves more than being an overblown red herring.
The story of Clayface is also a darker one that could lead to some great stories. Instead, Clayface is mostly just used for one-off fights and cameos. Clayface is technically one of the more powerful of Batman's metahuman foes so he could lead his own giant story arc as well as Bane or Harley can.
3 Overused: Catwoman
Out of all the love interests that Batman has had over the last eighty years, why is DC so adamant about pushing Catwoman? It's not like Catwoman is good for Bruce, seeing how they break up and get back together more times than soap opera leads.
This relationship reached the highest point of toxicity when the two had their fake-out wedding that was hyped up for so long. Batman deserves someone better, and much like Jason Todd, Catwoman's constant jump between good and bad is just annoying at this point.
2 Revamp: Anarky
After appearing as a minor character in the Arkham-verse, Anarky (aka Lonnie Machin) has seen a bit of a renaissance. He had a brief role in the Arrowverse and was even in the often-overlooked Beware The Batman animated series.
Still, Anarky has yet to be used to his full potential by DC. He's essentially the antithesis of V from V For Vendetta who wants to destroy all of Gotham for twisted reasons. His side mission in Batman: Arkham Origins was small but memorable; showcasing the potential Anarky has for comics and even the films if given the chance.
1 Overused: Joker
It's pretty unanimous that despite the Joker's charisma and icon status, fans are kind of sick of him. Between the endless film incarnations, comics, TV shows, and video games, Joker is the prime definition of an overused villain.
A case can be made for the character's continued relevance: He is Batman's equivalent of James Moriarty. The iconic foe and rival who is born to be Batman's enemy. That has worked for decades without a doubt, but even Sherlock Holmes faced other villains besides Moriarty. After Joaquin Phoenix's Oscar-winning role of the Joker and the disappointing Three Jokers story arc, it's time to give the Clown Prince Of Crime a hiatus.
