They can’t all be the Joker or Hugo Strange, can they? Batman has been part of the zeitgeist for eighty years now. In that time, Batman has amassed an array of villains ranging from disturbing to menacing to comical and all points in between. Batman wasn’t always dark and gritty, nor was he always a fun-loving billionaire playboy. His villains reflected not just the times they were created in, but the creative team as well. In the right hands, the Joker could be downright whimsical or absolutely terrifying.

Some bad guys, however, always seem to be a bit of a joke. Would you fear rogues with names like Crazy Quilt or Kite-Man? Maxi Zeus sounds like it could be a product found in your local pharmacy, rather than a supervillain ready to terrorize Gotham. There are also strange villains that on the surface seem like they couldn’t hurt a fly, much less the Dark Knight. But the reality is that some of those Rogues are among Batman's and Gotham’s most dangerous foes. Here are 10 Batman Villains That Seem Lame (But Are Actually Very, Very Dangerous).

10 Baby Doll

Batman defeats Baby Doll

Baby Doll looks like her name sounds. As part of the classic Animated Series, Mary Louise Dahl is an actress born with Systemic Hypoplasia, a condition that will always leave her a looking like a little girl. That clearly drove her insane—that, and her show Love That Baby getting canceled.

She would kidnap the cast of the show so she could have her family back. While she’s yet to make an appearance in the comics, kidnapping a bunch of people puts you definitely in the "force to reckon with" column.

9 Egghead

Batman 1966 Egghead

Egghead likes eggs and egg puns—is that a shock to anyone who ever watched the pun-tastic Batman sixties TV series? The odd-looking villain was played by the master of horror Vincent Price in a very different role for him.

With all of the egg puns, it’s hard to take him seriously, but he’s also smart enough to deduce Batman’s secret identity, which makes him a big-time threat any day of the week.

8 Penguin

He’s been one of Batman’s most enduring villains, but that doesn’t mean that Oswald Cobblepot doesn’t look completely silly. He’s a heavyset, stocky man with a monocle and an umbrella for every occasion.

But the Penguin has still found a way to become one of Gotham’s most influential gangsters, supervillains, and, sometimes, politician. Despite his comical look, the Penguin has done some vile things to remain a constant thorn in Batman’s side.

7 Firefly

Setting fires to things with a homemade flamethrower should make anyone menacing and a viable threat to heroes like Batman, but then Garfield Lynns decided on the codename Firefly.

Depending on who’s telling the story and what timeline the story is in, Lynns is a failed special-effects worker. Sort of like the Mysterio of the DCU. Unlike Mysterio, Lynns’ flamethrower and his attempts to burn Gotham to the ground are always very real and very dangerous.

6 Calendar Man

Performing a holiday-themed crime during all sorts of holidays seems silly, but Julian Day, aka The Calendar Man, can do some major damage. The creative team of Jeph Loeb and Tim Sale brought him back from mothballs as a pseudo-Hannibal Lecter type of character in The Long Halloween.

There, he tried to offer insight on how to catch Holiday and knowing who Holiday really was. He returned in the sequel, Dark Victory, and nowadays, to add to the gross-out factor, only ages with the season.

5 The Mad Hatter

On the surface, any Batman fan worth their weight in Batarangs knows that Jervis Tetch, The Mad Hatter, is just a knock-off of the Alice In Wonderland character. But in the Batman world, that look, however funny, inspires all kinds of fear and dread in Gotham’s citizens.

Tetch is not only obsessed with the book, but he’s also obsessed with perfecting mind-controlling technology, sometimes to hypnotize even Batman. More disturbing is his creepy obsession with little girls, especially ones named Alice.

4 Professor Pyg

The name Professor Pyg sounds like something out of a Muppets or science show. The mask sometimes looks like that, too. Other times, the pork-man looks straight out The Texas Chainsaw Massacre. But the guy is seriously messed up!

His quest to perfect the human race began with releasing an identity-destroying virus throughout Gotham. He uses brain surgery and mind-altering psychotropics to permanently fix doll masks to his henchman to help carry out his schemes.

3 Crazy Quilt

Despite being created by the King, Jack Kirby, the name really does say all you need to know about the silliness of Crazy Quilt. He is a painter/master criminal (aren’t all artists?) and is accidentally blinded by a gunshot wound. He undergoes corrective surgery and now can only see bright colors.

He is accidentally blinded again by Dick Grayson as Robin and subsequently hates the Boy Wonder even more than Batman. He has even come close to beating Jason Todd nearly to death several times for Grayson’s transgressions.

2 Humpty Dumpty

As if a villain named “Egghead” wasn’t lame enough, how about the egg-shaped Humpty Dumpty? Ol’ Hump’ isn’t actually a big-time villain per se, but it doesn’t take much in Gotham to turn towards the mouth of madness.

He has an uncanny ability to fix things that he deems to be broken. The guy has been down on his luck since birth and always tried to understand how to fix the world around him—beginning with his grandma, who he once dissected and tied back together with a bootlace.

1 Ratcatcher

DC Comics' Ratcatcher.

Only in Gotham would the world exterminator be a bad guy. Otis Flannegan was an actual rat catcher, but a life of crime was more appealing. He’s unlike most pest control workers, though: Flannegan can actually talk to rats!

If you think that doesn’t sound scary, then you’ve never been in a subway station watching a rodent eat a forsaken cheeseburger. Or worse - you’ve never watched Willard. The guy not only controls a rat army but can manipulate cyanide and various other poisons.
