20. Clock King

Suicide Squad membership or no, the fact remains that this Green Arrow and Batman enemy was born dumb: With no special powers, he’s just a “badly dressed” guy who “enjoys clocks very much,” per the pop-culture critic Seanbaby.

19. Calendar Man

If you can judge a villain by the terrifying company he keeps, here’s who this Batman villain hangs with: Killer Moth. On the plus side, Calendar Man is good at keeping track of holidays and other special occasions.

18. Polka-Dot Man

From the get-go, this Batman foe means business, announcing his plan to “use my inventive dots to make my name throughout the underworld.” Inventive dots!? Did he say inventive dots…!? The horror…!

17. Gadget Maker

As a contestant on Shark Tank, we bet this guy could kill. As a Wonder Woman foe, his jewelry box “of doom” is both underwhelming and condescending.

16. Selena

We appreciate that this big-screen Supergirl villain is making her way in a male-dominated world. We’d appreciate her even more if Faye Dunaway’s over-the-top performance didn’t keep reminding us of Joan Crawford and Mommie Dearest.

15. Lenny Luthor

One of Superman IV: The Quest for Peace‘s many bad decisions was to make Lex Luthor’s accomplice his Valley-guy-talking nephew (Jon Cryer). It’s, like, totally cringe-inducing.

14. Bat-Mite

We understand that being a DC fan means accepting a degree of whimsy (and a fair number of gorillas—more on that last one in a bit). So, to Mister Mxyzptlk, we say fine. But to Bat-Mite, we say enough with the imps!

13. Shaggy Man

This villain gets the nod because of WhatCulture.com calls a “profoundly stupid origin story,” which can be boiled down to two words: salamander DNA.

12. Gorilla Boss

When the late, great Julius Schwartz ran DC Comics, he had a rule: “one gorilla a month.” For every legit character the directive inspired (see: Gorilla Grodd), we got another where the writers slapped a human brain into an ape and called it a day.

11. Ross Webster

In Superman III, this tycoon aims to corner the market on coffee. This isn’t to say coffee isn’t a valuable commodity; this is to say it’s a small-sounding scheme for a supposedly outsize character.

10. Gargantua

Not to be confused for Marvel’s Gargantua, this simian Gargantua—again with the apes!—was created for the 1970s Wonder Woman TV series, and by created we mean producers “recycled…gorilla appliances” from Planet of the Apes.

9. Mad Mod

This Teen Titans foe is as menacing as Austin Powers—and as frozen in time, too.

8. Lorelei Circe (aka the Siren)

This made-for-TV villain (the worst from the 1960s Batman show, per Paste) was not made for the age of ear buds. When the Siren lets loose, hitting a note “two octaves above high C,” you’ll be wincing with pain.

7. The Terrible Trio (aka the Fox, the Shark and the Vulture)

This band of animal-mask-wearing criminals sounds like the start of a bad joke, i.e., A fox, a shark and a vulture walk into the Batcave…

6. Film Freak

When this Batman foe assumes the identity of Psycho’s Norman Bates, that’s one (appropriately disturbing) thing. When he dresses up as King Kong, that’s another thing. DC doesn’t need more gorillas.

5. Kancer

Kancer is like cancer, see. The difference is its cell-destroying properties are spurred by kryptonite rather than cigarettes or whatever. Ugh.

4. Bizarro Batman

Where the Superman-inspired Bizarro is nothing if not original, the floppy-eared Bizarro Batman (no true relation to the legitimately menacing Batzarro) is just a pronoun-misusing copycat.

3. Gus Gorman

The dumbest thing about this dumb villain from Superman III is that the movie and, we suspect, Richard Pryor, want us to to believe Gus isn’t a villain at all, but rather a harmless bumbler who doesn’t mean to commit all the crimes he commits.

2. Kite-Man

We would mock this Batman foe, but Batman: The Brave and the Bold does it so much better when it has the character openly voice his ambition to be the “most famous kite-related person in history.”

1. Nuclear Man

It’s hard to take a villain seriously when he, one, looks like he uses a lot of Sun-In, two, hoists an obviously fake moon rock like it’s an obviously fake moon rock, and, three, stars in Superman IV.
