Let' face it: all the really good ideas for comic book villains were taken by, oh, around 1942. The writers have just been scraping the sides of the jar since then.
As proof we offer these villains who, in real life, couldn't frighten a gazelle.
8The Penguin From Batman
The Penguin is a pudgy man dressed in evening wear who likes birds and has the power to disguise weapons as umbrellas. Obviously, liking birds isn't frightening or even illegal, unless it involved liking birds in a carnal way, which he doesn't. That leaves us with umbrellas.
So, here's a typical Penguin encounter with basic sports-stadium security:
Security: Sir, can I ask you to step aside?
Penguin: (pretends not to notice)
Security: Sir. In the top hat and monocle.
Penguin: Oh, my, dear fellow, are you talking to me?
Security: Yes, sir. Can I take a look at your umbrella?
Penguin: Oh, this? Why, it's just an ordinary umbrella. A fellow can bring an umbrella with him on an outing, can't he?
Security: The sky is completely clear and it's 90 degrees, sir.
Penguin: Well, yes, I know, this is just an old man's foible, you see, and-
Security: Sir, you're clearly the Penguin, and I-
Penguin: (shocked) How did you know?
Security: ... you're clearly the Penguin, and I can't let you bring an umbrella in here.
Penguin: Son of a bitch.
How To Make Him More Threatening:
We're not going to go the easy route and just replace "penguin" with "velociraptor." No, we want to stick to the creator' original vision as closely as possible. So let' go with another flightless bird, the turkey. Turkeys have those dangerous talons and can continue living with their heads cut off.
Oh, hey, there you go. The Headless Turkey. Picture that, this man-sized thing, standing there pointing a gun at you, with a ragged hole where its head was. You don't even know what the thing wants because it can't talk. It just stands there gesturing with the gun, while little spurts of blood jet softly from its open neck. OK, that' terrifying. Let' move on.
