And indeed, why the Vauxhall Nova didn’t sell in Spain.
I’m shocked and surprised that this thread lasted so long without someone coming up with Autofellatio Man.
Don’t forget your various incarnations of Gang Initiation Man. Maybe a Gang Initiation Gang?:
Headlight Flasher
Penis Chopper
Strych9er
Ankle Slasher
Backseat Burglar
And my personal favorite, The Abandoned Shoe
Actually, a search for “gang” brings up all sorts of useful ULs regarding individuals involved in random acts of non-existent violence.
Call him : Hitchhiker V. 
Ah, actually a different UL. (The knock-out knock-off perfume salesmen stalking Wal*Mart parking lots.)
“Ether Bunny” does have way better visual appeal, though.
Cambodian Christmas.
Look out! It’s Vietnam Beaver!
'cause, y’know, Jerry Mathers and all…
Okay, how’s’about… “Watch out! It’s Son of Mister Green Jeans!”
Razor Blade Candy
Bat Boy (sure to go early)
Dead Paul (as in McCartney)
The Dingo
Missing Kidney (I know organ harvesting has already been mentioned, but it seems like there are a lot of good names spinning off of it)
The House Caller (I couldn’t get this down to 15 characters, but you know, the THE CALL IS COMING FROM INSIDE THE HOUSE!!! one, possibly my favorite UL simply for the sheer hysteria of the reveal)
Kinda veering off from ULs into conspiracy theory …
Fox Alien Baby
Area 51
Grassy Knoll
JFK’s Brain
Hey, don’t go stealing my Vietnam Beaver idea! I already have him created on Victory! 
How about a spiney Spidery Cactus.
Vanishing Hitchhiker = Thumber Poofs.
Man Mommy
Democrat Hurricane – needs to be shorter.
Green Arrow’s evil counterpart **Pluck Yew. **
The Swinging Munchkin
The Unsteerable Lighthouse.
Hoobert Heever
The Pink Wizard
The VietNam Beaver
Monkee Manson
The Crucified Santa
So what’s the deal with this City of Heroes thing exactly? I like some of these ideas and I might want to use them in something myself, but I don’t want to steal anything from anybody.

CoH is an MMORPG (massively multiplayer online roleplaying game) based on the superhero genre. You create a superhero character and play online with others. You can play most things solo, but sometimes you have to team up with others. We’ve got a supergroup called CECIL–like the Justice League, only savvier–on the Virtue server. Various subsets alsohave characters in other supergroups.
This discussion revolves around a major expansion that will hopefully be out next year. In it, players will be able to create and play villains and (among other things) fight the hero characters in PvP (player vs. player combat). The Urban Legends (or whatever we decide to call it) would be the evil counterpart of CECIL, spreading ignorance instead of fighting it. We’re discussing the personifications/originators of various well-known urban legends as villain characters. I envision the motto being something like: “We’re the ‘they’ in ‘That’s what they say.’”
I can’t speak for anyone else, but I don’t have any objection to you using my suggestions in other projects. They’re basically pulled straight from Snopes and tightened up to fit the character limit on names. If you’re daft enough to want to write about the actual characters once they’re created, you should probably consult whoever builds them. And, of course, you’ll have to use a different setting or get permission from CoH.
Oh, and Peter, the Swinging Munchkin idea can go in so many wrong directions. I love it. But, if the 15 character limit stays, it won’t work. Maybe The Hung Munchkin instead?
3Men&ABabyGhost
The High Babysitter - make a hippy looking girl, that has some sort of microwave beam power.
Velvet Cake
Haskell Cooper
Ded Kat Casserole
Res’rection Mary
Toilet Snake
(Mind you, any of these would also make great band names)
Without resorting to Google, who is this? Any connection to D.B. Cooper, the guy who supposedly parachuted into the Pacific Northwest with a bundle of stolen cash?
I don’t know if you’d be allowed to use that. Bat Boy is AFAIK a trademark owned by the Weekly World News.
I thought the dingo really did eat her baby.
Back To The OP
Revenge Bunny
Based on the UL of kids tying a stick of dynamite to a rabbit, who hides under their car as soon as the fuse is lit. Explosive/fire powers.
Admiral Keg
Based on the UL of a couple moving into a house and finding a keg of aged brandy. When they finish the keg, it’s still heavy. They open it to find the preserved corpse of a naval officer. Is there an acid or ooze power that sprays harmful liquid?
HiBeams
Based on the UL of a killer hiding in the backseat, and a trucker trying to warn the driver with highbeams. Blinding light, and a sonic weapon (for the horn ya know)
Fatal Boot
Based on the Ul of a cowboy boot with an envenomed fang that kills its wearers. A posion based power which requires contact.
Hell Hole
Based on the UL of a deep hole found to be a portal to hell. Sonic weapon to represent the screams of the damned.
McWorm
Based on the UL that McDonald’s burgers are actually ground worms. Either a slime spewing power, or a worm spewing power.
