The Beagle Boys in the Scrooge McDuck comics and DuckTales.
Before he lent his name to a summer blockbuster, The Fallen created one in the second volume of Transformers: The War Within. Decepticon mystics Bludgeon, Mindwipe, and Bugly were given vague mystical power upgrades and charged with gathering a team of (seemingly arbitrary) Transformers so that The Fallen could attempt to summon Unicron.
Manute in Sin City had a QMBS with him in Big Fat Kill which consisted of a midget, a wise-cracking Neo-Nazi, and an old guy who can make people feel pain just by touching them. The Irish mercs from the same story might also count.
In the Sonic The Hedgehog comics, there's the Destructix - composed of Lightning Lynx, Sergeant Simian, Predator Hawk, Flying Frog, Drago Wolf, and Sleuth Dawg - a group of incompetents who have worked for various Big Bads over the years, usually getting their butts kicked in the process. Recently, Drago left to work for Dr. Eggman and Sleuth retired, handing control over to Fiona Fox, who apparently has big plans in the works (which so far consist of breaking her boyfriendScourge out of prison so that he can take charge of the gang).
Recently, Dr. Eggman got a new group of enforcers in the form of the Metal Series — a group of Evil Knockoffs of several of the main heroes, led by the recently roboticized Mecha Sally.
