Wallenquist Organization

The Wallenquist Organization is a criminal organization in the fictional universe of Frank Miller's "Sin City". It is led by Herr Wallenquist, a German-American (though the name is actually Swedish) mobster shrouded in mystery. The organization has a broad base of criminal enterprise to its name, including drug smuggling, assassination, organ harvesting and human trafficking for the purpose of illegal adoption and slavery, as well as having many city officials on their payroll at one time or the other.

Leadership

Herr Wallenquist aka the Kraut, is the mysterious and powerful leader of the organization. His goal is merely to achieve power and profit, regardless of what underhanded methods can lead him to that goal. His stature belies his power, as he is portrayed as being an enormous and imposing man who is of greater size and physical bulk than even Marv. Unlike the other antagonists, however, he is somewhat an honorable person, as he sees revenge as an unnecessary extravagance and will often take losses with a fair amount of dignity when hostile action will serve no practical purpose. He also proves to be one of the few men able to resist Ava Lord's wiles, and is rarely directly involved with the perpetration of his organization's crimes. He is comparable visually and as a character to The Kingpin from the numerous Marvel Comics titles.

Enforcers

The Colonel is an enforcer and captain for Wallenquist. Trains and coordinates assassins in the organisation's employ, as well as being one himself at some point. He runs the organisation's organ harvesting and human trafficking ring as well as other ventures. His operations are eventually shut down by the Basin City Police in a sting operation at the conclusion of the "Hell and Back" arc; he then is captured and shot by Commissioner Liebowitz for threatening his family. In the comics continuity, it is believed that he was "The Salesman" from the Sin City short story "The Customer is Always Right".

Manute, a huge black man, typically dressed as a valet, who is very gentlemanly and polite in all situations, even while committing homicide, who served Ava Lord and was later recruited by the Colonel and Wallenquist following her death at the hands of Dwight McCarthy. He is also nigh indestructible, having been crucified (by Miho), shot repeatedly (by Dwight), beat up numerous times (by Marv and Wallace), and relieved of an eye (again, by Marv). Manute was then put in charge of securing the corpse of Jackie-Boy to instigate a war between the police and the girls of Old Town, allowing Wallenquist to make a power grab for Old Town in the meantime; however, he was finally gunned down by the hookers of Old Town during 'The Big Fat Kill'. In the deleted scenes of the movie adaptation, he was shown to have momentarily escaped from the assault with Schutz and another thug, only to be sliced down the middle by Miho in an alleyway moments later.

Assassins

Delia aka "Blue Eyes", a trained assassin hired by The Colonel. She uses the powers of seduction to lead unsuspecting men to their deaths. She usually has sex with her victims before killing them. She herself is killed by Wallace, despite begging for her life.

Mariah, a trained assassin in league with Delia, although apparently less skilled. She, too, uses the powers of seduction, but can also fight with a bo (staff). She works for Wallenquist. Her nose was broken by Wallace, and she managed to escape from Liebowitz's assault on the factory. Has a penchant for leopard print clothing.

Gordo, The Colonel’s muscle. Works alongside Delia to try and set-up Wallace's death, although he is seemingly only proficient in pushing cars down hills and shooting people. Very dumb, and speaks in third-person. Was killed by Wallace after he mortally shot Captain.

Others

Bruno, a former hitman and politician on Wallenquist's payroll. His murder at the hands of the Mafia, and the collateral damage that ensued, set Dwight on a mission to find his murderer.

Becky, a young Old Town prostitute who is instrumental in getting Jackie Boy killed by Miho. She also works for the Colonel as a spy, mainly because she didn't want her mother to discover that she was a prostitute, partly because he offered her a considerable sum of money and a new life. Killed during 'the big fat kill'. In the epilogue of the movie adaptation, it is implied she is killed by the Salesman while leaving the hospital.

Maxine, a psychopharmacologist who works alongside Delia. She administers a strong hallucinogen into Wallace's system, and later gives him the antidote at gunpoint, but she is killed when Wallace accidentally shoots her. She was also involved in Esther's attempted brainwashing.

Doctor Fredric, a doctor in league with the Colonel. Kidnaps and overpowers Esther under the Colonel's orders after incapacitating Wallace with narcotics in "Hell and Back". Mariah kills him and his companion, Orrin, to make sure that Wallace doesn't subtract any valuable information from him.

Orrin, Doctor Fredric's assistant and lover. Shoots and incapacitates Wallace with a strong tranquilliser whilst he and Fredric abduct Esther. Mariah kills him before killing Doctor Fredric.
