The Slaughterhouse Nine, often simply called the Nine, were a rotating group of nine supervillains who roamed North-America. The group was founded by King, but was quickly taken over by Jack Slash, who killed King with the aid of Harbinger in 1987.[1]



The Slaughterhouse Nine was originally founded by King. In 1987, Jack Slash and Harbinger managed to kill King, allowing Jack Slash to take command of the group. Following King’s death, Harbinger retired from the Nine.

At some point in the late 1990s, the Nine came to Brockton Bay and interrupted a meeting between Empire Eighty-Eight, Marquis, and the Teeth. Jack provoked a bidding war for the Nine’s services, which the Teeth won. The Nine carried out the Teeth’s request to attack the Protectorate, then turned on the Teeth and drove them out of Brockton Bay.[2]

They were known to frequent areas previously visited by the Endbringers,[3] to take advantage of the chaos.

Brockton Bay[]

The Slaughterhouse Nine arrived in Brockton Bay for a second time in early June of 2011.[4] They initially split up in order to recruit each of their chosen individuals as candidates for membership, scouting out these candidates for several days and speaking to them on June 7th and 8th.[5] Their arrival prompted the heroes and villains of Brockton Bay to meet in order to discuss how to combat the Nine.

During this time, Cauldron also sent Battery a note telling her to let Siberian and Shatterbird escape the city alive.[6] [7]

After the Undersiders were forced to leave the meeting, the Slaughterhouse Nine confronted them in a parking garage. Jack Slash told them that each candidate would be tested by every member of the Nine in turn, ending in Jack Slash; failure of a test would lead to death or worse.[8] During this confrontation, Tattletale revealed that Cherish was plotting to take control of the Slaughterhouse Nine, something Jack Slash and Bonesaw had already countered. Jack Slash injured Tattletale for revealing this information. After this, Tattletale proposed a game to Jack Slash: if more than half of the candidates survived the tests, the Nine would only take the voluntary recruits with them and leave the remaining survivors.

Shatterbird sang thirty minutes after this confrontation. Following this in quick succession, Mannequin attacked Skitter’s territory and was driven off by her, and the Slaughterhouse Nine killed all the Merchants except for Scrub, who could harm Crawler.[9]

Jack delivered the finalized rules of the game the next morning, giving each member of the Nine a time limit to administer their tests and prohibiting individuals who were not Brockton Bay residents from interfering. The Nine’s rules stated that they would win if they managed to kill five of the six candidates.

In between the game’s beginning and the first attack, Imp infiltrated the Slaughterhouse Nine and failed to kill Bonesaw. She instead struck a deal with Cherish.

Mannequin was the first to take part, attacking Skitter once more. He was driven off by the Undersiders and saved by Burnscar, forfeiting his turn. The Nine were then ambushed by the Travelers and the Undersiders, who captured Shatterbird and Cherish. In the same confrontation, Grue was captured by the Nine and later tortured by Bonesaw. The Nine captured Skitter, Tattletale, Imp, Trickster, Sundancer, and Ballistic when they attempted to rescue Grue. Bonesaw began to torture them but was blindsided by Parian. Grue underwent a second trigger, killing Burnscar and freeing his allies.

The Nine and the collective Parahumans of Brockton Bay continued to clash, ultimately resulting in Bonesaw releasing a plague causing agnosia so that none of the defending parahumans could recognize each other. Panacea cured the plague, but the Nine managed to escape, recruiting Hookwolf and leaving behind a modified Cherish on the bottom of the Bay as punishment.

After Brockton Bay[]

Following their escape from Brockton Bay, the Slaughterhouse Nine visited several towns, including Stafford and Enfield in Connecticut, in order to recruit new capes to bolster their ranks.  One of these capes was Damsel of Distress. Additionally, Hookwolf participated in his first massacre with the Nine in one of these towns, helping Jack Slash and Siberian murder hundreds of people at a rural hospital. Bonesaw kidnapped Blasto from his new base in Boston, although the Siberian was killed in a skirmish with Dragon and Defiant. The Nine proceeded to invade the Toybox in order to use their technology. They set up a pocket dimension in a small town and Bonesaw placed the rest of the Nine in stasis while she began to clone their members, both past and present.

Contessa intercepted Bonesaw when she left the pocket dimension to get groceries and told Bonesaw to implant a control switch into the clones and give the switch to her at a later date. Bonesaw denied that she would do it, but over the course of the next year and a half, she came to change her mind.[10] She turned the switch over to Cauldron in June of 2013 following an interrogation by Tattletale.[11]

Slaughterhouse 9000[]

Main article: The Slaughterhouse Nine-Thousand

The Slaughterhouse Nine, bolstered by their clones, began their killing spree in the small town of Killington, setting traps and bodies in a spiral outwards from a message in the town hall. One Nice Guy was left behind to ambush the investigation team, which was made up of the Red Hand, the Undersiders, Weaver, and Golem. The Nice Guy was killed by Imp. Jack Slash also left a message for Golem, telling him that he didn’t meet his deadline. In spite of this, Jack Slash gave Golem another chance to kill him, without help. The deadline for this was set for five days away on the 24th at noon. Following this, multiple teams of Parahumans worked together in order to chase down the remaining clones and kill them.[12] 

Jack Slash then went to Ellisburg in order to recruit Nilbog and his minions. Weaver and Golem attempted to convince Nilbog not to join, but Nilbog attacked, resulting in Weaver grievously wounding him. His monsters, in revolt, join with Jack, who escapes with Nilbog’s body.[13]

The Slaughterhouse Nine were then pursued into their pocket dimension. The Nine having taken Aster, Weaver killed her along with a Cherish and a Screamer in case Aster’s power was what sparked the end of the world. The rest of the Nine escaped the pocket dimension.[14]

Golem and Weaver’s group pursued them to Los Angeles, which had been warped by Bohu. They confronted Jack, Gray Boy, the remaining Siberian, and other various members of the Slaughterhouse Nine Thousand.[15]

After observing how Jack seemed to be aware of everything around him, Golem ordered a PRT trooper to attack Jack, successfully distracting him for a few seconds. Sensing weakness, Grey Boy looped Jack before being killed by Foil. Jack was buried in containment foam.[16]

Despite being trapped, Jack was able to talk to Scion about his views on predation and cruelty. Scion broke Gray Boy’s loop and then went on to destroy the United Kingdom, beginning Gold Morning.[17]

  • The Slaughterhouse Nine were the focus of Worm's one year anniversary bonus, a series of eight interludes released over the course of a week. Each update, for the most part, centered around the 'Nine' and their meetings with various candidates in Brockton Bay.
  • Jack Slash and Harbinger were no older than 12 when they killed King.[32]

  1. “Jack,” Jacob said.  He kicked King’s body again.  “Fuck it.  He always called me Jacob, practically purring.  His little killer in training.  As if I could match up to his Gray Boy.  I want to be more than that.  Get out from under his shadow.” - Excerpt from Interlude 21.x
  2. “Years ago. Allfather still ruled Empire Eighty-Eight then. They held a big meeting between all of the factions. We stopped by. Great fun. I don’t think they accomplished a thing that day. We provoked a bidding war instead. Group called the Teeth wound up hiring us to kill some members of the Protectorate team. We did it, and then we wiped out the Teeth before leaving the city.”

    The Slaughterhouse Nine must have been new, then. People today would know better. Hopefully. - Excerpt from Interlude 11b
  3. “The Slaughterhouse Nine,” Clockblocker leaned back in his seat, groaning, “Fuck, that’d be all we needed.”

    “Wouldn’t be the first time they’ve arrived at a location in the wake of an Endbringer event,” Flechette pointed out. - Excerpt from Sentinel 9.4

  22. Jack had turned gray. Trapped, looped.

    “Pathetic,” Gray Boy said. “Stupid, useless. I thought you’d do something interesting, but you made yourself prey, instead of the predator. If you’re going to be prey, I want you to be my prey.”

    It dawned on Golem. Gray Boy froze him. - Exerpt from Interlude 26b
  23. “Reporting from New York. We told Bonesaw Jack was down, and she just surrendered. No idea what to do.” - Exerpt from Interlude 26b
  24. Colin stopped in his tracks. Dragon’s suit was posed with its head pointing toward the sky. The suit’s metal jaws were clamped around a body.


    “The Siberian is dead?”

    “Gone would be a more appropriate word,” she said. “Manton is dead.” - Exerpt from Interlude 19.x
  25. Hookwolf slashed out, extending a long, wavy piece of metal to cut at the crossbow. Foil pulled it out of reach, but her shot went wide, sailing off into the distance.

    She drew her rapier from its sheath, throwing it in the same motion.

    It penetrated Hookwolf, sailed past him to impale the side of one of the tombstone like buildings.

    Hookwolf wavered, then collapsed into a heap that looked like it would make for an exceedingly dangerous game of pick-up-sticks. - Exerpt from Interlude 26b
  26. He hopped onto his feet in a single movement, slashing with the spear’s point. The tip struck Damsel across the eyes, blinding her. He reversed the spear and swung it, and the spear-butt caught her in the side of the head. She was knocked down onto all fours before she could direct her power at him again.

    The man dug the spear’s point into the ground to help propel himself towards her. His leg flared with a gray blur as he reached her, and be brought it down onto her back from above.

    It sheared through her as though she weren’t even there, cutting her in half. He kicked out to obliterate her head and one of her shoulders in a single movement, disabled the gray blur, and set his foot down with a thud that rang through the underground laboratory. - Exerpt from Interlude 19.x
  27. 27.0 27.1 “Two suits destroyed. And we don’t yet know what Bonesaw took with her. Jack escaped with some of his team. But we killed four of them, all together.” - Exerpt from Interlude 19.x
