Murder Rat is an hybrid cape, created by Bonesaw to be a member of the Slaughterhouse Nine. She was a combination of Mouse Protector and Ravager.

Appearance and PhysiologyEdit

Murder Rat had hands and feet with three-foot-long machete blades attached to them.[1] Her eyes were small and nearly buried behind her altered face and brow,[1] which had been altered into something that was more rat-like than human, conelike, ending in a squashed black nose that had staples around it. Bonesaw had added a second set of teeth, all canines, so that the woman would have enough as her jaw was stretched forward. Drool constantly leaked between her teeth in loops and tendrils. She was pale, except for her face and patches all down her body, where patches of ebon black skin were stapled in place.[2]

Although seemingly a single woman, Bonesaw had combined parts of Mouse Protector and Ravager, using transfusions of bone marrow and viruses with modified DNA inside them until even Panacea couldn’t tell for sure where one woman started and the other began. She had one and a half brains contained in a synthetic fluid in her skull.[2]

There was a metal framework throughout her body, controlling her, rigged to kill her with needles surrounding her heart if it was ever disabled.[2]

The clones of Murder Rat boasted enhanced senses.[1] They were not held together with staples.[3]

Abilities and PowersEdit

Murder Rat is a composite of Mouse Protector and Ravager and possesses both their powers, blended into one.[1][2] Weaver noted that she had "a dozen" minor powers.[1]

When she cut someone with her blades, the wounds would begin fizzing and emitting smoke that stung eyes; they took a long time to heal, and almost always left a scar. Left untreated, they would usually bleed out. The effect was more intense when she was close by.[1]

She was able to "tag" something or someone by scratching them[4] using Ravager's ability to sense people they injured and Mouse Protector's power to teleport to those she had touched,[5] although the blooming smoke made it more obvious who she was teleporting to.[1]

Her skin was "as tough as leather", and she had some kind of enhanced strength, flexibility, reflexes and agility.[1]



Bonesaw made Murder Rat as a created addition to the Slaughterhouse Nine. She was a member in full having passed the requisite examinations. Yet over time the Horror would slowly fall apart and lose the brains and skills that had made her such a terrifying presence. In the end she was just a rapidly putrefying corpse being used as a lacky.[3]


Disabled by Panacea using her power, as a test by Bonesaw. Mercy-killed by Mark Dallon.[2]


Several clones of this character appeared as part of the Slaughterhouse Nine-Thousand, despite being a Bonesaw creation. She is the only hybrid cape to be cloned multiple times.[3]

Trivia Edit

When membership had been down, Bonesaw had made Murder Rat as a created addition to the Slaughterhouse Nine. She’d passed the tests, but degradation in mental and physical faculties over time had seen to her demotion. - Excerpt from Interlude 25
