Jack the Ripper also known as the Whitechapel Killer is one of the ghosts haunting the Haunted Mansion.
Jack the Ripper is the ghost of a famous serial-killer who roamed London in the late 19th century where he killed anywhere between five and eleven women in the alleys of Whitechapel with surgeon-like precision. Despite his fame his identity was never revealed and he was never caught by the authorities. His portrait portrays him as an obese moustached man with green eyes, and high society menswear, something done to concur with the theory that the Ripper was a high-society doctor who's murders might have been a covered up. He stands in a dark alley at night in front of a lamppost as he brandishes a knife.
Much like the other Sinister 11 portraits Jack's portrait features the "staring-eyes" effect which was accomplished by painting pupils on ping-pong balls cut in half. The eyes were cut out and the balls were set behind the portrait and lit, giving guests the impression that they are moving.
- At Tokyo Disneyland's Mansion he was supposed to be featured in the "Burial Crypt of Famous Villains" along with Nero, Dracula, Bluebeard, Medusa, and Attila the Hun.
- In Concept Art, the Ripper was shown to have the foot of one of his victims stuffed in his coat pocket. While historically it was known that the Ripper dissected his victims to steal body parts; this one only done with internal organs (and in one case a nose).
- The portrait seems to give into the common theory that the Ripper was a wealthy doctor given his outfit in the scene. The portrait makes him look most like suspect James Maybrick but considering that Maybrick didn't become a suspect until the 1990s, this is likely a coincidence.
- Several real life analyses of Jack the Ripper's preserved genetic samples done in the mid-late 2010s put forward that Jack the Ripper was a deranged barber named Aaron Kosminski. This was not known when designing the Haunted Mansion variant of the character however and is more trivial to Jack the Ripper's real-life counterpart.
