|Jack the Ripper|
|First appearance||Kif Gets Knocked Up a Notch|
In a malfunctioning of the holo-shed on the Nimbus, the hologram of Jack the Ripper along with the holograms of Attila the Hun, Evil Lincoln, and Professor Moriarty came to life and caused mayhem on board the ship, until Zapp sent them by accident into the vacuum of space by blasting a hole in the ship's hull. While it is presumed that this event would have killed him, he may have been brought to life again after in another instance of the simulator malfunctioning. This can be guessed based on the fact that Evil Lincoln who accompanied him in the first malfunction later appears back on the ship in Kif's room.
