The silver rocket ship flown by Tom Paris as Captain Proton in his black-and-white holodeck serial, complete with levers, sparks and a robot sidekick.
Captain Proton's rocket ship is a holodeck creation seen in several Voyager episodes, beginning with Night, where Paris and Harry Kim, as Proton and his sidekick Buster Kincaid, use it to pass the time while the ship crosses an empty region of space.
It has its largest role in Bride of Chaotica!, when photonic aliens mistake the programme for reality and go to war with Doctor Chaotica. Paris and Tuvok take the rocket to Chaotica's Fortress of Doom while Janeway plays Arachnia, Queen of the Spider People, to lower its lightning shield.
The design affectionately copies the film serials of the 1930s, with a finned hull, bench seats and controls that do very little. The ship returns in Shattered, when Chakotay and a Janeway from the past walk into a time-fractured holodeck still running the programme.
