Unnamed Holodeck characters
The Hitman
The Hitman (right) with Worf at Keystone City
The Hitman was a major character in the Orient Express holodeck program aboard the USS Enterprise-D. In the encapsulated world of that historical train, his part was that of a stereotypical gangster: sinister, brutal, yet smartly dressed and polite.
When the holodeck became a focal point in the birth process of a new lifeform in 2370, The Hitman impersonated a threat to the Enterprise officers. With the holodeck safety protocol disabled, his sidearm could have proven deadly, as deadly as it had been to the holographic character of the Engineer. As the program progressed, it became evident that it was The Hitman's task to protect the early phases of the emergent lifeform's generation. Having completed this task by "laying the foundation" in a symbolic act at Keystone City, he exited from the scene. (TNG: "Emergence")
- Played by actor Vinny Argiro.
Kapitän
The Nazi SS officer
The Kapitän (Captain) was a holographic German officer used in a holoprogram created by the Hirogen when they captured the USS Voyager in 2374 and used its crew in simulated games for their hunts.
The Kapitän was a member of the Nazi party who had impregnated the character which B'Elanna Torres was playing. A brutal man, he was in charge of a province in France. He was ultimately killed by Klingons, who were part of another simulated hunt scenario, in the final battle for the town. (VOY: "The Killing Game, Part I & Part II")
- The Kapitän was played by J. Paul Boehmer. Kapitän actually refers to a naval captain in the German military. Since he was an SS officer the correct rank would have been "Hauptsturmführer" or at least "Hauptmann" to reflect the army branch.
