A suave associate of the villain Hippocrates Noah in Julian Bashir's 1960s spy holosuite programme, who takes on the physical form of Worf in 2372 in Our Man Bashir.
Duchamps is a holographic character in the fourth-season Deep Space Nine episode Our Man Bashir. He is the elegant lieutenant of Hippocrates Noah and is first met at a casino in Paris, where Bashir and Garak try to win an introduction to his employer.
After a transporter emergency the patterns of five officers are stored in the holosuite, and Duchamps appears with the body of Worf. He takes the two visitors to Noah after overcoming them with a drugged cigar.
He remains at Noah's side through the climax in the mountain stronghold. As with the other altered characters, Bashir must make sure Duchamps is not killed before the crew's patterns can be retrieved.
