An elderly holographic resident of Tom Paris's Fair Haven programme who, with his friend Seamus, becomes convinced that Voyager's crew are supernatural beings.
Milo is a character in the holodeck village of Fair Haven, played by Ian Abercrombie. He appears in the sixth-season Voyager episodes Fair Haven and Spirit Folk as one of the regulars at the pub kept by Michael Sullivan.
In Spirit Folk the simulation has been left running for so long that its characters start to perceive things they were designed to ignore. Milo and Seamus compare what they have witnessed, from a punctured tyre mended with a word to a girl turned into a cow, and conclude that Paris, Kim and the others are spirit folk.
The two stir up the townspeople, who take Paris and Kim prisoner and seize the Doctor's mobile emitter. The crisis ends when Captain Janeway allows Sullivan to see Voyager for himself and the villagers decide to accept their unusual neighbours.
