Holographic publican in the Fair Haven village program whose charms led Janeway into a romance with a hologram.
Michael Sullivan was the proprietor of the public house in Fair Haven, Tom Paris's holographic re-creation of a nineteenth-century Irish village. Played by Fintan McKeown, he caught Janeway's attention in Fair Haven, and she quietly altered his program to make him more to her taste before deciding that a romance with a hologram was unwise.
In Spirit Folk, the program's long run caused the villagers to notice the crew's strange powers, and Sullivan learned the truth about Janeway and her ship before the program was repaired.
