An austere Delta Quadrant people who avoid spiced food, intoxicants and frivolity, whose ambassador enthusiastically abandons all restraint aboard Voyager in Someone to Watch Over Me.
The Kadi appear in the Voyager episode Someone to Watch Over Me. They live by a strict code that prescribes plain food, modest dress and regular prayer, and they regard most pleasures as dangerous to the spirit.
In 2375 Janeway and Tuvok visit the Kadi to open trade talks, and the Kadi ambassador Tomin comes aboard Voyager in exchange. Neelix is assigned to look after him and is warned to respect his customs. Tomin, however, cannot wait to try everything that is forbidden at home, from rich food to synthehol and holodeck company.
He ends up drunk and unconscious at a reception hours before his superiors are due. The Doctor uses some of Seven of Nine's nanoprobes to clear the effects from his system in time for him to greet them soberly. The subplot runs beside the Doctor's lessons in dating for Seven.
