A fussy museum curator who travels aboard the USS Voyager when the USS Cerritos escorts the famous ship to Earth to become an exhibit, and sees his careful displays run amok.
Beljo Tweekle appears in the Lower Decks fourth-season opener Twovix. He is the curator responsible for the USS Voyager, which has been preserved with displays recalling its years in the Delta Quadrant and is to be installed on Earth as a museum.
The Cerritos is given the job of escorting Voyager, and Tweekle insists that nothing aboard be disturbed. His exhibits prove more dangerous than expected when a series of accidents reactivates relics of the old ship's adventures, including the macrovirus, holodeck characters and other hazards, which take over Voyager and start merging its systems.
Boimler, Mariner and the other lower deckers bring the ship back under control before it reaches Earth, sparing Tweekle's collection and earning several of them promotion to lieutenant junior grade.
