Vilix'pran was a crew member on Deep Space 9. A member of an unknown species, Vilix'pran was assigned to cargo inventory in 2371, but Julian Bashir made a request for the ensign's transfer because he was budding with twins. Bashir and Miles O'Brien were throwing him a baby shower; O'Brien was also building him a hatchling pond, while Bashir had ordered baby clothes from Garak. A prior budding had produced four offspring. (DS9: "Heart of Stone")
Jake Sisko babysat his hatchlings on several occasions, a task which involved preventing their wings from getting tangled. (DS9: "Business as Usual")
By 2373, Vilix'pran had been promoted to lieutenant, and was in the process of budding for a third time. The nature of his species' reproductive system meant he could be expecting anything from eight to eighteen hatchlings, and he requested larger quarters from Major Kira. (DS9: "Apocalypse Rising")
- In "Business as Usual", Jake referred to Vilix'pran as Ensign Pran. Presumably, this was just a slip of the tongue, and Vilix'pran was still a Lieutenant. It also seems to indicate that "pran" was similar to a human surname.
