Sprok is one of the Enderprizians of New Enda-Prize, a people who imitate the crew of Kirk's Enterprise, and he takes the part corresponding to the Vulcan science officer Spock.
Sprok appears in All the World's a Stage, in the first season of Star Trek: Prodigy. The crew of the USS Protostar answer a signal and find a village whose inhabitants wear home-made Starfleet tunics, call their creed Starflight and name themselves after officers of the original Enterprise.
Their knowledge comes from a Starfleet ensign marooned on the planet about a hundred years before, whose stories were passed down and distorted. Alongside James't, Huur'A and Dr Boons, Sprok is the villagers' answer to Spock.
He is seen in the play the villagers stage about the coming of the Enterprise, a pageant that is revised at the end of the episode to include the young crew of the Protostar.
