10 Biggest Jump Scares In Star Trek

4. Not What The Doctor Ordered

Two's company, at least three's a proper Denobulan marriage. As we learnt from Doctor Phlox in Doctor's Orders, Denobulan cities, like their conjugal arrangements, were purposefully crowded. For Phlox, having just one person for company (or so it seemed) through the reconfigured space proved highly uncomfortable. As a basic premise, solitude did provide for some high-end scares.

On Denobula, hallucination was considered "a harmless way for the subconscious to release nervous energy". Its effectiveness would really rather depend on what was being hallucinated. T'Pol was one thing. A Xindi insectoid and a harrowing vision of Hoshi were another. There was also the very real Porthos, who got a jump scare of his own.

The stricter definition of jump scare comes mid-episode as Phlox was mid-rounds for the neuro-sedated. Hearing a noise from outside the hull of Captain Archer's quarters, Phlox approaches the window. Suddenly, the camera swings around. Dissonant sounds play. All we see is a shadow pass across the doctor as he recoils in horror. To paraphrase from an episode of Star Trek: Voyager with a, let's say similar, plot, hallucinations might not be real, but they certainly seem to be. "That's what makes them so frightening."
