10 Biggest Jump Scares In Star Trek

5. Extension Course In Sneaking Around

On a starship, there really is no better place to scare the living daylights out of someone than from the shadows of the Jefferies tubes. Prior to the borgification of his colleagues on the Enterprise, Miles O'Brien got quite the fright whilst working in the Defiant's very own metallic veins. If perhaps not enough to stir the viewer, 'Doctor Bashir' most definitely made the Chief jump. There was barely enough room to jump in the first place.

"Julian!" though not at all, was simply putting his engineering extension courses to good use… of course. As we know, the adversary of The Adversary wasn't the Tzenkethi, it was the Founder already aboard. As what was never Ambassador Krajensky jumped up and out the ceiling on the bridge, we jumped once more.

The scariest things aren't those that go bump in the night. Only the familiar turned against us is truly frightening. That and the Jefferies tubes! If the changeling could be anyone, no one could be trusted. The crew found that out the hard way a little later when the real Julian surprised them at the door. Right. That's enough duplicate Bashirs for now, thank you very much!
