10 Biggest Jump Scares In Star Trek

6. Assimilators Awaken

'Leave no trace' should be as much a principal of time travel as it is of responsible camping. Regeneration, or 'What the Enterprise-E Didn't Clean Up'. Forget the 'butterfly effect'! Nothing even remotely so delicate awaited those scientists in the Arctic. The scares of the episode relied on a sense of irony between character and viewer. We knew everything about the Borg that they didn't. With that, we were waiting to jump out of our skins. And we did.

In a horrifying twist on the Monty Hall problem, there was just one door with two Borg drones behind it. They might have looked dead on those tables. They were just a bit cold. "You seem a little jumpy," said scientist Drake to scientist Rooney. Oh yeah? Hold my hand scanner! 

"PULSE. RESP. CELL RATE. EEG." Four flat lines with a lot of power. Just don't go messing around with what we know to be a transwarp coil! Oh, no. Never mind! Those lines are getting awfully excited. The Borg breathed again, as we inhaled sharply. Drake and Rooney returned to find their colleague full of nanoprobes. The drone was behind them too. Our hearts missed a few measurements.
