10 Star Trek Moments You Never Saw Coming

10. From Hell's Heart, I Stab At Thee

While the death of Khan himself may not have been the biggest shock that Star Trek II: The Wrath of Khan had to offer, his actions spelled certain doom for one of the core members of the Enterprise's family. We are speaking of course about what is, arguably, the greatest tear-jerking moment in the entire franchise.

As Khan spits his final curses at Admiral Kirk, the Genesis Torpedo begins to activate. Unless the ship can get away, it, along with all of its crew, will be claimed by the matter transforming energy waves, before being wiped out of existence. With Scotty suffered acute radiation sickness, things are looking especially dire.

Spock's sacrifice frequently tops the polls of the saddest moments in all of Star Trek. There had been a leak in advance of the film that Leonard Nimoy would receive a death scene in the film, though director Nicholas Meyer tormented the audiences by including the Kobayashi Maru test at the film's beginning. Therefore, when the Vulcan entered that chamber, the audience was howling along with Scotty and McCoy, knowing full-well that there was only one possible outcome - even if it would be undone in the following film.

Spock's death, even when one knows its coming, still shocks and saddens to this day.
