10 Most Horrifying Star Trek Moments
8. Commander Remmick's Head
This scene is of course infamous in Star Trek. It is one of the most graphic death scenes in the franchise, coming completely out of nowhere - in The Next Generation's first season to boot.
Starfleet has been infilitrated by a race of parasites, with the parasite's queen being embedded in the unlucky Commander Remmick. This is particularly unfortunate, as he had been aiding Admiral Quinn in attempting to root these monsters out.
Upon discovery, Picard and Riker aim their phasers at him, firing with such intensity that he is first forced back into his chair and then, in a grotesque display, his flesh is seared away from the muscle and his head quickly explodes.
And it doesn't stop there.
His torso begins to dissolved, revealing this alien queen and her parasites around him. The two men fire again, destroying the queen, but leaving an eviscerated, decapitated Remmick behind. It is a scene of pure nightmare fuel, succeeding in ensuring the episode was censored for years following its transmission.
