20 Most Messed Up Deaths From The Star Trek Movies

14. Migraine For Marcus

Blood runs thicker than water. So do brains. That is if Alexander Marcus had any to begin with. 'Badmiral,' and a bad dad, he was more than a headache for daughter Doctor Carol Marcus over in Kelvin. No Genesis in Star Trek: Into Darkness, but still a lot of skull-crushing "Khaaaaan!"

Well, you know what they say, if you want peace, unfreeze one of history's most notorious villains and force him to work for you on the militarisation of Starfleet, including the creation of the mahoosive Dreadnought-class ship called — what else — the 'USS Vengeance,' because war with the Klingons is inevitable anyway. That's a loose translation from the Latin, of course!

Naturally, that plan didn't last long. Even under an alias, and looking a lot like Doctor Strange without the goatee, Kelvin Khan was every bit as devious as his Prime counterpart. He absconded, blew up a small chunk of London, killed Admiral Pike, and long story short, eventually caught up with Admiral Marcus for a bout of comeuppance.

Though the camera cut away for the most stomach-churning moment of her dad's quasi-decapitation, Carol's blood-curdling scream was all we needed to comprehend the horror. Carol had been quite rightly "ashamed," before being probably very, very sick!
