1. Salt Vampire

From: ‘The Man Trap’ (Star Trek, Season One)

What is it? A cross between the Sarlaac (that toothy, sucking gob) and Bigfoot, this crafty inhabitant of planet M-113 has been hiding out as Nancy, the wife of scientist Dr Robert Crater, and a former flame of Dr McCoy.

This thing can disguise itself as anyone, trap its victims, then reveal its true face and suck the salt from their body like deranged hoover.

Cheesy or cool? Cheesy. It might have the ace ability to appear to be all things to all men (and women, since it can also assume male shapes), but when revealed in reality, the beast is pure rubber camp.

Still, it makes us worry that Megan Fox might be hiding something…

Fact me ‘till I fart: This was the first Trek monster seen by TV audiences - The Man Trap launched the show in 1966.
