  • First of the "evil twin" stories

    "The Enemy Within" used an idea that would crop up again during this run of STAR TREK - the Evil Twin. This time, Captain Kirk is split into two by a Transporter malfunction (another recurring story device) so that there's a good Kirk and a bad Kirk.

    Incredibly, those closest to him, Yeoman Rand, Spock, don't realise (until it's too late) that they're dealing with evil Kirk. But of course, that's where the fun comes from, with the audience yelling at the screen "Nooo ... can't you see it's EVIL Kirk?"

    So popular was the evil twin idea that the producers used it in the very next segment aired, "What are little Girls Made Of?", where an insane scientist constructs an evil Kirk android and sends it up to the Enterprise. And again, Kirk's nearest and dearest don't realise an evil duplicate is among them ...

    Don't you just love STAR TREK?
