TOS: City on the Edge of Forever
TNG: The Inner Light
DS9: In the Pale Moonlight
TAS: never watched
Except for the VOY-Episode those are my absolute favourite episodes from each of the series.
They all fit perfectly the "tone" of each series, what it is about etc.
Especially "In the pale Moonlight" ... just love this ep.
For Voyager it's quite hard to find a fav, because I like it the least of them all, but Equinox fits the other criteria.
Enterprise has no fav, but I like the Xindi-Arc, so I guess i would show "The Expanse" or so ...
Checking to make sure my account merged over. Ignore this thread.
Or, if you're feeling compelled to post, name the Star Trek episode (from any series) that you would show to someone new to the franchise; which singular episode perfectly encapsulates Star Trek.
Show your work.
TOS: "Balance of Terror"
It shows the environment aboard a Starfleet vessel in a hostile situation and the reveal of a complex enemy who may not be as different as the protagonist's own. Two captains who are sworn by duty to uphold the interests of their own nations, with conflicts within their own crews on how exactly to go about it.
I would probably weight up the person but I would say;
TOS: City on the Edge of Forever - classic episode.
TNG: The defector - superb cat and mouse ep.
DS9: Way of the Warrior - pure awesome on all levels.
VOY: Timeless - brilliant time travel ep.
Ent: Azarti Prime - probably wont have a clue what's going on but its a super episode.
