I recall from decades ago that one of the cartoon Star Trek episodes had Kirk meeting a version of himself from a previous cycle of the universe. The universe was suppose to be cyclical, oscillating between expansion and collapse, with the big bang being the transition from collapse to expansion.
I browsed the episode synopses on Wikipedia, but none seem to correspond. Can anyone recall which episode this was?
The character of James Kirk only encountered "himself" on four occasions;
'TOS: The Enemy Within' in which a transporter accident splits Kirk into 'Good Kirk' and 'Evil Kirk' before being reintegrated by transporter.
'TOS: What Are Little Girls Made Of?' where a sophisticated Kirk android is created and then destroyed.
'Star Trek VI: The Undiscovered Country' in which a shapeshifting alien briefly impersonates Kirk before being disintegrated.
'TOS: Mirror, Mirror' featured an "Evil" version of Kirk from a mirror universe. At the end, this character was returned to his proper place.
For the record, there are no instances of him being duplicated in the Animated Series, none of the TV episodes dealt with a cyclical universe, nor is the 'cyclical universe' itself a feature of the Star Trek fictional universe which would strongly suggest that this wasn't a trek episode.
As an aside, although Star Trek usually subscribes to the "Big-Bang, Big-Crunch" theory, the episode TAS: The Magicks of Megas-Tu dealt with another theory of universe creation, that of the Steady State.
Kirk: Captain's log, stardate 1254.4. For years scientists have theorised that if our galaxy was created from a great explosion, then the centre of the galaxy might still be creating new matter. The Enterprise is now on a science mission to investigate.
