Balance of Terror, TV Original Series Episode

day.
Star Trek II: The Wrath of Khan, Movie
The best of the original films, Khan imported a strong villain from the

sacrifice provides the emotional wallop.
Unification, 'The Next Generation' TV Episode

The two-part episode ends with Spock grieving for his dead father by
mind-melding with Captain Picard.

This twisty time-travel narrative brings Picard's new Enterprise into
contact with an older model of the ship that has leapt into the future
through a ''temporal rift.'' The quantum fiasco creates an altered
timeline that must be rectified.
Best Destiny, Novel
Published in 1992, this Star Trek novel finds an older Kirk on the verge of retirement and involved in an adventure that will reveal details
about his troubled teenage years and serious father issues. The
