Star Trek: 10 Story Arcs You Can Binge In A Day
3. The Augments
The Episodes:
Enterprise: "Borderland", "Cold Station 12", "The Augments", "Affliction", and "Divergence"
TOS: "Space Seed"
Movies: Star Trek II: The Wrath of Khan and Star Trek Into Darkness
The Background:
In their own right, the three Augments Trilogy episodes from Star Trek: Enterprise are standouts, but they also lead directly into the events of the two Klingon Augment Virus episodes to form a five-part story.
Depicting the first resurrection of the genetically engineered supermen that menaced Earth in the 1990s and the Klingons' attempts to harness that genetic power themselves, Star Trek: Enterprise's Augments and Klingon Augments episodes lead seamlessly into the classic TOS episode "Space Seed". "Space Seed" of course introduces us to Khan Noonien Singh who would go on to menace the Enterprise crew in Star Trek II: The Wrath of Khan and (to a lesser extent) Star Trek Into Darkness.
Yeah, you can skip Star Trek Into Darkness as it's basically a Kelvin Timeline retelling of Wrath of Khan, but the six Prime Universe-set episodes and the movie are required viewing for the full Khan/Augments backstory and for those who just love big hair and torn up biker clothes.
