Was almost Star Trek: Prodigy Season 2 featuring the Borg?
Indeed, the Borg could have been the main power in the Mirror Universe in an other reality the Star Trek: Prodigy writers investigated. Originally thought of for episode 14 "Cracked Mirror," this other reality would have shown a situation whereby the Borg had absorbed Captain Janeway and the USS Voyager, so rendering the Mirror Universe under their control.
In This Other Reality, What Would Have Happened to the Protostar Crew?
Driven to ally with the merciless Mirror Janeway to fight the Borg's threat, the young crew of the Uss Protostar would have been in a terrible position. This unusual alliance would have been a dramatic turn, stressing the urgency of the matter and the possibility of improbable heroes arising against apparently insurmount challenges.
Why dropped this alternate reality?
The authors regretfully chose not to include this storyline into "Cracked Mirror." Although the exact motivations for this choice are unknown, it is most likely related to limitations on the running length of the episode and the wish to concentrate on the dynamics of the Mirror Universe. The episode still looks at how a mirror universe affects known characters and their relationships, but the Borg's inclusion might have eclipsed these interactions.
How might the Borg have changed the Mirror Universe?
The Borg's presence in the Mirror Universe might have changed its power structure entirely. Imagine a world in which the Borg's assimilation technology had proliferated unrestrained, poised to wipe all life in its unrelenting quest of excellence. Renowned for her merciless ambition, the Mirror Janeway might have even exploited the Borg's might for her own benefit, generating a quite horrible and unexpected situation.
What interaction with the Borg would the Protostar Crew have had?
Young and inexperienced Starfleet hopefuls made up the Protostar crew would have been unprepared for the Borg's extreme might. For the crew, this confrontation would have presented a major obstacle requiring them to rely on their wit, creativity, and the help of improbable allies like the Mirror Janeway to survive. Their meeting with the Borg might have been a turning point in their growth since it pushed them to their boundaries and made them face the actual nature of their own bravery and fortitude.
Could Future Star Trek Series explore this Alternate Reality?
Although the Borg's appearance in the Mirror Universe is still a lost chance for the second Star Trek: Prodigy season, there is always a chance this concept may resurfaced in next Star Trek productions. The idea of a Borg-dominated Mirror Universe is full of possibilities for gripping narratives that highlight the terrible results of unbridled power and the frantic fight for survival in a universe run over by a relentless, assimilation-driven force.
