Star Trek has officially joined forces with the X-Men universe, introducing one of Marvel’s most terrifying adversaries: the Sentinels. Known for their relentless pursuit of mutants, these formidable mechanical foes have earned a reputation as some of the most chilling threats in the Marvel Universe. The unsettling nature of the Sentinels parallels that of Star Trek’s menacing Borg, and the 1998 crossover comic, Star Trek: The Next Generation/X-Men Second Contact, combines these two iconic entities to create a truly harrowing narrative.
In this intriguing storyline, Captain Picard and his crew from the USS Enterprise find themselves in Earth-616—the primary universe of Marvel. Their arrival disrupts the fabric of space-time, opening doors for the sinister Kang the Conqueror, who deftly exploits the chaos to orchestrate his plans.

As these two universes entwine, Picard and the X-Men grapple with a horrifying combination of Borg and Sentinel forces, set in an even darker version of the classic ‘Days of Future Past’ timeline.

Major Threats: Sentinels and Borg





Since their debut in the mid-1960s, Sentinels have posed an ever-looming threat to mutants. Originally created by Doctor Bolivar Trask, these enormous robotic enforcers were designed to hunt down and eliminate mutantkind. Ranging from colossal machines to microscopic variants capable of self-replication, the Sentinels epitomize the malevolent potential of technology devoid of ethical considerations.
In contrast, the Borg represent the quintessential villain within the Star Trek universe. This collective of cybernetic organisms is driven by the singular ambition to assimilate diverse species, merging their biological and technological distinctiveness into a cohesive whole. First emerging in the episode “Q Who?” from Star Trek: The Next Generation, the Borg’s chilling presence has remained a pertinent threat across multiple series and films, such as Voyager, Enterprise, and Picard.

Upon encountering this eerie Borg/Sentinel hybrid, Picard and his crew are understandably horrified. Combining the most formidable threats from each franchise was a brilliant maneuver that explores the darker nuances of technology’s role in society. The Sentinels, spawned from fears of racial supremacy and societal paranoia, exemplify how technology can be weaponized, while the Borg illustrate the dangers inherent in unrestrained technological integration.
While Second Contact briefly engages with the concept of these Borg/Sentinel hybrids, it ultimately leaves much of their nature up to viewers’ interpretations. Within their head units lie what appear to be Borg drones; however, during the confrontation against the X-Men, these drones remain dormant, creating an enigma about the true essence of this hybrid threat. The presence and purpose of the Sentinel drones add layers of intrigue to the narrative.
In the larger Star Trek timeline, the period following World War III is referred to as the “post-atomic horror.”This backdrop provides a fitting context for the unsettling Borg/Sentinel hybrid. Narratively designated as “post-atomic New York,”this timeline resonates with X-Men fans familiar with the grim landscape portrayed in the classic “Days of Future Past,”where mutants are hunted to near-extinction. While both narratives reflect dystopian futures shaped by nuclear fallout, there exists a crucial divergence: Star Trek’s humanity eventually overcomes its darkest chapter, whereas mutants in the X-Men universe continue to suffer persecution.
Star Trek: The Next Generation/X-Men: Second Contact serves as a whimsical exploration of both franchises, marking Marvel’s second venture into the realm of Star Trek comics. This one-shot effectively intertwines elements from both universes, highlighting their common themes. With the inclusion of the formidable Borg and the relentless Sentinels, it showcases two of the most memorable and terrifying villains from their respective narratives. Though the swift pacing of Second Contact means some story developments remain underexplored, particularly regarding the Borg/Sentinel hybrids, the rendition still resonates as a striking moment that leaves its mark on both franchises.

Despite initial backlash from fans during the first crossover of Star Trek and X-Men, the Second Contact installment demonstrates the potential richness of such narratives. The chilling variant Sentinels introduced in this story embody the shared values, fears, and technological themes prevalent in both franchises. The synthesis of Sentinels and Borg exemplifies not only their dark nature but also the compelling storytelling that arises from their intersection.
