However, Revo quickly betrays them, leaving them for dead on a distant world.

Worf’s New Undercover Mission Could Seriously Hurt Him–on Many Levels

The history of relations between the Klingons and the Romulans goes back at least to the era of Captain Kirk. At various points in theStar Trektimeline, the Federation has been enemies of the Klingons and the Romulans, and for a very brief period, the two species came together, as seen in the third seasonStar Trekepisode “The Enterprise Incident.” The alliance did not last long, leading to an intense hatred between the two galactic powers, one that continues to last deep into the 24th century. Worf’s own family fell victim to Romulan treachery.

Now, Worf’s new mandate, to handle Starfleet’s dirtiest missions, has forced him to become a Romulan, with the potential to trigger a major existential crisis. Both Worf and the Klingons as a whole have issues with the Romulans. The Klingons see the Romulans as sneaky, and having “no honor.” General Revo has conscripted Worf to help him stage a coup, and this turn of events cannot sit well with the Klingon, who has already expressed serious doubts about his future in Starfleet. The stress could lead to Worf having a nervous breakdown, and thus compromise his mission.

The Romulans No Doubt Ensured the Process Was Painful

The process of transforming Worf from Klingon to Romulan was painful, not only on a spiritual level, but on a physical one as well.

The process of transforming Worf from Klingon to Romulan was painful, not only on a spiritual level, but on a physical one as well. In theStar Trekuniverse, the modifications Worf and company underwent are done on a genetic level. This method was perfected by Nurse Christine Chapel, and as seen in various episodes ofStrange New Worlds, it can be an unpleasant process. While the Federation may have refined the technique by the 24th century, making it less traumatic, the Romulans emphasized nothing of the such, giving Worf’s transformation an even darker layer.
