Star Trek: Strange New Worlds may be ready to introduce the Klingons in season 2
The Klingons were a huge part of Star Trek: The Original Series. They and the Romulans were among the more consistent villains the original franchise ever had. Since Strange New Worlds is a prequel to that franchise, it would make sense to see them and even the Romulans in Strange New Worlds.
Not only that, but Strange New Worlds is the sequel series to Discovery, a series that featured the Klingons to a pretty high degree. While the they weren’t the most well-received part of that series, they were heavily featured.
So it’s not surprising that Strange New Worlds’ actor, Babs Olusanmokun, hinted at the iconci alien race in the upcoming second season while discussing his character, Dr. M’Benga’s backstory. The interview took place on Paramount+’s the Ready Room, hosted by Wil Wheaton, and Olusanmokun talked about how M’Benga will have to deal with another side of himself due to the Klingons;
"What we’ll see in the next season–that we are already shooting–is essentially exploring another side of Dr. M’Benga… a darker side of him. We can say [it’s] an exploration of his… contentious relationship with the Klingons."
The Klingons will need to be retooled if they come into Star Trek: Strange New Worlds
Star Trek fans have not been a big fan of the redesign Klingons introduced in Discovery. While it’s true the original films re-designed the aliens first, that version of them was wildly accepted and loved, unlike the more modern incarnations.
With Strange New Worlds serving as an in-universe prequel to The Original Series, the hope is that they start showing a change in the Klingons, that makes them look more like the Original Series version.
Finding a way to bridge the look of them from Enterprise, where they looked like your classic version, to Discovery (where they looked pale and more like cone-heads) to the original series version where they were far more human-looking is going to be key.
Also, putting in a back story about their genetics and why they keep changing is also going to be a major point of emphasis for the season if they’re introduced.
