As all science fiction fans will know,Star Trekis one of the oldest sci-fi series that’s still running. It started in 1966 and introduced multiple live-action and animated series, often with different Enterprise crews, along with many books, games, and comic books.

With a fandom of such extent, it makes sense that over time, some inconsistencies emerged inStar Trek. They were something the fans noticed and were quick to comment on. However, even all the inconsistencies and smaller or bigger errors don’t mean that anybody who likes space opera or just science fiction, in general, can’t enjoyStar Trekand everything it has to offer.

5The Klingons Look Much Different From What They Used To

In the originalStar Trekseries, Klingons were in many ways similar to humans, except for the fact that they all seemed to have darker skin and hair. The subsequent series introduced the best-known version of Klingons, the one that mostStar Trekfans think of when somebody says Klingon. This is what Worf, the first Klingon serving in Starfleet, looked like (minus the long flowing hair).

But the newest seasons portrayed Klingons that looked very much differentfrom what they used to both inStar Trek: The Original Seriesand inStar Trek: The Next GenerationorStar Trek: Deep Space Nine. And the change isn’t necessarily for the better. The newest series made them look very inhuman and monster-like, even though not all Klingons are violent fanatics who want to destroy everything around them.

4An Advanced Tech They Shouldn’t Have

It’s natural that the newerStar Trekshows have a more scientific look to them thanStar Trek: The Original Series. The first series had a limited budget, and it reflected in how the starship Enterprise and its equipment looked.The ships in the newerStar Trekserieshave much more modernistic equipment. That creates a continuity problem, though, since the first two seasons ofStar Trek: Discoverytakes place even before the original series, so by all rules, their equipment and ship should be less modernistic. The change makes sense in the Abrams movies where Nero’s time travel changed everything but not so much in theStar Trekshows.

Aesthetics aside, the crew also has inventions inStar Trek: Discoverythat isn’t supposed to exist yet - because they didn’t have them in the original series. The replicators are a good example of one such inconsistency since they only appeared in the Federation’s ships in the 23rd century, not the 22nd. In other words, Picard or Sisko already had them, but not Kirk so the crew ofDiscoveryshouldn’t have them either. They also possess holographic technology, an advanced one, but once again, this sort of technology only became more available in the 23rd century.

3James T. Kirk’s Name

It’s a well-known fact that Captain Kirk’s whole name is James Tiberius Kirk and that he got both his first and middle name after his grandfathers. However, in the very firstStar Trekepisode with Kirk as the captain of the Enterprise, the series claims that Kirk’s middle name doesn’t start with the letter T, but with the letter R instead. This is shown when Kirk fights his former friend Gary Mitchell to the death on Delta Vega afterMitchell had been transformed, gained special powers, and became a villain.

Mitchell creates a grave for Kirk and the tombstone says James R. Kirk. Unlike otherStar Trekinconsistencies, this is a relatively small, albeit a still visible one, and it can be simply explained by the fact that in the series' beginnings, the creators hadn’t yet definitely decided what Kirk’s middle name would be.

2Spock’s Relationship With T’Pring

In the most recent live-actionStar TrekseriesStar Trek: Strange New Worlds, Spock and his fiancée T’Pring are quite close. They spend time together whenever they can and even are intimate. However, that’s not how their relationship looked like in the original series. In the original version, Spock and T’Pring were engaged as children but only saw each other again as adults on their wedding day on Vulcan.

T’Pring refused to marry Spock because she had her eyes set on another, and Spock and Kirk ended up fighting to the death. Considering thatLeonard Nimoy’s Spocknever had such a close relationship with T’Pring as Ethan Peck’s Spock does, it begs the question of whether Spock and T’Pring ofStar Trek: Strange New Worldswill stay together or whether their relationship will end up in a similarly dire way.

1No Female Captains?

In the final episode ofStar Trek: The Original Series, Captain Kirk’s old girlfriend and now an enemy, Janice Lester, tries to steal Kirk’s body. Her plan succeeds for a time as she and Kirk switch their bodies and Lester ends up controlling the Enterprise. According to her, stealing someone else’s body is the only way she could ever be a captain since Starfleet apparently doesn’t allow women to become captains. That’s not the case, though, as there have been female captains before.

One of them is Captain Hernandez who lived a hundred years before the events of the original series. And, of course,Star Trek: Discoveryintroduced two other female captains, Captain Philippa Georgiou and Captain Michael Burnham. In the end, it seems that Lester was mistaken in her assessment and attributed her inability to become a Captain to a rule presumably imposed by Starfleet. It’s true thatfemale captains are still a minority inStar Trek, butthat doesn’t mean there aren’t any.
