Why does Chekov say that he remembers Khan in "Star Trek: The Wrath of Khan" if in Star Trek TOS Chekov doesn't appear in the episode "Space Seed"?

Also why is Chekov in "Star Trek Into Darkness"?

Do I miss some chapter from Star Trek TOS that answers this?

    As I recall there's no explanation given for this, but I haven't seen The Animated series and it's been a long time since I watched all of TOS. +1 for interest Oct 29, 2014 at 16:29

    Remember ... this is a reboot of Star Trek. Things are not going to be exactly the same. I mean, this time it was Kirk in the warp chamber getting fried and not Spock. You could ask the same question there. You can also assume that Chekov, while not in the episode, would have been somewhere on the ship ... he would have known about Khan. Oct 29, 2014 at 17:31
  • Yes, because the Spock Paradox but about The wrath of khan? Oct 29, 2014 at 17:33

    I wasn't around in the 1800s, but if Napoleon showed up in front of me I might say that I "remembered" him, in the sense that I recognize that the man standing in front of me is the same man I had learned about previously. "I remember him" can be shorthand for "I remember hearing about him."

  • @Nerrolken: But it's the other way round here; Khan encountered the Enterprise before Chekov was on board (if we choose to believe that his not being among the bridge crew indicates he was not yet a member of the crew at all at that time - questionable). It's like Napoleon saying he remembers you, even though you had not been around in the 1800s. Dec 3, 2016 at 20:19

Space Seed was supposed to be a bottle episode. As few of the regular cast was to be used as possible. Since the Enterprise was on a 5 year journey, we would presume the ship didn't run back to HQ and drop everyone else off; rather only those few regulars were shown as being instrumental to that particular script.

In this case, only Kirk, McCoy, Spock, and Scotty were shown. Uhura, Chekov and "Oh My!" err, I mean Sulu were not. This was to save money for the hiring of the Guest Star, Ricardo Montalban, who portrayed Khan.

In universe, this would not mean that all of the other crew wouldn't know what was happening, rather they just weren't instrumental. Chekov would still have known about Khan and his crew, as would Uhura and the others not shown in the episode.

    Chekov didn't not show up to save money; he didn't show up because he didn't exist as a character yet (he was created for season 2 and "Space Seed" is in season 1).

    However, when Kirk mentions corbomite (fictional explosive) for the second time in TOS, Chekov nods and smiles, suggesting he was around for the first corbomite episode, just not on the bridge at the time. There are 430 people on the starship, and we see like 10 every week. It's possible he was assigned to some other part of the ship but was still aware of Khan.

    I stand by the idea behind what I said, which was 'reinforced' by Barry Carter. We see the "heroes", the rest of the crew are background. Chekov may very well have been in the crew, just in the shuttle bay, or hydroponics, or whatever. Again, it's a five year voyage, out to where no one has gone before (or as the original said, no man...)

  • Wowsers! All this time and I misspelled Uhura and the catchphrase of George Takei and no one corrected me!

Not to compete with the above answer by CGCampbell, but just to add some further information, Memory Alpha has the following to say on the matter:

Khan's apparent recognition of Chekov and his remark "I never forget a face" are somewhat ironic, since Khan's appearance in TOS: "Space Seed" was in the first season and Chekov did not make his first appearance until Star Trek's second season. It is possible, however, that Chekov was on the Enterprise at the time and Khan had seen him off screen. In fact, as noted in the Special Edition DVD's text commentary, Walter Koenig often joked (at conventions and in interviews) that his character had made Khan wait overly long to use a bathroom on Khan's visit to the Enterprise and that was why Khan remembered his face so well.


This really doesn't present a problem at all. The Enterprise had a crew of over 400 people, the vast majority of whom we never see. Chekov was obviously a crew member, just not one of those precious few we get to see until his more prominent assignment (on the bridge) in seasons 2 & 3.


Also why is Chekov in "Star Trek Into Darkness"?

Star Trek into Darkness is in another timeline refered often as the Kelvinverse due to "Kelvin" (in this case the U.S.S. Kelvin) being a recurring name reference in Bad Robot works with Kelvin being a reference to JJ Abrams grandfather of the same name...

SPOCK: You are assuming that Nero knows how events are predicted to unfold. To the contrary, Nero's very presence has altered the flow of history, beginning with the attack on the USS Kelvin, culminating in the events of today, thereby creating an entire new chain of incidents that cannot be anticipated by either party.

UHURA: An alternate reality?

SPOCK: Precisely. Whatever our lives might have been, if the time continuum was disrupted, our destinies have changed.

The timeline was first created in 2009 Star Trek (the previous film) where in the future of the prime timeline, Ambassidor Spock fails Romulan from being destroyed by a nebula. A survivor with his crew named, Nero seeking revenge, uses "red matter" to create an articifical black hole and they and Ambassidor Spock time travel back in the time line (at different times), creating an alternate time line (possibly a branch off. Most Bad Robot shows that us time travel opperate this way and I am pretty sure Alex Kurtzman has been quoted saying the new timeline runs parallel to the prime, suggesting it is not "gone").

With that, the point (much like Fringe and possibly LOST) is that a new chain of events ensue and challanges what can change and what can stay the same looking at the alternate TOS characters. It's basically a look at identity through free will vs fate (or reciprcoity), when one has to consider a timeline being made from another...

So Chekov can be there, because the events of how the TOS characters come together are not the exact same.
