I’m never going to watch the video. It’s not a good time right now, and I don’t think there will be a better time where I will be interested, because I disagree with the little information I have about it. A better description would help.
Kirk’s Gorn was the captain. Maybe he was old and feeble? Not suited for a fight, still pretty strong but no longer fast and agile. The Metrons chose the captains, not the best fighters.
There was also a Klingon scientist in the Enterprise 2 parter about how the Klingons got smooth heads. He even talked about what it was like being a scientist in a society of warriors.
The whole deal with that is that they did it, in TOS, without any sort of explanation. We just had that dude, who McCoy discovered was really a Klingon, even though he looked just like a human. That whole thing is just adding an explanation for something that was long-since already there.
Also, you sound like you’re talking about the Orions. Do Klingons even have scientists? Somebody has to build the ships!
