Quintessential Characters

[Armored Saint]

As a Vulcan, I see Sarek as the quintessential example - not Spock. As noted by others earlier, Spock is by definition, not a typical Vulcan - cannot be!

On the other hand, marrying human women is not really typical. Ironically, he was more more bothered by the half-humanity of his son than the full of humanity of his two wives. But yes, he's the one who defined Vulcans as major diplomats (despite they're closed on themselves).

For the Klingons, Kang and Kor were good examples; as Koloth was the opposite.

Koloth had in TOS something that became more romulanish in TNG, but he weas alson one of those treacherous Klingons. The drunk Korax opened the way for Klingons as biker gangs.

 

[Lapis Exilis]

For the Klingons, it has to be Martok. Every Klingon talks the talk. Martok walks the walk.

I think his wife Sirella could give Martok a run for his money as the most Klingon of Klingons.

 

[Use of Time]

I would choose Gul Evek as the quintessential Cardassian.

 

[AgentCoop]

Thanks, USS Triumphant! I completely blanked on that.

 

[USS Triumphant]

Thanks, USS Triumphant! I completely blanked on that.

I probably would have, too, if it wasn't also the screen name of one of the users here whose posts I read fairly often.
