I always wonder why the president of the Federation in Star Trek VI: The Undiscovered Country looks very similar to a Klingon. He has the characteristic high hairline, this "Fu Manchu moustache" and, most remarkably, those slight bulges on his forehead (while maybe not as developed as those of actual Klingons, they are still noticable). But given that the Federation is in an ongoing conflict with the Klingons with the parties only recently approaching each other, this seems quite odd, especially when left without any explanation in the movie. So is there any explanation for the president's unusual appearance or am I just imagining things?
The President of the Federation according to the Memory Alpha website, is actually an Efrosian, and not a Klingon. Granted there are distinct similarities...
Efrosians were invented by Kirk Thatcher, an associate producer on Star Trek IV, in honor of unit production manager Mel Efros.
