Re: Khan the most dangerous enemy of the original crew?
I suppose it could be interpreted as really meaning most dangerous for the crew, rather than in general. Which would still be debatable. But he was the only one who ever succeeded in actually killing a main character...
Nomad killed Scotty.
Knight killed McCoy.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
