Maybe I'm reading too much into it, but I think the Khan and Gene War episodes from TOS were inspired from events and characters indirectly told in Robert A Heinlein's Utopian novel "Beyond This Horizon", which is about the wonders of applied genetics/eugenics and Social Credit. In the novel, dictators from the past "Second Genetic War" (briefly mentioned as part of the World's history) are called "The Great Khans". Those Khans used, unlike the good side in the war, genetics in order to create supersoldiers, as well specific workers for different tasks (similar to Aldous Huxley's "A Brave New World").

The TNG episode "Conspiracy" must have, at least indirectly, been inspired by Heinlein's "The Puppet Masters", the invasion story about alien slugs taking over people's bodies.

"Batman is only meaningful as an answer to a world which in its basics is chaotic and in the hands of the wrong people, where no justice can be found. I think it's very suitable to our perception of the world's condition today... Batman embodies the will to resist evil" -Frank Miller
