After talking about this with some people via PMs, I have decided to make a thread for this. Recently I got this idea: Cosmic Terror - Star Trek / H.P. Lovecraft crossover. That is not dead which can eternal lie, And with strange aeons even the final frontier may die. The world of Star Trek in Cthulhu Mythos. Now, this isn't a plot bunny, but rather me wanting to discuss the entire concept of crossing these two universes. Star Trek is ultimately an optimistic tale. Going boldly where no man has gone before, exploring new worlds and meeting new races, promoting unity. There is a greater purpose. The world of Lovecraft mythos on the other hand paints a pessimistic picture. Humanity is an accident, perhaps even a joke. There are dark, elder gods which don't even notice us because we are so small. Humanity is doomed and its existence has no meaning. This strong contrast is what made me think of a crossover. How would the Can-Do, optimistic and friendly Federation fare in a dark, horrible, eldritch universe? CheddarTrek mentioned that reconciling the existence of the Q-continuum with entities such as Nyarlathotep, Azatoth or Cthulu may prove difficult.
