For questions about the Q are an omnipotent alien race in the Star Trek universe that have miraculous (currently unexplained) powers to control space, time and energy. Always use in conjunction with the [star-trek] tag. Only use for questions about the Q not those that simply mention them.

Q refers to both the name of this incredibly advanced trans-dimensional alien race and also to each member of their race.

They live in the Q Continuum (which exists in another dimension) and treat other races (both physical and non-corporeal) with indifference.

They are considered to be omnipotent, immortal and omniscient, though they can be killed or stripped of their powers by other Q.
