Q vs Spectre
Q-In the Star Trek fictional universe, the Q are a race of omnipotent, immortal and omniscient godlike beings from a parallel existence called the Q Continuum. ("I have complete control over space, matter and time" -Q2). They are largely indifferent to the affairs of the non-Q beings living in normal space living in the many dimensions parallel to their own, considering them to be insignificant and childlike with a few exceptions. The Q have appeared on episodes of Star Trek: The Next Generation, Star Trek: Deep Space Nine, Star Trek: Voyager, and possibly even the original Star Trek (see below).
The most notable of these is Q as played by John de Lancie, a mischievous Q who periodically harasses the crews of starships and space stations. He also has a flair for the dramatic, whisking away the crew to exotic locations, engaging in elaborate speeches, and snapping his fingers to engender many of his manifestations.
