The Q were a seemingly omnipotent and immortal species of Star Trek whose council was known as the Q Continuum.
The Q appear to be transcendent beings with these abilities:
- Alter reality around themselves and shapechange themselves and others, with instantaneous matter-energy transformation.
- Reverse time and entropy
- Teleport to any point in space and time
- Tweak natural laws (Q: "Simple. Just change the gravitational constant of the universe, thereby altering the mass of the asteroid.")
- Genius-level intellect (Q spectacularly claimed to possess an IQ of 2005)
Whoever encountered the Q must have thought they used magic; Picard, however, always found him annoying rather than fascinating.
