Q
The Q are a super race that have taken an interest in humans for unknown reasons. Q is also the name used by the most frequently encountered member of this race.
Racial Attributes
Q apparently have the ability to move themselves and other objects through space and time without visible effort. They can also manipulate matter and energy, allowing them to transform objects, apply force, and alter temperatures at will. They can even create extensive virtual environments with self-motivated fictional characters.[1]
Q are ageless, immune to all known diseases, and able to function normally in any known environment. Although they freely describe themselves as "omnipotent", the Q definitely have limitations, one of the most obvious being other Q. Q can combine efforts to harm other members of their race or even deprive individual Q of their powers.
The Q normally dwell in an alternate dimension which is supposedly incomprehensible to humans. Human visitors subjectively interpret their experience of the "Q Continuum" based on prevailing conditions in that realm and their own cultural background.
The source of Q powers is unknown, but some kind of technology seems to be involved, since they can arm human visitors with "Q weaponry" capable of harming the Q[2].
Individual Q
Q interests in regarding the human race are normally handled by a single representative. This individual has a history of insulting, tormenting, taunting, and otherwise harassing races all over the Milky Way[3].
