Q

Q is a villain from Star Trek who is depicted as rogue member of the Q Collective - a society of godlike aliens who are nearly omnipotent by human-standards, Q loves to misuse his power and has the personality of a trickster villain: taking delight in causing mischief, in his first appearance he tried to put the entire crew of the USS Enterprise on trial for the crimes of humanity and ever since then he has taken to making trouble for them, especially Picard - who he seems to have a fondness for. He also caused trouble for other members of the Federation and innumerable other species, he got so bad that eventually the other members of the Q Collective removed his power - but he managed to get them back again and went back to his usual antics.
