Mr. Mxyzptlk is an imp from the 5th Dimension. He has magical powers which is normal for a man native to his dimension. Although mostly just a practical joker, his playful escapades have endangered many lives, so giving him the supervillain title would not at all be inappropriate. He only has one weakness, if he is tricked into saying his name backward, then he will be banished back to the 5th Dimension. However, this banishment will only last three months, and after that three month period is up, he will be able to return to the 3rd dimension. Time and time again he has pestered the JLA, only to be defeated each time.
