Bat-Mite is a fictional character appearing in stories published by DC Comics. The character made his first appearance in Detective Comics #267 (May 1959) in a story titled "Batman Meets Bat-Mite" written by Bill Finger, with art by Sheldon Moldoff. Bat-Mite is an Imp similar to the Superman villain Mister Mxyzptlk. Appearing as a small childlike man in an ill-fitting costume, Bat-Mite possesses what appears to be near-infinite magical power, but in reality is highly-advanced technology from the fifth dimension that cannot be understood by our limited three-dimensional views. Unlike Mxyzptlk, Bat-Mite idolizes his superhero target and thus he has visited Batman on various occasions, often setting up strange events so that he could see his hero in action. Bat-Mite is more of a nuisance than a supervillain, and often departs of his own accord upon realizing that he has angered his idol.
