Bat-Mite (DC)

 Bat-Mite is a hero and villain, but rather then being a true supervillian heres rather a nusance to Batman. 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 humans' 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.
