Il più grande fan di Batman, Bat-Mite, diventa il suo più grande incubo quando, sbucando dalla quinta dimensione, scatena il caos in città nel tentativo di aiutare Batman a diventare un eroe migliore.

Batman and Zatanna make short work of Abra Kadabra. Later, Batman must choose between justice and vengeance when he confronts Joe Chill the man who murdered his parents.

Bat-Mite hosts a series of Batman's most bizarre adventures including the Mad Magazine-inspired Batboy and Rubin, a Japanese-influenced Bat-Manga and a guest starring role from the Scooby Gang and Weird Al Yankovic.

After a team up with Space Ghost and his companions, Batman must come to the aid of three of his fellow superheroes who have fallen into the icy clutches of Mr. Freeze.

Bat-Mite tries to make the show so horrible it has to be cancelled.
