Man-Bat also appears in ''The Batman ''as a more villainous character. In this version, Dr. Langstrom worked for Wayne Enterprises and had an obsession with Batman.

Batman managed to defeat him and he was sent t[[File:Man-Bat_(The_Batman).jpg|thumb|300px|Man-Bat in ''The Batman''.]]o Arkham. Later in the series Penguin used a sonar device to mentally control Langstrom in his Man-Bat form to commit robberies for him. Batman managed to stop them both. Eventually Langstrom renounced his criminal ways and helped Batman defeat the [[Terrible Trio]], who had stolen mutagen from Langstrom to get powers of their own.
