The original LEGO Batman theme was first released in 2006 and lasted until 2008 and features 15 sets, magnets, videos, books as well as toys released by McDonald's. Batman has been re-introduced in 2012 as part of the DC Super Heroes theme. The theme is based on Batman: The Animated Series but also include elements from other Batman universes, such as the Tumbler from the Christopher Nolan films. However, each set, aside from The Batcave: The Penguin and Mr. Freeze's Invasion, is based on scenarios that occurred on the show where each set features Batman fighting a villain.

The first wave of sets in 2006 included 7 sets and 3 magnets. In 2007 the next small wave came only having two sets, both introducing a brand new dark blue and light grey Batsuit with a new Bat-logo on the front of the suit along with a new belt. This wave also introduces new villains including Scarecrow, Bane, and The Riddler. The final wave in 2008 features sets off the then released Christopher Nolan movie the The Dark Knight. 2008 also featured Harley Quinn for the first time as well as the Batman video game in addition to the Comic-Con exclusive promotional set that featured minifigures of Batman and The Joker.
