Lego Batman is a theme and product range of the Lego construction toy, introduced in 2006, based on the superhero character Batman, under license from DC Comics. The sets feature vehicles, characters and scenes from the comics and films. The inspirations for the design of these varies widely. For example, the Batmobile retains its basic sleek shape and prominent fins from the Tim Burton films, whereas the "Bat-Tank" seems to be based on the tank-like Batmobile in Frank Miller's The Dark Knight Returns. In 2008, a video game based on the theme, Lego Batman: The Videogame, was released, along with four new sets. The theme was relaunched in early 2012 as part of the Lego DC Universe Superheroes line, which is a sub-theme of the Lego Super Heroes line. In total there were seventeen sets, almost all of them including Batman.
