The LEGO Duplo Batman theme is a subset of the LEGO Duplo line that centers around the character Batman and elements from his universe. These sets, designed for younger children, include larger, child-friendly pieces that represent Batman, his allies, adversaries, and associated vehicles and locales. The theme offers a simplified introduction to the world of Batman.
The LEGO DUPLO theme is designed for children ages 1 to 5. It features DUPLO figures which are much larger than minifigures and DUPLO blocks which are about twice the length, width, and height of a standard System brick.
