A Lego minifigure, often simply referred to as a Lego figure or a minifig, is a small plastic articulated figurine made of special Lego bricks produced by Danish building toy manufacturer The Lego Group. They were first produced in 1978 and have been a success, with over 4 billion produced worldwide as of 2020. Minifigures are usually found within Lego sets, although they are also sold separately as collectables in blind bags , or can be custom-built in Lego stores and on lego.com. While some are named as specific characters, either licensed from already existing franchises or of Lego's own creation, many are unnamed and are designed simply to fit within a certain theme . They are highly customizable, and parts from different figures can be mixed and matched, resulting in many combinations.
