Microfigures are a smaller type of minifigure used mainly in the LEGO Games theme. Being only two bricks tall and 1x1 at the base, they allow for game boards to be smaller than otherwise. Most microfigures are original, though some are based on existing minifigure characters such as Harry Potter, The Lord of the Rings and Ninjago ninja. They are used in almost every LEGO game.
