Today, LEGO introduced a new series of sets in the Star Wars line, which they’re calling “Buildable Figures.” They’re basically more realistic (as far as LEGO goes) versions of the Star Wars characters (i.e. not minifigures) built out of Technic parts and other large, custom-molded pieces. Other themes have had the “Buildable Figures” added to their lines as well, such as Superheroes and Chima.
They revealed Darth Vader and Luke Skywalker buildable figures today and hint at more reveals to come. The series will release in September of 2015.
