Harry Potter - Black Slytherin Robe and Short Legs (Gregory Goyle Transformation)

Harry in Slytherin robes represents one of the earliest moments in the series when identity becomes physically unstable. Polyjuice Potion turns Harry into Gregory Goyle so he can enter the Slytherin common room, and LEGO translates that scene through interchangeable minifigure parts and dual expressions. The black-and-green uniform is intentionally ordinary; the interest lies in who is supposed to be inside it. That makes this figure almost a lesson in the logic of LEGO itself: bodies, faces, hair, and clothing are modular, so disguise and transformation feel unusually natural in brick form.
