This LEGO Batman - Riddler figurine is the perfect addition to any LEGO collection. He is in a striking green suit with a bright purple tie, and he has a black mask above his eyes. On his chest is a large green question mark, adding a playful touch. In his right hand, he is holding his signature black cane. When it comes to coloring, use shades of green for his suit, perhaps with purple for his tie and dark grey for his mask. Accent the question mark with yellow and make the cane stand out with black or brown. Adding some extra white highlights around the edges can really bring the figure to life. Whatever colors you choose, this Riddler's shape and details will make him stand out even more.
