Review by JoshB
Big Duo is the enemy robot of Big O. The detailing on this figure is even better than Big O, but the large size of the arms get in the way. He can "Transform" into flight mode by removing the small wings and replacing them with larger ones. They do not fold into the arms. He only has one set of hands, but each finger on the can can move. Big Duo comes with a different Roger Smith figurine, as well as Angel.
