 Early concepts of the final showdown on Claw Island had a huge,  muscled, Riddler sitting on his throne when Batman finds him. The  Riddler twists the two skulls on his armrests and the Riddlers  muscled body is revealed to be a shell which splits in two, from  which the real Riddler (wearing his white and green jumpsuit) steps  out. This description made it into the junior novelization of the  movie by Alan Grant (I) (qv), and was also featured in the video  game based on the movie.
