I would personally like to see Hush in the next Batman movie or The Black Mask.The Riddler is a wimp,and either one of those two would take it to Batman just as bad as The Joker did plus it would open the door for The Joker to return.Which would be great.It would also open the door for Catwoman because she is the one who actually kills Black Mask in the comics.Hush however releases The Joker from Archam with the help of Scarecrow and Harley Quinn.Both compelling storylines.The Riddler is just to week.
