The Batman: 9 Things That Are Impossible If Ben Affleck Returns
5. The Best Kind Of Riddler Story
After Jim Carrey's divisive performance as The Riddler in Batman Forever, it's about time we got to see the iconic character appear in another Batman movie. The best way for him to do that is for him to appear in Gotham for the first time and to challenge Batman to a deadly battle of wits without precedent, for maximum shock factor.
For maximum effect, Batman has to have no expectations of The Riddler's behaviour, because otherwise it's immediately recognisable as him. To know The Riddler is to conquer him, so his first appearance in the DCEU HAS to be his first foray into Gotham. He can't have appeared before.
Unfortunately, The Riddler already exists in this universe. His tag was spotted in Batman v Superman after all, and as Snyder's most jingoistic fans will tell you, EVERY brush-stroke he made, whether foreground detail or background Easter Egg, means something of substance.
So The Riddler has already operated, in some form, and he's probably out of the running to appear in The Batman for that very reason.
