Whenever we get a peek at a leaked Mountain Dew photo, we usually at least know what the flavor is. In this case, however, it's a huge mystery. The soda itself is dark blue with a green cap and details. The drink color reminds us of the Mountain Dew Dark Berry that was released in 2012 for The Dark Knight Rises film. The mixed berry flavor was apparent in the name, but Riddler's Brew isn't giving us too many clues.
