Mountain Dew Riddler's Brew is intended as a tie-in drink to the upcoming movie The Batman, which itself currently slated for a release in 2022.
The drink was first leaked in mid-2020, at a time when the movie was planned to release in October 2021. Due to the movie's delay, it is unknown if, or when, this product will release.
A separate drink, Dark Berry, was similarly released for a Batman movie, in its case, The Dark Knight Rises.
