Spoiler Alert for those not having seen the film yet.
In the 2022 film The Batman, Bruce Wayne is not yet known as Batman but introduces himself as Vengeance:
The letters are addressed to To the Batman:
Important note for me: To the Batman and not To Batman, i.e. the Riddler implicates the costume and is not calling him Batman. Does the form of Vengeance appear in comics or is this a new interpretation in the film?
