A key character from 1989’s Batman, surprisingly, has not appeared in and of the iconic film’s subsequent properties, but perhaps she should. A classic Batman supporting character from the comics plays a major role in Tim Burton’s genre-redefining Batman, serving as an audience surrogate and having a major effect on Bruce Wayne’s character arc. Unfortunately, Batman Returns and all other material from the Burton duology’s branching timeline omits this character, though they can and should reappear in some form or another.
