Batman's most prominent love interest throughout the years.
Vicki Vale first appeared in the Batman universe in the 1940s. Her character was created to mirror that of Lois Lane from the Superman comics. She is a reporter for the Gotham Gazette who's job it is to report on Batman and she is often attracted to the Dark Knight, and sometimes Bruce Wayne as well. She suspects they are one in the same, much like Lane does for Superman and Clark Kent.
In Tim Burton's Batman, Vicki Vale is played by Kim Basinger. She is Batman/Bruce Wayne's love interest. She learns the Bruce Wayne is in fact Batman and is the first person to ever be let into the Batcave besides Alfred. She does not make an appearance in any other live-action Batman movies.
In The Batman vs. Dracula, she is portrayed as a television reporter instead of her traditional job as a newspaper reporter.
Vale also appears in a couple of Wonder Woman comics, as well as special DC Comics issues.
