10 Best One Time Only Characters In Batman: The Animated Series
8. Randa Duane
Randa Duane falls into two distinct categories: at first blush she, like Selina Kyle, seems like a perfect romantic interest for Bruce Wayne, but dig a little deeper and you discover that she is actually quite a conniving villainess.
Introduced in the two-part episode, Heart of Steel, Randa is ostensibly the personal assistant of Karl Rossum, Head of Cybertron Industries. However, Ms Duane is far more loyal to Rossum's supercomputer, H.A.R.D.A.C., which is scheming to replace every living person in the world with robots. On the plus side, she is still perfectly capable of enjoying a romantic dinner for two with Bruce Wayne.
There is far more to tell about Randa's character, but that would be a major spoiler.
Her voice actress, Leslie Easterbrook, instils a terrific sense of allure and subtle deceit in Randa Duane, making it absolutely clear why both Batman and Bruce Wayne would be attracted to this particular femme fatale. Indeed, Randa would be a perfect partner for Bruce, if only she were...oops, that almost gave the big surprise away!
