Because Bruce Wayne is retired at the beginning of The Dark Knight Returns, we don’t get to see the suit right away. Instead we get to listen to a conversation between Bruce and a soon to be retired Commissioner James Gordon. When Bruce opens his mouth, we hear the gravely baritone voice of an old Robocop, which works perfectly with the character. Once he decides that he has had enough of the crime on the streets and suits up again, we see that just because Bruce got old, doesn’t mean he let himself go.
Harley Quinn: Best known as "The Joker's Girlfriend", Harley has had occasional romantic encounters with Batman, most notably her kiss with him in the episode Harley's Holiday from Batman: The Animated Series. Recently, in the The New 52, there have been a couple of stories in which Harley became infatuated either with Bruce Wayne or Batman. These attractions appear to be entirely one-sided and Batman has shown no signs of attraction towards Harley.
