The Dark Knight's alter ego, Bruce Wayne is a business tycoon (he inherited it and has great upper management) by day, a playboy (left) by evening and a crime fighter by night.

After seeing a movie with his parents as a child, the family is beset by a quintessential "bad guy" who kills Bruce's parents and leaves him alive. Completely crushed by this event, Bruce promises to do something about crime, eventually studying criminology, martial arts, forensics science, magic (have to pull plenty of Houdini's to be a vigilante) as well as plenty of physical training.

On the left he's shown in his typical playboy heartbreaker tux.

TOP FIGURE:
Bruce is made from a Joker body and a Bruce Wayne head. The flower and bolo from the Joker have been sanded off. The bow tie was added with Super Sculpy.

BOTTOM FIGURE:
Bruce is made from a Two-Face body and a Bruce Wayne head. The tie was narrowed a bit with the X-acto and some sand paper. I took this paint scheme off of his trading card since most people do his usual brown suit with the yellow shirt. Just thought I'd be a bit different since this is a common enough custom.
Unfortunately, a few people have pointed out that this suit scheme is the same as Clark Kent's usual.

Others have asked about the background for this photo -- it's an old Fisher Price dollhouse from the eighties, complete with Fisher Price furniture (which, unfortunately, is a bit too small to really be in scale).
