Holy Bat-Doll, Batman!
This first appearance Batman figure/doll came out in 2000. It came in a deluxe box- set with a hardcover book (Batman: The Golden Age by Les Daniels) about the history of Batman, and a reprint of Batman #1.
He's much like an old school GI Joe or Mego type figure (I assume, although I have no old school GI Joes or Megos to compare.) His cape has wires inside the sides to shape it, and his Batarang fits snugly into a compartment on his belt.
He's really well articulated and quite a nice representation of Batman's first appearance.
