This figure reused the Super Powers Joker figure body with a new head. This time he is wearing a red suit. He has some orange and blue details. The figure came with a pistol with a very long barrel (lost years ago), like the one he used in the '89 movie. He also featured a helicopter back pack that allows him to escape into the sky.
This helicopter back pack was reused from another Kenner toy. The cat burglar character Claw from the Police Academy line also came with this back pack molded in different colors. I believe Claw was released first. Kenner actually reused a lot of toys for the Dark Knight Collection. Lots of Super Power figures as well as vehicles from Robo Cop and Silver Hawks
