It has been rumored that the Joker will be making an appearance in Batman: the Brave and the Bold. But Action Figure Insider has some photos of the upcoming line of Batman: B&B action figures that include the Clown Prince of Crime! Click on the image below to see images of Despero, Gentleman Ghost, the Atom and B'Wana Beast!
Not bad! Not as good as Batman: TAS but a hundred times better than The Batman. My guess is that the Joker shows up in the two part season finale: Deep Cover for Batman!/Game Over for Owlman!
On an aside, can anyone tell me why there are big holes in the sides of these figures? Have they given up trying to hide the joints?
