So I have an unfortunately uncredited cosplay of Dee Dee, from Batman Beyond. Delia Dennis and Deidre Dennis were the twin granddaughters of Harley Quinn who were a chip off the old block you may say. They followed the Joker and harassed the new Batman in the same precocious manor that their grandmother did all those years before.
They get the nod this week because this pic made me smile as I enjoyed Batman Beyond and I like it when somewhat obscure characters I’ve enjoyed get featured by cosplayers. I found this pic from the Animate Miami Supercon on Tumblr.
