Okay, not even going to bother lying here. Joker is my favorite comic book character doll to date.
I loved his design on paper and it took some substantial will power to not work on him right away. He's this great combination of cute and creepy that not many of my dolls have and I just love it. Partly due to him being one of the few dolls to have a mouth.
His outfit features what I call in my head 'Ten Layering', as my Tenth Doctor doll was the first one to have the illusion of multiple clothing layers. First to have a tiny bow for the collar though. His playing cards are just tiny printed versions from the basic card deck that we all have laying around the house somewhere.
