The wings come from a Fi?ures Series 1 Knight, the head (complete with black eye!) and hair from a Fi?ures Series 1 Boxer, and the gloves are from a Fi?ures Series 1 Executioner. The yellow belt is from a random Knight I had in my spare parts pile, and the legs, torso and arms are from other random figures. He is holding a rope with a hook and a handheld computer too, more random pieces I had laying around.
I cut some electric tape into a bat symbol, but otherwise this Unmasked Batman is a simple parts swap custom!
Someday I will need to connect with someone with a 3D printer and get a Playmobil sized Bat-cowl made. I am surprised there aren't any sites online where people sell stuff like that, like there are with custom Lego parts, but I suppose Lego do have a bigger collector/customizing community at this point.
