ACE is a reworked 'Ace' from a BB figure deluxe pack...he was sanded into swiss cheese, then filled with epoxy, and finally painted.
THE CHIMERA/DR. CUVIER was made from a 10" JLU Batman...the tail is a bike inner tube with a coat hanger inside for poseability...the neck, nose and waist is epoxy...the ears were cut off, then reglued at proper angle.
BATMAN just wanted more photo time!
