This Batman Beyond spliced with a heavy dose of Vampire Bat DNA from the Batman Beyond animated series episode "Splicers".
I started with an angel body and pulled off his head, arms, legs, and wings. I added a reshaped Parademon head, and parademon arms and legs. The wings were made of foam pieces. Chest symbol, pant rips, and pinky fingers sculped with apoxie. Painted with citadel paints. Made sure to gloss up what was left of the batman suit to match the batman beyond figures. Ordinarily I'd be the first to protest against having a glossy BB, but..hey I just love the feel of 'ardcoat and how it makes the textures different from his arm/legs. ^_^
I made a cast of Batman Beyond's head out of apoxie, and then made a claw print in the back so that the Spliced Batman Beyond could hold it in his hand.
