Now I like how Amazo was interpreted on the Justice League Unlimited show and the character pretty much kept the same abilities as his comic book counterpart but to me he just didn't look the part.
The 'real' Amazo's body is a Bruce Wayne from 'The Batman'  animated series line. His head is a Captain Shang from Disney's 'Mulan' line which has had modifications and sculpting. His wristbands are sculpted and clay was also added around the upper part of his waist. Scroll on down below for a size comparison with the other Amazo. The custom is just about the perfect height as Amazo in the books is quite tall and usually towers over his foes in the League, I'm quite pleased with him.
