Weird costume choices "bug" me too. The whole insect hybrid look for Chameleon annoyed me. And again, in my hands, a decent paint job. Under the Sony's lens... pretty crappy. How did I even get that blue paint on his knee and not notice it?
This was done a while ago. I'm guessing now, but I believe the body is Brainiac 5 and the head is an untouched Chameleon head. The cross-eyed look was brought to us by the original manufacturer.
