That one's also my favorite and not just cause of nostalgia.
I thought a lot about what I like in a Cyborg design and I appreciate the various elements of the cartoon's look. I enjoy the use of blues and several colors.
Like you look at the New 52 design and the movie and its way too much silver. It makes him look like a mess of shrapnel while here its not hard on the eyes. It has a more palatable armor design.
