I made this red one first when I was bored one day. The other two are near-identical copies:
The blue one is a true clone of the first, and it is my personal favorite, partially because of the swords on his spear and partially because the colors look so crisp. (though the wings blend in with the white background):
This black one is almost identical to the others, but has slightly different elbow joints since I ran out of wrenches (you didn't notice, did you?).
A back view of the red one; you can see the jet engines on the back and legs. The wings on the arms are meant to meld with those on his back:
