On another board somebody was sketching typical video game enemy clichés like Slimes and Skeletons. I suggested "late game heavily armored giants" (like FF Iron Giants, OoT Iron Knuckles, Titanus FE3H)
He wasn't happy with his first attempt so I gave him some editing fun I made for a reference, and I love how the final sketch came out.

I'd love it if somebody could complete the drawing. Feel free to make changes if you feel they're for the best as long as it's in the same ballpark.
