This is a minifig scale from the movie Robocop. must be the best robot bad guy ever! The shoulders, elbows, waist, hips and toes(!) are all articulated. Many thanks to Billyburg for a tip on the leg pistons.
Mobile Frame Zero: Rapid Attack sounds like a Japanese game involving giant robots and, well, that's not terribly far off from the truth. Only it's not a video game, it's a tabletop game. And instead of using plastic pieces, it uses LEGO.
