>>6197113here, look at Raiden, I'd say he's leaner than Deadpool and despite him being a cyborg with more body detail, he's actually the first revo to have the double-shoulder joint that gives it a much wider range than other revos. You can see that his shoulder muscle is actually draping over pretty well over the joints.
